    public interface ResultSet
extends Wrapper, AutoCloseable
    A table of data representing a database result set, which is usually generated by executing a statement that queries the database.

    A ResultSet object maintains a cursor pointing to its current row of data. Initially the cursor is positioned before the first row. The next method moves the cursor to the next row, and because it returns false when there are no more rows in the ResultSet object, it can be used in a while loop to iterate through the result set.

    A default ResultSet object is not updatable and has a cursor that moves forward only. Thus, you can iterate through it only once and only from the first row to the last row. It is possible to produce ResultSet objects that are scrollable and/or updatable. The following code fragment, in which con is a valid Connection object, illustrates how to make a result set that is scrollable and insensitive to updates by others, and that is updatable. See ResultSet fields for other options. 

    
       Statement stmt = con.createStatement(
                                      ResultSet.TYPE_SCROLL_INSENSITIVE,
                                      ResultSet.CONCUR_UPDATABLE);
       ResultSet rs = stmt.executeQuery("SELECT a, b FROM TABLE2");
       // rs will be scrollable, will not show changes made by others,
       // and will be updatable
    The ResultSet interface provides getter methods (getBoolean, getLong, and so on) for retrieving column values from the current row. Values can be retrieved using either the index number of the column or the name of the column. In general, using the column index will be more efficient. Columns are numbered from 1. For maximum portability, result set columns within each row should be read in left-to-right order, and each column should be read only once.

    For the getter methods, a JDBC driver attempts to convert the underlying data to the Java type specified in the getter method and returns a suitable Java value. The JDBC specification has a table showing the allowable mappings from SQL types to Java types that can be used by the ResultSet getter methods.

    Column names used as input to getter methods are case insensitive. When a getter method is called with a column name and several columns have the same name, the value of the first matching column will be returned. The column name option is designed to be used when column names are used in the SQL query that generated the result set. For columns that are NOT explicitly named in the query, it is best to use column numbers. If column names are used, the programmer should take care to guarantee that they uniquely refer to the intended columns, which can be assured with the SQL AS clause.

    A set of updater methods were added to this interface in the JDBC 2.0 API (Java™ 2 SDK, Standard Edition, version 1.2). The comments regarding parameters to the getter methods also apply to parameters to the updater methods.

    The updater methods may be used in two ways:

    1. to update a column value in the current row. In a scrollable ResultSet object, the cursor can be moved backwards and forwards, to an absolute position, or to a position relative to the current row. The following code fragment updates the NAME column in the fifth row of the ResultSet object rs and then uses the method updateRow to update the data source table from which rs was derived. 
      
       rs.absolute(5); // moves the cursor to the fifth row of rs
       rs.updateString("NAME", "AINSWORTH"); // updates the
          // NAME column of row 5 to be AINSWORTH
       rs.updateRow(); // updates the row in the data source
    2. to insert column values into the insert row. An updatable ResultSet object has a special row associated with it that serves as a staging area for building a row to be inserted. The following code fragment moves the cursor to the insert row, builds a three-column row, and inserts it into rs and into the data source table using the method insertRow. 
      
       rs.moveToInsertRow(); // moves cursor to the insert row
       rs.updateString(1, "AINSWORTH"); // updates the
          // first column of the insert row to be AINSWORTH
       rs.updateInt(2,35); // updates the second column to be 35
       rs.updateBoolean(3, true); // updates the third column to true
       rs.insertRow();
       rs.moveToCurrentRow();

    A ResultSet object is automatically closed when the Statement object that generated it is closed, re-executed, or used to retrieve the next result from a sequence of multiple results.

    The number, types and properties of a ResultSet object's columns are provided by the ResultSetMetaData object returned by the ResultSet.getMetaData method.

    • Method Detail

      • next

        boolean next​()
      throws SQLException
        Moves the cursor forward one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.

        When a call to the next method returns false, the cursor is positioned after the last row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown. If the result set type is TYPE_FORWARD_ONLY, it is vendor specified whether their JDBC driver implementation will return false or throw an SQLException on a subsequent call to next.

        If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.

        Returns:
        true if the new current row is valid; false if there are no more rows
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

      • close

        void close​()
    throws SQLException
        Releases this ResultSet object's database and JDBC resources immediately instead of waiting for this to happen when it is automatically closed.

        The closing of a ResultSet object does not close the Blob, Clob or NClob objects created by the ResultSet. Blob, Clob or NClob objects remain valid for at least the duration of the transaction in which they are created, unless their free method is invoked.

        When a ResultSet is closed, any ResultSetMetaData instances that were created by calling the getMetaData method remain accessible.

        Note: A ResultSet object is automatically closed by the Statement object that generated it when that Statement object is closed, re-executed, or is used to retrieve the next result from a sequence of multiple results.

        Calling the method close on a ResultSet object that is already closed is a no-op.

        Specified by:
        close in interface AutoCloseable
        Throws:
        SQLException - if a database access error occurs

      • wasNull

        Returns:
        true if the last column value read was SQL NULL and false otherwise
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

        Retrieves the value of the designated column in the current row of this ResultSet object as a stream of ASCII characters. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC driver will do any necessary conversion from the database format into ASCII.

        Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.

        Parameters:
        columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
        Returns:
        a Java input stream that delivers the database column value as a stream of one-byte ASCII characters. If the value is SQL NULL, the value returned is null.

        Deprecated. use getCharacterStream instead
        Retrieves the value of the designated column in the current row of this ResultSet object as a stream of two-byte Unicode characters. The first byte is the high byte; the second byte is the low byte. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARCHAR values. The JDBC technology-enabled driver will do any necessary conversion from the database format into Unicode.

        Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method InputStream.available is called, whether there is data available or not.

        Parameters:
        columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
        Returns:
        a Java input stream that delivers the database column value as a stream of two-byte Unicode characters. If the value is SQL NULL, the value returned is null.
        Throws:
        SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

        Retrieves the value of the designated column in the current row of this ResultSet object as a stream of uninterpreted bytes. The value can then be read in chunks from the stream. This method is particularly suitable for retrieving large LONGVARBINARY values.

        Note: All the data in the returned stream must be read prior to getting the value of any other column. The next call to a getter method implicitly closes the stream. Also, a stream may return 0 when the method available is called whether there is data available or not.

        Parameters:
        columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
        Returns:
        a Java input stream that delivers the database column value as a stream of uninterpreted bytes; if the value is SQL NULL, the result is null
        Throws:
        SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set

      • getWarnings

        SQLWarning getWarnings​()
                throws SQLException
        Retrieves the first warning reported by calls on this ResultSet object. Subsequent warnings on this ResultSet object will be chained to the SQLWarning object that this method returns.

        The warning chain is automatically cleared each time a new row is read. This method may not be called on a ResultSet object that has been closed; doing so will cause an SQLException to be thrown.

        Note: This warning chain only covers warnings caused by ResultSet methods. Any warning caused by Statement methods (such as reading OUT parameters) will be chained on the Statement object.

        Returns:
        the first SQLWarning object reported or null if there are none
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

      • clearWarnings

        void clearWarnings​()
            throws SQLException
        Clears all warnings reported on this ResultSet object. After this method is called, the method getWarnings returns null until a new warning is reported for this ResultSet object.
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

      • getCursorName

        String getCursorName​()
              throws SQLException
        Retrieves the name of the SQL cursor used by this ResultSet object.

        In SQL, a result table is retrieved through a cursor that is named. The current row of a result set can be updated or deleted using a positioned update/delete statement that references the cursor name. To insure that the cursor has the proper isolation level to support update, the cursor's SELECT statement should be of the form SELECT FOR UPDATE. If FOR UPDATE is omitted, the positioned updates may fail.

        The JDBC API supports this SQL feature by providing the name of the SQL cursor used by a ResultSet object. The current row of a ResultSet object is also the current row of this SQL cursor.

        Returns:
        the SQL name for this ResultSet object's cursor
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • getMetaData

        Retrieves the number, types and properties of this ResultSet object's columns.
        Returns:
        the description of this ResultSet object's columns
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

      • getObject

        Object getObject​(int columnIndex)
          throws SQLException

        Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.

        This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.

        This method may also be used to read database-specific abstract data types. In the JDBC 2.0 API, the behavior of method getObject is extended to materialize data of SQL user-defined types.

        If Connection.getTypeMap does not throw a SQLFeatureNotSupportedException, then when a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()). If Connection.getTypeMap does throw a SQLFeatureNotSupportedException, then structured values are not supported, and distinct values are mapped to the default Java class as determined by the underlying SQL type of the DISTINCT type.

        Parameters:
        columnIndex - the first column is 1, the second is 2, ...
        Returns:
        a java.lang.Object holding the column value
        Throws:
        SQLException - if the columnIndex is not valid; if a database access error occurs or this method is called on a closed result set

      • getObject

        Object getObject​(String columnLabel)
          throws SQLException

        Gets the value of the designated column in the current row of this ResultSet object as an Object in the Java programming language.

        This method will return the value of the given column as a Java object. The type of the Java object will be the default Java object type corresponding to the column's SQL type, following the mapping for built-in types specified in the JDBC specification. If the value is an SQL NULL, the driver returns a Java null.

        This method may also be used to read database-specific abstract data types.

        In the JDBC 2.0 API, the behavior of the method getObject is extended to materialize data of SQL user-defined types. When a column contains a structured or distinct value, the behavior of this method is as if it were a call to: getObject(columnIndex, this.getStatement().getConnection().getTypeMap()).

        Parameters:
        columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
        Returns:
        a java.lang.Object holding the column value
        Throws:
        SQLException - if the columnLabel is not valid; if a database access error occurs or this method is called on a closed result set

    throws SQLException
        Retrieves the current row number. The first row is number 1, the second number 2, and so on.

        Note:Support for the getRow method is optional for ResultSets with a result set type of TYPE_FORWARD_ONLY

        Returns:
        the current row number; 0 if there is no current row
        Throws:
        SQLException - if a database access error occurs or this method is called on a closed result set

      • absolute

        boolean absolute​(int row)
          throws SQLException
        Moves the cursor to the given row number in this ResultSet object.

        If the row number is positive, the cursor moves to the given row number with respect to the beginning of the result set. The first row is row 1, the second is row 2, and so on.

        If the given row number is negative, the cursor moves to an absolute row position with respect to the end of the result set. For example, calling the method absolute(-1) positions the cursor on the last row; calling the method absolute(-2) moves the cursor to the next-to-last row, and so on.

        If the row number specified is zero, the cursor is moved to before the first row.

        An attempt to position the cursor beyond the first/last row in the result set leaves the cursor before the first row or after the last row.

        Note: Calling absolute(1) is the same as calling first(). Calling absolute(-1) is the same as calling last().

        Parameters:
        row - the number of the row to which the cursor should move. A value of zero indicates that the cursor will be positioned before the first row; a positive number indicates the row number counting from the beginning of the result set; a negative number indicates the row number counting from the end of the result set
        Returns:
        true if the cursor is moved to a position in this ResultSet object; false if the cursor is before the first row or after the last row
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • relative

        boolean relative​(int rows)
          throws SQLException
        Moves the cursor a relative number of rows, either positive or negative. Attempting to move beyond the first/last row in the result set positions the cursor before/after the the first/last row. Calling relative(0) is valid, but does not change the cursor position.

        Note: Calling the method relative(1) is identical to calling the method next() and calling the method relative(-1) is identical to calling the method previous().

        Parameters:
        rows - an int specifying the number of rows to move from the current row; a positive number moves the cursor forward; a negative number moves the cursor backward
        Returns:
        true if the cursor is on a row; false otherwise
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method
        Since:
        1.2

      • previous

        boolean previous​()
          throws SQLException
        Moves the cursor to the previous row in this ResultSet object.

        When a call to the previous method returns false, the cursor is positioned before the first row. Any invocation of a ResultSet method which requires a current row will result in a SQLException being thrown.

        If an input stream is open for the current row, a call to the method previous will implicitly close it. A ResultSet object's warning change is cleared when a new row is read.

        Returns:
        true if the cursor is now positioned on a valid row; false if the cursor is positioned before the first row
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed result set or the result set type is TYPE_FORWARD_ONLY
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • refreshRow

        void refreshRow​()
         throws SQLException
        Refreshes the current row with its most recent value in the database. This method cannot be called when the cursor is on the insert row.

        The refreshRow method provides a way for an application to explicitly tell the JDBC driver to refetch a row(s) from the database. An application may want to call refreshRow when caching or prefetching is being done by the JDBC driver to fetch the latest value of a row from the database. The JDBC driver may actually refresh multiple rows at once if the fetch size is greater than one.

        All values are refetched subject to the transaction isolation level and cursor sensitivity. If refreshRow is called after calling an updater method, but before calling the method updateRow, then the updates made to the row are lost. Calling the method refreshRow frequently will likely slow performance.

        Throws:
        SQLException - if a database access error occurs; this method is called on a closed result set; the result set type is TYPE_FORWARD_ONLY or if this method is called when the cursor is on the insert row
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method or this method is not supported for the specified result set type and result set concurrency.

      • moveToInsertRow

        void moveToInsertRow​()
              throws SQLException
        Moves the cursor to the insert row. The current cursor position is remembered while the cursor is positioned on the insert row. The insert row is a special row associated with an updatable result set. It is essentially a buffer where a new row may be constructed by calling the updater methods prior to inserting the row into the result set. Only the updater, getter, and insertRow methods may be called when the cursor is on the insert row. All of the columns in a result set must be given a value each time this method is called before calling insertRow. An updater method must be called before a getter method can be called on a column value.
        Throws:
        SQLException - if a database access error occurs; this method is called on a closed result set or the result set concurrency is CONCUR_READ_ONLY

        The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead the updateRow or insertRow methods are called to update the database.

        Note: Consult your JDBC driver documentation to determine if it might be more efficient to use a version of updateNClob which takes a length parameter.

        Parameters:
        columnLabel - the label for the column specified with the SQL AS clause. If the SQL AS clause was not specified, then the label is the name of the column
        reader - An object that contains the data to set the parameter value to.
        Throws:
        SQLException - if the columnLabel is not valid; if the driver does not support national character sets; if the driver can detect that a data conversion error could occur; this method is called on a closed result set; if a database access error occurs or the result set concurrency is CONCUR_READ_ONLY
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • getObject

        <T> T getObject​(int columnIndex,
                Class<T> type)
         throws SQLException

        Retrieves the value of the designated column in the current row of this ResultSet object and will convert from the SQL type of the column to the requested Java data type, if the conversion is supported. If the conversion is not supported or null is specified for the type, a SQLException is thrown.

        At a minimum, an implementation must support the conversions defined in Appendix B, Table B-3 and conversion of appropriate user defined SQL types to a Java type which implements SQLData, or Struct. Additional conversions may be supported and are vendor defined.

        Type Parameters:
        T - the type of the class modeled by this Class object
        Parameters:
        columnIndex - the first column is 1, the second is 2, ...
        type - Class representing the Java data type to convert the designated column to.
        Returns:
        an instance of type holding the column value
        Throws:
        SQLException - if conversion is not supported, type is null or another error occurs. The getCause() method of the exception may provide a more detailed exception, for example, if a conversion error occurs
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method

      • updateObject

        default void updateObject​(int columnIndex,
                          Object x,
                          SQLType targetSqlType,
                          int scaleOrLength)
                   throws SQLException
        Updates the designated column with an Object value. The updater methods are used to update column values in the current row or the insert row. The updater methods do not update the underlying database; instead the updateRow or insertRow methods are called to update the database.

        If the second argument is an InputStream then the stream must contain the number of bytes specified by scaleOrLength. If the second argument is a Reader then the reader must contain the number of characters specified by scaleOrLength. If these conditions are not true the driver will generate a SQLException when the statement is executed.

        The default implementation will throw SQLFeatureNotSupportedException

        Parameters:
        columnIndex - the first column is 1, the second is 2, ...
        x - the new column value
        targetSqlType - the SQL type to be sent to the database
        scaleOrLength - for an object of java.math.BigDecimal , this is the number of digits after the decimal point. For Java Object types InputStream and Reader, this is the length of the data in the stream or reader. For all other types, this value will be ignored.
        Throws:
        SQLException - if the columnIndex is not valid; if a database access error occurs; the result set concurrency is CONCUR_READ_ONLY or this method is called on a closed result set
        SQLFeatureNotSupportedException - if the JDBC driver does not support this method; if the JDBC driver does not support the specified targetSqlType
