    public class SQLWarning
    extends SQLException

    An exception that provides information on database access warnings. Warnings are silently chained to the object whose method caused it to be reported.

    Warnings may be retrieved from Connection, Statement, and ResultSet objects. Trying to retrieve a warning on a connection after it has been closed will cause an exception to be thrown. Similarly, trying to retrieve a warning on a statement after it has been closed or on a result set after it has been closed will cause an exception to be thrown. Note that closing a statement also closes a result set that it might have produced.

    Since:
    1.1

                          String SQLState,
                          int vendorCode)
        Constructs a SQLWarning object with a given reason, SQLState and vendorCode. The cause is not initialized, and may subsequently be initialized by a call to the Throwable.initCause(java.lang.Throwable) method.
        Parameters:
        reason - a description of the warning
        SQLState - an XOPEN or SQL:2003 code identifying the warning
        vendorCode - a database vendor-specific warning code
