Method Details

getDropSequenceString

public String getDropSequenceString(String sequenceName)

Description copied from class: Dialect

Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.getDropSequenceStrings(java.lang.String) to help facilitate that.

Dialects which support sequences and can drop a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to drop a sequence should instead override Dialect.getDropSequenceStrings(java.lang.String).

Overrides:

getDropSequenceString in class InterbaseDialect

Parameters:

sequenceName - The name of the sequence

Returns:

The sequence drop commands

getLimitString

public String getLimitString(String sql,
 boolean hasOffset)

Description copied from class: Dialect

Apply s limit clause to the query.

Typically dialects utilize variable limit clauses when they support limits. Thus, when building the select command we do not actually need to know the limit or the offest since we will just be using placeholders.

Here we do still pass along whether or not an offset was specified so that dialects not supporting offsets can generate proper exceptions. In general, dialects will override one or the other of this method and Dialect.getLimitString(String, int, int).

Overrides:

getLimitString in class InterbaseDialect

Parameters:

sql - The query to which to apply the limit.

hasOffset - Is the query requesting an offset?

Returns:

the modified SQL

bindLimitParametersFirst

public boolean bindLimitParametersFirst()

Description copied from class: Dialect

Does the LIMIT clause come at the start of the SELECT statement, rather than at the end?

Overrides:

bindLimitParametersFirst in class InterbaseDialect

Returns:

true if limit parameters should come before other parameters

bindLimitParametersInReverseOrder

public boolean bindLimitParametersInReverseOrder()

Description copied from class: Dialect

ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit. Does this dialect require us to bind the parameters in reverse order?

Overrides:

bindLimitParametersInReverseOrder in class InterbaseDialect

Returns:

true if the correct order is limit, offset
