public boolean
bindLimitParametersFirst()

Overrides org.hibernate.dialect.InterbaseDialect.bindLimitParametersFirst.

Does the LIMIT clause come at the start of the SELECT statement, rather than at the end?
public boolean
bindLimitParametersInReverseOrder()

Overrides org.hibernate.dialect.InterbaseDialect.bindLimitParametersInReverseOrder.

ANSI SQL defines the LIMIT clause to be in the form LIMIT offset, limit.
public String
getDropSequenceString(String
The name of the sequence

Overrides org.hibernate.dialect.InterbaseDialect.getDropSequenceString.

Typically dialects which support sequences can drop a sequence with a single command.

getLimitString(String
The query to which to apply the limit.

Is the query requesting an offset?

public boolean bindLimitParametersFirst()

Overrides org.hibernate.dialect.InterbaseDialect.bindLimitParametersFirst.

Doc from org.hibernate.dialect.Dialect.bindLimitParametersFirst.

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

Returns:boolean

true if limit parameters should come before other parameters

bindLimitParametersInReverseOrderback to summary
public boolean bindLimitParametersInReverseOrder()

Overrides org.hibernate.dialect.InterbaseDialect.bindLimitParametersInReverseOrder.

Doc from org.hibernate.dialect.Dialect.bindLimitParametersInReverseOrder.

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?

Returns:boolean

true if the correct order is limit, offset

getDropSequenceStringback to summary
public String getDropSequenceString(String sequenceName)

Overrides org.hibernate.dialect.InterbaseDialect.getDropSequenceString.

Doc from org.hibernate.dialect.Dialect.getDropSequenceString.

Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of getDropSequenceStrings 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 getDropSequenceStrings.

Parameters
sequenceName:String

The name of the sequence

Returns:String

The sequence drop commands

getLimitStringback to summary
public String getLimitString(String sql, boolean hasOffset)

Overrides org.hibernate.dialect.InterbaseDialect.getLimitString.

Doc from org.hibernate.dialect.Dialect.getLimitString.

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 getLimitString(String, int, int).

Parameters
sql:String

The query to which to apply the limit.

hasOffset:boolean

Is the query requesting an offset?

Returns:String

the modified SQL
