Method Details

getSelectSequenceNextValString

public final String getSelectSequenceNextValString(String sequenceName)

Description copied from interface: SequenceSupport

Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement.

This differs from SequenceSupport.getSequenceNextValString(String) in that it must return an expression usable within another statement.

Specified by:

getSelectSequenceNextValString in interface SequenceSupport

Parameters:

sequenceName - the name of the sequence

Returns:

The "next value" fragment.

getSelectSequencePreviousValString

public String getSelectSequencePreviousValString(String sequenceName)
                                          throws MappingException

Description copied from interface: SequenceSupport

Generate the select expression fragment that will retrieve the previous value of a sequence as part of another (typically DML) statement.

This differs from SequenceSupport.getSequencePreviousValString(String) in that it must return an expression usable within another statement.

Specified by:

getSelectSequencePreviousValString in interface SequenceSupport

Parameters:

sequenceName - the name of the sequence

Returns:

The "previous value" fragment.

Throws:

MappingException - If sequences are not supported.
