Method Summary

Modifier and TypeMethod and Description
public String
getDropSequenceString(String
The name of the sequence
sequenceName)

Overrides default org.hibernate.dialect.sequence.SequenceSupport.getDropSequenceString.

Typically dialects which support sequences can drop a sequence with a single command.
public String
getSelectSequenceNextValString(String
the name of the sequence
sequenceName)

Implements org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString.

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

Overrides default org.hibernate.dialect.sequence.SequenceSupport.getSelectSequencePreviousValString.

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

Overrides default org.hibernate.dialect.sequence.SequenceSupport.getSequenceNextValString.

Generate the appropriate select statement to to retrieve the next value of a sequence.
public String
getSequencePreviousValString(String
the name of the sequence
sequenceName)

Overrides default org.hibernate.dialect.sequence.SequenceSupport.getSequencePreviousValString.

Generate the appropriate select statement to to retrieve the previous value of a sequence.

public String getDropSequenceString(String sequenceName)

Overrides default org.hibernate.dialect.sequence.SequenceSupport.getDropSequenceString.

Doc from org.hibernate.dialect.sequence.SequenceSupport.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

public String getSelectSequenceNextValString(String sequenceName)

Implements org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString.

Doc from org.hibernate.dialect.sequence.SequenceSupport.getSelectSequenceNextValString.

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

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

Parameters
sequenceName:String

the name of the sequence

Returns:String

The "next value" fragment.

Parameters

Returns:String

The "previous value" fragment.
