Method Detail

• getDropSequenceString

  public String getDropSequenceString​(String sequenceName)

  Description copied from interface: SequenceSupport
  Typically dialects which support sequences can drop a sequence with a single command. This is convenience form ofSequenceSupport.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 overrideSequenceSupport.getDropSequenceStrings(java.lang.String).

  Specified by:

  getDropSequenceString in interface SequenceSupport

  Parameters:

  sequenceName - The name of the sequence

  Returns:

  The sequence drop commands

• getSelectSequenceNextValString

  public 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 fromSequenceSupport.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)                                          throwsMappingException

  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 fromSequenceSupport.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.
