Method Detail

supportsSequences
public boolean supportsSequences()
Description copied from class:Dialect
Does this dialect support sequences?- Overrides:
supportsSequences
in classDialect
- Returns:
- True if sequences supported; false otherwise.
-
supportsPooledSequences
public boolean supportsPooledSequences()
Description copied from class:Dialect
Does this dialect support "pooled" sequences. Not aware of a better name for this. Essentially can we specify the initial and increment values?- Overrides:
supportsPooledSequences
in classDialect
- Returns:
- True if such "pooled" sequences are supported; false otherwise.

getCreateSequenceString
public java.lang.String getCreateSequenceString(java.lang.String sequenceName)
Description copied from class:Dialect
Typically dialects which support sequences can create a sequence with a single command. This is convenience form ofDialect.getCreateSequenceStrings(java.lang.String)
to help facilitate that. Dialects which support sequences and can create a sequence in a single command need *only* override this method. Dialects which support sequences but require multiple commands to create a sequence should instead overrideDialect.getCreateSequenceStrings(java.lang.String)
.- Overrides:
getCreateSequenceString
in classDialect
- Parameters:
sequenceName
- The name of the sequence- Returns:
- The sequence creation command
-
getDropSequenceString
public java.lang.String getDropSequenceString(java.lang.String sequenceName)
Description copied from class:Dialect
Typically dialects which support sequences can drop a sequence with a single command. This is convenience form ofDialect.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 overrideDialect.getDropSequenceStrings(java.lang.String)
.- Overrides:
getDropSequenceString
in classDialect
- Parameters:
sequenceName
- The name of the sequence- Returns:
- The sequence drop commands
-
getSequenceNextValString
public java.lang.String getSequenceNextValString(java.lang.String sequenceName)
Description copied from class:Dialect
Generate the appropriate select statement to to retrieve the next value of a sequence. This should be a "stand alone" select statement.- Overrides:
getSequenceNextValString
in classDialect
- Parameters:
sequenceName
- the name of the sequence- Returns:
- String The "nextval" select string.
-
getSelectSequenceNextValString
public java.lang.String getSelectSequenceNextValString(java.lang.String sequenceName)
Description copied from class:Dialect
Generate the select expression fragment that will retrieve the next value of a sequence as part of another (typically DML) statement. This differs fromDialect.getSequenceNextValString(String)
in that this should return an expression usable within another statement.- Overrides:
getSelectSequenceNextValString
in classDialect
- Parameters:
sequenceName
- the name of the sequence- Returns:
- The "nextval" fragment.
-
getQuerySequencesString
public java.lang.String getQuerySequencesString()
Description copied from class:Dialect
Get the select command used retrieve the names of all sequences.- Overrides:
getQuerySequencesString
in classDialect
- Returns:
- The select command; or null if sequences are not supported.
- See Also:
SchemaUpdate
-
getWriteLockString
public java.lang.String getWriteLockString(int timeout)
Description copied from class:Dialect
Get the string to append to SELECT statements to acquire WRITE locks for this dialect. Location of the of the returned string is treated the same as getForUpdateString.- Overrides:
getWriteLockString
in classMySQLDialect
- Parameters:
timeout
- in milliseconds, -1 for indefinite wait and 0 for no wait.- Returns:
- The appropriate LOCK clause string.
-
getForUpdateNowaitString
public java.lang.String getForUpdateNowaitString()
Description copied from class:Dialect
Retrieves the FOR UPDATE NOWAIT syntax specific to this dialect.- Overrides:
getForUpdateNowaitString
in classDialect
- Returns:
- The appropriate FOR UPDATE NOWAIT clause string.
-
getForUpdateNowaitString
public java.lang.String getForUpdateNowaitString(java.lang.String aliases)
Description copied from class:Dialect
Get the FOR UPDATE OF column_list NOWAIT fragment appropriate for this dialect given the aliases of the columns to be write locked.- Overrides:
getForUpdateNowaitString
in classDialect
- Parameters:
aliases
- The columns to be write locked.- Returns:
- The appropriate FOR UPDATE OF colunm_list NOWAIT clause string.
