Method Detail

supportsSequences

public boolean supportsSequences()
Description copied from class: Dialect
Does this dialect support sequences?

Overrides:
supportsSequences in class Dialect
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 class Dialect
Returns:
True if such "pooled" sequences are supported; false otherwise.
See Also:
Dialect.getCreateSequenceStrings(String, int, int), Dialect.getCreateSequenceString(String, int, int)

getCreateSequenceString

public String getCreateSequenceString(String sequenceName)
Description copied from class: Dialect
Typically dialects which support sequences can create a sequence with a single command. This is convenience form of Dialect.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 override Dialect.getCreateSequenceStrings(java.lang.String).

Overrides:
getCreateSequenceString in class Dialect
Parameters:
sequenceName - The name of the sequence
Returns:
The sequence creation command

getDropSequenceString

public String getDropSequenceString(String sequenceName)
Description copied from class: Dialect
Typically dialects which support sequences can drop a sequence with a single command. This is convenience form of Dialect.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 override Dialect.getDropSequenceStrings(java.lang.String).

Overrides:
getDropSequenceString in class Dialect
Parameters:
sequenceName - The name of the sequence
Returns:
The sequence drop commands

getSelectSequenceNextValString

public String getSelectSequenceNextValString(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 from Dialect.getSequenceNextValString(String) in that this should return an expression usable within another statement.

Overrides:
getSelectSequenceNextValString in class Dialect
Parameters:
sequenceName - the name of the sequence
Returns:
The "nextval" fragment.

getSequenceNextValString

public String getSequenceNextValString(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 class Dialect
Parameters:
sequenceName - the name of the sequence
Returns:
String The "nextval" select string.

getQuerySequencesString

public String getQuerySequencesString()
Description copied from class: Dialect
Get the select command used retrieve the names of all sequences.

Overrides:
getQuerySequencesString in class Dialect
Returns:
The select command; or null if sequences are not supported.
See Also:
SchemaUpdate

public boolean supportsIdentityColumns()
Description copied from class: Dialect
Does this dialect support identity column key generation?

Overrides:
supportsIdentityColumns in class Dialect
Returns:
True if IDENTITY columns are supported; false otherwise.

getIdentitySelectString

Returns:
The appropriate select command

getIdentityColumnString

public String getIdentityColumnString()
Description copied from class: Dialect
