Method Detail

dropConstraints

public boolean dropConstraints()

Description copied from class: Dialect

Do we need to drop constraints before dropping tables in this dialect?

Overrides:

dropConstraints in class Dialect

Returns:

boolean

qualifyIndexName

public boolean qualifyIndexName()

Description copied from class: Dialect

Do we need to qualify index names with the schema name?

Overrides:

qualifyIndexName in class Dialect

Returns:

boolean

supportsUnique

public boolean supportsUnique()

Description copied from class: Dialect

Does this dialect support the UNIQUE column syntax?

Overrides:

supportsUnique in class Dialect

Returns:

boolean

supportsUniqueConstraintInCreateAlterTable

public boolean supportsUniqueConstraintInCreateAlterTable()

Description copied from class: Dialect

Does this dialect support adding Unique constraints via create and alter table ?

Overrides:

supportsUniqueConstraintInCreateAlterTable in class Dialect

Returns:

boolean

getAddColumnString

public String getAddColumnString()

Description copied from class: Dialect

The syntax used to add a column to a table (optional).

Overrides:

getAddColumnString in class Dialect

supportsSequences

public boolean supportsSequences()

Description copied from class: Dialect

Does this dialect support sequences?

Overrides:

supportsSequences in class Dialect

getSelectSequenceNextValString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getSequenceNextValString

public String getSequenceNextValString(String sequenceName)

Description copied from class: Dialect

Generate the appropriate select statement to to retreive the next value of a sequence, if sequences are supported.

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.

getCreateSequenceString

public String getCreateSequenceString(String sequenceName)

Description copied from class: Dialect

The syntax used to create a sequence, if sequences are supported.

Overrides:

getCreateSequenceString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getDropSequenceString

public String getDropSequenceString(String sequenceName)

Description copied from class: Dialect

The syntax used to drop a sequence, if sequences are supported.

Overrides:

getDropSequenceString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

String

getQuerySequencesString

public String getQuerySequencesString()

Description copied from class: Dialect

A query used to find all sequences

Overrides:
