Method Detail

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

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.

getSelectSequenceNextValString

public String getSelectSequenceNextValString(String sequenceName)

Description copied from class: Dialect

Generate the select expression fragment that will retreive the next value of a sequence, if sequences are supported.

This differs from Dialect.getSequenceNextValString(String) in that this should return an expression usable within another select statement.

Overrides:

getSelectSequenceNextValString in class Dialect

Parameters:

sequenceName - the name of the sequence

Returns:

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:

getQuerySequencesString in class Dialect

getForUpdateString

public String getForUpdateString()

Description copied from class: Dialect

Does this dialect support the FOR UPDATE syntax?

Overrides:

getForUpdateString in class Dialect

Returns:

Description copied from class: Dialect

Does this dialect support the FOR UPDATE OF syntax?

Overrides:

getForUpdateString in class Dialect

Returns:

boolean

supportsSequences

public boolean supportsSequences()

Description copied from class: Dialect

Does this dialect support sequences?

Overrides:

supportsSequences in class Dialect

Returns:

boolean

supportsLimit

public boolean supportsLimit()

Description copied from class: Dialect

Does this Dialect have some kind of LIMIT syntax?

Overrides:

supportsLimit in class Dialect

getLimitString

public String getLimitString(String sql,
                             boolean hasOffset)

Description copied from class: Dialect

Add a LIMIT clause to the given SQL SELECT

Overrides:

Returns:

true if the correct order is limit, offset

getCurrentTimestampCallString

public String getCurrentTimestampCallString()

isCurrentTimestampSelectStringCallable

public boolean isCurrentTimestampSelectStringCallable()

Overrides:

isCurrentTimestampSelectStringCallable in class Dialect
