public InterbaseDialect()
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
See Also:
SchemaUpdate

getForUpdateString

public String getForUpdateString()
Description copied from class: Dialect
Retrieves the FOR UPDATE syntax specific to this dialect.

Overrides:
getForUpdateString in class Dialect
Returns:
The appropriate FOR UPDATE clause string.

getForUpdateString

public String getForUpdateString(String aliases)
Description copied from class: Dialect
Retrieves the FOR UPDATE OF column_list syntax specific to this dialect, where the given aliases represent the aliases of the columns which are to be write locked.

Overrides:
getForUpdateString in class Dialect
Returns:
The appropriate FOR UPDATE OF column_list clause string.

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:
the modified SQL

bindLimitParametersFirst

public boolean bindLimitParametersFirst()
Description copied from class: Dialect
Does the LIMIT clause come at the start of the SELECT statement, rather than at the end?

Overrides:

Returns:
true if limit parameters should come before other parameters

bindLimitParametersInReverseOrder

public boolean bindLimitParametersInReverseOrder()
Description copied from class: Dialect
Does the LIMIT clause specify arguments in the "reverse" order limit, offset instead of offset, limit?

Overrides:
bindLimitParametersInReverseOrder in class Dialect
Returns:
true if the correct order is limit, offset

getCurrentTimestampCallString

public String getCurrentTimestampCallString()

isCurrentTimestampSelectStringCallable

public boolean isCurrentTimestampSelectStringCallable()
Overrides:
isCurrentTimestampSelectStringCallable in class Dialect
