public Oracle9Dialect()
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

Overrides:
getLimitString in class Dialect
Returns:
the modified SQL

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:
