DB2Dictionary

public DB2Dictionary()

Method Detail

getPlatform

public java.lang.String getPlatform()

Description copied from class: DBDictionary

Return the database platform for this dictionary.

Overrides:

getPlatform in class DBDictionary

supportsSelectForUpdate

public boolean supportsSelectForUpdate()

Description copied from class: DBDictionary

Whether locking on queries is supported; returns the metadata's reported value by default.

Overrides:

supportsSelectForUpdate in class DBDictionary

supportsForeignKeyDeleteAction

public boolean supportsForeignKeyDeleteAction(int action)

Description copied from class: DBDictionary

Return true if the database supports the given foreign key delete action. Returns true for all actions except ForeignKey.ACTION_NONE by default.

Overrides:

supportsForeignKeyDeleteAction in class DBDictionary

supportsDeferredConstraints

public boolean supportsDeferredConstraints()

Description copied from class: DBDictionary

Return true if the database supports deferred constraints. Returns true by default.

Overrides:

supportsDeferredConstraints in class DBDictionary

getPreferredType

public int getPreferredType(int type)

Description copied from class: DBDictionary

Return the preferred Types type for the given one. Returns the given type by default.

Overrides:

getPreferredType in class DBDictionary

getDropColumnSQL

public java.lang.String[] getDropColumnSQL(com.solarmetric.rd.kodo.impl.jdbc.schema.Column col)

Description copied from class: DBDictionary

Return a series of SQL statements to drop the given column from its table. Return an empty array if operation not supported. The DBMetaData is checked for support automatically. Returns ALTER TABLE <table name> DROP COLUMN <col name> by default.

Overrides:

getDropColumnSQL in class DBDictionary

wrapConnection

public java.sql.Connection wrapConnection(java.sql.Connection conn)

Description copied from class: DBDictionary

Wrap the given connection if needed. Some databases require special handling for JDBC bugs. If this method is overridden, it should wrap the connection returned by super.wrapConnection rather than the original connection argument. By default, the connection is wrapped in a special connection type that always uses scrollable result sets (but only if the database supports it and the configuration's DefaultFetchThreshold is not -1).

Overrides:

wrapConnection in class DBDictionary
