setPreUpdateState

public void setPreUpdateState()

Description copied from interface: UpdatableDBObject

This method is called by the J/R bridging engine after an object has been setup from some tuple retrieved from the database. The method must cause the object to save a copy (/clone) of all the fields that are pertinent to the database. This copy will be retrieved by the J/R bridging engine using the getPreUpdateState() method call, and will subsequently be used by the J/R bridging engine to determine which fields have changed value, and thus to determine which attributes need to be updated in the database.

Specified by:

setPreUpdateState in interface UpdatableDBObject

setRelvarName

public final void setRelvarName(java.lang.String relvarName)

Sets relvarName

Parameters:

relvarName - The relvarName to set.

setRelvarnameFromDB

public void setRelvarnameFromDB(java.lang.String relvarname)

Description copied from interface: TupleconstraintToDBObject

Sets relvarname from the DB

Specified by:

setRelvarnameFromDB in interface TupleconstraintToDBObject

Parameters:

relvarname - The DB value for relvarname

smartUpdateCommand

public DmlAssignmentCommand[] smartUpdateCommand()
                                          throws NoUpdatesException

Gets a "smart" update command that brings the catalog from the state reflected in preUpdateState, to the current state. The "smart" update command consists of :

• optionally (if and only if any changes were applied to the error code or constraintexpression attributes), an update command for the TUPLECONSTRAINT relvar.
• optionally (if and only if any changes were applied to the error code or constraint message text), one of the following to update the CONSTRAINTMESSAGETEXT relvar :
  • a DELETE if the preUpdateState message text was non-null and non-empty, but the new message text is null or the empty string.
  • a INSERT if the preUpdateState message text was null or empty, but the new message text is non-null and a non-empty string.
  • an UPDATE if the preUpdateState message text was non-null and non-empty, and the new message text is non-null and a non-empty string, and it is the case that either the message text or the error code has changed.

Returns:

a "smart" update command that brings the catalog from the state reflected in preUpdateState, to the current state.

Throws:

NoUpdatesException - If there are no differences between the pre-update and the current state
