Method Detail

toString

public java.lang.String toString()

Description copied from class: java.lang.Object

Convert this Object to a human-readable String. There are no limits placed on how long this String should be or what it should contain. We suggest you make it as intuitive as possible to be able to place it into System.out.println() 55 and such.

It is typical, but not required, to ensure that this method never completes abruptly with a java.lang.RuntimeException.

This method will be called when performing string concatenation with this object. If the result is null, string concatenation will instead use "null".

The default implementation returns getClass().getName() + "@" + Integer.toHexString(hashCode()).

executeConstantAction

public void executeConstantAction(org.apache.derby.iapi.sql.Activation activation)
                           throws org.apache.derby.iapi.error.StandardException

This is the guts of the Execution-time logic for DROP CONSTRAINT.

dropConstraintAndIndex

protected static void dropConstraintAndIndex(org.apache.derby.iapi.sql.depend.DependencyManager dm,
                                             org.apache.derby.iapi.sql.dictionary.TableDescriptor td,
                                             org.apache.derby.iapi.sql.dictionary.DataDictionary dd,
                                             org.apache.derby.iapi.sql.dictionary.ConstraintDescriptor conDesc,
                                             org.apache.derby.iapi.store.access.TransactionController tc,
                                             org.apache.derby.iapi.sql.Activation activation,
                                             boolean clearDependencies)
