AlterConstraintConstantAction (Apache Derby V10.14 Internals)

java.lang.Object
- org.apache.derby.impl.sql.execute.DDLConstantAction
- - org.apache.derby.impl.sql.execute.DDLSingleTableConstantAction
  - - org.apache.derby.impl.sql.execute.ConstraintConstantAction
    - - org.apache.derby.impl.sql.execute.AlterConstraintConstantAction

All Implemented Interfaces:

ConstantAction
```
public class AlterConstraintConstantAction
extends ConstraintConstantAction
```
This class describes actions that are ALWAYS performed for a alter constraint at Execution time.

    Constructor.
    
    Parameters:
    
    constraintName - The constraint name.
    
    constraintSchemaName - The schema that constraint lives in.
    
    characteristics - The (presumably) altered enforcement characteristics.
    
    tableName - Table name.
