- org.apache.derby.impl.sql.execute.DDLConstantAction
- - org.apache.derby.impl.sql.execute.CreateAliasConstantAction

All Implemented Interfaces:

ConstantAction
```
class CreateAliasConstantAction
extends DDLConstantAction
```
This class performs actions that are ALWAYS performed for a CREATE FUNCTION, PROCEDURE or SYNONYM Statement at execution time. These SQL objects are stored in the SYS.SYSALIASES table and represented as AliasDescriptors.

```
    Make the ConstantAction for a CREATE alias statement.
    
    Parameters:
    
    aliasName - Name of alias.
    
    schemaName - Name of alias's schema.
    
    javaClassName - Name of java class.
    
    aliasInfo - AliasInfo
    
    aliasType - The type of the alias

    This is the guts of the Execution-time logic for CREATE FUNCTION, PROCEDURE, SYNONYM, and TYPE.
    A function, procedure, or udt is represented as:
    
    AliasDescriptor
    Routine dependencies are created as:
    
    None
    
    A synonym is represented as:
    
    AliasDescriptor
    TableDescriptor
    Synonym dependencies are created as:
    
    None
    In both cases a SchemaDescriptor will be created if needed. No dependency is created on the SchemaDescriptor.
    Parameters:
    
    activation - The execution environment for this constant action.
    
    Throws:
    
    StandardException - Thrown on failure
    
    See Also:
    
    ConstantAction.executeConstantAction(org.apache.derby.iapi.sql.Activation), AliasDescriptor, TableDescriptor, SchemaDescriptor
  - vetRoutine
