Constructor Detail

CreateAliasNode

CreateAliasNode(TableName aliasName,
                java.lang.Object targetObject,
                java.lang.String methodName,
                java.lang.Object aliasSpecificInfo,
                char aliasType,
                ContextManager cm)
         throws StandardException

Constructor

Parameters:

aliasName - The name of the alias

targetObject - Target name string or, if aliasType == ALIAS_TYPE_SYNONYM_AS_CHAR, a TableName

methodName - The method name

aliasSpecificInfo - An array of objects, see code for interpretation

cm - The context manager

Throws:

StandardException - Thrown on error

Method Detail

statementToString

java.lang.String statementToString()

Specified by:

statementToString in class StatementNode

bindStatement

public void bindStatement()
                   throws StandardException

Bind this CreateAliasNode. This means doing any static error checking that can be done before actually creating the table. For example, verifying that the column name list does not contain any duplicate column names.

Overrides:

bindStatement in class StatementNode

Throws:

StandardException - Thrown on error

bindAggregate

private void bindAggregate()
                    throws StandardException

Extra logic for binding user-defined aggregate definitions

Throws:

StandardException

illegalAggregate

private StandardException illegalAggregate()

Construct an exception flagging an illegal aggregate name

bindParameterTypes

private void bindParameterTypes(RoutineAliasInfo aliasInfo)
                         throws StandardException

Bind the class names for UDTs

Throws:

StandardException

makeConstantAction

public ConstantAction makeConstantAction()
                                  throws StandardException

Create the Constant information that will drive the guts of Execution.

Overrides:

makeConstantAction in class QueryTreeNode

Throws:

StandardException - Thrown on failure
