public DropSchemaNode()
init
public void init(java.lang.Object schemaName,
java.lang.Object dropBehavior)
throws StandardException
- Initializer for a DropSchemaNode
- Overrides:
init
in class QueryTreeNode
- Parameters:
schemaName
- The name of the object being droppeddropBehavior
- Drop behavior (RESTRICT | CASCADE)
- Throws:
StandardException
- Thrown on error
bind
public QueryTreeNode bind()
throws StandardException
- Description copied from class:
QueryTreeNode
- Perform the binding operation on a query tree. Binding consists of
permissions checking, view resolution, datatype resolution, and
creation of a dependency list (for determining whether a tree or
plan is still up to date).
This bind() method does nothing. Each node type that can appear
at the top of a tree can override this method with its own bind()
method that does "something".
- Overrides:
bind
in class QueryTreeNode
- Returns:
- The bound query tree
- Throws:
StandardException
- Thrown on error
toString
public java.lang.String toString()
- Convert this object to a String. See comments in QueryTreeNode.java
for how this should be done for tree printing.
- Overrides:
toString
in class DDLStatementNode
- Returns:
- This object as a String
statementToString
public java.lang.String statementToString()
- Specified by:
statementToString
in class StatementNode
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
