bindStatement
Description copied from class:StatementNode
Perform the binding operation statement. 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 bindStatement() method does nothing. Each StatementNode type that can appear at the top of a tree can override this method with its own bindStatement() method that does "something".- Overrides:
bindStatement
in classStatementNode
- Throws:
StandardException
- Thrown on error
-
toString
Convert this object to a String. See comments in QueryTreeNode.java for how this should be done for tree printing.- Overrides:
toString
in classDDLStatementNode
- Returns:
- This object as a String
-
statementToString
- Specified by:
statementToString
in classStatementNode
-
makeConstantAction
Create the Constant information that will drive the guts of Execution.- Overrides:
makeConstantAction
in classQueryTreeNode
- Throws:
StandardException
- Thrown on failure
