Method Details
-
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
String statementToString()- Specified by:
statementToString
in classStatementNode
-
bindStatement
Bind this LockTableNode. This means looking up the table, verifying it exists and getting the heap conglomerate number.- Overrides:
bindStatement
in classStatementNode
- Throws:
StandardException
- Thrown on error
-
referencesSessionSchema
Return true if the node references SESSION schema tables (temporary or permanent)- Overrides:
referencesSessionSchema
in classQueryTreeNode
- Returns:
- true if references SESSION schema tables, else false
- Throws:
StandardException
- Thrown on error
-
makeConstantAction
Create the Constant information that will drive the guts of Execution.- Overrides:
makeConstantAction
in classQueryTreeNode
- Throws:
StandardException
- Thrown on failure
