| Modifier and Type | Method | Description |
|---|---|---|
(package private) ValueNode |
bindExpression(FromList fromList,
SubqueryList subqueryList,
java.util.List<AggregateNode> aggregates) |
overrides BindOperatorNode.bindExpression because concatenation has
special requirements for parameter binding.

|
(package private) ValueNode |
evaluateConstantExpressions() |
Check if this node always evaluates to the same value.
|
private DataTypeDescriptor |
resolveConcatOperation(DataTypeDescriptor leftType,
DataTypeDescriptor rightType) |
Resolve a concatenation operator
