inferReturnType
Description copied from class:SqlOperator
Infers the return type of an invocation of this operator; only called after the number and types of operands have already been validated. Subclasses must either override this method or supply an instance ofSqlReturnTypeInference
to the constructor.- Overrides:
inferReturnType
in classSqlOperator
- Parameters:
opBinding
- description of invocation (not necessarily aSqlCall
)- Returns:
- inferred return type
