Method Details

getOperandCountRange

public SqlOperandCountRange getOperandCountRange()

Description copied from class: SqlOperator

Returns a constraint on the number of operands expected by this operator. Subclasses may override this method; when they don't, the range is derived from the SqlOperandTypeChecker associated with this operator.

Overrides:

getOperandCountRange in class SqlOperator

Returns:

acceptable range

checkOperandCount

protected void checkOperandCount(SqlValidator validator,
 @Nullable SqlOperandTypeChecker argType,
 SqlCall call)

Overrides:

checkOperandCount in class SqlOperator
