are used as arguments of the IN predicate. Added a function to check compatibility of row expressions. Made sure that this function to be called for Item_func_in objects by fix_length_and_dec(). mysql-test/r/row.result: Added a test case for bug #27484. mysql-test/t/row.test: Added a test case for bug #27484.
