| ERROR | Invalid reference to variable string |
| CAUSE | A variable was referenced in a way that is inconsistent with its datatype. For example, a scalar variable might have been mistakenly referenced as a record, as follows: DECLARE CURSOR emp_cur IS SELECT empno, ename, sal FROM emp; emp_rec emp_cur%ROWTYPE; my_sal NUMBER(7,2); BEGIN ... total_sal : = total_sal + my_sal.sal; -- invalid ... |
| ACTION | Check the spelling of the variable name. Make sure the variable was declared properly and that the declaration and reference are consistent regarding datatype. |
