PLS-00321

expression 'string' is inappropriate as the left hand side of an assignment statement

Cause

The expression does not designate a variable that can have a value assigned to it. For example, the function SYSDATE cannot appear on the left hand side of an assignment statement such as SYSDATE := '01-JAN-1990';


Action

Correct the illegal assignment statement.
