PLS-00231: function string may not be used in SQL

Cause: A proscribed function was used in a SQL statement. Certain functions such as SQLCODE and SQLERRM can be used only in procedural statements.

Action: Remove the function call from the SQL statement. Or, replace the function call with a local variable. For example, the following statement is illegal: INSERT INTO errors VALUES (SQLCODE, SQLERRM); However, you can assign the values of SQLCODE and SQLERRM to local variables, then use the variables in the SQL statement, as follows: err_num := SQLCODE; err_msg := SQLERRM; INSERT INTO errors VALUES (err_num, err_msg);
