Requote IN oarameter

Question

I have a procedure that takes a VARCHAR2 IN parameter. When I try to requote this parameter in order to do further processing as I build a update query using this so I've to requote using below statement:
v_property_value := replace(v_property_value,'''','''''');
I get an error when compiling the procedure:
19/4 PLS-00363: expression 'V_PROPERTY_VALUE' cannot be used as an
assignment target
Any ideas please!

Answer 1

note that unless you are passing in into your procedure quoted, the REPLACE will have no effect at all. The incoming parameters are stripped of single quotes.
SQL> CREATE PROCEDURE p (p_val IN VARCHAR2) AS
  2     l_val VARCHAR2(100);
  3  BEGIN
  4     l_val := replace(p_val,'''','''''');
  5     dbms_output.put_line ('Replaced is: '||l_val);
  6  END;
  7  /
Procedure created.
SQL> exec p('Hello');
Replaced is: Hello
PL/SQL procedure successfully completed.
SQL> exec p('''Hello''');
Replaced is: ''Hello''
PL/SQL procedure successfully completed.John
