How to update many tables in PL/SQL

Question

Hi all,
I have to update EMPNIC colum in all the tables using PL/SQL. There are over 700 tables in the database that has the same column name 'EMPNIC'
I create one table called 'UPDATEEMPNIC' According to that table I have to update all the tables.
This is my PL/SQL statement. But in this code its not updating the 'NEWEMPNIC'
PROCEDURE UPDATE_EMP_NIC IS
sql_stmt VARCHAR2(200);
newempnic VARCHAR (20);
empnic VARCHAR (20);
table_name VARCHAR(100);
BEGIN
DECLARE
CURSOR C IS
--I can find all the table names that I have to update using this query.
select table_name from all_tab_cols where table_name like 'TBL%' and column_name like 'EMPNIC';
REC C%ROWTYPE;
TYPE temp_refcur IS REF CURSOR;
temp temp_refcur;
--er temp%ROWTYPE;
type rec_emp is record
newempnic VARCHAR2 (20),
empnic VARCHAR2 (20)
er rec_emp;
     begin
     --for x in cur
          OPEN C ;
          loop
          FETCH C INTO REC;
EXIT WHEN C%NOTFOUND;
open temp for 'SELECT EMPNIC, NEWEMPNIC FROM UPDATEEMPNIC';
loop
          fetch temp into er;
          exit when temp%notfound;
               sql_stmt :='UPDATE '||REC.table_name||' SET EMPNIC ='''||er.NEWEMPNIC||'''WHERE EMPNIC ='''||er.EMPNIC||'''';
               DBMS_OUTPUT.PUT_LINE(sql_stmt);
EXECUTE IMMEDIATE sql_stmt ;
     end loop;
          close temp;
          end loop;
          CLOSE C;
END;
end UPDATE_EMP_NIC;
But I can't find the whats the wrong.
Let me know anyone know to do this.
Thankyou all
