SQL & PL/SQL

hi, guys:

I have a question about exception syntax, I want to record the number of rows of multiple tables, but if a table does not exist, my program should be able to continue loop.

create or replace procedure check_rows as


   cursor t1 is select table_name from all_csv
             where table_built='Y'
             and table_name is not null;

  match_count1 INTEGER;
  
begin

   for n in t1 loop
   
      dbms_output.put_line(n.table_name);
      EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || n.table_name INTO match_count1 ;

      
      update all_csv
      set total_rows=match_count1
      where table_name=n.table_name;
      
      exception when table_does_not_exist then null end;  

   end loop;
   
   commit;

end;

I go ta syntax error as :


PLS-00103: Encountered the symbol "EXCEPTION" when expecting one
of the following:
begin case declare end exit for goto if loop mod null pragma
raise return select update while with <an identifier>
<a double-quoted delimited-identifier> <a bind variable> <<
close current delete fetch lock insert open rollback
savepoint set sql execute commit forall merge pipe

Anyone could give me a hint?

Thanks a lot!
