Problem with temp table

Problem with temp table

I'm using a temp table in a fucntion to store temporary results, but when calling the same function i've a problem saing that the temporary table already exist. What can be the cause and what is the solution?
I use informix Online edition 11. in an AIX serever.

the function begins with
whenevere error continue
  DROP TABLE temp_table1
  DROP TABLE temp_table2
whenevere error stop

the second cause the problem.
Any Help?

RE: Problem with temp table

I don't mean to elaborate on the obvious, but years ago, I saw a similar problem in Informix stored procedures.  The work around was I had to drop the temp tables before exiting the procedure.

Hi olded,
i've tried to drop the two temp tables before exiting the function with the same portion of code, but this works only the first time and i get the same problem after with also the second table, the first do not cause any problem!
Anyway Thank you.

RE: Problem with temp table


i do this with an exception handler like this:


create procedure mb_1();

drop table tmp_t1;

create temp table tmp_t1 (field1 integer);
create temp table tmp_t1 (field1 integer);

end procedure;

The second create table fires error 958 which results in dropping the temp table.

Hi mberni,
i've used prepared statement when creating temp tables and i've no problem now. I did not tested yet your solution, but i will try it as soon as possible.
Thanks mberni.
