Hi, sqlops module documentation doesn't say what the function
sql_query returns in case of DB failure. I'll do my tests but if
somebody knows I would like to know the expected return code.
Thanks a lot.

Hi Iñaki,
it returns this values:
* 1 on succes
* 2 on success, but no result after query
* -1 on failure
modules_k/sqlops/sql_api.c
197:int sql_do_query(struct sip_msg *msg, sql_con_t *con, pv_elem_t *query,
Cheers,
Henning

Let me another question. Let's suppose the following case:
-------------------
sql_query("con1", "SELECT field1 FROM table1", "res");
sql_query("con1", "SELECT field1, field2, field3 FROM table2",
"res");
sql_result_free("res");
------------------
Is it safe? This is, can I perform a second query storing the result
in same "res" structure without freeing before? would it leak? would
be overlap in the "res" structure after the second query?
Thanks a lot.

yes, i think it would be useful.

AFAIK this was discussed to some extend earlier - if i remember correctly the
second sql_query will free the first result set before executing its SQL. So
neiter the queries nor the result sets should overlap. If you looking for
something like a cfg script DB "fetch_result", then i think this is currently
not available. But of course this could be added.
