raw_query is crashing.... - sr-users

8 Jan 2013

Hi,

Since there is no way to limit the result set to 1, I tried to use
raw_query inside msilo module. Everytime it executes, it is crashing. The
same query if I run in mysql shell, it is returning successfully.

Here is the code That I added:

query_len = snprintf(query, 2048, "SELECT *  FROM %.*s  WHERE %.*s='%.*s'
AND %.*s='%.*s' AND %.*s!=%i AND %.*s<%i LIMIT 1;", ms_db_table.len,
ms_db_table.s, sc_uri_touser.len, sc_uri_touser.s, puri.user.len,
puri.user.s, sc_uri_tohost.len, sc_uri_tohost.s, puri.host.len,
puri.host.s, sc_status.len, sc_status.s, 200, sc_status.len, sc_status.s,
MSG_NOTIFY_OFFSET);
        if (query_len < 0) {
                LM_ERR("error in sql snprintf");
                goto error;
        }

        LM_DBG("m_dump_msg: Query=%s\n", query);

        query_str.s = query;
        query_str.len = query_len;
        if (msilo_dbf.raw_query(db_con, &query_str, &db_res) < 0) {
                LM_ERR("Failed to query database. Query = %s\n", query);
                goto error;
        }

The Debug Log at Level 4 shows following:

As you can see something happening to Database connection. Not sure why I
am unable to use raw_query. Normal API query from msilo works just fine.

What am I doing wrong to make it crash?
