Re: [SR-Users] PostgreSQL - module sqlops - working with prepared statements ?

Hello, Trying again, in case this got unnoticed the first time. I hope that by doing so I’m not breaching the rules of the mailing list. If nobody answers, then I’ll conclude that nobody knows about that, and shall not insist anymore. :) Regards, Nicolas. *De :*sr-users <sr-users-bounces(a)lists.kamailio.org> *De la part de* Chaigneau, Nicolas *Envoyé :* vendredi 8 avril 2022 17:01 *À :* sr-users(a)lists.kamailio.org *Objet :* [SR-Users] PostgreSQL - module sqlops - working with prepared statements ? Hello, I’m using sql_xquery from sqlops module to execute requests on a PostgreSQL database. This work fine. Now, for performance reasons, I would like to use prepared statements. I’m wondering if this is possible using sql_xquery. I’ve looked at the code and documentation, it seems it is not supported. Can you confirm ? If not possible with sql_xquery, is it possible with another existing function ? In the code, I’ve searched for « PQprepare » / « PQexecPrepared ». These can be found only in « modules/db_postgres/pg_cmd.c », in function « pg_cmd_exec » which is exported from « modules/db_postgres/pg_mod.c » (see below). I have no idea how to use these though… :/ Any ideas ? /* * Postgres module interface */ static cmd_export_t cmds[] = { {"db_ctx", (cmd_function)NULL, 0, 0, 0, 0}, {"db_con", (cmd_function)pg_con, 0, 0, 0, 0}, {"db_uri", (cmd_function)pg_uri, 0, 0, 0, 0}, {"db_cmd", (cmd_function)pg_cmd, 0, 0, 0, 0}, {"db_put", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_del", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_get", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_upd", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_sql", (cmd_function)pg_cmd_exec, 0, 0, 0, 0}, {"db_res", (cmd_function)pg_res, 0, 0, 0, 0}, {"db_fld", (cmd_function)pg_fld, 0, 0, 0, 0}, {"db_first", (cmd_function)pg_cmd_first, 0, 0, 0, 0}, {"db_next", (cmd_function)pg_cmd_next, 0, 0, 0, 0}, {"db_setopt", (cmd_function)pg_setopt, 0, 0, 0, 0}, {"db_getopt", (cmd_function)pg_getopt, 0, 0, 0, 0}, {"db_bind_api", (cmd_function)db_postgres_bind_api, 0, 0, 0, 0},        {0, 0, 0, 0, 0, 0} }; Regards, Nicolas.
