Nicolas,

Maybe you don't want to use native scripting, but look on KEMI?

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.

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 ?
