Greetings,

Does anyone know what the purpose of this Ingres function was? It no
longer exists in the current main codeline but it was used in the
past. Thanks

That generates the Val2Str for the RSgvs subsystem.

No, all kidding aside ... In what context is it used? That
might help us understand what it was supposed to do.

Cheers,

RS sounds like Replication Server. I am away from the code this

generic value printer.

What are you doing that needs RSgvs_GenVal2Str?

I'm looking at a file that was deleted in 1998 that uses this
function. I'm trying to decipher what it actually does... Here's the
context:

if (RSgvs_GenVal2Str(col, dk, where_list + STlength(where_list)) !=
OK)
return (RS_INTERNAL_ERR);

This is a file that uses ESQL, and I'm looking at it to get a better
idea how to use parameterized queries in updates. Also wondering if
it's possible to use parameters in a delete query.
Thanks

That is indeed part of an old variant of the Replication Server.
(STlength is an Ingres internal equivalent of strlen(), and it's a
dead giveaway along with the RS_INTERNAL_ERR symbol.) You can assume
that RSgvs_GenVal2Str takes some kind of generic value and makes a
string out of it. Apparently the code is building a WHERE clause.

Delete and update queries both allow parameters in the WHERE clause.
Neither allow them in the FROM clause, as far as I know.
I'm pretty sure that UPDATE allows them in the SET clauses but I'm
not 100% positive about that one.
Are you using parameters in the :host-variable sense, or ?-markers
in a PREPARE statement?
