Thank you, i was experimenting yesterday and i think i got it working
right, but with 0.64+ version.
With versions 0.63+ DB_Cancel should call
tds_process_simple_query to clear pending results, tds_freeall_resulst
does not do this.

Sorry, that was not really right.
"The severity level of an error message provides an indication of the
type of problem that Microsoft(r) SQL Serverï¾™ 2000 has encountered.
Severity level 10 messages are informational and indicate problems
caused by mistakes in the information you have entered. Severity
levels from 11 through 16 are generated by the user, and can be
corrected by the user."
I remember experimenting and finding that it was safe to consider
error levels 1 - 10 "Notice" information and > 10 always indicating a
real "Error" that should be returned to the caller.

Why msg_level > 10, why 10, and not 0?

Vlad,
I installed 0.63 and compiled and installed your module.
It seems to work fine, but has a glitch I ran into as well which is
that it doesn't return error codes when something went wrong with the
query itself. For example, with my hack I get this
SQL:
SELECT cast('foo' as int)
Results:
error: Database operation "exec" failed (exception NSDB, "Syntax
error converting the varchar value 'foo' to a column of data type
int.")
Rows affected: -1
With your version I get
SQL:
SELECT cast('foo' as int)
Results:
Rows affected: -1
While the log indicates
[25/May/2005:12:46:20][17746.1090534320][-conn:server1::0] Notice:
Db_Msg_Handler(fundware): Syntax error converting the varchar value
'foo' to a column of data type int.
This has to do with a fundamental change in error handling where
non-network communication errors are not errors to freetds anymore.
They are simply passed back to the application for it to handle.
Here is my hack which seems to work but may be terribly wrong for other reasons.
int
Ns_FreeTDS_Msg_Handler(TDSCONTEXT *ctx, TDSSOCKET *tds, TDSMESSAGE *msg)
{
Ns_DbHandle *handle = (Ns_DbHandle *) tds->parent;
Ns_Log(Notice, "nsfreetds: Ns_FreeTDS_Msg_Handler(%s): %s",
handle->datasource, msg->message);
// Begin hack
if ( msg->msg_level > 10 )
Ns_DbSetException(handle, "NSDB", msg->message);
// End hack
return 0;
}

Try newest FreeTDS 0.63 with my modified nsfreetds driver.
http://cvs.sourceforge.net/viewcvs.py/naviserver/modules/nsfreetds/
It does not support interfaces anymore, use freetds.conf and describe
datasource there.

Hi everyone,
I'm having trouble getting nsfreetds running, and I'm hoping that
someone can spot what I'm doing wrong. I noticed that several people on
the list have gotten it working at various times, so I assume it's just me.
I'm using nsfreetds 0.4 with FreeTDS 0.6.1.2 (newer versions of FreeTDS
won't compile on this server) and AOLserver 4.0.10
running on Mandrake 10.0. I'm trying to connect to Microsoft SQLServer
Desktop Engine 2000 SP4 running on my Windows XP workstation. I'm
getting the "could not allocate a handle from database pool "pool4""
error page when I hit my site.
I can connect to the SQL server with tsql, though it doesn't give me any
output when I type in SQL commands. Not sure what that's about.
Authentication works fine, and it rejects me if I don't give it the
correct credentials. Anyway, I'm assuming that it works for now and am
trying to get nsfreetds working.
The relevent sections from my config.tcl (copied from the nsfreetds FAQ)
are as follows:
ns_section ns/db/drivers
ns_param freetds ${bindir}/nsfreetds.so
ns_section ns/db/pools
ns_param pool4 "FreeTDS Pool"
ns_section ns/db/pool/pool4
ns_param maxidle 1000000000
ns_param maxopen 1000000000
ns_param connections 5
ns_param verbose $debug
ns_param extendedtableinfo true
ns_param logsqlerrors $debug
ns_param driver freetds
ns_param datasource fooserver [also tried fooserver:bardb]
ns_param user sa
ns_param password bazpassword
ns_section ns/server/${server}/db
ns_param pools "*"
ns_param defaultpool pool4
I have the SYBASE environment variable set to /usr/local/etc, which is
where my interfaces file lives. It looks like this:
fooserver
query tcp 8.0 192.168.42.107 1433 [I have tried protocol version
4.2 instead of 8.0 and it makes no difference]
Hopefully someone can point me in the right direction. I've been
banging my head against it for a few days now and I'm afraid that I'm
missing something obvious but am at a loss as to what it might be.
Thanks in advance,
-Cory
