Hi Alex,

No problems, I probably wasn't very clear. I have seen the report
Microsoft, however it isn't related to the issue at hand. DB Artisan is
working just fine and reporting the correct count of rows impacted.

For me there is no doubt in my mind that it is an issue with the dbcount
procedure.

Hi Cedric,

"Asche über mein Haupt" -
I should have been quit if I don't know what DBCOUNT(dbproc) is.
MS says, that something changes with SET ROWCOUNT, but for SQL Server 2005
MS said the same.
http://msdn.microsoft.com/en-us/library/ms188774.aspx
http://jmkehayias.blogspot.com/2008/12/set-rowcount-functionality-changes.html


Maybe now they really changed something in SQL Server 2008.
Unfortunately I have no v2008 to test.

Mfg Alexander

Hi Alex,

I am reporting a bug in the dblib.c because the function dbcount(DBPROCESS
* dbproc) returns -1 instead of returning the number of rows affected. So
this is not a MS Sql issue but a problem in FreeTDS/dblib

The problem can be seen at the bsqldb.c function with this code:

            /*
             * Get row count, if available.
             */
            if (!options.fquiet) {
                  if (DBCOUNT(dbproc) > -1) {
                        fprintf(options.output, "(%d rows affected)\n",
DBCOUNT(dbproc));
                  }
                  // Removed the following code in order to replicate
SYBASE ISQL behaviour.
                  //else fprintf(stderr, "@@rowcount not available\n");
            }

I commented out the fprintf in my code to replicate the behaviour of ISQL
from Sybase, however the statement is incorrect in the sense that the value
of @@rowcount is available and set correctly (I checked this by doing
select @@ROWCOUNT in bsqldb and it correctly returned 10).

Hopes this clarifies,

Cedric

Hi,
this is a FreeTDS-mailing list, not a SQLServer-forum :-)

But: "set rowcount nn" is something completly different then "@@ROWCOUNT".
"set rowcount 10" limits the number of returned rows when doing a SELECT.
If a table has 20 rows then only 10 rows will be returned.
"@@ROWCOUNT" is set by SQLServer and contains the number of affected rows,
i.e. with UPDATE
Maybe look at MS doc to see
Mfg Alexander

Hi,

Me again, anybody have any clues? When I execute select @@ROWCOUNT I get
the correct count that is to say. Why would the rowcount not be available ?

Hi guys,

I have come across an interesting behaviour with SQL Server 2008, when you
use the instruction: "set rowcount nn" such as "set rowcount 10" then
DBCOUNT(dbproc) returns -1.

Anyone have any ideas???

Thanks,

Cedric
