Yes, when I ping the server is less than 10ms....
Might it be a TDS configuration issue?
Thanks

Thanks for the reply.  I am jost sure I understand what you mean however.
I understand the .conf information.  Your saying make it like so
------------------
# A typical Microsoft SQL Server 2000 configuration
[myserver]
        host = myserver
        port = 1433
        tds version = 4.2
---------------------------


However what are you saying I need to do to the php code? this is what I
have.  Please edit it as you mean. So i understand.

--------------------
<?php

$myServer = "myserver";
$myUser = "myuser";
$myPass = "mypass";
$myDB = "mydb";


$s = mssql_connect("myserver", "$myUser", "$myPass")
or die("Couldn't connect to SQL Server on $myServer");
echo "Connected(1)";

$d = mssql_select_db($myDB, $s)
or die("Couldn't open database $myDB");
echo "Connected(2)";

$query = "SELECT whatever
          FROM there";

$result = mssql_query($query);
$numRows = mssql_num_rows($result);

echo "This a test";

while($row = mssql_fetch_array($result))
{
  echo "<br>$row[0]</br>";
}

?>
----------------


Thanks very much for the interest

Ryan

Hi All!
I work for a company which has several db. I need to extract some data from
a SQL server db and publish it on the web (PHP)
I set up a test environment in order to test the freetds, put I'm
experiencing huge performance problems.
That's what I did.
- A PHP script which extract data from the same table (one on  a SQL Server
system and another one on a mySQL sys), using a SQL server connection will
take more than 10 time the same which extract the same data on the MySql
System
- I tried to run that query on the query analyzer and the result was really
fast...
So the problem I guess is related to the apache web server, but not
completely, because I use the same sever and the same client to run both
scripts...
PLEASE HELP!!!
Thanks!

Hi Andrea,

Did you follow James' suggestions when you last asked about this ?
In the past, performance problems when connecting to SQL Server have proved
to be something to do with the DNS setup in your environment.
Can you "ping" your SQL server, and what is the performance of that ?

Bill

Hi All,

Attached I have the odbclog file and tdsdump file.
Something strange is happening now, I am using freetds 0.62.2 with
OTLV4.
Attached is also the code.

What happens is the select statement does not return the correct id,
instead it seems like it returns some weird long number. ( line 42 - 46
in sample ).

The correct result is returned fine when I use the openlink ODBC driver.
When  I rewrite the C app to Perl it works fine ( using DBI::ODBC ) &
FreeTDS.

I would like to offer assistance if any coding/testing is required,
however I am not familiar with the ODBC-internals..
( That's why I stick to OTL :-)

One more thing: make check failed, I am not sure why but for your
interest I have attached the stderr & stdout logs in makecheckres.tgz

Many thanks
Piet

Ps:
Freddy,
I could not find these lines in 0.62.2 release which you instructed me
to remove in your previous email:

#if !UNIXODBC
        if (stmt->dbc->current_statement != stmt) {
                odbc_errs_add(&stmt->errs, "24000", NULL, NULL);
                ODBC_RETURN(stmt, SQL_ERROR);
        }

        IRD_CHECK;
#endif

from odbc.c (SQLNumResultCols
