Hello.  I am trying to use freetds in conjunction with php and MS SQL
Server 7.  I have posted a couple quiestions to the php mailing list, but
have hit a wall there.

I have included the reply I recieved to the first post and my second post
below.  I believe I have a configuration problem unrelated to php or the
database because it seems freetds always wants to connect to
255.255.255.255 port 0 and that is not what I had in the interfaces file.

Any help would be greatly appreciated.  I am sooo close and I really hope
this solution will perform better than our existing one which is using an
ODBC bridge.

Thanks!

Posteded to the PHP General Mailing List...

Thanks for you build record, that helped greatly,  I think my main problem
was using 0.52 instead of 0.51.

No more seg faults now when I try to run my script, but I am still not
getting a connection to the database, and I think the problem may be the
fact the freetds is not finding any configuration information.  Here is
the php script I am running:

<?
putenv("TDSDUMP=/usr/local/apache_test/logs/tds.log");

$nDBConn = mssql_connect("mmg", "username", "passwd");
echo "ConnectID: $nDBConn<br>\n";

$nStmt = mssql_query("select * from david_test", $nDBConn);

while ($aRow = mssql_fetch_array($nStmt)) {
        echo $aRow["Name"];
        echo "<p>\n";
}

mssql_close($nDBConn);
echo "hello dave";
?>

And when this runs there are connection errors, but if I look in the
TDSDUMP file I specified at the beginning of the script I see this (which
is not the ip or port I specified in my interfaces file): 2001-10-17
09:39:24 Connecting addr 255.255.255.255 port 0

Along with these errors in my Apache error log file:
connect: Network is unreachable
DB-Library: Login incorrect.

Here is my interfaces file, located at /usr/local/freetds
mmg
        query tcp tds4.2 ip.of.db.server 1433

And last, here is the value of the SYBASE env variable:
[root /root]# echo $SYBASE
/usr/local/freetds

Did you or anyone else run in to this problem?  I looked in the config
file to see if there was a path you could specify for the interfaces file
but found only an alternate method of configuring freetds, so I renamed it
to zzz_freetds.conf and still get the error message saying it is
connecting to 255.255.255.255.

Thanks again in advance for any help.

We have that working reliably with the exception that I have used TDS 
protocol version 4.2 rather than 7.0 because I had read that this was a 
little less well developed, and 4.2 gives you all you need in any case.

We're using slightly different components:  Apache 1.3.20, PHP 4.0.6,
FreeTDS
0.51 running on a Slackware 8.0 base (Linux kernel 2.2.19 with glibc
2.2.3)

I've attached an HTML file of our build record for this.

The other thing to note is that this approach allows you to use PHP's
mssql_
calls, but only those that have direct sybase_ equivalents.  So make sure
you
check out which calls are common to both sets of functions and don't try 
calls that only exist in the mssql_ function list.
