I can confirm that adding 'WITH (NOLOCK)' to apparently read-only PHP
applications using FreeTDS does indeed reduce the locking delays
experienced by updating stored procedures used by other users.

It's nothing to do with FreeTDS or PHP, it's just the way the server
works.

I didn't know!  I guess many of us have entered the SQL arena with
insufficient knowledge.

Has anyone taken the sequence above and made a generalised PHP script
for it?  contention.php
