MS SQL Server, varchar only returns 255 chars
I'm running a SQL Server with PHP (this host doesn't have mySQL) and I'm running into a problem with the varchar field.
I've got a table with varchar(5000) (because SQL Server lets you do that ) because I want to be able to select DISTINCT resutls.
SQL Server does not allow distinct to be used on a TEXT field, thus the varchar(5000).
Now, when I query the results using mssql_fetch_assoc(), I only get the first 255 chars of that field.
Is there any way to get the entire result back or is there a way in SQL server to select unique records from a TEXT field?

selecting distinct on a fieldset of that size would effectively kill your DB anyway ... better off when you add the data to the DB do a checksum ,eg
<?php $check = MD5($text);?>
and stick that in a seperate field for selecting distinct, your DB will love you for it I promise
MVC is the current buzz in web application architectures. It comes from event-driven desktop application design and doesn't fit into web application design very well. But luckily nobody really knows what MVC means, so we can call our presentation layer separation mechanism MVC and move on. (Rasmus Lerdorf)
