RE: PHP and MS-SQL

Hi,

It is true that FreeTDS works with MS SQL Server, but I think you need a bit more info:

Sybase and MS SQL Server used to be the same product back when 4.x was released. Then Microsoft released 6.0 including a set of C libraries and everything was fine. Microsoft has not released new versions of the C libraries but they have added a lot of new features to the server with version 6.5, 7.0 and 2000. These features are not available from the C libraries so no matter if you are using the native MSSQL extension for Win32 or you use the Sybase extension with FreeTDS you are limited to the features available in version 6.0 of MS SQL Server.

These limitations include char and varchar columns with maximum 255 bytes. No support for nchar, nvarchar or ntext and other types as well. If you can design your tables without using the new features you should be able to make it work.

One of the big differences in the SQL is support for views and subselects in MS SQL Server but stuff like LIMIT is not supported (though you can do a select top * ...).

There is also the matter of changing your SQL Statements to be compatible with SQL Server.  MySQL and SQL Server have quite a few differences with SQL Statements.  As far as the rest of your code, it should not matter if it's on UNIX or Windows.
