The code posted is basic SQL. It will work for Access. It's not even remotely close to PHP, although he used [php] tags to post it.

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[Table]') AND type in (N'U'))
CREATE TABLE [dbo].[Table](
  {snip}
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY] 

Hey GremlinSA,

What do the functions *_ID*, *N*, and *type* do? Could you explain a little about what's going on?

Thanks,

What do the functions *_ID*, *N*, and *type* do? Could you explain a little about what's going on?

Its a little easier to see whats going on if you run the query yourself and look at the results. Forget the WHERE clause he put in there and just run

USE [DatabaseName];
SELECT * FROM sys.objects;

You should see that this table holds a list of all the objects in the database consisting of Tables, Primary Keys, Foreign Keys, and other constraints. Each object has an ID associated with it.

The *N* prefix to the string just allows the string to contain Unicode characters.

The OBJECT_ID( ) just returns the corresponding id in the sys.objects table for the table you're looking for.

Lastly the *type* isn't really a function its just another column in the database. In this situation N'U' just tells the query you're only interested in tables. You can add in the other types if you wish to the search but for this situation all you're interested in are the tables. Oh, and 'U' stands for USER_TABLE.
