Thanks Ray. I tried that but I must be getting the syntax wrong. Can you post a sample for a table called MATRIX?

I believe he meant:
select * from information_schema.columns

Try:
SELECT
sysobjects.id as TableID,
sysobjects.name as Table_Name,
syscolumns.name as Field_Name,
systypes.name as Field_Type,
systypes.length as Field_Length,
syscolumns.isnullable as Allow_Null,
syscomments.text as Default_Value
FROM syscolumns
INNER JOIN systypes on systypes.xusertype = syscolumns.xusertype
INNER JOIN sysobjects on sysobjects.id = syscolumns.id
LEFT OUTER JOIN sysobjects as Defaults on Defaults.id = syscolumns.cdefault
LEFT OUTER JOIN syscomments on syscomments.id = Defaults.id
WHERE sysobjects.xtype = 'U'
order by sysobjects.name, syscolumns.colorder
This'll give more info than you're looking for, but you can pare it down by reducing the joins and/or adding to the WHERE clause for the table name.

Hi Randy,
Here is, some intresting Stored Procedure that can help you more.
Sp_Help <Tablename> displays all the information regarding a given table. When information is required only on one particular field then this stored procedure can be used with SQL Server 7.0. Syntax: sp_HelpTableField 'TableName' , 'Substring of FieldName'. All the field names matching this 'Substring' will be displayed.
create proc sp_helpTableField
