Answer 1

You can write a nested query as follows:

SELECT [CategoryID], [CategoryName], [Description], [Picture], (SELECT COUNT(*) FROM SOURCE_TABLE_NAME WHERE [CategoryID]=a.[CategoryID]) as [CATCOUNT] FROM [Categories] a

Where SOURCE_TABLE_NAME is the table name from where you want category count to be taken.
