Is there any way or query to count no. of column in a given table???

like we can count Row by the help of aggregate function COUNT so is there any other function which help to count column.

This should work: ------------- SELECT count(*) FROM information_schema.columns WHERE table_schema = 'database_name' AND table_name = 'table_name'; ------------- Just replace database_name and table_name with the actual names for your database and table.

Um... well... your question is a bit vague. Generally speaking, get experience with Entity Framework. Datasets are part of EF. LINQ to SQL really isn't something used in development projects I've been involved in. It's good for quick prototyping. But so is EF.
