Got a quick question, Is there a way to count the columns in an access table before process it and inserting that data into a SQL table?

I have some C# which enumerates the columns in an Access table. Is that of any interest?

I'm thinking the ACE drivers might let you do such a thing directly.

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

I do use the ACE drivers to connect to Access DBs from C#, but 'directly' is an overly generous description of the way in which columns in a specific named table can be analysed. At least that's true of my method; no doubt there are better ways out there.

If you're doing it from within SSIS, I'd do what Phil said... if you're reading from Access, then you can do this:
DBEngine(0)(0).Tabledefs("TableName").Columns.Count will work if you're reading from the current database inside Access.
