Hi, How many primary key constraints can we have in a table of ms-access? Any other constraints available in ms-access other than primary key? Please share your ideas... Thanks, Sivakumar.M.

This question has nothing to do with .NET. Please ask in the Database forum.

For all its in the wrong forum..... How many primary key constraints can you have in any database table? That'll be one, although the primary key can be made up multiple columns.
