WebImportant If the checksums for two tables are different, then it is almost certain that the tables are different in some way. However, because the hashing function used by CHECKSUM TABLE is not guaranteed to be collision-free, there is a slight chance that two tables which are not identical can produce the same checksum. WebYou cannot call this function directly. This function can only appear within a LINQ to Entities query. This function is translated to a corresponding function in the database. For information about the corresponding SQL Server function, see CHECKSUM (Transact-SQL).
