SQL Server error code
SQL Server error 264
SQL Server raises error 264 at severity 16, which marks a problem with the query or data that you can correct.
The column name '%.*ls' is specified more than once in the SET clause or column list of an INSERT. A column cannot be assigned more than one value in the same clause. Modify the clause to make sure that a column is updated only once. If this statement updates or inserts columns into a view, column aliasing can conceal the duplication in your code.
