Updating multiple rows without cursor

Next, we'll declare our cursor, open it and move it to the first record.

There are 15 rows in the employee table and so this won’t illustrate the performance issues that cursors can suffer but if the table contained The above code creates two variables @Emp Id and @Emp Name that will hold the id and name from the employee table respectively.You can add more column names in a comma-separated list if you need to make more fields updatable.To demonstrate how to use a cursor to update records we'll create a running total of the number of Oscars our films have won.I figure I can put the WHILE loop in a UDF and call the UDF in the SELECT clause.My plan was to raise an error when a circular reference was found but its saying 'Invalid use of 'RAISEERROR' within a function.'.
