This was implemented before the SQL standard addressed the issue - if it is addressed in the SQL standard. Because it has attracted low-quality or spam answers that had to be removed, posting an answer now requires 10 reputation on this site (the association bonus does not count).My copy of the SQL 9003 standard does not show it as being standard (amongst other things, RENAME is not one of the keywords). Would you like to answer one of these unanswered questions instead?

With a 100 columns, you mostly likely have a design problem... This is possible since the sales person’s full name is common to both tables. The OUTPUT clause is used to log changes made to rows affect by an UPDATE statement.In the diagram below you’ll see where there is a match between these two tables: By matching esql Sales Person. Notice here we’re constructing a full name from the views First Name and Last Name columns. So, once we have the join, the last bit of business to it do the update. Suppose the Sales Last Year figures were found to be incorrect and needed to be adjusted by five percent.No rows from the UPDATE statement are saved into the table, even those rows that didn’t generate an error.This “all or nothing” behavior can be modified for arithmetic errors. An exclusive (X) lock is always placed on a table when an update is run.
