Sql updating multiple rows
When SET ANSI_PADDING OFF then CHAR data types are padded with spaces, VARCHAR data types have trailing spaces removed, and VARBINARY have trailing zeros removed.
Keep in mind that when updating data in columns whose data type is CHAR, VARCHAR, or VARBINARY, the padding or truncation of data depends upon the SET ANSI_PADDING setting.
Knowing that esql Sales Person was originally populated by information from Sales we use knowledge to set up a query that pumps data from v Sales Person into esql Sales Person.
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.
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.
The lock is held in place until the update statement completes.In this article we’ll explore how to use the UPDATE statement.
