If the table to which the trigger is attached is in the TEMP database, then the unqualified name of the table being updated is resolved in the same way as it is for a top-level statement by searching first the TEMP database, then the main database, then any other databases in the order they were attached.

The "target" table is the specific table that is being updated. The statement would look like this:. The subquery in the FROM clause computes the amount by which the inventory should be reduced for each itemId.

That subquery is joined against the inventory table and the quantity of each affected inventory row is reduced by the appropriate amount. The target table is not included in the FROM clause, unless the intent is to do a self-join against the target table. In the event of a self-join, the table in the FROM clause must be aliased to a different name than the target table.

If the join between the target table and the FROM clause results in multiple output rows for the same target table row, then only one of those output rows is used for updating the target table.
