Hello Again,
Today we have a surprise for everyone in the form of a bonus database update. This update doesn’t add any new cards, but it does make some changes to the list of sets you can select from when performing a search. This update will group together all the Commander sets together and also adds Duel Decks: Anthologies and Portal Three Kingdoms to the list (the cards were always available, but we missed putting them in the list).
if you want the database to execute the update operation only if the specified condition is true. The condition can refer to either the data source or the target table. If the condition is not true, then the database skips the update operation when merging the row into the table.
