1237 Allows the ALTER PARTITION FUNCTION statement to honor the current user-defined session deadlock priority instead of being the likely deadlock victim by default. For more information, see KB4025261.Note: Starting with SQL Server 2017 (14.x) and database compatibility level 140 this is the...
建立使用者定義函式 (UDF),這是 Transact-SQL 或 Common Language Runtime (CLR) 例程。 使用者定義函式接受參數、執行像是複雜計算的動作,並將該動作的結果當做值傳回。 傳回值可以是純量 (單一) 值或資料表。 您可以使用這個陳述式來建立可用下列方式使用的可重複使用常式:...
