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:...
建立「分類函數」(Classifier Function),它是使用者定義的函數 (UDF),而且資源管理員會使用其傳回值來分類工作階段,以便將它們路由傳送至適當的工作負載群組。 向資源管理員註冊此分類函數。 將這些變更套用至資源管理員的記憶體中組態。 注意 如需有關資源管理員資源集區、工作負載群組和分類的相關資訊,請參閱資源...

then destroy the object. For most purposes this was too inefficient and caused too many performance problems. The only alternative was to create an extended stored procedure. However, now there's SQLCLR, a CLR user-defined function (UDF) that lets you create an efficient and less error-prone...
I've never really had to debug a function before as I assume you would run the code as select first before inserting into a user defined function. USE [HealthBI] GO /*** Object: UserDefinedFunction [dbo].[udf_INS_CDSGetCommissionerCode] Script Date: 03/10/2017 09:04:42 ***/ SET...
Additional privileges are required if the function uses a table as a parameter, refers to a distinct type, or is to run in a WLM (workload manager) environment. These privileges are: The SELECT privilege on any table that is an input parameter to the function. ...

Not enough random access memory (RAM) is available to process the command. If a remote procedure was invoked, the remote procedure may use a local variable space that is larger than the allowable maximum (4K). If the statement involves a user-defined function (UDF), the memory set controlle...
