在SQL Server 中,创建表值函数的基本语法如下: CREATEFUNCTIONdbo.MyFunction(@Parameter1INT,@Parameter2VARCHAR(50))RETURNSTABLEASRETURN(SELECTColumn1,Column2FROMMyTableWHEREColumn1=@Parameter1ANDColumn2=@Parameter2) 1. 2.
適用於:SQL Server 本文是關於在完整復原模式下,包含多個檔案或檔案群組的 SQL Server 資料庫。 這個範例當中,使用完整復原模式,名為 adb的資料庫包含三個檔案群組。 檔案群組 A 可讀取/寫入,而檔案群組 B 和檔案群組 C 則是唯讀的。 所有的檔案群組一開始都是在線上。 檔案...
從命令提示字元中安裝新的 SQL Server 執行個體,可讓您指定要安裝的功能以及這些功能應該設定的方式。 您也可以指定與安裝程式使用者介面的無訊息、基本或完整互動。若要從命令提示字元中安裝或設定您的 SQL Server 執行個體,請開啟系統管理命令提示字元,並巡覽至 setup.exe 位於SQL Server 安裝媒體內的位置。
The other method that we will refer as the “Fill Row method” must receive an object and one parameter for each output column of the table valued function. These parameters are passed by reference to this function, meaning that we have to set the value for each of the parameters in order...

如果RETURNS 子句指定的 TABLE 类型带有列及其数据类型,则该函数是多语句表值函数。 内联表值函数范例: CREATE FUNCTION Sales.ufn_SalesByStore (@storeid int) RETURNS TABLE AS RETURN ( SELECT P.ProductID, P.Name, SUM(SD.LineTotal) AS 'YTD Total' ...
table lists the SQLSTATE values typically returned bySQLTablesand explains each one in the context of this function; the notation "(DM)" precedes the descriptions of SQLSTATEs returned by the Driver Manager. The return code associated with each SQLSTATE value is SQL_ERROR, unless noted ...
Table-valued functions can return a table when: Created from scalar input arguments. For example, a table-valued function that takes a comma-delimited string of numbers and pivots them into a table. Generated from external data. For example, a table-valued function that reads the event log an...
Valued Functions. It has been distinguished that Inline Table-Valued Functions perform better than Multi Statement Table-Value Functions. If your code uses Multi Statement Table-Valued Functions you could have a performance bottleneck and the function can perform differently based...
