It is frequently useful to save the values of system variables in tables when the package is run 通常在包運(yùn)行時(shí),需要在表中保存系統(tǒng)變量的值。
The following table describes the system variables that integration services provides for tasks 下表介紹integration services為任務(wù)提供的系統(tǒng)變量。
The following table describes the system variables that integration services provides for packages 下表介紹integration services為包提供的系統(tǒng)變量。
Describes user - defined variables and the system variables that integration services provides 介紹用戶定義的變量和integration services提供的系統(tǒng)變量。
System variables contain useful information about a package , container , task , or event handler 系統(tǒng)變量包含有關(guān)包、容器、任務(wù)或事件處理程序的非常有用的信息。
To verify that the path of sql plus appears in the system path , examine the value of the system variable 若要驗(yàn)證sql * plus的路徑是否顯示在系統(tǒng)路徑中,請(qǐng)檢查系統(tǒng)變量
Integration services supports two types of variables : user - defined variables and system variables Integration services支持兩種類型的變量:用戶定義的變量和系統(tǒng)變量。
The following table describes the system variables that integration services provides for event handlers 下表介紹integration services為事件處理程序所提供的系統(tǒng)變量。
The only configurable option on system variables is specifying whether they raise an event when they change value 對(duì)系統(tǒng)變量唯一可配置的選項(xiàng)是指定變量在更改值時(shí)是否引發(fā)事件。
Namespace , add variables to the system namespace , or assign system variables to a different namespace 命名空間的名稱,也不能向此命名空間添加變量或?qū)⑾到y(tǒng)變量分配到其他命名空間。
