the return value of a stored procedure is actually one of the parameters which has the type Return. there are also input and output parameters. just like the return parameter, output parameters are only valid after all result sets are read. if using a data reader, you need to read all ...

1 通过封装实现重用性和逻辑复杂性的隐藏。仅需要通过存储过程的修改(alter procedure)就能应用新的逻辑。 2 减少网络的传输,这是因为存储过程即存储在数据库里,而如果是应用程序方式访问数据库识别有网络传输的成本。 3 存储过程可以提供对数据库进行安全的访问,即赋予了执行存储过程的用户不能直接访问底层的数据库对...

當資料庫需給其他Developer使用時,不需開放整個Table的讀取或寫入權限,只需開放Stored Procedure的使用權限即可,因此對權限可以有較嚴謹控制。 4.執行速度:每次使用Ad Hoc Query時,SQL Server的CPU time非常高,需重新Parse,且重新製作Execution Plan,但使用Stored Procedure時,只有第一次執行時CPU time較高,此時為了製...

Also you should avoid using the return code to return application data. Examples of return codes The following example shows the usp_GetSalesYTD procedure with error handling that sets special return code values for various errors. The following table shows the integer value that is assi...
</MT_Employee_Procedure> As far as I know the type CURSOR is not supported in XI. Is there a way of returning cursor information using stored procedures? There is no cursor support in XI. Similar to a table-select, the store procedure will return a resultset. ...
