| SQL Server編寫存儲過程小工具? eNet技術學院，版權所有，任何人不得私自復制，轉載！違者必究??！ 在開發數據庫系統的過程中，經常要寫很多的存儲過程。為了統一格式和簡化開發過程，我編寫一些存儲過程，用來自動生成存儲過程。下面就為您簡單介紹一下它們。其中一個用于生成Insert過程，另一個用于生成Update過程。 Sp_GenInsert 該過程運行后，它為給定的表生成一個完整的Insert過程。如果原來的表有標識列，您得將生成的過程中的SET IDNTITY_INSERT ON 語句手工刪除。 語法如下 sp_GenInsert < Table Name >,< Stored Procedure Name > 以northwind 數據庫為例 sp_GenInsert ’Employees’, ’INS_Employees’ 最后會生成一個Insert存儲過程。利用它，您可以作進一步的開發。 Sp_GenUpdate 它會為一個表生成update存儲過程。語法如下： sp_GenUpdate < Table Name >,< Primary Key >,< Stored Procedure Name > 以northwind 數據庫為例 sp_GenUpdate ’Employees’,’EmployeeID’,’UPD_Employees’ 運行后生成如下所示的存儲過程： Create Procedure UPD_Employees @EmployeeID int @LastName nvarchar(40) , @FirstName nvarchar(20) , @Title nvarchar(60) , @TitleofCourtesy nvarchar(50) , @BirthDate datetime , @HireDate datetime , @Address nvarchar(120) , @City nvarchar(30) , @Region nvarchar(30) , @PostalCode nvarchar(20) , @Country nvarchar(30) , @HomePhone nvarchar(48) , @Extension nvarchar(8) , @Phote image , @Notes ntext , @ReportsTo int , @PhotoPath nvarchar(510) AS UPDATE Employees SET LastName = @LastName, FirstName = @FirstName, Title = @Title, TitleofCourtesy = @TitleofCourtesy, BirthDate = @BirthDate, HireDate = @HireDate, Address = @Address, City = @City, Regin = @Regin, PostalCode = @PostCode, Country = @Country, HomePhone = @HomePhone, Extension = @Extension, Photo = @Photo Notes = @Notes， ReportsTo = @ReportsTo, PhotoPath = @PhotoPath WHERE EmployeeID = @EmployeeID 使用以上的兩個存儲過程，節省了我不少時間。特別是在改變了表結構后，重新構造各個存儲過程的過程中。您可以改寫這兩個程序，來自動生成別的存儲過程。 |
