如何在 SQL Server 2008 的单个存储过程中编写两个更新查询答案

【问题标题】：How can I write two update queries in single stored procedure in SQL Server 2008如何在 SQL Server 2008 的单个存储过程中编写两个更新查询
【发布时间】：2016-04-26 14:06:52
【问题描述】：

我有一个表，其中包含绑定到 gridview 的几列。

在那个网格视图中，我有一个编辑选项来更新列。在那种情况下，我需要编写两个更新存储过程，这意味着我选择所有列期望AudiotoName，选择另一列所有列都更新以引发一个更新查询，但是当我选择具有AudiotoName 列的表时只编辑要选择该列，它将引发第二个更新存储过程。我试过了，但它不能正常工作，谁能帮帮我。

我的代码：

ALTER PROCEDURE up_file
    (@ModuleID int,
     @SubjectID int,
     @Physician varchar(500) = '',
     @AuditoName varchar(300) = '',
     @AuditoType varchar(50) = '',
     @AudioPath varchar(2000) = '',
     @BaseDocumentName varchar(500) = '',
     @BaseDocumentPath varchar(2000) = '',
     @Createddate datetime, 
     @CreatedBy varchar(200) = '')
AS
BEGIN   
    IF @AuditoName = 'true' //select AuditoName column only raise this update query
    BEGIN
        UPDATE SubjectItems 
        SET ModuleID = @ModuleID,
            SubjectID = @SubjectID,
            Physician = '@Physician',
            AuditoName = '@AuditoName',
            AuditoType = '@AuditoType',
            AudioPath ='@AudioPath',
            BaseDocumentName = '@BaseDocumentName',
            BaseDocumentPath = '@BaseDocumentPath' 
         WHERE AuditoName = @AuditoName
    END
    BEGIN  //normal fields select raise this update query 
       UPDATE SubjectItems 
       SET ModuleID = @ModuleID,
            SubjectID = @SubjectID,
            Physician = '@Physician',
            AuditoName = '@AuditoName',
            AuditoType = '@AuditoType',
            AudioPath ='@AudioPath',
            BaseDocumentName = '@BaseDocumentName',
            BaseDocumentPath = '@BaseDocumentPath' 
         WHERE ModuleID = @ModuleID
    END
END

谁能帮帮我？

您的查询中的问题是，即使@AuditoName 为真，较低的更新查询仍在运行。这将重新更新表SubjectItems。您可以改用if...else 块，如下所示：

ALTER PROCEDURE up_file
    (@ModuleID int,
     @SubjectID int,
     @Physician varchar(500) = '',
     @AuditoName varchar(300) = '',
     @AuditoType varchar(50) = '',
     @AudioPath varchar(2000) = '',
     @BaseDocumentName varchar(500) = '',
     @BaseDocumentPath varchar(2000) = '',
     @Createddate datetime, 
     @CreatedBy varchar(200) = '')
AS
BEGIN   
    IF @AuditoName = 'true' //select AuditoName column only raise this update query
    BEGIN
        UPDATE SubjectItems 
        SET ModuleID = @ModuleID,
            SubjectID = @SubjectID,
            Physician = '@Physician',
            AuditoName = '@AuditoName',
            AuditoType = '@AuditoType',
            AudioPath ='@AudioPath',
            BaseDocumentName = '@BaseDocumentName',
            BaseDocumentPath = '@BaseDocumentPath' 
         WHERE AuditoName = @AuditoName
    END
ELSE
    BEGIN  //normal fields select raise this update query 
       UPDATE SubjectItems 
       SET ModuleID = @ModuleID,
            SubjectID = @SubjectID,
            Physician = '@Physician',
            AuditoName = '@AuditoName',
            AuditoType = '@AuditoType',
            AudioPath ='@AudioPath',
            BaseDocumentName = '@BaseDocumentName',
            BaseDocumentPath = '@BaseDocumentPath' 
         WHERE ModuleID = @ModuleID
    END
END
