如何在SQL Server 2008中的单个存储过程中编写两个更新查询

Question

我有一个表包含绑定到gridview的几列.

在该gridview中,我有一个用于更新列的编辑选项.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表中的那个AudiotoName列只编辑以选择该列时它将提出第二次更新存储过程.我试过,但没有正常工作,任何人都可以帮助我.

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

谁能帮我吗？

您的查询中的问题是，即使为@AuditoNametrue，较低的更新查询仍在运行。这将重新更新表SubjectItems。您可以使用if...else块代替，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
