Question

我有一个存储过程：

CREATE Procedure [dbo].[GetCOIOrganizations]  
(  
 @orgName varchar(75)   
)  
AS  
BEGIN  

 SET NOCOUNT ON  

 Select Id,  
  [Name],  
  Description,   
  AdmPersonId,  
  Active,  
  Reviewed,  
  DateCreated  
 FROM COIOrganization Org  
 WHERE Org.[Name] like @orgName + '%'  
  AND (Org.Reviewed = 0 OR (Org.Reviewed = 1 AND Org.Active = 1))  

 order by [Name] ASC  

END

我想在此包含一个条件，如果实体（org。[Name]）已经存在，那么给出一些验证。我该怎么做？

您可以像这样使用IF EXISTS检查：

IF EXISTS ( SELECT TOP 1
                1
            FROM
                COIOrganization Org
            WHERE
                Org.[Name] LIKE @orgName + '%' )
BEGIN
    SET
            flag = 1
END
ELSE
BEGIN
    SET
            flag = 0
END

使用存储过程检查实体是否存在的条件
