【问题描述】：

在我的存储过程中，我有 SELECT 语句。我想将这些 SELECT 语句的结果作为参数传递给函数。请告诉我如何将参数传递给 SQL Server 中的函数。

我的存储过程：

CREATE PROCEDURE PositionReport                                
AS 
BEGIN 
   (select COUNT(ID) from Submissions where SubmissionStatus = 'Status1') Status1,                    
   (select COUNT(ID) from Submissions where SubmissionStatus = 'Status2') Status2,                    
   dbo.[fnGetTotal](Status1,Status1) Total                             
END

功能：

CREATE FUNCTION [dbo].[fnGetTotal](@Status1 int, @Status1 int)
RETURN varchar(100) AS
BEGIN
   DECLARE @Total varchar(100);

   SELECT @Total = @Status1 + @Status1
   RETURN @Total                           
END

我原来的存储过程：

CREATE PROCEDURE [dbo].[Usp_GetJobsPositionReport]
    @AccountID int, 
    @Userid int,
    @JobTitle varchar(100),
    @ClientID varchar(8000),
    @ContactID varchar(8000),
    @PageNum int,
    @PageSize int,
    @SortExpression varchar(1000),
    @isExport bit = 0
AS             
BEGIN
   SELECT @sqlQuery = 'SELECT * FROM (SELECT distinct ROW_NUMBER() over (ORDER BY ' + @SortExpression + ') as SNo, Jobs.JobNo, Jobs.JobID, Jobs.JobTitle, VendorClients.CompanyName Client, VendorContacts.FirstName + '' ''  + VendorContacts.LastName as ContactName, Users.FirstName + '' ''+ Users.LastName CreatedBy, (select COUNT(SubmissionID) from CandidateSubmissions where SubmissionStatus in(''Submitted'',''Screening'') and InterviewType is null and CandidateSubmissions.jobid=jobs.jobid) Submitted, (select COUNT(SubmissionID) from CandidateSubmissions where SubmissionStatus not in (''Potential'',''Rejected'',''Attached'',''CandidateWithdrawn'',''Backout'',''Matched'') and CandidateSubmissions.jobid=jobs.jobid) Active,

                   (select COUNT(SubmissionID) from CandidateSubmissions where SubmissionStatus = ''OfferNegotiating'' and CandidateSubmissions.jobid=jobs.jobid) OfferNegotiating,

【问题讨论】：

SQL server 是 2005 还是 2008？
在查看编辑历史记录之前，我对这个问题感到非常困惑。似乎有人（嗨@juergend！）偷偷地将参数添加到函数调用中！
@DavidG：你在说什么？除了格式化，问题没有添加任何内容。
@juergend 查看编辑历史。原文是dbo.fnGetTotal Total，您的编辑是dbo.[fnGetTotal](Status1,Status1) Total
@DavidG：我想这是一个竞争条件。 OP 和我可能同时编辑。我只点击了该帖子上的格式按钮，没有输入任何字符。

【解决方案1】：

如下更改您的程序

CREATE PROCEDURE PositionReport                                                                                                             
as                                                                                                                                      
BEGIN 

DECLARE @Status1 int
DECLARE @Status2 int


select @Status1=COUNT(ID) from Submissions where SubmissionStatus = 'Status1'                   
select @Status2=COUNT(ID) from Submissions where SubmissionStatus = 'Status2'                    

SELECT @Status1 as Status1,@Status2 as Status2
       ,dbo.[fnGetTotal](@Status1,@Status1) Total                             
END

但我不认为需要单独的函数，除非你正在做更复杂的事情。

【讨论】：

对不起，其实我的sp如下。例如，我已经给出了。
我更新了我的SP，请检查并给我任何建议。谢谢。

【解决方案2】：

只需将 select 语句本身（作为字符串）传递给存储的函数，而不是其结果，然后在函数内部运行它。

要从字符串运行一些 SQL 命令，请使用：

sys.sp_executesql

例子：

EXEC sys.sp_executesql N'select ''Hello world'' as Result'
