Question

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

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

我的原始存储过程：

CREATE PROCEDURE [dbo].[Usp_GetJobsPositionReport]
    @AccountID int, 
    @Userid int,
    @JobTitle varchar(100),
    @ClientID varchar(8000),

    @PageSize int,
    @SortExpression varchar(1000),
    @isExport bit = 0

   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,

按以下步骤更改您的程序

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

但是我不认为除非你做一些更复杂的事情，否则需要一个单独的功能。

Answer 2

只需将自身（作为字符串）的select语句（而不是结果）传递给存储的函数，然后在函数内部运行它即可。

要从字符串中运行一些SQL命令，请使用：

sys.sp_executesql

示例：

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

如何将SELECT语句结果作为参数传递给SQL Server中的存储过程中的函数？
