如何在存储过程 SQL Server 2008 中使用“IN”运算符传递字符串参数

Question

我有一个存储过程，当我执行它时出现错误

将 varchar 值 '+@dptId+' 转换为数据类型 int 时转换失败

我将DepartmentId 作为一个字符串，如(1,3,5,77)，并将其传递给我的存储过程。

SQL FIDDLE

create table dummy (id int,name varchar(100),DateJoining Datetime, departmentIt int)

insert into dummy values (1,'John','2012-06-01 09:55:57.257',1);
insert into dummy  values(2,'Amit','2013-06-01 09:55:57.257',2);
insert into dummy  values(3,'Naval','2012-05-01 09:55:57.257',3);
insert into dummy  values(4,'Pamela','2012-06-01 09:55:57.257',4);
insert into dummy  values(5,'Andrea','2012-09-01 09:55:57.257',3);
insert into dummy  values(6,'Vicky','2012-04-01 09:55:57.257',4);
insert into dummy  values(7,'Billa','2012-02-01 09:55:57.257',4);
insert into dummy  values(8,'Reza','2012-04-01 09:55:57.257',3);
insert into dummy  values (9,'Jacob','2011-05-01 09:55:57.257',5);

我试过的查询：

declare @startdate1 varchar(100) ='20120201'
declare @enddate1 varchar(100)='20130601'
declare @dptId varchar(100)='3,4'

select * 
from dummy
where DateJoining >= @startdate1 and DateJoining < @enddate1 
  and departmentIt IN (@dptId);

我是这样解决的：Working SQL Fiddle

首先我创建了一个拆分字符串值的函数，即'1,2,4,5'

拆分功能：

CREATE  FUNCTION fn_Split(@text varchar(8000), @delimiter varchar(20) = ' ')
RETURNS @Strings TABLE
(   
  position int IDENTITY PRIMARY KEY,
  value varchar(8000)  
)
AS
BEGIN

DECLARE @index int
SET @index = -1

WHILE (LEN(@text) > 0)
  BEGIN 
    SET @index = CHARINDEX(@delimiter , @text) 
    IF (@index = 0) AND (LEN(@text) > 0) 
      BEGIN  
        INSERT INTO @Strings VALUES (@text)
          BREAK 
      END 
    IF (@index > 1) 
      BEGIN  
        INSERT INTO @Strings VALUES (LEFT(@text, @index - 1))  
        SET @text = RIGHT(@text, (LEN(@text) - @index)) 
      END 
    ELSE
      SET @text = RIGHT(@text, (LEN(@text) - @index))
    END
  RETURN
END

稍后在我的查询中，我使用了拆分函数

declare @startdate1 varchar(100) ='20120201'
declare @enddate1 varchar(100)='20130601'
declare @dptId varchar(100)='3,4'

select * from dummy
where DateJoining >=@startdate1 and DateJoining < @enddate1 
  and departmentID IN (SELECT Value FROM fn_Split(@dptId, ','));

Answer 2

尝试使用sp_executesql 作为答案。不是最有效的，但它确实有效

ALTER PROCEDURE [dbo].[uspTestReportData_GetBySerial] 
    @SerialNumbers nvarchar(200)
AS
BEGIN
    SET NOCOUNT ON;
    declare @sql nvarchar(200)

    set @sql = 'SELECT * from MyTable WHERE  Serial_Number in (' + @SerialNumbers + ')'
    execute sp_executesql @sql                    

END

Answer 3

简单地说，你可以做到以下SELECT：

SELECT M.REG_NO, T.TYPE_ID 
    FROM MAIN AS M 
        INNER JOIN CLASSIFICATION AS C 
            ON M.REG_NO = C.REG_NO
        INNER JOIN TYPE AS T 
            ON T.TYPE_ID = C.TYPE_ID
    WHERE (','+@Types+',') LIKE '%,' +T.TYPE_ID+ ',%'
