SQLSERVER id in string

1、函数

create Function StrToTable(@str varchar(1000))
Returns @tableName Table
(
   str2table varchar(50)
)
As
--该函数用于把一个用逗号分隔的多个数据字符串变成一个表的一列，例如字符串'1,2,3,4,5' 将编程一个表，这个表
Begin
set @str = @str+','
Declare @insertStr varchar(50) --截取后的第一个字符串
Declare @newstr varchar(1000) --截取第一个字符串后剩余的字符串
set @insertStr = left(@str,charindex(',',@str)-1)
set @newstr = stuff(@str,1,@str),'')
Insert @tableName Values(@insertStr)
while(len(@newstr)>0)
begin
   set @insertStr = left(@newstr,@newstr)-1)
   Insert @tableName Values(@insertStr)
   set @newstr = stuff(@newstr,@newstr),'')
end
Return
End

然后sql语句就可以这样了

declare str vchar(100)

set str='1,3'

select * from tablename where id in (select str2table from StrToTable(@str) )

2、charindex

SELECT * FROM   TABLE 
WHERE  CHARINDEX(','+ltrim(TABLE.COL)+','+(SELECT JKJCCODES FROM OTHER_TABLE 
 WHERE WHETHERTOEND = '1' AND DEPARTMENT_CODE = 'zz1035')+',')>0
AND TABID IS NOT NULL AND TABID <> ''
