Using parameter values in an IN clause

  • I've been struggling with how to get SRS to let me pass a string value as a parameter into an IN clause and I'm stumped.

    I've got the following simple scenario:

    SELECT     DisplayName, LastName, Department
    FROM         tblEmployee
    WHERE     (UserName IN (@usernames))

    And am trying to pass a few usernames into the parameter for the report.  Passing a single username such as asmith works fine, but if I go with multiple values I get no results, for example the following fails: asmith,bjones.

    I've tried a number of different iterations of what I feed the parameter:

    asmith,bjones

    'asmith','bjones'

    asmith','bjones (thinking that perhaps the leading and trailing quotes were being added for me)

    All with no luck.  Does anyone know if this will work and what I'm missing?  Thanks for any help =)

  • Unfortunately for you, you are doing nothing incorrect.  At this time (haven't tried with SQL 2K5) you can't get there from here.  The IN clause doesn't know how to interpret the @var as anything except a literal.

    THe only way that I know of to get around this is to build dynamic SQL and use either EXEC @SQL or EXEC sp_executesql @SQL to get what you want...

  • yep, yep, yep

    Use a temporary table variable

     

    use pubs

    set nocount on

    declare @Usernames varchar(5000)

    set @Usernames = 'me,him,she,them,Karin'

    declare @TblUserNames TABLE

     (UserNamesId int IDENTITY(1, 1) NOT NULL PRIMARY KEY,

      UserName varchar(128) not NULL)

    -- snipped from tcartwright he as a function to do this

    -- http://www.sqlservercentral.com/scripts/contributions/592.asp

     DECLARE @Delimiter2 varchar(12),@Delimiter varchar(12),

      @UserName varchar(128),

      @iPos int,

      @DelimWidth int

     

     --had to do this cuz if they send in a > 9 char delimiter I could not pre and post append the % wildcards

     SET @Delimiter2 = ','

     SET @Delimiter2 = ISNULL(@Delimiter2, ',')

     SET @DelimWidth = LEN(@Delimiter2)

     IF RIGHT(RTRIM(@UserNames), 1) <> @Delimiter2     

      SELECT @UserNames = RTRIM(@UserNames) + @Delimiter2

     

     IF LEFT(@Delimiter2, 1) <> '%'

      SET @Delimiter2 = '%' + @Delimiter2

     

     IF RIGHT(@Delimiter2, 1) <> '%'

      SET @Delimiter2 = @Delimiter2 + '%'

     

     SELECT @iPos = PATINDEX(@Delimiter2, @UserNames)

     

     WHILE @iPos > 0

     BEGIN

      SELECT @UserName = LTRIM(RTRIM(LEFT(@UserNames, @iPos - 1)))

      IF @@ERROR <> 0 BREAK

      SELECT @UserNames =  RIGHT(@UserNames, LEN(@UserNames) - (LEN(@UserName) + @DelimWidth))

      IF @@ERROR <> 0 BREAK

      

      INSERT INTO @TblUserNames VALUES(@UserName)

      IF @@ERROR <> 0 BREAK

     

      SELECT @iPos = PATINDEX(@Delimiter2, @UserNames)

      IF @@ERROR <> 0 BREAK

     END

    -- select * from @TblUserNames

    SELECT     emp_id, LName, hire_date

    FROM         Employee E

    inner join @TblUserNames U

    on E.fname = U.UserName

     

    With tcartwright's function 

    ( http://www.sqlservercentral.com/scripts/contributions/592.asp)

    This would even be more easy

    select e.*

    from pubs..employee E

    inner join dbo.fnSplit('me,him,she,them,Karin',',') U

    on E.fname = U.item

  • Try this

    The UDF is one I use alot, as alot of "old" db's use string values with a delim.  ....

  • Hi all,

    I also had a problem with using var in "IN" clause...

    but for case that you describing you can try something like this

    select * from sometable

    where userid in (select userid from userslisttable

    where CHARINDEX(','+userlisttable.userid+',', ','+@parameter+',')>0 )

    Hope, it helps

     


    Kindest Regards,

    Maksim
