Passing a varchar full of comma delimited values t

Question

Dynamic SQL Comma Delimited Value Query

I have a SQL Server Stored Procedure where I would like to pass a varchar full of comma delimited values to an IN function. For example:

DECLARE @Ids varchar(50);
SET @Ids = '1,2,3,5,4,6,7,98,234';

SELECT * 
FROM sometable 
WHERE tableid IN (@Ids);

This does not work of course. I get the error:

Conversion failed when converting the varchar value '1,2,3,5,4,6,7,98,234' to data type int.

How can I accomplish this (or something relatively similar) without resorting to building dynamic SQL?

Answer 1

I can suggest using WITH like this:

DECLARE @Delim char(1) = ',';
SET @Ids = @Ids + @Delim;

WITH CTE(i, ls, id) AS (
    SELECT 1, CHARINDEX(@Delim, @Ids, 1), SUBSTRING(@Ids, 1, CHARINDEX(@Delim, @Ids, 1) - 1)
    UNION ALL
    SELECT i + 1, CHARINDEX(@Delim, @Ids, ls + 1), SUBSTRING(@Ids, ls + 1, CHARINDEX(@Delim, @Ids, ls + 1) - CHARINDEX(@Delim, @Ids, ls) - 1)
    FROM CTE
    WHERE  CHARINDEX(@Delim, @Ids, ls + 1) > 1
)
SELECT t.*
FROM yourTable t
    INNER JOIN
    CTE c
    ON t.id = c.id;

You could do it like this:

create or replace 
PROCEDURE UDP_SETBOOKMARK 
(
  P_USERID IN VARCHAR2  
, P_BOOKMARK IN VARCHAR2  
) AS 
BEGIN

UPDATE T_ER_Bewertung
SET LESEZEICHEN = P_BOOKMARK
WHERE STAMM_ID in( select regexp_substr(P_USERID,'[^,]+', 1, level) from dual
                   connect by regexp_substr(P_USERID, '[^,]+', 1, level) is not null )
and ER_ID = (select max(ER_ID) from T_ER_Bewertung_Kopie);

commit;

END UDP_SETBOOKMARK;

Then try it with

Begin
UDP_SETBOOKMARK ('1,2,3,4,5', 'Test');
End;

You can use this IN-Clause with regexp_substr in other situations too, just try it.

CREATE TABLE t 
  ( 
     id   INT, 
     col1 VARCHAR(50) 
  ) 

INSERT INTO t 
VALUES     (1, 
            'param1') 

INSERT INTO t 
VALUES     (2, 
            'param2') 

INSERT INTO t 
VALUES     (3, 
            'param3') 

INSERT INTO t 
VALUES     (4, 
            'param4') 

INSERT INTO t 
VALUES     (5, 
            'param5') 

DECLARE @params VARCHAR(100) 

SET @params = ',param1,param2,param3,' 

SELECT * 
FROM   t 
WHERE  Charindex(',' + Cast(col1 AS VARCHAR(8000)) + ',', @params) > 0

Of course if you're lazy like me, you could just do this:

Declare @Ids varchar(50) Set @Ids = ',1,2,3,5,4,6,7,98,234,'

Select * from sometable
 where Charindex(','+cast(tableid as varchar(8000))+',', @Ids) > 0

I have same idea with user KM. but do not need extra table Number. Just this function only.

CREATE FUNCTION [dbo].[FN_ListToTable]
(
    @SplitOn              char(1)              --REQUIRED, the character to split the @List string on
   ,@List                 varchar(8000)        --REQUIRED, the list to split apart
)
RETURNS
@ParsedList table
(
    ListValue varchar(500)
)
AS
BEGIN
    DECLARE @number int = 0
    DECLARE @childString varchar(502) = ''
    DECLARE @lengthChildString int = 0
    DECLARE @processString varchar(502) = @SplitOn + @List + @SplitOn

    WHILE @number < LEN(@processString)
    BEGIN
        SET @number = @number + 1
        SET @lengthChildString = CHARINDEX(@SplitOn, @processString, @number + 1) - @number - 1
        IF @lengthChildString > 0
        BEGIN
            SET @childString = LTRIM(RTRIM(SUBSTRING(@processString, @number + 1, @lengthChildString)))

            IF @childString IS NOT NULL AND @childString != ''
            BEGIN
                INSERT INTO @ParsedList(ListValue) VALUES (@childString)
                SET @number = @number + @lengthChildString - 1
            END
        END
    END

RETURN

END

And here is the test:

SELECT ListValue FROM dbo.FN_ListToTable('/','a/////bb/c')

Result:

   ListValue
______________________
   a
   bb
   c

-- select * from dbo.Split_ID('77,106')  

    ALTER FUNCTION dbo.Split_ID(@String varchar(8000))     
    returns @temptable TABLE (ID varchar(8000))     
    as     
    begin     
        declare @idx int     
        declare @slice varchar(8000)     
        declare @Delimiter char(1)
         set @Delimiter =','

        select @idx = 1     
            if len(@String)<1 or @String is null  return     

        while @idx!= 0     
        begin     
            set @idx = charindex(@Delimiter,@String)     
            if @idx!=0     
                set @slice = left(@String,@idx - 1)     
            else     
                set @slice = @String     

            if(len(@slice)>0)
                insert into @temptable(ID) values(@slice)     

            set @String = right(@String,len(@String) - @idx)     
            if len(@String) = 0 break     
        end 
    return     
    end
