How to pass a list or array to a mssql procedure "WHERE IN" query ?04.02.15

example using php

1.
convert the array into a string via implode
$list = implode('|',$array);

2.
send it as a string to the mssql procedure:
$return = "exec zz_my_procedure_name @list='{$list}'";

3.
on the mssql server create a new function:

CREATE FUNCTION MYDB.[dbo].[fnSplit](
    @sInputList VARCHAR(8000) -- List of delimited items
  , @sDelimiter VARCHAR(8000) = ',' -- delimiter that separates items
) RETURNS @List TABLE (item VARCHAR(8000))

BEGIN
DECLARE @sItem VARCHAR(8000)
WHILE CHARINDEX(@sDelimiter,@sInputList,0) <> 0
 BEGIN
 SELECT
  @sItem=RTRIM(LTRIM(SUBSTRING(@sInputList,1,CHARINDEX(@sDelimiter,@sInputList,0)-1))),
  @sInputList=RTRIM(LTRIM(SUBSTRING(@sInputList,CHARINDEX(@sDelimiter,@sInputList,0)+LEN(@sDelimiter),LEN(@sInputList))))

IF LEN(@sItem) > 0
  INSERT INTO @List SELECT @sItem
 END

IF LEN(@sInputList) > 0
 INSERT INTO @List SELECT @sInputList -- Put the last item in
RETURN
END

4.
than in your procedure use the WHERE IN with a select to your fnSplit function

SELECT * FROM MYTABLE 
WHERE MYCOLUMN IN(SELECT item FROM fnSplit(@list, ‘|’))
