Following is the sql query:

select  SKU,PRODUCTNAME,PRODUCTVARIANT from tbl_product where SKU  in(SELECT * FROM splitstring('ewew,slk,ewew'))

I need to get 3 rows(with duplicate) but in Query will return only 2 rows.

What can i do to get 3 rows?

THanks

What I have tried:

Right now, I'm getting only 2 rows.

The splitstring function is splitting the strings into 3 rows.

select SKU,PRODUCTNAME,PRODUCTVARIANT from tbl_product where product in(SELECT * FROM STRING_SPLIT('ewew,slk,ewew',','))
STRING_SPLIT only works when you have SQL SERVER 2016

The query seem ok.

Can you test the following query?

SQL

select  SKU,PRODUCTNAME,PRODUCTVARIANT from tbl_product where SKU  in ('ewew','slk')

The query should produce three rows. If it still two that mean that could be data issue on the tbl_product table. It could be extra space on the SKU or something.

If the query return 3 rows that could signal that the splitstring function might be an issue.

Solution 1

Use a JOIN instead:

SQL

select
    P.SKU,
    P.PRODUCTNAME,
    P.PRODUCTVARIANT 
from 
    tbl_product As P
    INNER JOIN splitstring('ewew,slk,ewew') As S
    ON S.VALUE = P.SKU
;

NB: You'll obviously need to replace S.VALUE with the correct column name returned from your splitstring function.

This is the function

Create FUNCTION [dbo].[splitstring] ( @stringToSplit VARCHAR(MAX) )
RETURNS
@returnList TABLE ([Name] [nvarchar] (500))
AS
BEGIN

DECLARE @name NVARCHAR(255)
DECLARE @pos INT

WHILE CHARINDEX(',', @stringToSplit) > 0
BEGIN
SELECT @pos = CHARINDEX(',', @stringToSplit)
SELECT @name = SUBSTRING(@stringToSplit, 1, @pos-1)

INSERT INTO @returnList
SELECT @name

SELECT @stringToSplit = SUBSTRING(@stringToSplit, @pos+1, LEN(@stringToSplit)-@pos)
END

INSERT INTO @returnList
SELECT @stringToSplit

RETURN
END

So as I said, replace S.VALUE with S.Name.
