Comparing Comma Separate Value with Comma Separated Values SQL - sql

Question

I have a table A which contain column "ColumnName" (it will contain the comma separated integer values ) and I have store procedure which take parameter which is also comma separated integer values.
For example I have values in table "101,102,103" and "103,104,105" and User input is "101,104" it should return 2 record. how can I achieve this?
Need SQL statements

Answer 1

This should do it:
CREATE PROCEDURE GetMatches(#input varchar (100))
AS
BEGIN
WITH CTE AS
(
SELECT value AS number
FROM STRING_SPLIT(#input, ',')
)
SELECT CTE.number, A.ColumnName
FROM A
INNER JOIN CTE
ON ',' + A.ColumnName + ',' LIKE '%,' + CTE.number + ',%';
END
You can test the stored procedure like this:
EXEC dbo.GetMatches #input = '101,104';

Answer 2

If you need help, explanations, let me know :)
DECLARE
#input VARCHAR(MAX) = '101,104',
#separator CHAR(1) =',',
#separatorPosition INT,
#value VARCHAR(MAX),
#start INT = 1
DECLARE #split_input TABLE(Value VARCHAR(MAX))
DECLARE #tmp TABLE (st VARCHAR(50))
INSERT INTO #tmp VALUES ('101,102,103')
INSERT INTO #tmp VALUES ('103,104,105')
INSERT INTO #tmp VALUES ('106,107,108')
SET #separatorPosition = CHARINDEX(#separator, #input)
IF #separatorPosition = 0
BEGIN
INSERT INTO #split_input
VALUES
(
#input
)
RETURN
END
SET #input = #input + #separator
WHILE #separatorPosition > 0
BEGIN
SET #value = SUBSTRING(#input, #start, #separatorPosition - #start)
IF (#value <> '')
INSERT INTO #split_input
VALUES
(
#value
)
SET #start = #separatorPosition + 1
SET #separatorPosition = CHARINDEX(#separator, #input, #start)
END
SELECT tmp.st FROM #tmp AS tmp INNER JOIN #split_input AS split ON tmp.st LIKE '%' + split.Value + '%'

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE FUNCTION [dbo].[fnParseArray] (#Array VARCHAR(MAX),#separator CHAR(1))
RETURNS #T Table (col1 varchar(50))
AS
BEGIN
-- #Array is the array we wish to parse
-- #Separator is the separator charactor such as a comma
DECLARE #separator_position INT -- This is used to locate each separator character
DECLARE #array_value VARCHAR(MAX) -- this holds each array value as it is returned
-- For my loop to work I need an extra separator at the end. I always look to the
-- left of the separator character for each array value
SET #array = #array + #separator
-- Loop through the string searching for separtor characters
WHILE PATINDEX('%' + #separator + '%', #array) <> 0
BEGIN
-- patindex matches the a pattern against a string
SELECT #separator_position = PATINDEX('%' + #separator + '%',#array)
SELECT #array_value = LEFT(#array, #separator_position - 1)
-- This is where you process the values passed.
INSERT into #T VALUES (#array_value)
-- Replace this select statement with your processing
-- #array_value holds the value of this element of the array
-- This replaces what we just processed with and empty string
SELECT #array = STUFF(#array, 1, #separator_position, '')
END
RETURN
END
