Hi
How can I get query results in the same order i have given using
'in' express
for example
select col_1,col_2 from table_1
where col_1 in(5,1,3,8,2)
select col_1,col_2 from table_1
where col_1 in(1,3,5,4)
The result should display according the order i have given 'in' order
like
col_1
--------
5
1
3
8
2
Is there any way
Thanks

Hi,
how it is showing output right now ?
April 9, 2010 at 5:31 am
-- Method 1
DROP TABLE #InList
CREATE TABLE #InList (RowID INT IDENTITY(1,1) NOT NULL, JoinValue INT)
INSERT INTO #InList (JoinValue)
SELECT 5 UNION ALL
SELECT 1 UNION ALL
SELECT 3 UNION ALL
SELECT 8 UNION ALL
SELECT 2
-- NOTE - the sequence will fail if UNION is used instead of UNION ALL
-- because UNION eliminates dupes; the processing reorders the input set.
SELECT col_1,col_2
FROM table_1 t
INNER JOIN #InList i
ON i.JoinValue = t.col_1
ORDER BY i.RowID
-- Method 2
SELECT col_1,col_2
FROM table_1
WHERE col_1 IN (5,1,3,8,2)
ORDER BY CASE col_1
WHEN 5 THEN 1
WHEN 1 THEN 2
WHEN 3 THEN 3
WHEN 8 THEN 4
WHEN 2 THEN 5 END

Padmaja.
Create a tabular function
which takes input VACHAR(1000)
Returns Table (id identity(1,1),FindNo int)
Write a code to insert the comma seperated string into the table
SELECT * FROM fn_gettblOrder('5,1,3,8,2')
id FIndNo
1 5
2 1
3 3
4 8
5 2
Now u can use Ur query with JOin of this Function....
select Col_1,Col_2 from @table
JOIN (SELECT id,findNo FROM fn_gettblOrder('5,1,3,8,2')) Ftbl on Ftbl.findNo=Col_1
where Col_1 in(5,1,3,8,2) order by id ASC
U may get the O/p what u expected.....& Use this same function where u need to get table from CSV values....
:-):-)
Thanks!

Create a tabular function...
Or better still use one of Chris' methods or:
DECLARE @Example
TABLE (
col1 INTEGER NOT NULL PRIMARY KEY,
col2 VARCHAR(10) NOT NULL
);
INSERT @Example
(col1, col2)
SELECT 1, 'One' UNION ALL
SELECT 2, 'Two' UNION ALL
SELECT 3, 'Three' UNION ALL
SELECT 4, 'Four' UNION ALL
SELECT 5, 'Five' UNION ALL
SELECT 6, 'Six' UNION ALL
SELECT 7, 'Seven' UNION ALL
SELECT 8, 'Eight';
SELECT col1, col2
FROM @Example
WHERE col1 IN (5,1,3,8,2)
ORDER BY
CHARINDEX
(
',' + CONVERT(VARCHAR(12), col1) + ',',
',' + '5,1,3,8,2' +','
) ASC;
