Can someone help. I have a table with an outcome column of:

4.8.1
6.4.1.1
6.4.1.1
5.1.7
5.1.7
23.35.4.5

How do I select those numbers which are less than 6.1?

Thanks

Hello crazyco,

Perhaps something like this would stimulate some thought?

SELECT 
	[output],p
FROM
(
	SELECT [output], CAST(PARSENAME(REVERSE(output),1) + '.' + PARSENAME(REVERSE(output),2) AS NUMERIC(10,2)) AS p
	FROM @table
) d
WHERE d.p < 6.1

HTH.

Thank you, it turns out I misinterpreted the question anyway so this wasn't even required, but thank you anyway as its good for me to keep note of these things.

damn!


DECLARE @foo TABLE (
	[val] VARCHAR(20)
	)
INSERT @foo ([val])
VALUES ('4.8.1')
	 , ('6.4.1.1')
	 , ('6.4.1.1')
	 , ('5.1.7')
	 , ('5.1.7')
	 , ('23.35.4.5')
	 , ('6.11')
	 , ('6')
	 , ('6.1')
	 , ('FOOBARRED')

SELECT *, CHARINDEX('.', [val], 0) FROM @foo

SELECT * FROM @foo
WHERE
    [val] < '6.100000001'
AND CHARINDEX('.', [val], 0) <= 2
