Do you mean a substring, or is a number greater than or equal to a specified values? – Rowland Shaw Apr 01 '10 at 07:34

I thought square brackets escaped in MSSQL, such as `LIKE '[_]'`? Also out of interest where did you find this information? – Paul C Jan 08 '13 at 10:00

1No this does work, I've been doing it for years and have no idea where I first saw it... – cjk Jan 08 '13 at 13:25

1@CodeBlend square brackets are used for escaping when *outside* a string, and for delimiting patterns when *inside* a string. – Ian Kemp Feb 26 '14 at 13:32

2The square brackets in a LIKE statement are explained here. https://msdn.microsoft.com/en-us/library/ms179859.aspx?f=255&MSPPError=-2147217396 – NTDLS Oct 22 '15 at 18:23

Note that you must use [0-9] as shown and not the Regex shorthand [\d] for digit. Worked for me - up vote. – Yogi Feb 23 '18 at 17:28

DECLARE @str AS VARCHAR(50)
SET @str = 'PONIES!!...pon1es!!...p0n1es!!'
IF PATINDEX('%[0-9]%', @str) > 0
PRINT 'YES, The string has numbers'
ELSE
PRINT 'NO, The string does not have numbers'

The simplest method is to use LIKE
:
SELECT CASE WHEN 'FDAJLK' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END; -- False
SELECT CASE WHEN 'FDAJ1K' LIKE '%[0-9]%' THEN 'True' ELSE 'False' END; -- True

- You could use CLR based UDFs or do a CONTAINS query using all the digits on the search column.
