How to check if a string contains numbers

There are number of ways in SQL Server to check if a string has numbers in it. In one of the previous articles, we saw how to Extract Numbers from a String using Sql Server 2005

I recently got a comment on that article from a sqlservercurry.com visitor who asked me to find out if a string has numbers, using PatIndex. Here's how to do so using PatIndex :

DECLARE @str1 varchar(15)
SET @str1 = 'abcde99jtk'

-- Check if PatIndex returns a value > 0. If yes, the string has numbers
-- If the value is 0, the string does not have numbers
IF PATINDEX('%[0-9]%',@str1) > 0
PRINT 'YES, The string has numbers'
ELSE
PRINT 'NO, The string does not have numbers'
