SELECT SUBSTRING(val, PATINDEX('%[0-9]%', val), PATINDEX('%[0-9]|%', val) - PATINDEX('%[0-9]%', val) + 1) FROM yourTable; Demo Data: CONV (N,from_base,to_base) Converts numbers between different number bases. Guidance to add this requirement: If there is no number, then PATINDEX ('% [0-9]%',txt) will be 0 * The first solution above will return error in that case, therefore you can first check if there is a number or not using CASE statement for example.
