Question

What would be the most efficient way to check for numbers in a field that would contain a few letters? I would like to do this if the where statement as possible.

The data would look something like this:

3833N4323
32N907654
5W5840904

Answer 1

Checking for at least one number in a field (corrected):

WHERE PATINDEX('%[0-9]%', field) != 0

Checking for only numbers in a field:

WHERE TRY_CONVERT(field AS int) IS NOT NULL
