Question

I need a regex to match this pattern:

• A string 13 characters long
• The first letter must be a L, H, or B (not case sensitive)
• The next 12 characters must be in the range 0-9

e.g. L109878762013 will match while L10/987876/2013 won’t

If the pattern doesn’t match any of the above criteria, and isn’t 13 characters long then it shouldn’t be picked up.

What do I need to modify in the regex [LHB][0-9]{12} to make it work?

Answer 1

Should work if you expand the {12}, which SQL server does not support:

LIKE '[LHB][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9][0-9]'
