Hello List, Is there an IS_NUMERIC(aCandidateString) function in MySQL that I can run in a query, similar to the various PHP "is_*" functions? I can't seem to find it in the docs (other than a C API IS_NUM macro). I have a field in a database with serial numbers like: ...1234 ...1235 ...1236-A ...1237B and I want to get the last 4 characters of the numeric substring like so: 1234 1235 1236 1237 I should be able to do it in 1 SQL query if there is an IS_NUMERIC equivalent, or else I will probably write a PHP script.
