That's right approach, in common.
The first question should be raised is "Why you want to use SQL database?"
May be to speed up lookups. It implies some technology, namely indexing.
But indexing has its own limitations, and is almost incompatible with
regex-like lookups. So you have to look for some algorithmic combinations
of different lookup types, to achieve speedup and limit complexity of code.
