Question

I “inherited” a db with a field in a table where there are lowercase and uppercase mixed together, eg.

gateway 71, HOWARD BLVD, Chispa, NY

They aren’t easily “splittable” with code because they don’t always come in this form. What I need is a way to extract only uppercase letters. Is this possible with SQLite?

Answer 1

This is a case where it may just be easier (and perhaps quicker) to SELECT with any additional WHERE requirements you may have and create a cursor to iterate over the results doing your uppercase checks in code.

Another option with SQLite would be to create a custom function, so you could do something like:

SELECT foo WHERE MYISALLUPPERFUNC(foo) = 1;
