Question

I have a sqlite3 query like:

SELECT word FROM table WHERE word NOT LIKE '%a%';

This would select all of the words where ‘a’ does not occur in the word. This I can get to work perfectly. The problem is if I want to further restrict the results to not include ‘b’ anywhere in the word. I am picturing something like this.

SELECT word FROM table WHERE word NOT IN ('%a%', '%b%', '%z%');

which this obviously does not work, but this is the idea. Just adding an AND clause is what I’m trying to avoid:

SELECT word FROM table WHERE word NOT LIKE '%a%' AND NOT LIKE '%b%';

If this is the only option then I will have to work with that, but I was hoping for something else.

If you use Sqlite’s REGEXP support ( see the answer at Problem with regexp python and sqlite for how to do that ) , then you can do it easily in one clause:

SELECT word FROM table WHERE word NOT REGEXP '[abc]';
