Обсуждение: Selecting Varchar range.
Dear PostgreSQL people,
I didn't find this in the archives or the idocs, so...
How does one select a varchar range? The meaning of my question is
best illustrated by the following completely hypothetical and totally
imaginary situation:
Let's say I have a table of musical artists:
CREATE TABLE Artists (
Id SERIAL PRIMARY KEY,
Name VARCHAR(100)
);
And I want to eventually display only the artists from 'Aa' to 'Am'.
Naturally doing a select where Name like 'A%' will not return me what I
want.
Any ides on how to do this? [Will "SELECT Name FROM Artists WHERE
Name > 'Aa%' AND Name < 'Am%';" work?]
Bonus question: How do I select artists whose names start with a
number?
I'd appreciate any help. Thanks! :)
Sincerely,
Daryl.
