Filtering with Where
A select without any filter returns every row in the table. To narrow down
results, add a where clause:
select * from main.users where id = 2;
This returns only the row where id equals 2. You can use the usual
comparison operators - =, !=, <, <=, >, >=:
select * from main.users where id >= 2;
That returns Bob and Charlie, since both have an id of 2 or higher.
You can also filter on non-key fields:
select id from main.users where name = "Alice";
