Hi,

I'm using sqlite. I have 2 tables. One is a detail table. I want to select all the records in table 1 only if they have details in table 2 where the column "type" equals "List"

select * from Vehicles

having

select count > 0 from list_detail where type = "List"

Any help would be greatly appreciated.

I think you want something like this; I'm not familiar with sqlite but hopefully it allows standard syntax.
select * 
from Vehicles
where exists
 (select * from list_detail 
where type="list" 
and some_other_column = Vehicles.some_other_column)

Open in new window

You'll need to change "some_other_column" to the name of the columns used to join the two tables; you didn't specify that in your question.
