Question

this subquery works in SQL Server:

select systemUsers.name,      (select count(id)       from userIncidences       where idUser = systemUsers.id )  from systemUsers 

How can It be made in SQL Compact?

Thanks!

Try this:

SELECT su.Name, COUNT(ui.ID) FROM systemUsers su LEFT JOIN userIncidences ui ON ui.idUser = su.ID GROUP BY su.Name 

[Edit:]
I originally had an INNER JOIN just like Tomalak, but I realized that this would exclude users with no incidents, rather than show them with a 0 count. That might even be what you want, but it doesn’t match your original.
