# 2287 Correlated Sub-Queries Not Supported in SELECT Column Expressions

The DBISAM Migration Guide states that EDB supports scalar subqueries in the select list:

"ElevateDB supports single-row query expressions as values in the list of selected columns."

I'm not sure if this is an issue with build 1 or you've postponed the functionality to a future point release, but the following query throws the following error:

ElevateDB Error #700 An error was found in the statement at line 5 and column 5 (Invalid expression select found, query expression not allowed)

select
 EmployeeID,
 FirstName||' '||LastName as Name,
 (
   select count(OrderID)
   from Orders
   where EmployeeID = Employees.EmployeeID
 ) as OrderCount
from Employees
