Question

I am trying to run this query

    SELECT        Name, Position, Salary
FROM            Employee
WHERE        (Salary =
                             (SELECT        MAX(Salary)
                               FROM            Employee))

However whenever I run it I get the following error

Error Source: SQL Server Compact ADO.NET Data Provider
Error Message: There was an error parsing the query. [Token line
number = 1, Token line offset = 69, Token in error = SELECT]

I’m wondering if this is me not undertsanding how subqueries work although my tutor assures me that the statement I am trying to run is correct, could anyone shed some light on this situation, thanks.

Answer 1

This should work for SQL Server:

SELECT Name, Position, Salary
FROM Employee E
   JOIN ( SELECT Max(Salary) as Sal FROM Employee ) M  ON E.Salary = M.Sal

Here is the SQL Fiddle.

–EDIT

It sounds like you are using SQL Server CE which does not fully support nested sub queries. Try something like this instead using the IN keyword:

SELECT e.Name, e.Position, e.Salary
FROM Employee e
WHERE e.Salary IN (SELECT MAX(Salary) as sal 
                   FROM Employee)
