# 3184 Using IN Operator with Sub-Query Containing Only Aggregate Function Causes Error

The following query produces the error:

ElevateDB Error #700 An error was found in the statement at line 0 and column 0 (Invalid expression "MIN of Id" found, ORDER BY clause not allowed)

DELETE FROM Table WHERE Id NOT IN
(SELECT DeleteId FROM (SELECT min(Id) AS DeleteId FROM Table
GROUP BY Field1,Field2) t1)

Comments

The problem was caused by an internal rewrite of the ORDER BY clause done by the query compiler in order to speed up the IN operation.

Resolution

Fixed Problem on 4/14/2010 in version 2.03 build 10
