The compute by list does not match the order by list.

Error Message:
Msg 163, Level 15, State 1, Line 1
The compute by list does not match the order by list.

Severity level:
15.

Description:
This error message appears when you try to use ORDER BY and COMPUTE BY lists that are not identical.

Consequences:
The T-SQL statement can be parsed, but causes the error at runtime.

Resolution:
Errors of the Severity Level 15 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. The ORDER BY and the COMPUTE BY lists must be identical.

Versions:
All versions of SQL Server.

Example(s):
USE Northwind;
GO
SELECT EmployeeID, OrderDate, Freight
FROM Northwind.dbo.Orders
ORDER BY EmployeeID, OrderDate
COMPUTE SUM(Freight) BY EmployeeID,  CustomerID

Remarks:
In SQL Server 2005 COMPUTE BY is only maintained for backwards compatibility reasons. Microsoft recommends to use Analysis Services or the ROLLUP operator instead.
