A COMPUTE BY item was not found in the order by list. All expressions in the compute by list must also be present in the order by list.

Error Message:
Msg 143, Level 15, State 1, Line 1
A COMPUTE BY item was not found in the order by list. All expressions in the compute by list must also be present in the order by list.

Severity level:
15.

Description:
This error message appears when you try to use an element in the ORDER BY list that does not appear also in the COMPUTE BY list.

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 are corrigible by the user. The statement cannot be executed this way. The list used in the ORDER BY and COMPUTE clauses must be identical.

Versions:
All versions of SQL Server.

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

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.
