Derived table ‘%.*ls’ is not updatable because it contains aggregates, or a DISTINCT or GROUP BY clause, or PIVOT or UNPIVOT operator.

Error Message:
Msg 4418, Level 16, State 1, Line 5
Derived table ‘%.*ls’ is not updatable because it contains aggregates, or a DISTINCT or GROUP BY clause, or PIVOT or UNPIVOT operator.

Severity level:
16.

Description:
This error message appears when you try to update a derived table that contains one of the in the message text mentioned syntax constructs.

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

Resolution:
Errors of the Severity Level 16 are generated by the user and can be fixed by the SQL Server user. The statement cannot be executed this way. You cannot update a derived table that contains one of these syntax constructs.

Versions:
All versions of SQL Server.

Example(s):
IF OBJECT_ID (‘dbo.t’) IS NOT NULL
    DROP TABLE dbo.t;
GO
CREATE TABLE dbo.t
(
    c1 int
);
UPDATE t
    SET
    c1 = 2
FROM
    (SELECT DISTINCT
        c1
    FROM
        dbo.t) t

Remarks:
In the above example we try to update the derived table t. Because the derived table contains the DISTINCT keyword, the error is raised.
