UPDATE FROM

Hi all,

in the documentation for the UPDATE SQL statement, no FROM clause is allowed, however in the Examples section is written

UPDATE T SET VAL = T2.VAR FROM T, T2 WHERE T.KEY = T2.KEY;

which violates the syntax. Can please someone write down the correct UPDATE normal form? It seems that some forms of FROM are allowed, but then again some of them throw exotic runtime errors.

Cheers,
