You can however, join the two tables.

UPDATE  globale2 g
        INNER JOIN globale gg
            ON g.neng = gg.neng
SET     g.nita = gg.nita,
        g.tita = gg.tita,
        g.notaita = gg.notaita
WHERE   g.nita IS NULL
        AND gg.uris = 'mma' 
        AND gg.nita IS NOT NULL

assume there is a table A_temp, with two columns 'one' and 'two'. TABLE A_temp

1       2

The query

UPDATE (SELECT * FROM A_temp ) A SET one = A.two where one = '1'

updates the table as

2      2
