1 つのエステートを持つ人を見つけることができます:
SELECT FNR FROM agare,users WHERE FNR IN (SELECT FNR FROM fastighet, users WHERE FNR=username AND adress IS NULL GROUP BY FNR HAVING COUNT(FNR) < 2) AND users.username=FNR GROUP BY FNR
魔女は、住所欄が空白の多くの人々のリストを返します
しかし、users の空白のアドレス フィールドに fastighet のデータを入力したいと考えています。
使用しようとしましINSERT into users (adress) SELECT "something"たが、助けが必要です
