ORACLE SQL缺少右括號差語法

Question

我似乎無法弄清楚語法錯誤在哪裏。儘管查詢非常簡單。

在此先感謝！

UPDATE t_stock 
set f_atcid = (select a.id from t_atc a where a.f_code = ' ' where rownum < 2) 
where id in (select f_stockid from t_barcode where f_barcode = ' '); 

Answer 1

問題是兩個where子句。更改第二個爲and：

UPDATE t_stock 
    set f_atcid = (select a.id 
        from t_atc a 
        where a.f_code = ' ' and 
----------------------------------------^ 
         rownum < 2 
       ) 
where id in (select f_stockid from t_barcode where f_barcode = ' ');
