我想包括dname,deptno,loc,加上ename並將colum標記爲Number_of_People總計薪水標記Colum Total Salary然後加入部門表,我只想爲部門30查詢時出現問題
繼承人的錯誤我得到
SQL> select dname,deptno, loc, count(ename) as Number_of_People, sum(sal) as Total_Salary from emp join dept on emp.deptno = dept.deptno group by dname,loc where deptno =30;
select dname,deptno, loc, count(ename) as Number_of_People, sum(sal) as Total_Salary from emp join dept on emp.deptno = dept.deptno group by dname,loc where deptno =30

我得到一個錯誤,當我按照你擁有的方式運行。第1行出現錯誤:ORA-00918:不明確定義的列 - – user770022
在這種情況下,'emp'和'dept'中定義了'dname','deptno'或'loc'之一。選擇你想要的那一個(例如,如果它是重複的'dname',選擇你想要'emp.dname'還是'dept.dname')。 – 2011-09-15 02:23:45
我已經發布了這兩個表 – user770022
