ORA-00903：无效的表名

Question

I have the following database table:

CREATE TABLE pontaje
    (
    coda        NUMBER(4) REFERENCES angajati( coda ),
    data        DATE,           
    ore         NUMBER(3)   
    );

When I run the code :

SELECT coda, SUM(ore) AS totalore
FROM   pontaje,
GROUP BY coda

I get ORA-00903: invalid table name .

But I know the table exists because: SELECT * FROM pontaje works.

Answer 1

删除表名后面的逗号。

Answer 2

SELECT coda, SUM(ore) AS totalore
FROM pontaje                       -- << remove comma
GROUP BY coda
