我收到错误

  

字段列表中的列expeertID不明确

我不确定如何解决此问题

INSERT INTO cv(expertID)
SELECT expertID 
FROM experts
INNER JOIN cv ON experts.expertID = cv.expertID;

Answer 1

尝试以下操作-由于两个表中都存在tablename，因此您需要添加expertID column

INSERT INTO cv(expertID)
SELECT experts.expertID 
FROM experts
INNER JOIN cv ON experts.expertID = cv.expertID;

Answer 2

您需要将column name与tablename指定要从哪个表中显示，或者指定insert所需的数据：

INSERT INTO cv(expertID)
     SELECT e.expertID 
     FROM experts e INNER JOIN 
          cv 
          ON e.expertID = cv.expertID;

Answer 3

尝试一下！

我使用了表别名，然后在选择列表中用列明确提到了别名。现在，select中的expertID来自experts表，而不是模棱两可的。

INSERT INTO cv(expertID)
SELECT e.expertID 
FROM experts e
INNER JOIN cv  c ON e .expertID = c.expertID;
