mysql - 如果表1有共同点，如何将数据插入到表2？

Question

我在MYSQL的同一个数据库中有2个表，我想将table1中的columnA插入到table2中的columnA，我的条件是table1.name是否等于table2.name。我尝试过，但没有成功

INSERT INTO Table2 (solId, openTime, closingTime, guid)  
SELECT solId, openTime, closingTime, guid
FROM Table1
WHERE Table2.name = Table1.name;

您可能需要更新:

update table2 t2 join
       table1 t1
       on t1.name = t2.name
    set t2.solId = t1.solId,
        t2.openTime = t1.openTime,
        t2.closingTime = t1.closingTime,
        t2.guid = t1.guid;
