Question

Select * From tableA, TableB INNER JOIN tableC ON TableB.X = tableC.Y  ==>OK

Select * From tableA, TableB LEFT JOIN tableC ON TableB.X = tableC.Y   ==>ERROR

我将“ LEFT JOIN”替换为“ INNER JOIN” =>错误

Answer 1

他得到的错误是JOIN Expression not supported。

@VanThuyet： 您必须通过子查询提供联接：

Select * From tableA, (Select * From TableB LEFT JOIN tableC ON TableB.X = tableC.Y) As BC
