我在此要求:
页: 1 在<编码>表格中各行各有一定数目的行文,载有订单的说明。 <代码>id栏作为外在钥匙。
我想得到的是每项命令的所有细节(细节见<条码>栏目,包括<条码>id)。 http://www.un.org/Depts/DGACM/index_chinese.htm
问题在于,它限制<条码> 字典> 字体 浏览量,而不是限制<条码>> 字码>。
我如何能够取得预期的效果?

<>关于将记录数目限制在2:

SELECT OC.*, O.* FROM OrderContents OC
INNER JOIN (SELECT *
FROM Orders
ORDER BY ID
LIMIT 2) O ON O.ID=OC.ID
