查询sql server中的工作，但不在MySql中查询

Question

我希望从订单表中获得第一排。以下查询在sql server中有效：

select top 1(OrderID)
from dbo.Orders
order by OrderID desc 

但它在MySql中不起作用 - 应该如何为MySql编写？

Answer 1

对于MySQL使用LIMIT

的MySQL

select OrderID
from dbo.Orders
order by OrderID desc 
LIMIT 1;

SQL Server

select top (1) OrderID
from dbo.Orders
order by OrderID desc 

Answer 2

SELECT OrderID FROM dbo.Orders
ORDER BY OrderID desc 
LIMIT 1;
