Question

我有两个表 - 项目和订单。

Item  
=====================
ID, ItemName 


Order 
========================
orderID, ID , status

我想使用内部联接加入表：

SELECT Order.orderID, Order.ID, Item.ItemName
FROM Order
INNER JOIN Item
ON Order.ID=Item.ID

但问题是我需要在php上进行分页。

我有代码，但我不知道如何修改它，因为我的sql不是很好。

这是代码（我已经修改了它，并且能够显示'*'，但不知道如何在下面的代码中应用内连接）：

SELECT TOP 20 * FROM 
(
SELECT  ROW_NUMBER() OVER (ORDER BY Order.orderID) AS RowNumber, *, TotalRows=Count(*) OVER()
FROM Order WHERE status=1
) _tmpInlineView
WHERE RowNumber >= 20 AND status=1 ORDER BY Order.orderID

提前致谢。

Answer 1

将您的联接放在订单表下面：

SELECT TOP 20 * FROM 
(
SELECT  ROW_NUMBER() OVER (ORDER BY Order.orderID) AS RowNumber, Order.orderID, Order.ID, Item.ItemName, TotalRows=Count(*) OVER()
FROM Order INNER JOIN Item
ON Order.ID=Item.ID WHERE status=1
) _tmpInlineView
WHERE RowNumber >= 20 ORDER BY _tmpInlineView.orderID

Answer 2

试试这个

      SELECT TOP 20 * FROM 
        (
        SELECT  ROW_NUMBER() OVER (ORDER BY Order.orderID) AS RowNumber, ORDER.*, 
Count(1) OVER() as TotalRows
        FROM ORDER INNER JOIN Item ON Order.ID=Item.ID
         WHERE status=1
        ) _tmpInlineView
        WHERE RowNumber >= 20 ORDER BY orderID

或试试这个

    SELECT * 
    FROM ORDER INNER JOIN Item ON Order.ID=Item.ID WHERE status=1
    ORDER BY Order.orderID 
    OFFSET ( @PageNo - 1 ) * @RecordsPerPage ROWS
    FETCH NEXT @RecordsPerPage ROWS ONLY

The following are the limitations of using Offset Fetch:
1) Fetch Next can't be used standalone, it requires Offset
2) Offset can't be used standalone, it requires order by
3) Top can't be combined with offset fetch next in the same query expression
