我可以在SQL Server数据库上使用LIMIT N，M吗? [英] Can I use LIMIT N,M on SQL Server database

问题描述

我有以下SQL语句:

SELECT [id], [name]
FROM [dbo.test_db_002] t1
LEFT JOIN [dbo.test_db_003] t2 ON t1.[id] = t2.[itmid]
ORDER BY t2.[iid] ASC;

这似乎很简单，但我无法弄清楚.我需要在其中添加LIMIT N,M，以从第N个中检索M个项目，但是在'limit'字周围，我不断出错.我尝试将LIMIT子句放在上面的sql语句中的任何地方，但无济于事.

This seems very simple, but I can't figure it out. I need to add LIMIT N,M to it to retrieve M items from the N'th one, but I keep getting errors around 'limit' word. I tried putting that LIMIT clause everywhere I could inside the sql statement above with no avail.

PS.我正在写VS2010附带的SQL Server.

推荐答案

要回答您的查询，您可能需要:(取决于M和N的值)

To answer for your query, you may want: (depending on your values for M and N)

WITH cte AS
(
   SELECT [id], [name], ROW_NUMBER() OVER (ORDER BY t2.[iid] ASC) AS rowNumber
   FROM [dbo.test_db_002] t1
   LEFT JOIN [dbo.test_db_003] t2 ON t1.[id] = t2.[itmid]
)
SELECT [id], [name]
FROM cte
WHERE rowNumber BETWEEN 3 AND 5

需要注意的是，两者之间的值是BETWEEN N AND N + M

Something to watch out for, the values in the between are BETWEEN N AND N + M

此外，这是一个链接，其中包含有关公用表表达式的信息是我使用的WITH cte语法.

Also, here's a link with information about Common Table Expressions which is the WITH cte syntax I used.
