使用mysql选择最新的10件事 - Select top 10 most recent things using mysql

Select top 10 most recent things using mysql

本文关键字：10件事最新选择 mysql 使用 | 更新日期: 2023-09-27

我希望提交最新的十个补丁（前十个补丁ID desc）从下面的查询开始，我在10上得到一个错误。错误为syntax error, unexpected NUM, expecting END_OF_INPUT, or ';'。是否会导致以下查询中出现此错误？

SELECT TOP 10 synth.*
FROM (
    SELECT p.`id`, 
        p.`patchName`,
        p.`description`,
        p.`tfsID`,
        p.`codeRelease`,
        s.`name`, 
        d.`deployStatus`, 
        d.`deployedDate`,
        t.`testedStatus`,
        t.`testedDate`
    FROM `patches` AS p 
    JOIN `deployed` AS d ON p.`id` = d.`PatchID`
    JOIN `servers` AS s ON d.`serverID` = s.`id`
    JOIN `tested` AS t ON p.`id` = t.`patchID`
) synth
ORDER BY synth.id DESC

TOP 10是MS SQL特有的东西，在MySQL中他们使用LIMIT。

SELECT p.`id`, 
    p.`patchName`,
    p.`description`,
    p.`tfsID`,
    p.`codeRelease`,
    s.`name`, 
    d.`deployStatus`, 
    d.`deployedDate`,
    t.`testedStatus`,
    t.`testedDate`
FROM `patches` AS p 
JOIN `deployed` AS d ON p.`id` = d.`PatchID`
JOIN `servers` AS s ON d.`serverID` = s.`id`
JOIN `tested` AS t ON p.`id` = t.`patchID`
ORDER BY p.`id` DESC
LIMIT 10

限制的语法在每台服务器上都有很大的不同，这里有一个概述：

从显示10个结果的行100开始（即101102103…）

PostgreSQL, MySQL and DB2: SELECT * FROM table LIMIT 10 OFFSET 100
Informix: SELECT SKIP 100 FIRST 10 FROM table 
Microsoft SQL Server and Access: SELECT TOP 10 * FROM table -- skipping the offset here as it's a pain, search for it if you need it :)
Oracle: SELECT * FROM (SELECT *, ROW_NUMBER() OVER ORDER BY id) rnk FROM table) WHERE rnk BETWEEN 100 AND 110
