mysql按顺序获取某些行

Question

How can I get certain rows from a table in order?如何按顺序从表中获取某些行？ For Example I have the following rows:例如，我有以下几行：

EmpID   Name
81      Albert
22      Ashley
71      John
42      Jack
55      Bob

Primary Key is EmpID.主键是 EmpID。 I want to get only: John, Albert, Bob IN ORDER.我只想得到：John、Albert、Bob 按顺序。 Result should be:结果应该是：

71      John
81      Albert
55      Bob

How can I do that using MySQL query?我怎样才能使用 MySQL 查询做到这一点？ Thanks heaps !谢谢堆！

Answer 1

Try this one, it use custom sort试试这个，它使用自定义排序

SELECT *
FROM TABLENAME
WHERE EmpID IN (72,81,55)
ORDER BY FIELD(NAME, 'John', 'Albert', 'Bob')

Answer 2

Put this at the end of your SQL statement:把它放在你的 SQL 语句的末尾：

ORDER BY CASE EmpID
    WHEN 71 THEN 1  
    WHEN 81 THEN 2  
    WHEN 55 THEN 3  
    ELSE 4
END
