mysql的查询语句的排序问题
SQL查询语句如下:
select * from table where (ID = 10) or (ID = 32) or (ID = 22) or (ID = 76) or (ID = 13) or (ID = 44)
我想让结果按10,32,22,76,13,44的顺序检索出来,但是检索后的顺序变成了按ID排序的:10,13,22,32,44,76。
请问如何让结果不排序呢???
多谢!
一个变通的方法
-
SQL code
select *, case id when 10 then 1 when 32 then 2 when 22 then 3 when 76 then 4 when 13 then 5 when 44 then 6 END as seq from table where (ID = 10) or (ID = 32) or (ID = 22) or (ID = 76) or (ID = 13) or (ID = 44) order by seq
-
SQL code
select *, INSTR(',10,32,22,76,13,44,', ','+id+',') as seq from table where id in(10,32,22,76,13,44) order by seq
探讨
SQL codeselect *,
INSTR(',10,32,22,76,13,44,', ','+id+',') as seq
from table
where id in(10,32,22,76,13,44)
order by seq

哈哈哈哈哈哈哈,你们都不行,看我的。
select *
from table
where id in(10,32,22,76,13,44)
order by field (id,10,32,22,76,13,44);
select a.*, a.mark from
(
select table.id, 600 as mark from table where table.id=10 union
select table.id, 500 as mark from table where table.id=32 union
select table.id, 400 as mark from table where table.id=22 union
select table.id, 300 as mark from table where table.id=76 union
select table.id, 200 as mark from table where table.id=13 union
select table.id, 100 as mark from table where table.id=44
) as a order by mark desc;
