city_name是字段名，現在要按("北京","上海","廣州") 先後順序把數據查詢統計出來？不知道你什麼數據庫, 假如是 Oracle:
select
count(city_name),
city_name
from
tuan_info
where
source_type = 1
and city_name in("北京","上海","廣州")
group by
city_name
ORDER BY
INSTR('北京,上海,廣州', city_name);
如果是 SQL Server 用
ORDER BY CHARINDEX(city_name, '北京,上海,廣州')追問
是SQL Server 的，怎麼寫哦，給個完整點的語句好嗎
回答
select
count(city_name),
city_name
from
tuan_info
where
source_type = 1
and city_name in("北京","上海","廣州")
group by
city_name
ORDER BY CHARINDEX(city_name, '北京,上海,廣州')
前面的SQL都是一樣的啊。
只是 增加一個 ORDER BY 的排序處理。追問
在嗎，不行的，提示有錯啊，是什麼問題哦
[SQL] select count(city_name), city_name from tuan_info where source_type = 1 and city_name in("北京","上海","廣州") group by city_name ORDER BY CHARINDEX(city_name, '北京,上海,廣州');
[Err] 1305 - FUNCTION data_group.CHARINDEX does not exist回答
你這個是什麼數據庫啊？ CHARINDEX 是 SQL Server 自帶的函數啊。
追問
那個，，是MYSQL的哦，怎辦
回答
MySQL 就換一個函數 INSTR
select
count(city_name),
city_name
from
tuan_info
where
source_type = 1
and city_name in("北京","上海","廣州")
group by
city_name
ORDER BY INSTR( '北京,上海,廣州', city_name)
