查詢team_lvl最大的一條數據

select * from (select distinct t.team_id as teamId,t.team_name as orgName,t.team_lvl as teamLvl 
from t02salesinfo_backup s,t01teaminfo_backup t
where s.sales_code=#{agentCode} and trim(s.channel_id)=#{channelId} and s.channel_id=t.channel_id 
and t.year_month=s.year_month and trim(t.stat)=1 and s.year_month=#{month}   and s.sales_id=t.leader_id
order by t.team_lvl desc)where rownum=1

查詢該表中的全部字段名和數據類型   注意:表名必定要大寫!

select A.COLUMN_NAME,A.DATA_TYPE from user_tab_columns A
where TABLE_NAME='T01TEAMINFO'
