WPF 开发备忘录

运营日：

select t.*
   from (select ab.*, bs.station_cn_name, bd.device_name
           from audit_tvm_cash_detail ab
           left join basi_station_info bs
             on ab.station_id = bs.station_id
           left join basi_dev_info bd
             on ab.device_id = bd.device_id
          where bd.device_type = '02') t, report_requirement_info r
  where t.run_date = r.run_date
  order by t.station_id,
           t.device_id,
           t.run_date,
           t.audit_date,
           t.audit_time)

;f:datetime -时间日期格式

;f:fen            -表示单价分

在查询结果后面增加一行自定义数据

union all

select distinct ' ' as name, a from v

instr(字段,'关键字')>0

例如 like %关键字%   等同于  instr(字段,'关键字')>0 

ComboBox 静态值绑定
