1、创建表

create table LIB
(
  BILL_MONTH VARCHAR2(10),
  AREA_CODE  VARCHAR2(8),
  NET_TYPE   CHAR(1),
  LOCAL_FARE NUMBER(10,2)
)

2、插入数据

insert into LIB (BILL_MONTH, AREA_CODE, NET_TYPE, LOCAL_FARE)
values ('200405', '5761', 'G', 7393344.04);
insert into LIB (BILL_MONTH, AREA_CODE, NET_TYPE, LOCAL_FARE)
