需求；连续3个月未申报(GL_WSBXX表,SBBZ申报标志，Y为已申报，N为未申报)。申报时间的列是SBRQ
即要查询GL_WSBXX表中SBRQ连续3个月SBBZ为N的信息。
就是查询连续3个月的数据？
是每月一条记录吗？
一条sql语句可以搞定
求指教，是一个月一条
测试数据贴上来
贴数据不可能的呵呵，SBRQ是date类型
SQL code:
--建表(其中id为单位ID)
create table GL_WSBXX(id number,sbrq date,sbbz varchar2(10));
--插入记录
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (1, to_date('01-01-2009', 'dd-mm-yyyy'), 'N');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (1, to_date('01-02-2009', 'dd-mm-yyyy'), 'N');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (1, to_date('01-03-2009', 'dd-mm-yyyy'), 'N');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (2, to_date('01-01-2009', 'dd-mm-yyyy'), 'N');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (2, to_date('01-02-2009', 'dd-mm-yyyy'), 'Y');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (2, to_date('01-03-2009', 'dd-mm-yyyy'), 'N');
insert into gl_wsbxx (ID, SBRQ, SBBZ)
values (2, to_date('01-04-2009', 'dd-mm-yyyy'), 'N');
--取得连续三个月单位id
SELECT A.ID
from (SELECT * from GL_WSBXX) a,
(SELECT id, SBRQ, SBBZ, last_day(trunc(add_months(SBRQ, 2))) SBRQ1 from GL_WSBXX) b
WHERE a.id = b.id AND
a.SBRQ >= b.SBRQ AND
a.SBRQ <= b.SBRQ1
