[ABI 5.2] 过滤条件怎样加if判断

sql如下，用户123456还是只查询到了 用户是123456 的数据

SELECT LIMIT 1000 * FROM (select MAX(a.bankname) as B2,MAX(a.startdate) as C2,sum(a.dkamount) as D2,MAX(a.tbrname) as E2,MAX(a.tbrphone) as F2,MAX(a.lpdate) as G2,sum(a.lpamount) as H2,sum(a.yhamount) as I2,MAX(a.identifynumber) as J2,MAX(a.czadress) as K2,MAX(a.gsxy) as L2,MAX(a.administrator) as M2,MAX(a.issw) as N2,MAX(a.issl) as O2,MAX(a.tqphone) as P2,MAX(a.isjq) as Q2,a.policyno as A2
from (select a.id,a.policyno,a.bankname,a.startdate,a.dkamount,a.tbrname,a.tbrphone,a.lpdate,a.lpamount,a.yhamount,a.identifynumber,a.czadress,a.gsxy,case when c.username is not null then c.username else a.administrator end administrator ,
case when a.issw='1' then '是' when a.issw='0' then '否' else a.issw end issw,case when a.issl='1' then '是' when a.issl='0' then '否' else a.issl end issl,a.tqphone,case when a.isjq='1' then '是' when a.isjq='0' then '否' else a.isjq end isjq
from xd_lpkh a ,outer xd_ryxx c
where a.administrator=c.usercode
) a
where (((a.administrator = '123456') and (2>1) or not (a.administrator = '123456') and (a.administrator = '123456')))
group by a.policyno)

修改了下if判断，可以实现效果了，感谢老师
