oracle中行列转换，max,listagg使用

需求：求门诊开甲功三项的病人的基本信息与化验结果的数据，

自己的写法是：

select a.sampleno,a.patientname,a.patientid ,listagg(testresult,',')
within GROUP (order by testresult desc) abc
from bslis.l_patientinfo a,bslis.l_testresult b where a.sampleno =b.sampleno and a.examinaim='甲功三项'
group by a.sampleno ,a.patientname,a.patientid

这上面是lis的检验结果

lis中同一个样本号码对应三个testid然后是结果是分三条显示的，所以用了listagg然后就被动用了group by,所以打算lis与his信息union的话就比较难了

=======================================

select a.brid,mzhm,a.brxm,a.sfzh, xzz_qtdz, b.yz_z,b.yz_t, age,patientid from ms_brda a, ys_mz_jzls b ,l_lis_sqd c,ms_yj01 d
where a.brid=b.brbh and a.mzhm=c.patientid and c.doctrequestno=d.sqdh and d.jzxh=b.jzxh
and (b.yz_z is not null or b.yz_t is not null) and c.examinaim like '甲功三项' and c.bed_no is null

 这是his的病人基本信息，lis与his都有patientid，打算Union ,上面提到union很难实现

 =============================================================================

select brid,mzhm,brxm,sfzh,csny, xzz_qtdz,yz_z,yz_t,age,patientid,
max(FT3) FT3,max(FT4) FT4,max(TSH) TSH from (

select a.brid,mzhm,a.brxm,a.sfzh,csny, xzz_qtdz, b.yz_z,b.yz_t, c.age,c.patientid,
f.testresult,f.testid,
case when f.testid = 1111 then f.testresult else '' end FT3,
case when f.testid = 1112 then f.testresult else '' end FT4,
case when f.testid = 1113 then f.testresult else '' end TSH
