1、取下列语句中的EYPGG0值

select a.YPNM00,a.YPBM00,a.YPMC00,a.YPGG00,a.KCDW00,a.PYSM00,a.WBSM00,
a.YPTYM0,a.ZFZGDJ,a.SCCJBH,a.SFYBML,a.EYPTYM,a.EYPMC0,a.EKCDW0,a.BZ0000,
a.EYPGG0,a.CPID00,a.GHSID0,b.*,a.GHDWNM,c.GHDWMC,a.ZBXH00,a.PZWH00,a.ZBQMC0,a.TJLXBH,a.PYSMTY,
(SELECT B.LBMC00 FROM BM_YPLB00 B WHERE a.LBBH00=B.LBBH00) LBMC00,
(SELECT B.YLMC00 FROM BM_YPYL00 B WHERE a.LBBH00=B.LBBH00 AND a.YLBH00=B.YLBH00) YLMC00,
(SELECT B.JXMC00 FROM BM_YPJX00 B WHERE a.LBBH00=B.LBBH00 AND a.JXBH00=B.JXBH00) JXMC00 
  from bm_yd0000 a,BM_YPSCCJ b,BM_YPGHDW c
 where a.LBBH00 like '0%'
 and a.YLBH00 like '01%'
 and a.JXBH00 like '%'
 and a.YKBMBH=301
 and a.TZRQ00 IS NULL and a.SCCJBH=b.SCCJBH(+) and a.GHDWNM=c.GHDWNM(+)
 order by a.YPBM00 

2、DDD值=EYPGG0值*用药总量

3、如果病人有用多个抗生素，则总DDD值为多个抗生素药品DDD值总和
