建立SQL视图
create OR REPLACE VIEW c4 as ---建立试图C4 select custcode, CONCAT(substr(0000000000,-(length(custcode)-length(custcode+1))),custcode+1) custcode2, id, CAST(id as int) ID2, ---把编码右三位的列转换成数字 custname, areaclcode, pk_areacl from ( select custcode, replace (substr(custcode,-4),'*','0' ) id, ---把编码右三位取出来 custname, areaclcode, pk_areacl from ( select custcode , custname , areaclcode, bd_cubasdoc.pk_areacl from bd_cubasdoc,bd_areacl where bd_cubasdoc.pk_areacl=bd_areacl.pk_areacl )aa where areaclcode like '07%' ---取地区分类07开头的行 )a ; create OR REPLACE VIEW c5 as ---建立试图C5 select t1.maxid,t1.areaclcode,t2.custcode,t2.custcode2,t2.id,t2.custname,pk_areacl --取C4表的值和分组统计的值 from ( select MAX(id2) maxid,areaclcode from c4 group by areaclcode ---根据地区分类分组,取ID2列(把编码右三位的列转换成数字)最大值 )t1 left join c4 t2 on t1.maxid=t2.id2 and t1.areaclcode=t2.areaclcode ---表和视力的ID和地区分类名称都要相等
查询 C5
select * from C5
客商申请单 地区分类 增加编辑公式
custcode->getColValue(C5,custcode2,pk_areacl,pk_areacl)
