② 不是Group by 的表達式
這個XN 或者要在GROUP BY 後面的分組列表中,
或者在要加上聚合函數,如MAX(XN),MIN(SN)等
即,
這樣:
insert into bzrpcxt_pm select bzrxm as xingming ,count(bzrxm) as xiangshu,sum(fs) as zongfen,sum(fs)/count(bzrxm),xn=MAX(XN) from bzrpcxt_cc group by bzrxm order by 1,2
或者:
insert into bzrpcxt_pm select bzrxm as xingming ,count(bzrxm) as xiangshu,sum(fs) as zongfen,sum(fs)/count(bzrxm),xn=MAX(XN) from bzrpcxt_cc group by bzrxm,XN order by 1,2
③ 關於Criteria查詢
a.add(Example.create(user));
List result=criteria.list();
System.out.println("result.size()="+result.size());
return criteria.list();
}
④ 訪問ORCLE資料庫的時候出現ORA-00923未找到要求的 FROM 關鍵字
select BZRXM avg(PF) from BZRPCXT_CC group by BZRXM
就算是ORCLE
也應該是
select BZRXM ,avg(PF) from BZRPCXT_CC group by BZRXM
這樣寫法吧.你少了個,號
