viewvipintegral 是视图

查看表的定义
SELECT DBMS_METADATA.GET_DDL(‘TABLE’,‘TABLE_NAME’) FROM DUAL;

SELECT DBMS_METADATA.GET_DDL(‘VIEW’,‘VIEW_NAME’) FROM DUAL;

Oracle的NVL函数用法
从两个表达式返回一个非 null 值。

语法

NVL(eExpression1, eExpression2)

参数
eExpression1, eExpression2

如果 eExpression1 的计算结果为 null 值，则 NVL( ) 返回 eExpression2。如果 eExpression1 的计算结果不是 null 值，则返回 eExpression1。eExpression1 和 eExpression2 可以是任意一种数据类型。如果 eExpression1 与 eExpression2 的结果皆为 null 值，则 NVL( ) 返回 .NULL.。

返回值类型

字符型、日期型、日期时间型、数值型、货币型、逻辑型或 null 值

说明

在不支持 null 值或 null 值无关紧要的情况下，可以使用 NVL( ) 来移去计算或操作中的 null 值。

select nvl(a.name,‘空得’) as name from student a join school b on a.ID=b.ID

注意：两个参数得类型要匹配

 1 SELECT           T.D_FDATE,2                        T.VC_ZHCODE,3                        NVL(SUM(T.F_FZQSZ), 0) f_price_b,4                        NVL(SUM(T.F_FZQCB), 0) f_cost_b,5                        NVL(SUM(T.F_FGZ_ZZ), 0) f_gz_b,6                        NVL(SUM(T.F_FYZQSZ), 0) f_price_Y,7                        NVL(SUM(T.F_FYZQCB), 0) f_cost_Y,8                        NVL(SUM(T.F_FYGZ_ZZ), 0) f_gz_Y,9                        T.VC_SOURCE,
10                        SYSDATE d_updatetime
11                   FROM GZ_FUND_GZB T

比如这样的判断就很重要啦，因为你不知道哪一行是 is not null 的，也不知道接下来是否要对这个单元格进行运算操作，因此，不能给列填 null，就给它一个 0 ，便于查看，也便于运算。

查询导购业绩报表

 select a.*FROM salesheet b INNER JOIN SalesManApportion a on a.saleGuid = b.guidINNER JOIN Businessperson  bp on bp.guid = a.businessIdwhere b.manualid='330311922203050003e'--- salesheet  销售表--- SalesManApportion  导购业绩分摊表--- Businessperson 导购信息表

alter system kill session ‘245,43584’;

select object_name,machine,s.program,s.sid,

and object_name=upper(‘&tablename’) and o.owner=upper(‘&owner’) order by 1;

这个语句可以查看那个表锁了，需要输入表名和用户名

select decode(request,0,‘Holder:’,‘Waiter:’)||s.inst_id||‘:’||s.sid||‘,’||s.serial# sess, s.BLOCKING_SESSION,s.status,

where (id1,id2,l.type) in
(select id1,id2,type from gv$lock where request>0)
and l.sid=s.sid
and l.inst_id=s.inst_id
order by id1,ctime desc,request;
/

这个SQL看数据库存在的锁信息，持锁会话
