本文讲述Oracle分析函数用法，首先建库：
Sql代码
- create table earnings -- 打工赚钱表
- (
- earnmonth varchar2(6), -- 打工月份
- area varchar2(20), -- 打工地区
- sno varchar2(10), -- 打工者编号
- sname varchar2(20), -- 打工者姓名
- times int, -- 本月打工次数
- singleincome number(10,2), -- 每次赚多少钱
- personincome number(10,2) -- 当月总收入
- )
然后插入实验数据：
Sql代码
- insert into earnings values('200912','北平','511601','大魁',11,30,11*30);
- insert into earnings values('200912','北平','511602','大凯',8,25,8*25);
- insert into earnings values('200912','北平','511603','小东',30,6.25,30*6.25);
- insert into earnings values('200912','北平','511604','大亮',16,8.25,16*8.25);
- insert into earnings values('200912','北平','511605','贱敬',30,11,30*11);
- insert into earnings values('200912','金陵','511301','小玉',15,12.25,15*12.25);
- insert into earnings values('200912','金陵','511302','小凡',27,16.67,27*16.67);
- insert into earnings values('200912','金陵','511303','小妮',7,33.33,7*33.33);
- insert into earnings values('200912','金陵','511304','小俐',0,18,0);
- insert into earnings values('200912','金陵','511305','雪儿',11,9.88,11*9.88);
- insert into earnings values('201001','北平','511601','大魁',0,30,0);
- insert into earnings values('201001','北平','511602','大凯',14,25,14*25);
- insert into earnings values('201001','北平','511603','小东',19,6.25,19*6.25);
- insert into earnings values('201001','北平','511604','大亮',7,8.25,7*8.25);
- insert into earnings values('201001','北平','511605','贱敬',21,11,21*11);
- insert into earnings values('201001','金陵','511301','小玉',6,12.25,6*12.25);
- insert into earnings values('201001','金陵','511302','小凡',17,16.67,17*16.67);
- insert into earnings values('201001','金陵','511303','小妮',27,33.33,27*33.33);
- insert into earnings values('201001','金陵','511304','小俐',16,18,16*18);
- insert into earnings values('201001','金陵','511305','雪儿',11,9.88,11*9.88);
