一个Excel导入SQL Server的例子
这个是Excel的,比如是test.xls欠费年份 欠费开始月份 欠费结束月份 应缴金额(月租)
2001 9 12 94.4
2008 5 12 88.8
2010 8 12 90.4
___________________________________________
这个是表:比如是a表
a(pk,int,not null) //主键,自动增长
b(varchar(19),null) //费款所属期
c(decimal(10,2),null) //应缴金额
___________________________________________
现在我要将test.xls中的数据导入到a表,从开始月份到结束月份要做循环导入,比如第一条2001年的从9月到12月要录入4条数据到a表,导入后的格式如:
select * from a
a b c
1 2001-09 94.4
2 2001-10 94.4
3 2001-11 94.4
4 2001-12 94.4
数据库是:MS Sql server 2008

思路一:可以使用OpenRowset查询导入到表变量中,再用游标循环赋值。方法如下:
use testdb2go/*******************建立测试数据***3w@live.cn***********************/IF NOT OBJECT_ID('') IS NULLDROP TABLE GOCREATE TABLE ( int> NVARCHAR(20) null, decimal(10,2) null)go/*******************启用Ad Hoc Distributed Queries***3w@live.cn***********************/--------USE master --
