sql server导入 导出数据
sql 表和表之间到导入
表A导入到表B
insert into B Select * from A
表A 的框架结构导入到表B不导入数据
select * into B from A
以下都是参考网上归纳总结的：
select * from OPENROWSET(''MICROSOFT.JET.OLEDB.4.0''
,''Excel 5.0;HDR=YES;DATABASE=c:\1.xls'',sheet2$)
导入导出大全
******* 导出到excel
EXEC master..xp_cmdshell ''bcp SettleDB.dbo.shanghu out c:\temp1.xls -c -q -S"GNETDATA/GNETDATA" -U"sa" -P""''
/*********** 导入Excel

set @bcpString='BCP "select * from CACDB_S1000.dbo.tYHJBXX" queryout "d:\aaa.txt" -c -S "localhost" -U "sa" -P "xxxxxx"'
EXEC master..xp_cmdshell @bcpString

实例 2 导出
EXEC master..xp_cmdshell 'bcp "CACDB_S1000.dbo.tYHJBXX111" out "d:\bbb.txt" -c -S "localhost" -Usa -P "xxxxxx"'
实例 3 导入
EXEC master..xp_cmdshell 'bcp "CACDB_S1000.dbo.tYHJBXX111" in "d:\aaa.txt" -c -S "localhost" -Usa -P "xxxxxx"'
实例 4 导入

实例 5 导出到excel
EXEC master..xp_cmdshell 'bcp "CACDB_S1000.dbo.tYHJBXX111" out "d:\temp1.xls" -c -S "localhost" -Usa -P "xxxxxx"'
实例 6 复制表结构 同时也把表中的数据复制到新表中（执行此操作时 新的表名在数据库中不应该存在）
select * into tYHJBXX222 from tYHJBXX

/*
用bcp实现的存储过程
实现数据导入/导出的存储过程
根据不同的参数,可以实现导入/导出整个数据库/单个表
调用示例:
--导出调用示例
----导出单个表
exec file2table 'localhost','sa','xxxxxx','CACDB_S1000.dbo.tYHJBXX','d:\tYHJBXX.txt',1
----导出整个数据库 (执行该操作之前要先在d盘根目录下建d:\CACDB_S1000文件夹)
exec file2table 'localhost','sa','xxxxxx','CACDB_S1000','d:\CACDB_S1000',1
--导入调用示例
----导入单个表 (执行此操作前，表必须在数据库中存在)
exec file2table 'localhost','sa','xxxxxx','CACDB_S1000.dbo.tYHJBXX','d:\tYHJBXX.txt',0
----导入整个数据库
exec file2table 'localhost','sa','xxxxxx','CACDB_S1000','d:\CACDB_S1000',0
