编程实现SQL Server数据库导入导出操作

******* 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
SELECT * FROM openrowset('MicroSoft.Jet.OleDB.4.0',
'Excel 5.0;HDR=yes;Database=c:/test.xls',sheet1$)
--------------------------------------------------------
SELECT *
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:/test.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions

SELECT cast(cast(科目编号 as numeric(10,2)) as nvarchar(255))+'　' 转换后的别名
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
'Data Source="c:/test.xls";User ID=Admin;Password=;Extended properties=Excel 5.0')...xactions

/** 导入文本文件
EXEC master..xp_cmdshell 'bcp "dbname..tablename" in c:/DT.txt -c -Sservername -Usa -Ppassword'

/** 导出文本文件
EXEC master..xp_cmdshell 'bcp "dbname..tablename" out c:/DT.txt -c -Sservername -Usa -Ppassword'
或
EXEC master..xp_cmdshell 'bcp "SELECT * FROM dbname..tablename" queryout c:/DT.txt -c -Sservername -Usa -Ppassword'

导出到TXT文本，用逗号分开
exec master..xp_cmdshell 'bcp "库名..表名" out "d:/tt.txt" -c -t ,-U sa -P password'

BULK INSERT 库名..表名
FROM 'c:/test.txt'
WITH (
FIELDTERMINATOR = ';',
ROWTERMINATOR = '/n'
)

--/* dBase IV文件
SELECT * FROM
OPENROWSET('MICROSOFT.JET.OLEDB.4.0'

--/* dBase III文件
SELECT * FROM

--/* FoxPro 数据库
SELECT * FROM openrowset('MSDASQL',

/**************导入DBF文件****************/
SELECT * FROM openrowset('MSDASQL',

/***************** 导出到DBF ***************/
如果要导出数据到已经生成结构(即现存的)FOXPRO表中,可以直接用下面的SQL语句

INSERT INTO openrowset('MSDASQL',
'Driver=Microsoft Visual FoxPro Driver;SourceType=DBF;SourceDB=c:/',
'SELECT * FROM [aa.DBF]')
SELECT * FROM 表

说明:
SourceDB=c:/ 指定foxpro表所在的文件夹
aa.DBF 指定foxpro表的文件名.

/*************导出到Access********************/
INSERT INTO openrowset('Microsoft.Jet.OLEDB.4.0',
'x:/A.mdb';'admin';'',A表) SELECT * FROM 数据库名..B表

/*************导入Access********************/
INSERT INTO B表 selet * FROM openrowset('Microsoft.Jet.OLEDB.4.0',
'x:/A.mdb';'admin';'',A表)
