/**********************Excel导到Txt****************************************/
想用
select * into opendatasource(...) from opendatasource(...)
实现将一个Excel文件内容导入到一个文本文件

假设Excel中有两列，第一列为姓名，第二列为很行帐号(16位)
且银行帐号导出到文本文件后分两部分，前8位和后8位分开。

邹健：
如果要用你上面的语句插入的话,文本文件必须存在,而且有一行:姓名,银行账号1,银行账号2
然后就可以用下面的语句进行插入
注意文件名和目录根据你的实际情况进行修改.

insert into
opendatasource('MICROSOFT.JET.OLEDB.4.0'
,'Text;HDR=Yes;DATABASE=C:\'
)...[aa#txt]
--,aa#txt)
--*/
select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8)
from
opendatasource('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:\a.xls'
--,Sheet1$)
)...[Sheet1$]

如果你想直接插入并生成文本文件,就要用bcp

declare @sql varchar(8000),@tbname varchar(50)

--首先将excel表内容导入到一个全局临时表
select @tbname='[##temp'+cast(newid() as varchar(40))+']'
,@sql='select 姓名,银行账号1=left(银行账号,8),银行账号2=right(银行账号,8)
into '+@tbname+' from
opendatasource(''MICROSOFT.JET.OLEDB.4.0''
,''Excel 5.0;HDR=YES;IMEX=2;DATABASE=c:\a.xls''
)...[Sheet1$]'
exec(@sql)

--然后用bcp从全局临时表导出到文本文件
set @sql='bcp "'+@tbname+'" out "c:\aa.txt" /S"(local)" /P"" /c'
exec master..xp_cmdshell @sql

--删除临时表
exec('drop table '+@tbname)

ADOConnection2 =&gt; Access
*/
sql = "SELECT * INTO jyjh in \"c:\\temp\"[dbase 5.0;] FROM jyjh";
ADOConnection2-&gt;Execute(sql);

c:\temp\aaa.dbf to Access,
ADOConnection 指向Access
语句是  select * into bbb from aaa in 'c:\temp' 'dbase 5.0;'

在Form上放一个ADOConnection,连结指向目标Access库
比如txt文件在c:\temp\aaaa.txt
就执行
ADOConnection.Connected := True;
ADOConnection.Execute('Select * Into abcd From [Text;Database=c:\temp].aaaa.txt');

将Oracle导入到文本文件
连接串
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\temp;Extended Properties="text;HDR=YES;";Persist Security Info=False
SQL语句
SELECT * into aaa.txt  FROM Tab1 IN [ODBC]
[ODBC;Driver={Microsoft ODBC for Oracle};UID=oracle;PWD=oracle;SERVER=yourdata;]

将Oracle导入到Access
连接串
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\temp\db1.mdb;Persist Security Info=False
SQL语句
SELECT * into tablename  FROM Tab1 IN [ODBC]
[ODBC;Driver={Microsoft ODBC for Oracle};UID=oracle;PWD=oracle;SERVER=yourdata;]

DBase 5.0
DBASE IV
FoxPro 3.0

text;HDR=YES;FMT=Delimited

SELECT * into aaa

Excel联接ADO串
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\temp\a.xls;Extended
Properties="Excel 8.0;HDR=Yes;";Persist Security Info=False
Extended Properties参数属性这样写 Excel 5.0;HDR=YES;IMEX=1
IMEX=1就是指混合型转换为文本
SQLServer从Excel取数
SELECT *
FROM OpenDataSource('Microsoft.Jet.OLEDB.4.0','Data Source="C:\temp\b.xls";Extended Properties="Excel 5.0;HDR=Yes;";Persist Security Info=False')...sheet1$

将SQLServer导入到文本文件
连接串
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\temp;Extended Properties="text;HDR=YES;";Persist Security Info=False
SQL语句
SELECT * into aaa.txt  FROM Tab1 IN [ODBC]
[ODBC;Driver=SQL Server;UID=sa;PWD=;Server=127.0.0.1;DataBase=Demo;]
要改变分隔符，可以修改
Schema.ini文件。该文件中指明分割符，如：
    [yourfile.txt]
    ...
    Format=Delimited(|)
更详细的例子可以参考：微软的Knowledge Base的文章："Q149090 CC: How to Use Schema.ini for Accessing Text Data"和微软的Knowledge Base的文章："Q187670 OWT Use RDO and ODBC Text Driver to Open a Delimited Text"。

ADOConnection 指向excel, 用Jet4.0 ,Extended properties设为Excel 8.0
SELECT * into table  FROM Tab1 IN [ODBC]
[ODBC;Driver=SQL Server;UID=sa;PWD=;Server=127.0.0.1;DataBase=Demo;]

insert into gds_order select * from gds_order

在SQLServer中执行
SELECT * into bmk
FROM OpenDataSource( 'Microsoft.Jet.OLEDB.4.0',
  'Data Source="e:\share";User ID=Admin;Password=;Extended properties=dBase 5.0')...bmk
这样就可以把e:\share中的bmk.dbf表导入到Sqlserver中，
