从dbase文件中,导入数据到sql数据库中,很简单,直接用下面的语句:
/*===================================================================*/
--如果接受数据导入的表已经存在
insert into 表 select * from
openrowset('microsoft.jet.oledb.4.0'
,'dbase 5.0;database=c:/','select * from [test.dbf]')
--如果导入数据并生成表
select * into 表 from
openrowset('microsoft.jet.oledb.4.0'
,'dbase 5.0;database=c:/','select * from [test.dbf]')
/*===================================================================*/
--如果从sql数据库中,导出数据到dbase,如果dbase文件已经存在,就可以简单的用:
insert into
openrowset('microsoft.jet.oledb.4.0'
,'dbase 5.0;database=c:/','select * from [test.dbf]')
select * from 表
/*--说明:
database=c:/ c:/是dbf文件的存放目录
'select * from [test.dbf] test.dbf是指dbf文件名
--*/
--如果dbase文件不存在,就需要用到下面的存储过程了.
/*--数据导出dbase
导出表中的数据到dbase,如果文件不存在,将自动创建文件
基于通用性考虑,仅支持导出标准数据类型
