2008-05-30 我在网上找到一个网址, 俄国人的,里面关于 SQLDMO的说明有很大的帮助。 地址如下:http://www.delphiturkiye.com/forum/viewtopic.php?f=19&t=20072 希望得空的时候,再来好好研究。 首先, 需要把 SQLDMO.DLL 文件导入到DELPHI 中。sqldmo.dll 是一个com, 安装SQLServer 后位于 Program Files\Microsoft SQL Server\80\Tools\Binn 打开Delphi,Project菜单->Import Type Library...,在列表框中找到"Microsoft SQLDMO ObjectLibrary(Version 8.0)" 导入完后,当我们Compile的时候却发现这个单元无法编译, 提示大意为ID重复定义, 这个简单, 找到不能编辑的地方,把ID 改成 xID就行了,这样就可以编译通过。 在使用过程中,我发现在很多情况下,SQLDMO_TLB.pas中的类是不能用的, 出现av错误。比如Restore,必须这样使用: CreateOleObject('SQLDMO.Restore'); 定义相同的类,如TTABLE等,这个需要处理一下,在TTABLE前加单元名,如DBE.TTABLE 或 SQLDMO_TLB.TTABLE 就OK啦。 下需介绍几个常用的功能。 取SQLSERVER的版本
