从EXCEL中导入表格数据到SQL SERVER里面!不用SQL SERVER的数据库导入器!(70分)

网上有许多从EXCEL中导入表格数据到SQL SERVER里面的程序!可好象都不太理想!我需要一个利用ADO对EXCEL进行操作,并把EXCEL里面指定格式的数据导入到SQL SERVER里面.导入时可以对EXCEL里面的某些表格数据进行合并,只把合并后的数据导入SQL数据库里面.急切需要源代码!谢谢

我也想把excel数据导入到sql server中，多谢大家帮助！！！

--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'
,'Excel 5.0;HDR=YES;DATABASE=c:/test.xls',sheet1$)

--如果导入数据并生成表
select * into 表 from
OPENROWSET('MICROSOFT.JET.OLEDB.4.0'
,'Excel 5.0;HDR=YES;DATABASE=c:/test.xls',sheet1$)
他们说这些可以,但我总是出问题,郁闷啊,有人帮帮我吗?

procedure TForm1.btn_EXCEL2MSSQLClick(Sender: TObject);
begin
ADOConnection1.ConnectionString:='Provider=SQLOLEDB.1;Password=KCSOFT58;Persist Security Info=True;User ID=SA;Initial Catalog=KCSOFT_HIS;Data Source=CHEN';
ADOConnection1.Execute('SELECT * into [abc] FROM OpenDataSource( '
+QuotedStr('Microsoft.Jet.OLEDB.4.0')+','
+QuotedStr('Data Source="G:/mysmallexe/excel2sql/yp.xls";Extended Properties=excel 8.0')+')...[Abc]');
end;

异构数据库之间的导入导出示例，abc为表,包含以下导入与导出
MSSQL2EXCEL EXCEL2MSSQL MSSQL2VFP VFP2MSSQL
MSSQL2access access2MSSQL excel2access access2excel
，txt2MSSQL，MSSQL2txt

ADOConnection1.Execute('insert into [abc] select * from drug_yk in [ODBC] [ODBC;Driver=SQL Server;UID=sa;PWD=kcsoft58;Server=127.0.0.1;DataBase=kcsoft_his]');
