Unidac连接Excel文件

终于找到一个连接字符串，记录一下

UniConnection1.ConnectString := Format('Provider Name=ODBC;Server="DRIVER=Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb); DBQ=%s"', FileName);

UniConnection1.connected:=true;

UniConnection1.gettablenames(memo1.lines,false,false);

'select * from '+memo1.lines.strings\[i+']'
