uploadedexceldata Table having  column

 

Id,Name,Mobile,Email,City,State,DataId,Amount,Date, UploadedDate, Source

 

another Tble Leadtable Having column Mobile,DataId,Source 

 

whenever I upload excelsheet the data of Excelsheet inserted into uploadedexceldata

and the Leadtable  is updated on the matched column mobile of uploadedexceldata

 

the field which are going to update is DataId,Source .

 

all is running on iis6.0.
