newb: Creating Exception

[johnny]

I want to print individual exception for database connection, sql
execution, database closing, closing the cursor.  Can I do it with one
try..catch or I need a nested try...catch?

        conn = adodb.NewADOConnection('mysql')
        conn.Connect('localhost', 'temp', 'temp', 'temp')

        sql = r"update file set pdf_file_path='" +finalFile+r"' where
file_path='"+p+r"'"


        cursor = conn.Execute(sql)
        rows = cursor.Affected_Rows()

        cursor.close()
        conn.close()

Thank you for your FOUNTAIN OF WISDOM...
