ruby on rails - How get the error of ActiveRecord::Base.connection.execute? -

  begin      activerecord::base.transaction        // ...       sanitized_sql = "insert pinfo ..."       activerecord::base.connection.execute(sanitized_sql)      end    rescue      // how can error?           end 

in webrick console, error (1967-07-16?00:00:00) shown as:

execute (0.0ms) odbc::error: 22008 (241) [unixodbc][freetds][sql server]syntax error converting datetime character string.: insert pinfo (birthdate) values ('1967-07-16?00:00:00') execute (0.8ms) if @@trancount > 0 rollback transaction

how can above error message (odbc::error: 22008 (241) ...) raised activerecord::base.connection.execute in rescue?

 begin     activerecord::base.transaction      // ...   sanitized_sql = "insert pinfo ..."   activerecord::base.connection.execute(sanitized_sql)    end  rescue exception => exc     logger.error("message log file #{exc.message}")     flash[:notice] = "store error message #{exec.message}"   end 

thanks
