Re: Re: Totaling Time

In the TIME TOTAL CALCULATION SUBROUTINE i need to take the SQL fields (start_hour, start_minute, end_hour, end_minute) from a row consistion of (oid,emp_id,date,f_name,l_name,start_hour, start_minute,start_stamp, end_hour, end_minute, end_stamp, comment). Then update the 'total_time' field WHERE oid = $sav_oid Field with that total. Oh yes. 24 hour format would be good.


#!/usr/bin/perl
### clock_out.cgi

use CGI qw/:standard/;
require "common.sub";


$oid = $ENV{QUERY_STRING};
$sav_oid = $oid;

$end_hour = &filter(param(hour));
$end_minute = &filter(param(minute));
$comment = &filter(param(comment));

print header;

&Create_DB_Connection;
&clock_out;
&print_output;

# Disconnect from the database
$sth->finish;
$dbh->disconnect;

################  BEGIN CLOCKOUT SUBROUTINE

sub clock_out{

  $SQL = "UPDATE timeclock SET 
         end_hour = '$hour', 
         end_minute   = '$minute',  
         end_stamp    = CURRENT_TIMESTAMP, 
                  
        WHERE
         oid      = '$sav_oid'
       ";  
  &Do_SQL;
} # End of clock_out

################  END CLOCKOUT SUBROUTINE

################  BEGIN TIME TOTAL CALCULATION SUBROUTINE

sub calc_total{

  $SQL = "select oid,* FROM timeclock WHERE oid = $sav_oid";
           
  &Do_SQL;

So if I read this correctly, you want to figure out the time that elapsed between start_hour, start_min, end_hour, and end_min, and then store it back in your db I think I can safely say that it's impossible to detemine ( correctly ) the amount of time that has elapsed by just knowing the hour and minutes, as RheTbull says. You would need to have some sort of date/time entries for start time and end time, then I think Postgres provides you with ways to calculate an interval type.	[reply]
