上载CSV文件，PHP / MySQL查询

Question

i have a .csv file that looks like this...

     Name            AC-No.      Time                State        Exception   Operation

Johnny Starks Depp   1220    4/12/2013 12:45:18 AM  Check In        OK   
Johnny Starks Depp   1220    4/12/2013 5:46:58 AM   Out             Out 
Johnny Starks Depp   1220    4/12/2013 6:22:41 AM   Out Back        Out  
Johnny Starks Depp   1220    4/12/2013 10:42:17 AM  Check Out       Repeat   
Johnny Starks Depp   1220    4/12/2013 10:42:19 AM  Check Out       OK

i can already upload this to my database. my problem is that, the result it shows in the table. In mysql database I have a TABLE with columns ( Name, ACNo. , Date, CheckIn, Breakout, Breakin, CheckOut ). What I want to happen that i cannot do right is.. the record/s in the .csv file with the same DATE ( which is shown in the TIME Column ) will be in just one same row along with the Check In, BreakOut, BreakIn, and CheckOut in the TABLE and wont result a multiple record. like this..

     Name         |ACNo |     Date  | CheckIn     |  Breakout  |   Breakin  | Checkout
                  |     |           |             |            |            |
Johnny Starks Depp|1220 | 4/12/2013 | 12:45:18 AM | 5:46:58 AM | 6:22:41 AM | 10:42:19 AM

Now.. i already did the above example of what i want to happen in the table but... when i check the table, yes it has different dates per row but the time in (CheckIn, Breakout, Breakin, Checkout) are wrong. Wrong, because the time for example in the DATE 4/12/2013 is recorded in the DATE 4/13/2013. What is wrong with the codes i used? Or is there any way else i can do this? these are my codes:

<?php

$conn = mysql_connect("localhost","root","") or die(mysql_error());
mysql_select_db("dtrlogs",$conn);

$datehere ="";

if(isset($_POST['Submit']))
{

$file = $_FILES['file']['tmp_name'];

if($file == "")
{
    ?>
    <script type="text/javascript">
    alert('No File Selected!');
    </script>
    <?php
}

else
{
$handle = fopen($file,"r");
while(($fileop = fgetcsv($handle,1000,";")) !==false)
{
    $Name = $fileop[0];
    $ACNo = $fileop[1];
    $Time = $fileop[2];
    $State = $fileop[3];
    $NewState = $fileop[4];
    $Exception = $fileop[5];
    $Operation = $fileop[6];

    //i separated time/date in the Column TIME in the .csv file
    $date = date('m/d/Y', strtotime($Time));
    $hours = date('H:i:s A', strtotime($Time));


    //this is what i used to prevent multiple dates
    if($datehere != $date) {

        $datehere = $date;
    }
    else{

        $date = "";
    }







    //this is to insert the name and acno to the other table. 
    //(this is for the lists of employee)

    $sql=mysql_query("SELECT * FROM employee Where ACNo = '$ACNo'");
    $row=mysql_fetch_array($sql);
    if($row == 0) {

       $sql1 = mysql_query("INSERT INTO employee(ACNo, Name) VALUES('$ACNo','$Name')");
    }



    //Inserts record if Date is not yet recorded and if already has just updates 
    //the row's column (Checkin, breakout, breakin and Checkout) 
    //with its correct time according to the date

    $query = mysql_query("SELECT * FROM dtrs Where ACNo = '$ACNo' AND Date = '$date'");
    $rows = mysql_fetch_array($query);
    if($rows == 0) {

    $sql2 = mysql_query("INSERT INTO dtrs(Name, ACNo, Date, CheckIn, BreakOut, 
    BreakIn,CheckOut) 
    VALUES('$Name','$ACNo','$date','$CheckIn','$Breakout','$Breakin','$Checkout')");

    }
    else{

    $sql2 = mysql_query("Update dtrs Set CheckIn = '$CheckIn', BreakOut = 
    '$Breakout', BreakIn = '$Breakin', CheckOut = '$Checkout'");
    }







    //this is my conditions to identify whether the TIME/HOUR is 
    //Stated as CheckIn, Breakout, Breakin, or Checkout

    if($NewState == "Check In" || $State == 'Check In' && $Exception == "OK") {

        if($Exception == "Invalid" || $Exception == "Repeat")
        {}
        else {
            $CheckIn = $hours;
        }
    }
    if($State == 'Out' && $Exception == "Out") {

        if($Exception == "Invalid" || $Exception == "Repeat")
        {}
        else {
            $Breakout = $hours;
        }
    }
    if($State == 'Out Back' && $Exception == "Out") {

        if($Exception == "Invalid" || $Exception == "Repeat")
        {}
        else {
            $Breakin = $hours;
        }
    }
    if($NewState == "Check Out" || $State == "Check Out" && $Exception == "OK") {

        if($NewState == "Check In")
        {}
        else {
            $Checkout = $hours;
        }
     }


}

Answer 1

I would suggest possibly loading to a transient table, and from that extracting the details to use to populate your real table.

For example, if you loaded you CSV file to a table called LoadTable (not a temp table, as you can only use a temp table once in a piece of SQL), you could extract the distinct name and account number, then join that against subselects to get the max event times for each of the relevant events.

Something like this:-

SELECT DerivMain.Name, 
    DerivMain.ACNo, 
    DerivMain.EventDate, 
    DATE_FORMAT(DerivCheckIn.EventDateTime, '%l:%i:%s %p'), 
    DATE_FORMAT(DerivBreakout.EventDateTime, '%l:%i:%s %p'),  
    DATE_FORMAT(DerivBreakin.EventDateTime, '%l:%i:%s %p'), 
    DATE_FORMAT(DerivCheckout.EventDateTime, '%l:%i:%s %p')
FROM (SELECT DISTINCT Name, ACNo, DATE(STR_TO_DATE(Date,'%c/%e/%Y %l:%i:%s %p')) As EventDate FROM LoadTable) DerivMain
LEFT OUTER JOIN (SELECT Name, ACNo, MAX(STR_TO_DATE(Date,'%c/%e/%Y %l:%i:%s %p') AS EventDateTime) FROM LoadTable WHERE State = 'Check In' GROUP BY Name, ACNo) DerivCheckIn
ON DerivMain.Name = DerivCheckIn Name AND DerivMain.ACNo = DerivCheckIn.ACNo 
LEFT OUTER JOIN (SELECT Name, ACNo, MAX(STR_TO_DATE(Date,'%c/%e/%Y %l:%i:%s %p') AS EventDateTime) FROM LoadTable WHERE State = 'Out' GROUP BY Name, ACNo) DerivBreakout
ON DerivMain.Name = DerivBreakout Name AND DerivMain.ACNo = DerivBreakout.ACNo 
LEFT OUTER JOIN (SELECT Name, ACNo, MAX(STR_TO_DATE(Date,'%c/%e/%Y %l:%i:%s %p') AS EventDateTime) FROM LoadTable WHERE State = 'Out Back' GROUP BY Name, ACNo) DerivBreakin
ON DerivMain.Name = DerivBreakin Name AND DerivMain.ACNo = DerivBreakin.ACNo 
LEFT OUTER JOIN (SELECT Name, ACNo, MAX(STR_TO_DATE(Date,'%c/%e/%Y %l:%i:%s %p') AS EventDateTime) FROM LoadTable WHERE State = 'Check Out' GROUP BY Name, ACNo) DerivCheckout
ON DerivMain.Name = DerivCheckout Name AND DerivMain.ACNo = DerivCheckout.ACNo
