PHP - How To Compare Two Query Results
I am able to run and display two queries I need for my program but having issues comparing the two result sets. If they are identical, means both tables are also identical (the query is for the table's schemas in MS-SQL)
Here's the relevant part ... Code: [Select] //Variables $table_name=$_POST['table_name']; // Connect via Windows authentication $server = 'win1\i01'; //Connection info for PRO $connectionInfoPRO = array( 'Database' => 'adventureworks', 'CharacterSet' => 'UTF-8' ); $dbPRO = sqlsrv_connect($server, $connectionInfoPRO); if ($dbPRO === false) { exitWithSQLError('Database connection to PRO failed'); } //Connection info for ITG $connectionInfoITG = array( 'Database' => 'adventureworksCOPY', 'CharacterSet' => 'UTF-8' ); $dbITG = sqlsrv_connect($server, $connectionInfoITG); if ($dbITG === false) { exitWithSQLError('Database connection to ITG failed'); } /* Set up and execute the query. */ $query1 = "SELECT COLUMN_NAME, DATA_TYPE, ORDINAL_POSITION, COLUMN_DEFAULT, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='$table_name'"; // Run PRO query $qresult1 = sqlsrv_query($dbPRO, $query1); if ($qresult1 === false) { exitWithSQLError('Query of product data failed.'); } echo '<tr><th>NAME</th><th>TYPE</th><th>POSITION</th><th>DEFAULT</th><th>LENGHT</th><th>IS NULLABLE</th></tr>'; // Retrieve individual rows from the result while ($row1 = sqlsrv_fetch_array($qresult1)) { echo '<tr><td>', htmlspecialchars($row1['COLUMN_NAME']), '</td><td>', htmlspecialchars($row1['DATA_TYPE']), '</td><td>', htmlspecialchars($row1['ORDINAL_POSITION']), '</td><td>', htmlspecialchars($row1['COLUMN_DEFAULT']), '</td><td>', htmlspecialchars($row1['CHARACTER_MAXIMUM_LENGTH']), '</td><td>', htmlspecialchars($row1['IS_NULLABLE']), "</td></tr>\n"; } // null == no further rows, false == error if ($row1 === false) { exitWithSQLError('Retrieving schema failed.'); } //Run ITG query $query2 = "SELECT COLUMN_NAME, DATA_TYPE, ORDINAL_POSITION, COLUMN_DEFAULT, CHARACTER_MAXIMUM_LENGTH, IS_NULLABLE FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME='$table_name'"; $qresult2 = sqlsrv_query($dbITG, $query2); if ($qresult2 === false) { exitWithSQLError('Query of product data failed.'); } echo '<tr><th>NAME</th><th>TYPE</th><th>POSITION</th><th>DEFAULT</th><th>LENGHT</th><th>IS NULLABLE</th></tr>'; // Retrieve individual rows from the result while ($row2 = sqlsrv_fetch_array($qresult2)) { echo '<tr><td>', htmlspecialchars($row2['COLUMN_NAME']), '</td><td>', htmlspecialchars($row2['DATA_TYPE']), '</td><td>', htmlspecialchars($row2['ORDINAL_POSITION']), '</td><td>', htmlspecialchars($row2['COLUMN_DEFAULT']), '</td><td>', htmlspecialchars($row2['CHARACTER_MAXIMUM_LENGTH']), '</td><td>', htmlspecialchars($row2['IS_NULLABLE']), "</td></tr>\n"; } // null == no further rows, false == error if ($row2 === false) { exitWithSQLError('Retrieving schema failed.'); } How can I compare $row1 and $row2 here (the query results for each one) and validate if they both have same results, each and all columns.

Query About How To Retrieve A Password From The Database And Compare To The One The User Has Entered
I have two arrays, X and Y, which contain names. The arrays are of the same size. The arrays are related to each other such that for each pair X[n] , Y[n] X is friends with Y. For example: X[0,1,2] = [Link, Cloud, Cloud, Mario, Mario, Luigi] Y[0,1,2] = [Zelda, Barrett, Tifa, Luigi, Bowser, Mario] Link is friends with Zelda Cloud is friends with Barrett and Tifa Mario is friends with Luigi and Bowser Luigi is friends with Mario I want to loop through these arrays and, for each unique name, find all of that person's friends. I then want to print the results to a text file, like so: Link, Zelda Cloud, Barrett, Tifa Mario, Luigi Luigi, Mario I know how to do this theoretically, but I just need help with the PHP syntax. Thanks very much. Hi, I need to compare records in a table based on the 'datetime' field, like if the difference between time is less than 15min. need to combine the records(rows) as a single resultant row until the time difference between them is less than 15min and when a record's time difference is >15min that should return as another row and so on. Please find following sample table and the required output format Sample Table: Code: [Select] ID NAME DATETIME 1 aaa 2011-10-10 06:30:00 2 bbb 2011-10-10 06:33:00 3 ccc 2011-10-10 06:38:00 4 ddd 2011-10-10 06:40:00 5 eee 2011-10-10 07:10:00 6 ffff 2011-10-10 07:14:00 7 sss 2011-10-10 08:16:00 8 jjj 2011-10-10 08:26:00 9 kkk 2011-10-10 08:28:00 10 mm 2011-10-10 09:46:00 11 ppp 2011-10-10 09:49:00 12 qqq 2011-10-10 09:52:00 Output Needed : Code: [Select] IDs START DATETIME END DATETIME 1,2,3,4 2011-10-10 06:30:00 2011-10-10 06:40:00 5,6 2011-10-10 07:10:00 2011-10-10 07:14:00 7,8,9 2011-10-10 08:16:00 2011-10-10 08:28:00 10,11,12 2011-10-10 09:46:00 2011-10-10 09:52:00 You can see 1st row in the output table having IDs 1,2,3,4 coz the time difference between them is less than 15minutes (it doesn't means time difference between start and end; it is actually the time difference between current record and previous one ; ie; ID-1 and ID-2 have difference less than 15min and ID-2 & ID-3 have difference less than 15min and ID-3 & ID-4 have difference less than 15min, so those 4 records combine together as a single row also shows their start time and end time. Then you can see diff between ID-4 and ID-5 is greater than 15 min so it should display as new row, and so on) How can I acheive above Output with mysql query ?? Please help.. I want to perform a query which returns a subset of the fields in a table. One particular mySQL field is VARCHAR I have a query like this: $query = mysql_query("SELECT * FROM table WHERE code LIKE '3%') ; It's my understanding this should return all values which begin with "3", but it only returns about a dozen of the values 3, 30-39, 300-399, etc. (It works with string fields, but this field contains numerals.) Any help appreciated. thanks, Tom Hello all,
Based on the suggestion of you wonderful folks here, I went away for a few days (to learn about PDO and Prepared Statements) in order to replace the MySQLi commands in my code. That's gone pretty well thus far...with me having learnt and successfully replaced most of my "bad" code with elegant, SQL-Injection-proof code (or so I hope).
The one-and-only problem I'm having (for now at least) is that I'm having trouble understanding how to execute an UPDATE query within the resultset of a SELECT query (using PDO and prepared statements, of course).
Let me explain (my scenario), and since a picture speaks a thousand words I've also inlcuded a screenshot to show you guys my setup:
In my table I have two columns (which are essentially flags i.e. Y/N), one for "items alreay purchased" and the other for "items to be purchased later". The first flag, if/when set ON (Y) will highlight row(s) in red...and the second flag will highlight row(s) in blue (when set ON).
I initially had four buttons, two each for setting the flags/columns to "Y", and another two to reverse the columns/flags to "N". That was when I had my delete functionality as a separate operation on a separate tab/list item, and that was fine.
Now that I've realized I can include both operations (update and delete) on just the one tab, I've also figured it would be better to pare down those four buttons (into just two), and set them up as a toggle feature i.e. if the value is currently "Y" then the button will set it to "N", and vice versa.
So, looking at my attached picture, if a person selects (using the checkboxes) the first four rows and clicks the first button (labeled "Toggle selected items as Purchased/Not Purchased") then the following must happen:
1. The purchased_flag for rows # 2 and 4 must be switched OFF (set to N)...so they will no longer be highlighted in red.
2. The purchased_flag for row # 3 must be switched ON (set to Y)...so that row will now be highlighted in red.
3. Nothing must be done to rows # 1 and 5 since: a) row 5 was not selected/checked to begin with, and b) row # 1 has its purchase_later_flag set ON (to Y), so it must be skipped over.
Looking at my code below, I'm guessing (and here's where I need the help) that there's something wrong in the code within the section that says "/*** loop through the results/collection of checked items ***/". I've probably made it more complex than it should be, and that's due to the fact that I have no idea what I'm doing (or rather, how I should be doing it), and this has driven me insane for the last 2 days...which prompted me to "throw in the towel" and seek the help of you very helpful and intellegent folks. BTW, I am a newbie at this, so if I could be provided the exact code, that would be most wonderful, and much highly appreciated.
Thanks to you folks, I'm feeling real good (with a great sense of achievement) after having come here and got the great advice to learn PDO and prepared statements.
Just this one nasty little hurdle is stopping me from getting to "end-of-job" on my very first WebApp. BTW, sorry about the long post...this is the best/only way I could clearly explaing my situation.
Cheers guys!

Hi, after following lots of advice and changing to MySqli I am running into a few probs. This is me just probably missing something stupid, I know what I want, but can't figure out what query I should use and where I should place it. All the queries I have tried have failed.
I just need a query that gets the $current_stored_password from the password field on the database, to confirm the last check
elseif
($current_password !== $current_stored_password) {
include 'includes/overall/header.php';
echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';
include 'includes/overall/header.php';
}
Here is the whole script.
<?php
session_start();
error_reporting(0);
//ini_set('display_errors', '1');
require( 'database.php' );
$username = $_SESSION['loggedinuser'];
$current_stored_password = $_SESSION['password'];
$current_password = $_POST['current_password'];
$password = mysqli_real_escape_string($con, md5( $_POST['password']));
$password_again = mysqli_real_escape_string($con, md5( $_POST['password_again']));
// Run checks
if (isset($_POST['current_password'], $_POST['password'], $_POST['password_again'])) {
if( strlen( $_POST['current_password'] ) < 8 )
{
include('includes/overall/header.php');
echo "Password Must Be 8 or More Characters.";
include('includes/overall/footer.php');
}
elseif( strlen( $_POST['password'] ) < 8 )
{
include('includes/overall/header.php');
echo "Password Must Be 8 or More Characters.";
include('includes/overall/footer.php');
}
elseif
( strlen( $_POST['password_again'] ) < 8 )
{
include('includes/overall/header.php');
echo "Password Must Be 8 or More Characters.";
include('includes/overall/footer.php');
}
elseif
($password !== $password_again) {
include 'includes/overall/header.php';
echo ' Password and password again do not match';
include 'includes/overall/header.php';
}
elseif
($current_password !== $current_stored_password) {
include 'includes/overall/header.php';
echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';
include 'includes/overall/header.php';
} else {
// Define a query to run
$query = "UPDATE `user` SET `password` = '$password' WHERE `username` = '$username'";
// Query the database
$result = mysqli_query($con,$query);
// Check if the query failed
if( !$result )
{
die('There was a problem executing the query ('.$query.'):<br>('.mysqli_errno($con).') '.mysqli_error($con));
}
else {
include 'includes/overall/header.php';
echo 'Password has been changed';
include 'includes/overall/footer.php';
}
}
}
// Close the connection
mysqli_close($con);
?>
At the moment the message displayed when the form is submitted is
echo $current_password . ' AND ' . $_POST['current_password'] . ' Password and password again do not match';How do I retrieve the password from the database to compare against the current password entered by the user? Any help is much appreciated. PS. Yes I know I have repeated code and that md5 is not secure, but I am just building onto a template I got and will be making changes to shorten the code and secure the password soon What would be the correct way to close a mysql query? At current the second query below returns results from the 1st query AND the 2nd query The 3rd query returns results from the 1st, 2nd and 3rd query. etc etc. At the moment I get somthing returned along the lines of...

I have a query that gives me results. What I need to do is take those results and, I think, use php to compare the results and add a 1 to the correct section. Example: 3 tables table name- retail_sales id sales_id amount week table name- online_sales id sales_id amount week table name- sales_person sales_id name I have the query that breaks down results by week: week 1 | retail_sales.amount | online_sales.amount What I need is some php code that will then compare the two together and: if retail_sales.amount > online_sales.amount +1 to retail OR if retail_sales.amount < online_sales.amount +1 to online so you would end up with a result like a sports record (6-2) Any ideas Thank you for any help If ($_GET['CODE'] == '1') { $ThreadID = mysql_escape_string($_GET['threadid']); $ForumID = mysql_result(mysql_query("SELECT forum_id FROM ".FORUM_THREADS."

(`user_id`, `thread_id`, `post_text`, `forum_id`, `ip_address`, `timestamp`) VALUES ('{$memid}', '{$ThreadID}', '', '{$ForumID}', '{$IP}' , CURRENT_TIMESTAMP) This is the only query that does this part of the code and I can't see why it is adding 2 queries. FORUM_POSTS = constant containing table name. Hi, say I have a query like so: foreach($_REQUEST['r'] as $position => $row) { $row = implode("', '",$row); $result = mysql_query("Insert into player_stats (position,shirt_number,player_id,goals,cards,substituted,used_sub,injury,season,report_id) values('$position','$row','$currentSeason','$report_id')"); } How do I print the results of that query to my Browser for each time? Thanks Hi all, I'm new to php and I was trying to send the results of one query to another query. I need the results of both queries. Here are the queries $cui1 = mysql_query("SELECT DISTINCT CUI FROM MRSTY WHERE STY='ABC' "); $cui2 = mysql_query("SELECT DISTINCT CUI FROM MRSTY WHERE STY='XYZ' "); I want to know if this is possible $cuis = mysql_query("SELECT CUI1,CUI2,REL FROM MRREL WHERE CUI1 IN $cui1 OR CUI1 IN $cui2 "); Thanks. Code: [Select] $PlayerQuery = "SELECT FirstName, SurName FROM players p, rounds m, entrants e, games t WHERE p.PlayerID = e.PlayerID AND m.GameID = '$ID' AND e.EntrantID = m.Player"; $PlayerResult = mysql_query($PlayerQuery); $PlayerRow = mysql_num_rows($PlayerResult); Can someone suggest why this returns game*the number of results. For each new game it returns an extra duplicate result. For example for 2 games: j Smith j Smith t John t John etc There are no duplicate entry's! and results should be unique. Not in a loop (positive) Hello all, I am new here so thank you in advance for all of your help. I am writing a pretty simple search script to display data from a table however have run into a snag. Things seem to get complicated all by themselves. I have a drop down to select the predetermined search criteria, because the data has either a 'Y'es or 'N'o. For example there are 50 or so products/brands with ingredients/categories in them. i.e. Brand X contains Sugar=Y, Salt=Y, Vinegar=N Brand Y contains Sugar=N, Salt=N, Vinegar=N Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y Brand A contains Sugar=N, Salt=N, Vinegar=Y I want to display the brands that contain only the selected ingredients. I have added check boxes for the user to select. This runs ok however the return is more of a broader result and requires too much interpretation from the user. i.e. If I want to know which brands contain only salt and vinegar ??BRAND??= Sugar=N, Salt=Y, Vinegar=Y or ??BRAND??= Salt=Y, Vinegar=Y The return comes back: Brand X contains Sugar=Y, Salt=Y, Vinegar=N Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y Brand A contains Sugar=N, Salt=N, Vinegar=Y Ideally the return Should only be: Brand Z contains Sugar=Y, Salt=Y, Vinegar=Y I believe the else if statement would work, I just have no knowledge of where to put it or how it would work. Any suggestions would be greatly appreciated. Hello, This is query in MySQL Quote mysql> LOAD DATA LOCAL INFILE '/var/www/html/numbers.csv' INTO TABLE details FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' (number); Query OK, 0 rows affected (0.00 sec) Records: 2200 Deleted: 0 Skipped: 1200 Warnings: 0 Now, I am trying to run the same query in PHP and display the same results....

For example if I have 10 records each with a unique id, is there anyway I can get all of the records except record 5? Thanks for any help. this is my query code Code: [Select] <?php $wsi_query = "(SELECT * FROM (SELECT a.no_Yards AS 'yards', a.Day_Swam AS 'date', a.Season AS 'season', (SELECT sum(no_yards) FROM swimming WHERE Season = '$ws') AS 'totalyards', (SELECT AVG(no_Yards) FROM swimming WHERE Season = '$ws') AS 'avg', (SELECT count(*) FROM swimming WHERE Season ='$ws') AS 'timelaps', (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards > a.no_Yards AND Season = '$ws') AS hrank, (SELECT 1 + count(*) FROM swimming b WHERE b.no_Yards < a.no_Yards AND Season = '$ws') AS lrank FROM swimming AS a) AS x WHERE Season = '$ws' )"; $wsi_result = mysql_query($wsi_query) or die("Query failed ($wsi_query) - " . mysql_error()); $wsi_row = mysql_fetch_assoc($wsi_result); ?> what it should do is output both the min and the max values like this Code: [Select] <?php while ($mm_wsi_row = mysql_fetch_assoc($wsi_result)){ if ($mm_wsi_row['hrank'] == 1){ if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];} echo "<tr>"; echo "<td style='background-color:#F90'>Max Length:</td>"; echo "<td>" . number_format($mm_wsi_row['yards']) . "</td>"; echo "<td>" . $dayswam . "</td>"; echo "</tr>"; } if($mm_wsi_row['lrank'] == 1){ if ($mm_wsi_row['date'] == "0000-00-00"){$dayswam = "";}else{$dayswam = $mm_wsi_row['date'];} echo"<tr>"; echo "<td style='background-color:#F90'>Min Length:</td>"; echo "<td style='background-color:#FF9'>". number_format($mm_wsi_row['yards']) . "</td>"; echo "<td style='background-color:#FF9'>" . $dayswam . "</td>"; echo "</tr>"; } ?> the problem is that it doesn't work right all the time for some it just shows the min while others it just shows max I've tested the query in MySQL workbench so i know that that is working right but idk why it works right for some and doesn't work for others |
