Here's what I am trying to do. Users Table user_id, sponsor_id, username, filled_positions, position_1, position_2, position_3, position_4, position_5 1 0 user 1 4 user 2 user 3 user 4 user 5 2 1 user 2 2 user 4 user 5 3 1 user 3 4 2 user 4 5 2 user 5 Above is a "Users" table. Here's what I am trying to do. Insert new users into the table. Say I already have the users table set up with 5 users. I want to add User 6. I want to loop through the users in the table and find the next empty position and update it with the new user id. In this scenario diagram above, the next empty position is Row 1 - position_5. The one after that is Row 2 - position_3 and then Row 2 - position_4...etc. It basically loops through rows and checks each position. So User 6 will be placed under Row 1 - position_5 and User 7 will be placed under Row 2 - position_3. How can one go on about doing that?

Hi Guys, I have a JET SQL query that i need to convert to MYSQL (Appologies too if this is posted in the wrong section.. i never know whether to go PHP or MYSQL!) Im not being lazy.. ive tried for hours but cannot get it to work, it has two depth inner join and a group by with a where (with 1 criteria)... If anyone can help id massively appreciate it and also explain how you got there... SELECT Count(tbl_Items.ItemID) AS CountOfItemID, tbl_LU_Collections.CollectionDesc FROM (tbl_Items LEFT JOIN tbl_LU_Categories ON tbl_Items.ItemCategory = tbl_LU_Categories.ItemCatID) LEFT JOIN tbl_LU_Collections ON tbl_LU_Categories.CollectionID = tbl_LU_Collections.CollectionID WHERE (((tbl_Items.RetailProduct)=-1)) GROUP BY tbl_LU_Collections.CollectionDesc;

firstly, I am not a db programmer. I ply my trade in WordPress stuff, but not in-depth db structuring from scratch. please keep that in mind as I do my best to ask this question? I have made some headway creating two tables that I think will almost, kinda do what I want, which is: Phillips pid1Barnes pid2Moore pid3de Mohrenschildt pid4Oswald pid5 Hunt pid6Sturgis pid7Moore pid3 I've created a (really large) outline in html that simply shows, in effect: Phillips (knows) » Barnes (supervised) » Moore (supervised) » de Mohrenschildt (knows) » Oswald ... AS WELL AS, Phillips (knows) » Hunt (knows) » Sturgis (followed, who also knows) » Moore (same, pid3) ... I put Sturgis followed by Moore specifically to show that these relationships are in no way numerically sequential from the ASSOCS table. There will be 4 or 500 Persons, (and 40 or 50 Organizations, once I get this solved). You can see an example of it here (there's lots of data going on in this outline): http://stemmonsfreeway.com/military-industrial-intelligence-anti-castro-syndicated So, I've come up with these tables: [persons] id, name ----------------- 1 Phillips 2 Barnes 3 Moore 4 de Mohrenschildt 5 Oswald 6 Hunt 7 Sturgis [assocs] p_id, a_id ---------------- 1 2 2 3 3 4 4 5 1 6 6 7 7 3 And I have this query: SELECT a1.p_id, p1.name AS 'Name', a2.p_id, p2.name AS 'FName1', a3.p_id, p3.name AS 'FName2' FROM assocs a1 JOIN assocs a2 ON a1.p_id = a2.a_id JOIN assocs a3 ON a2.p_id = a3.a_id JOIN persons p1 ON a1.p_id = p1.id JOIN persons p2 ON a2.p_id = p2.id JOIN persons p3 ON a3.p_id = p3.id WHERE p1.id = 1 AND p2.id = 2 AND p3.id = 3;which returns: 1 Phillips 2 Barnes 3 Moore *** The problem I have is where a trail ends, Phillips to Oswald, and starts again, Phillips to Hunt to Moore, for instance. *** What I need is a way to define an end to a string of associations and a start of the next one, perhaps with another field or two in the ASSOCS table, or another table... (I'd also love to be able to denote one of a few types of relationships, i.e. "friend" "foe" "supervised" "worked for" ...) *** I'm hoping some kind soul can help me with a query that can do this, and some advice on how to handle it in the tables I've started with...?

Here's what I am trying to do. Retrieve "title" and "slug title" from all the rows in a table. Update them with new "title", "slug title" and "brand name". Here's my query. It updates the table with the brand names for each row. But for some reason, it removes the title and slug title from all the rows in the table. Is there a reason why it's doing that? function getIt($var) { $pos = strpos($var, ' - '); echo(substr($var, $pos+3)."\n"); } if(isset($_POST['submit'])) { $get_record = $db->prepare("SELECT * FROM items"); $get_record->execute(); $result_record = $get_record->fetchAll(PDO::FETCH_ASSOC); if(count($result_record) > 0){ foreach($result_record as $row) { $get_item_id = intval($row['item_id']); $get_item_title = trim($row['item_title']); $get_item_title_slug = trim($row['item_title_slug']); $new_title = getIt($get_item_title); $new_title_slug = Output::createSlug($new_title); $brand_name = substr($get_item_title, 0, strpos($get_item_title, ' - ')); $update_record = $db->prepare("UPDATE items SET brand_name = :brand_name, item_title = :item_title, item_title_slug = :item_title_slug WHERE item_id = :item_id"); $update_record->bindParam(':item_id', $get_item_id); $update_record->bindParam(':brand_name', $brand_name); $update_record->bindParam(':item_title', $new_title); $update_record->bindParam(':item_title_slug', $new_title_slug); if(!$update_record->execute()) { $errors[] = 'There was a problem updating the item.'; } } } else { $errors[] = 'No item found.'; } }

I would like to simplify my request... here is my query SELECT emp_id, ROUND(SUM((Invoice.invoiceTotal-NewQuote.total)*.30),2) AS thirtypercent, ROUND(SUM(NewQuote.total*.20),2) AS twentypercent FROM `NewQuote` INNER JOIN Invoice ON Invoice.quoteID=NewQuote.quoteID INNER JOIN schedules ON schedules.quoteId=NewQuote.quoteID WHERE (rem=1 OR rem=2) AND (schedules.redo IS NULL) AND invoiceTotal!=0 AND (DATE_FORMAT(date_start, '%m/%d/%Y') >= '07/01/2016') AND ((DATE_FORMAT(date_start, '%m/%d/%Y')<='07/31/2016')) GROUP BY emp_id What im aiming here is this line "AND invoiceTotal!=0" should only be used in getting the thirtypercent and should not be applied in getting the twentypercent. Can you help me on how i can do this? Thank you

Hello, I am doing my best to learn mysql but I still have a lot to learn when queries involve loops or complex syntax. Here's what I would like to achieve: Table 1 includes games played since the beginning of the season (where homeTeamScore or awayTeamScore > 0): Table 2 includes predictions made by users as to which team will win each game (gameId in T2 = id in T1): The following query lets me know how many games have been played since the beginning of the season: $query = "SELECT COUNT(`id`) FROM " . SPORTS_BOL_GameDao::getInstance()->getTableName() . " WHERE SeasonID = " . $seasonId . " AND (homeTeamScore > 0 OR awayTeamScore > 0) ORDER BY gametime DESC"; $totalGames = $this->dbo->queryForColumn($query); And this one how many predictions each user has registered: $query = "SELECT COUNT(`g`.`id`) FROM " . SPORTS_BOL_GameDao::getInstance()->getTableName() . " g INNER JOIN " . SPORTS_BOL_PredictionDao::getInstance()->getTableName() . " p ON g.id = p.gameId WHERE g.SeasonID = " . $seasonId . " AND (g.homeTeamScore > 0 OR g.awayTeamScore > 0) AND p.userId = " . $point['userId'] . " ORDER BY g.gametime DESC"; $totalPreds = $this->dbo->queryForColumn($query); First question: how could I combine these two queries into one and get the total number of missing predictions for each user? As an example, if 89 games have been played and user has registered 70 predictions, I would like to get "19" out of the query. Second question, more complex (at least to me!): what would the query look like if I wanted to know how many consecutive games has each user missed since their last prediction? As an example, if my last prediction was registered on gameId "460" and 4 more games have been played since then (id 468, 469, 470 and 471), I would like to get "4" out of the query. Hope this makes sense and is easy to understand! Thank you very much for your support!

So i made a login page, but whenever i enter right, wrong, or no password at all, it always displays wrong password. I've been trying to fix it for hours, but I just can't seem to find the error. It's like it's skipping if the password is right statement and goes straight through the else statment. <?php $connection = mysql_connect("com-db-02.student-cit.local","***","***") or die (mysql_error()); if ($connection) echo "Connection successful"; else echo "Connection failed"; $db = mysql_select_db("TEAM20") or die (mysql_error()); ?> <?php $_SESSION['customeremail'] = $_POST['user']; $_SESSION['password'] = $_POST['password']; function signIn() { session_start(); if(!empty($_POST['user'])) { $query = mysql_query("SELECT * FROM customer where customeremail = '$_POST[user]' AND password = '$_POST[password]'"); $row = mysql_fetch_array($query); if(!empty($row['customeremail']) AND !empty($row['password'])) { $_SESSION['customeremail'] = $row['customeremail']; getCustDetails(); echo "Successfully login to user profile page.."; echo "<a href=userlogin.php>Profile</a>"; } else { echo "Sorry... YOU ENTERED WRONG ID AND PASSWORD"; echo "<a href=login.html>Try Again</a>"; } } } function getCustDetails() { $queryId = mysql_query("SELECT customerID, firstname FROM Customer WHERE customeremail = '$_POST[user]'"); while($rowId = mysql_fetch_array($queryId)) { $_SESSION['customerID'] = $rowId['customerID']; $_SESSION['firstname'] = $rowId['firstname']; } echo "Code: ".$_SESSION['customerID']; echo "Name: ".$_SESSION['firstname']; } if(isset($_POST['submit'])) { signIn(); } ?>

Hi Mate, i need help with my mysql query.. SELECT * FROM `schedules` WHERE `clientID`=''; it doesn't select any values having an empty clientID... there are rows on my database that i need to select that has an empty clientID and using this statement does not return any value... but if i use `clientID`!='' it works fine, it returns all the data having clientID. Any help is highly appreciated. Thank you in advance. Neil

I'm currently using a external module from an opencart vendor on my opencart store, however I keep getting a error stating mysql has gone away. Thinking this might be an issue with the mysql wait time setting I contacted my server support team and asked them to investigate, below is there answer. I'm struggling to understand exactly why the query is so badly designed as stated below, any advice on the subject would be greatly appreciated

Hello I have a database with matches for Championship and want to display a list of upcoming matches and average number of goals in matches for each of the teams from last 5 matches that they were involved in. E.g. SELECT ko_time, home, away FROM matches_table WHERE ko_time = TODAY will give me something like this. 15:00 Blackburn Rovers Charlton Athletic 15:00 Brentford Preston North End 15:00 Bristol City Reading 15:00 Huddersfield Town Bolton Wanderers 15:00 Hull City Queens Park Rangers Now, I know how to calculate an average number of goals for one team from their last 5 matches e.g. SELECT AVG(home_score + away_score) FROM matches_table WHERE home = "Brentford" or away = "Brentford" ORDER BY match_date DESC LIMIT 5 This will give me average number of goals from 5 last matches of Brentford. Now, I'm not sure how to combine these two queries and have the averages calculated for all teams and displayed like below: 15:00 Blackburn Rovers Charlton Athletic 2.3 2.4 15:00 Brentford Preston North End 1.4 2.3 15:00 Bristol City Reading 2.6 0.9 15:00 Huddersfield Town Bolton Wanderers 3.6 1 15:00 Hull City Queens Park Rangers 0.8 1.65 The table contains all matches - played and fixtures, which are updated once finished. Has anyone got any ideas? Thank you Attached link to db Database

Good evening, I am working on a query at my office that is joining multiple tables in order to display a User notification (similar to facebook). The notifications are based on user department, access level, and position. I want to display all of the announcements filtered for the user that is in the CWAnnouncement table and the NotificationArchive Table where the NotificationArchive.Active is equal to 1 or if they have not made an entry in the NotificationArchive table. If NotificationArchive.Active is equal to 0 then I do not want it to show up in the query results. So far the user filter works but I am having trouble display the results based on who the user is and whether or not they have an announcement in the NotificationArchive table. I hope this make sense. Help would be greatly appreciated this will be my first major project for this company and I want to do a good job for them.
