I am creating a table that creates many rows based on what is in the equipment table. There is a second table that has information pertaining to an order that has already been made. equipment table is as follows: equipment_id equipment_name 1 Book 2 Dog 3 cat 4 hat equipment order table is as follows: job_id equipment_id equipment_quantity 10 1 100 10 3 100 There are 20 things in the equipment table. When the page loads, i would like it to show all of the items from the equipment table but i would like the rows where there is a quantity defined in the equipment_order table to be populated. So i should see Eauipment Quantity Book 100 Dog cat 100 hat The sql that i have used is this SELECT a.equipment_id, equipment_name, equipment_category, b.equipment_quantity FROM ssm_equipment a LEFT JOIN ssm_equipment_order b ON a.equipment_id = b.equipment_id Quite rightly this select anything with a quantity regardless of whether it relates to the current job or not. I have a variable $current_job_id that needs to be used to only get the values for the current job I tried the following SELECT a.equipment_id, equipment_name, equipment_category, b.equipment_quantity FROM ssm_equipment a LEFT JOIN ssm_equipment_order b ON a.equipment_id = b.equipment_id WHERE $current_job_id = 10 but this only get the rows where the ids match. I tried moving the WHERE clause but i cant seem to figure this out with out getting many errors. I have also tried the followin to no avail. SELECT a.equipment_id, equipment_name, equipment_category, b.equipment_quantity, b.job_id FROM ssm_equipment a LEFT JOIN ssm_equipment_order b ON a.equipment_id = b.equipment_id where b.job_id = '24' or b.job_id='NULL' The above just shows row with 24 I have talked about this in another thread but as this is very different to the origional question, i have moved it. Origional questions is below

Hi I am trying to demonstrate a random number college project by code. I have a query which works fine getting data from table: SELECT id,Date, GROUP_CONCAT(ball ORDER BY ball) balls FROM ( SELECT id,Date,Ball1 ball FROM history eh UNION SELECT id,Date,Ball2 ball FROM history eh UNION SELECT id,Date,Ball3 ball FROM history eh UNION SELECT id,Date,Ball4 ball FROM history eh UNION SELECT id,Date,Ball5 ball FROM history eh ) x WHERE ball IN (6, 24, 32, 48, 50) GROUP BY id HAVING COUNT(*) >= 2 This will give 3 columns result: id,Date,balls which match any 2 or more of above numbers I want to join the result with another table starballs which has the same id as above and stores two colums of data Star1 Star2 i.e. id,Star1,Star2 I assume this will be inner join? to keep the data of top query and join it with starballs table. I have tried all sorts and cannot get it working. Can someone help me with this please. Thanks

Basically i want to match 2 columns from table1 to 1 column in table2. Here's my code. How do I do the joins properly? $get_earnings = $db->prepare("SELECT users.*, member_earnings.* FROM member_earnings LEFT JOIN users ON member_earnings.sent_by = users.user_id LEFT JOIN users ON member_earnings.guest_id = users.user_id WHERE record_id = :record_id AND status = :status ORDER BY earning_id DESC LIMIT 20"); $get_earnings->bindParam(':record_id', $url_id); $get_earnings->bindValue(':status', 1); $get_earnings->execute();

Hi, Here is my SQL, its build with a loop, and looks correct to what I think it should be. I believe the output "$data" below should only be 4 records.. though its a lot more, and some data is duplicated and shown twice in the array. Lot of stuff removed for simplicity. SELECT usr.usr_login, app.app_name, acs.acs_read, acs.acs_add, acs.acs_edit, acs.acs_delete, acs.acs_admin FROM acs LEFT JOIN usr ON usr.ID = usr.ID LEFT JOIN app ON app.ID = app.ID if it matters here's the code that generated the statement above from an array. <?php // ===================================================================================================== // preperation // ===================================================================================================== foreach($fldarray as $fld){ // get readable names and stick em into an array $nm[] = $fld['human']; // Field name, and joins (if the join is using the option table) if($fld['opt'] == 1 and ($fld['opt_table'] == "" or $fld['opt_field'] == "")){ $jn[] = array('table' => "opt", 'field' => "opt_value"); $fd[] = "opt.opt_value"; // Field name, and joins (if the join is using a table other than options) }elseif($fld['opt'] == 1 and ($fld['opt_table'] <> "" and $fld['opt_field'] <> "")){ $jn[] = array('table' => $fld['opt_table'], 'field' => $fld['opt_field']); $fd[] = $fld['opt_table'].".".$fld['opt_field']; // a field directly written no foreign keys.. }else{ $fd[] = $ap.".".$fld['fieldname']; } $sa[] = array('human' => $fld['human'], 'field' => $fld['fieldname'], 'opt_table' => $fld['opt_table'], 'opt_field' => $fld['opt_field']); } // ===================================================================================================== // Start building the SQL // ===================================================================================================== $sql = "SELECT ".implode(", ", $fd)."

This seems like something I've done several times a year for years, but I can't seem to get it. I can't find a solution on Google that works, although the question was asked many times and answered, too. Also, I'm low on sleep right now. Let's say I have two tables: USERS USERS_LOGINS I want to join the tables and get one row per user, with only the latest login row. Assume "UserId" is the pk/fk and there's some sort of LoginTime in the USERS_LOGINS table. So I will get results like: - Brian 8/4 - Mitch 8/3 - Jerry 8/2 I appreciate the help.

I've got two tables user table - id - username - fname - lname - group_id event Table - id - user_id - event_time - event_date - event ('Arrival','Departure','Break',etc..) My problem is getting all user by group and joining other table even date, but it should be base on 'event_date' I use `LEFT JOIN` and `LEFT OUTER JOIN` but because I have to specify the `event_date` not all user can be shown because some are absent. I made this SELECt * FROM user as u LEFT OUTER JOIN event as e ON u.id = e.user_id WHERE u.group_id = 6 AND ( e.event_date = '2016-07-05' AND e.event = 'Arrival' ) GROUP BY u.id but it only show the user who has an event on the date specified. I tried to make an VIEW table but it still has the condition base on event_date. Although I made this on PHP by condition but it takes time to load as I select event on every user. is there a way to get it using SQL? it should be like this:

I want to fetch the titles from the Courses table, but I only want the Course Title to return once when I join Events. Courses CID | CourseTitle 1 | Course A 2 | Course B 3 | Course C Events EID | CID | EventDate 1 | 1 | 2016-02-22 2 | 1 | 2016-02-23 3 | 2 | 2016-02-24 4 | 3 | 2016-02-25 5 | 3 | 2016-02-26 If I use a JOIN, SELECT Courses.CourseTitle FROM Courses LEFT JOIN Events on (Events.CID = Courses.CID) then I get Course A Course A Course B Course C Course C But what I want is Course A Course B Course C Because ultimately, I'm going to select an Event date range, and I want to see just the courses with the event date range. Thanks!

Hello all. I dont know how to go about this. I have a table (Transactions) that contains transactions of users. Another table (Confirmed) contains details of every confirmed user. I want to do a select statement that will display all the confirmed user with only the last of their transaction. But so far all it does is replicate the user and their date of transaction and that is not what i want. My intention is to get something like: Firstname Surname Date Registered Last Transaction andrews john 12-12-2014 10-10-2015 doe andy 12-12-2010 12-12-2014 But i'm getting something like: Firstname Surname Date Registered Last Transaction andrews john 12-12-2014 10-10-2015 andrews john 12-12-2014 10-11-2015 doe andy 12-12-2010 12-12-2014 doe andy 12-12-2010 01-12-2014 doe andy 12-12-2010 12-12-2013 Thanks $stm=$pdo->query("select * from confirmed left join transaction on confirmed.user_id = transaction.user_id where confirmed.status='confirmed' order by date"); while($row = $stmt->fetch(PDO::FETCH_ASSOC)) { echo $row['firstname']; echo $row['surname']; echo $row['regDate']; echo $row['lastTrans']; }

Hello. I'm trying to get this piece of code finished but it's not going my way, if anyone could help me out that would be great. Here whats I'm trying to do: Table1 Table2 ---------------- --------------------------------- ID | | PlayerID | PlayerName | ---------------- -------------------------------- 1393 | | 1393 | Player1 | 2097 | | 2097 | Player2 | 3888 | | 3888 | Player3 | 3888 | | 4017 | Player4 | 3888 | --------------------------------- 4017 | 4017 | 4017 | ---------------- I Want to Count the entries in Table1 (3888 has 3 entries so it will display like "3888: 3") Then I want to join Table1 and Table2 using the ID so I can get the players name (3888=Player3 so it would display like Player3 : 3) Here's the code I'm using: <?php //connect to db $query = "SELECT * FROM Table1 INNER JOIN Table2 WHERE Table1.PlayerID = Table2.ID"; $query2 = "SELECT ID, SUM(ID=0) AS n0, SUM(ID=1) AS n1, COUNT(*) AS total FROM Table1 GROUP BY ID"; $result = mysql_query($query) or die($query."<br/><br/>".mysql_error()); $result2 = mysql_query($query2) or die($query2."<br/><br/>".mysql_error()); echo "<table border='1'> <tr> <th>PlayerName</th> <th>Entries</th> </tr>"; while($row2 = mysql_fetch_array($result2)) while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['ID'] . "</td>"; echo "<td>" . $row['PlayerName'] . "</td>"; echo "<td>" . $row2['Total'] . "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($link); ?> If I use $query on its own it joins perfectly, If I use $query2 on its own, it displays the results exactly how I want them listed but with the ID instead of the PlayerName, I tried putting them both together as shown above but I can't get them to work together. What I want my end Result to be Player1 1 Player2 1 Player3 3 Player4 3 How it keeps coming out; 1393 1 2097 1 3888 3 4017 3 Can anyone see where I'm going wrong? Thank you!!

I have a question about how I would structure a query. I have 2 tables. Store store_id -- primary key zip_code Merchandise item_id -- primary key item_name description cost storeID -- foreign key that references the store_id from the store. I am using InnoDB. I want the user to be able to input 1-5 choices that are 1 word apiece and it would cross reference the decription and tell me the store that has them both. For instance, choice 1 = clock, choice 2 = paper, and choice 3 = food. It would query a result that would give me the stores that have items that match the description of them all. For instance, it would return Wal - Mart based on this query because it would be the only store that had an item to match each description. Any help is much appreciated. Thanks!

I have data similar to below. I am doing a MySQL query and doing a JOIN based on instructor name. I am echoing classes and linking the instructor name to another page with their BIO. All is working great, however I want to use the ID's for something else. How do I differentiate the ID between the Instructors table and the Classes Table without changing the column name in the database? For instance, I want to echo the Instructor ID and then echo the Classes ID, but they are both the same column name in the database and since they are joined, how will that work? Instructors: ID | Instructor | Title | Bio | 1 | Bob Smith | Chef | bob smith is a chef with... | 2 | Jane Doe | Professor | Jane doe is an instructor that... | Classes: ID | Instructor | Class Title | Class Description | 4 | Bob Smith | Baking | this is a baking class where you learn.... | 5 | Jane Doe | Food Safety | Food safety is very important... |

I have two tables 'book' and 'category'. They look like the following in phpmyadmin; book id title author category isbn ---- ------- ---------- ---------- ------- 1 Treasure Chest Jim Jones 1 14252637 2 Pirates Boat Sue Smith 2 88447737 3 Adventure Land Harry Jo 3 01918273 4 Winter Week Sam Dill 3 00999337 5 The Twite Roald Dahl Fiction 87873366 category id cat_name ---- ------- 1 Horror 2 Kids 3 Fiction 4 Science Users have the option of adding books into the library via an online form, or via a Google Booka api method (user enters isbn, searches, is presented with book info and then clicks 'add to library', done.). This is handled via ajax. The online form works fine, and successfully adds the book info. However my problem is with the Google Books method, it successfully adds the data to the db however the category column is in text format (i.e 'Juvenile Science' or 'Scary Fiction') as opposed to the manual form which adds categories as 1, 2 or 3 (1 =Horror, 2 = Kids, 3 = Fiction). Is there any way I can add the Google Book category data to my table and convert it to an integer or similar? Not sure what I need to do. Suggestions appreciated! Should I add the Google entries to another table (i.e googleCategory)? My HTML only outputs the numbered category entries and ignored the text format entries. my php $sql = "SELECT b.id, b.title, b.author, b.isbn, b.publicationYear, c.cat_name FROM book AS b INNER JOIN category AS c ON b.category = c.id WHERE status != 'Archive' ORDER BY id DESC LIMIT $startrow, 15 "; $res = $conn->query($sql) or trigger_error($conn->error."[$sql]"); while($row = $res->fetch_array()) { echo '<tbody>'; echo '<tr>'; echo '<td>' . $row['id'] .

Hello guys. Thanks a lot for any help with this. My problem is that I'm trying to use MAX to get the last item in the portafolio table. This is my query: $result = $db->prepare( "SELECT * FROM portafolio INNER JOIN imagenes ON imagenes.work = portafolio.idp WHERE work = ? ORDER BY iid DESC); $result->execute(array($_GET['work'])); The main idea is not use $_GET['work'], because i want to display the last work (with their respective images) in my portafolio in the main page, so im not passing any variable by url.

Hello. I' have a Table in MySQL That stores data (name/email/time) of when a person last run X script. I'm trying to pull that information for each user unique to their account to display so they know that they've already ran that script today How it works. Run script > Create's Row storing the data > MySQL Events deletes row after 24 hours.

I thought I had this issue figured out last night with the help from this forum, but turns out it still isn't working as expected. I have two tables: Table: sapImport id invoiceNo invoicedAtID invoicedAtName soldOn soldBy customer 1 CICIN123 3 Cicero 1384832632 brian john smith 2 DESTIN12 5 Destiny 1384832632 brian Henry Will 3 VESTIN32 3 Cicero 1384832632 jason Peter Jenn Table: conStatus id store record statusCode 34 3 1 0 35 5 3 0 39 3 1 15 I do have more rows than this, but i'm just trying to give an idea ... I currently have the following query: SELECT * FROM sapImport si INNER JOIN conStatus cs ON si.id = cs.record INNER JOIN ( SELECT record, MAX(id) as id FROM conStatus GROUP BY record ) mx ON cs.record = mx.record AND cs.record = mx.id WHERE cs.store='$storeID' AND cs.statusCode < '998' Basically, the table sapImport contains customer information and the conStatus table contains all interactions with a record in the sapImport table. The 'id' row in sapImport is the primary key and is auto-incremented. The 'record' row in conStatus references the 'id' row from sapImport. I need a query that pulls the LAST record (from conStatus) for a particular customer (from sapImport) where the store=x and the statusCode is less than 998. I should only get ONE result set with this. Any help will be GREATLY appreciated! Thanks in advance!

Hi! I have 2 tables (See attached image). I want to select all(') from the table variables, but I only want to get data where variables.ID doesn't exist in table translations.ID. okey! So if the variables-ID does not exist in the table-translation:Variable, den I want to get it. Also, there must have to be a where statement so I can choose too fetch variables with language (id) 3, or another integer. I want this because I want to select all variables which hasn't been used in the translation table. I have tried with innerjoin... and actually I have never used joins before, never had too. But now I think I have to, but my innerjoin didn't worked. And because of my understanding in joins is small, I also tried left and right join but I din't get it too work. It would by my knowledge be something like this. SELECT variables.* FROM variables INNER JOIN translations ON variables.id != translations.id WHERE language = 3 But no.. I only get all variables even if the variable ID is in the translation.variable table. Thanks in advance! I guess this is simple for you guys.

I am having trouble writing exactly 4 queries in mysql. Here is the view I am using for queries: http://pastie.org/8403299 Here is the Raw Data you can check http://goo.gl/z7Vv9X which you can check. What is needed: 1) Gained students are those who exist in the selected / filtered month and don't exist in the previous month. 2) Lost students are those who exist in the previous month of the selected / filtered month and don't exist in the selected / filtered month. 3) Get a list of all lost students since the start of the center till now(). 4) Get a list of all gained students since the start of center till now. I am currently stuck with query 1) (Gained students are those who exist in the selected / filtered month and don't exist in the previous month.) I have written it like that (see just below), but I get the same number of rows back if I haven't filtered anything... uff. SELECT * FROM lessons_master_001 my1 WHERE NOT EXISTS ( SELECT 0 FROM lessons_master_001 my2 WHERE my1.student_id = my2.`student_id` AND my1.teacher_id = my2.teacher_id AND my1.`student_payment_id`= my2.`student_payment_id`AND CONCAT(CAST(MONTH(DATE_ADD(my1.Lesson_Booking_Date, INTERVAL -1 MONTH))AS CHAR(20)),CAST(YEAR(DATE_ADD(my1.Lesson_Booking_Date, INTERVAL -1 MONTH))AS CHAR(20))) = CONCAT(CAST(MONTH(my2.`Lesson_Booking_Date`)AS CHAR(20)),CAST(YEAR(my2.`Lesson_Booking_Date`)AS CHAR(20))) ) My logic is like this so I take everything from the view lessons_master_001 and give alias my1 and in the NOT EXISTS clause I am giving to the same dataset alias my2, then join those ID's that are also used in view lessons_master_001 and then try to connect previous month from data set my1 with current month from data set my2. I am using DATE_ADD function to subtract month from current date and practically get date - 1 month. I would really appreciate any help you will provide, cause I lost 2 days already on it with no progress in front. Thank you in advance.

Below is my query: <?php if (isset($_POST['search_all_submit'])){ $search_all = strtolower($_POST['search_all']); echo "<table id='qbook'>"; echo "<tr>"; echo "<td> CID </td>"; echo "<td> Company </td>"; echo "<td> Property </td>"; echo "<td> Contact </td>"; echo "</tr>"; $sql = " SELECT contract.*, customer.*, contact.* FROM customer INNER JOIN contract ON customer.customer_id = contract.customer_id INNER JOIN contact ON customer.customer_id = contact.customer_id WHERE customer.company_name like '%".$search_all."%' or customer.billing_address like '%".$search_all."%' or contract.prop_name like '%".$search_all."%' or contract.prop_address like '%".$search_all."%' or contact.contact_fname like '%".$search_all."%' or contact.contact_lname like '%".$search_all."%' "; $results = mysql_query($sql)or die(mysql_error()); while ($row = mysql_fetch_array($results)){ $company_name = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['company_name']))); $billing_address = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['billing_address']))); $prop_name = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['prop_name']))); $prop_address = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['prop_address']))); $fname = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['contact_fname']))); $lname = implode('<span class="high">'.$search_all.'</span>',explode($search_all,strtolower($row['contact_lname']))); $CID = $row['CID']; echo "<tr>"; echo "<td> $CID </td>"; echo "<td> $company_name <br /> $billing_address </td>"; echo "<td> $prop_name <br /> $prop_address </td>"; echo "<td> $fname $lname</td>"; echo "</tr>"; } echo "</table>"; } ?> The query above gives me results like: 10008 | jw property management | creekside crossing | mike pudelek | 4816 green bay rd | 9219 66th ave | 10008 | jw property management | creekside crossing | sam johnson | 4816 green bay rd | 9219 66th ave | 10008 | jw property management | creekside crossing | dean zierk | 4816 green bay rd | 9219 66th ave | What I would like to see is: 10008 | jw property management | creekside crossing | dean zierk | 4816 green bay rd | 9219 66th ave | mike pudelek | sam johnson I am pretty sure that I need to use some type of GROUP CONCAT and possibly a GROUP BY. However all of my attemps have failed. Any help would be appreciated.
