  • COUNT issue across multiple tables

    - by Kim
    I am trying to count across 2 tables and I dont see whats wrong with my query yet I get a wrong result. User 2 does not exist in table_two, so the zero is correct. SELECT t1.creator_user_id, COUNT(t1.creator_user_id), COUNT(t2.user_id) FROM table_one AS t1 LEFT JOIN table_two AS t2 ON t2.user_id = t1.creator_user_id GROUP BY t1.creator_user_id, t2.user_id Actual result 1 192 192 2 9 0 Expected result 1 16 12 2 9 0 The result indicate a missing group by condition, but I already got both fields used. Where am I wrong ? Also, can I sum up all users that doesnt exist in table_two for t1 ? Like user 3 exists 21 times in t1, then the results would be: 1 16 12 (users with > 0 in t2 will need their own row) 2 30 0 (user 2=9 + user 3=21 => 30) Its okay for the user Id to be wrong for sum of t1 for all users with 0 in t2. If not possible, then I'll just do two queries.

  • Use concat and maintain length of variable

    - by user1682055
    I'm trying to use concat on some variables. These variables have been declared as chars: declare v_order_date char(10); declare v_quantity char(11); declare v_plant char(100); I have a cursor where I am setting these as some outputs. To call the results, I am setting v_msg as set v_msg := concat( v_msg, '\n', v_order_date, v_quantity, v_plant); However, the result I am getting when I select v_msg is: 2012-01-222501008 Creeping Buttercup but I want to maintain the length of the declared variables in my select that looks like this 2012-01-22 250 1008 Creeping Buttercup Are there any suggestions? Thank you.

  • How to use SQL - INSERT...ON DUPLICATE KEY UPDATE?

    - by Probocop
    Hi, I have a script which captures tweets and puts them into a database. I will be running the script on a cronjob and then displaying the tweets on my site from the database to prevent hitting the limit on the twitter API. So I don't want to have duplicate tweets in my database, I understand I can use 'INSERT...ON DUPLICATE KEY UPDATE' to achieve this, but I don't quite understand how to use it. My database structure is as follows. Table - Hash id (auto_increment) tweet user user_url And currently my SQL to insert is as follows: $tweet = $clean_content[0]; $user_url = $clean_uri[0]; $user = $clean_name[0]; $query='INSERT INTO hash (tweet, user, user_url) VALUES ("'.$tweet.'", "'.$user.'", "'.$user_url.'")'; mysql_query($query); How would I correctly use 'INSERT...ON DUPLICATE KEY UPDATE' to insert only if it doesn't exist, and update if it does? Thanks

  • Resetting AUTO_INCREMENT on myISAM without rebuilding the table

    - by Artem
    Please help I am in major trouble with our production database. I had accidentally inserted a key with a very large value into an autoincrement column, and now I can't seem to change this value without a huge rebuild time. "ALTER TABLE tracks_copy AUTO_INCREMENT = 661482981" Is super-slow. How can I fix this in production? I can't get this to work either (has no effect): myisamchk tracks.MYI --set-auto-increment=661482982 Any ideas? Basically, no matter what I do I get an overflow: SHOW CREATE TABLE tracks CREATE TABLE tracks ( ... ) ENGINE=MYISAM AUTO_INCREMENT=2147483648 DEFAULT CHARSET=latin1

  • Trouble creating stored procedure

    - by MatW
    I'm messing around with stored procedures for the first time, but can't even create a simple select! I'm using phpMyAdmin and this is my SQL: DELIMITER // CREATE PROCEDURE test_select() BEGIN SELECT * FROM products LIMIT 10; END // DELIMITER ; After submitting that, my localhost does some thinking for a loooong time and eventually loads a page with no content called /phpmyadmin/import.php. After reloading phpMyAdmin and trying to invoke the procedure: CALL test_select(); I get a "PROCEDURE doesn't exist" error. Any ideas?

  • Enhancing an 'ORDER BY' clause to judge condition by more than 1 integer

    - by Yvonne
    Hi folks, I have some PHP code which allows me to sort a column into ascending and descending order (upon click of a table row title), which is good. It works perfectly for my D.O.B colum (with date/time field type), but not for a quantity column. For example, I have quantites of 10, 50, 100, 30 and another 100. The order seems to be only appreciating the 1st integer, so my sorting of the column ends up in this order: 10, 100, 100, 30, 50... and 50, 30, 100, 100, 10. This is obviously incorrect as 100 is bigger than 50, therefore both 100 values should appear at the end surely? It seems to me that 100 is only being taken into account as having the '1' value, then it appears before 10 because the system recognises it has another 0. Is this normal to happen? Is there any way I can solve this problem? Thanks for any help. P.S. I can show code if necessary, but would like to know if this is a common issue by default.

  • Normalise this Table?

    - by Abs
    Hello all, I am creating a social bookmarking app. I am having a re-thought of the DB design in the middle of development. Should I normalise the bookmarks table and remove the tag columns that I have into a separate table. I have 10 tags per bookmark and therefore 10 columns per record (per bookmark). It seems to me that breaking the table into two would just mean I would have to do a join but the way I currently have it, its a straight select - but the table doesn't feel right...? Thanks all

  • How to bring out checboxes based on drop down list selection from DB

    - by user2199877
    I got stuck again. Can't overcome this step: loop through (in a form of checkboxes) pallets based on the lot drop down list selection, so it can be further submitted to complete the table. Please, please help. So, basically, first submit button (drop down menu) brings into the table lot number and description and also checkboxes to choose pallets. Second submit button (checboxes) brings into the table pallets numbers and weights. Thank you for any help. <?php mysql_connect('localhost','user',''); mysql_select_db('base'); $query="SELECT DISTINCT lot_number FROM pl_table"; $result=mysql_query($query); ?> <form action="" method="POST"> <select name="option_chosen"> <option>-- Select lot --</option> <?php while(list($lot_number)=mysql_fetch_row($result)) { echo "<option value=\"".$lot_number."\">".$lot_number."</option>"; } ?> </select> <input type='submit' name='submitLot' value='Submit' /> </form> <!-- need help here <h4>-- Select pallets --</h4> <form action="" method="POST"> <input type='submit' name='submitPal' value='Submit'/> </form> --> <table border="1" id="table"> <tr> <th width=80 height=30>Lot<br/>number</th> <th width=110 height=30>Description</th> <th width=90 height=30>Pallet<br/>number</th> <th width=60 height=30>Net</th> <th width=60 height=30>Gross</th> </tr> <?php if($_SERVER['REQUEST_METHOD'] =='POST') {$option_chosen=$_POST['option_chosen']; $query="SELECT * FROM pl_table WHERE lot_number='$option_chosen'"; $run=mysql_query($query); $row=mysql_fetch_array($run, MYSQLI_ASSOC); echo "<tr><td>".''."</td>"; echo "<td rowspan='5'>".$row['descr']."</td>"; echo "<td><b>".'Total weight'."<b></td>"; echo "<td>".''."</td><td>".''."</td></tr>"; echo "<td>".$row['lot_number']."</td>"; echo "<td colspan='3'>".''."</td>"; //This to be echoed when "select pallets" submited //echo "<tr><td>".$row['lot_number']."</td>"; //echo "<td>".$row['pallet_number']."</td>"; //echo "<td>".$row['net']."</td><td>".$row['gross']."</td></tr>"; } ?> </table> the table +--------------------------+-------------------------+---------+-------+ | id | lot_number | descr | pallet_number | net | gross | +--------------------------+-------------------------+---------+-------+ | 1 | 111 | black | 1 | 800 | 900 | | 2 | 111 | black | 2 | 801 | 901 | | 3 | 111 | black | 3 | 802 | 902 | | 4 | 222 | white | 1 | 800 | 900 | | 5 | 222 | white | 2 | 801 | 901 | | 6 | 222 | white | 3 | 802 | 902 | +--------------------------+-------------------------+---------+-------+

  • How do I get the median/mode/range of a column in SQL using Java?

    - by Derek
    I have to get the median, mode and range of test scores from one column in a table but I am unsure how to go about doing that. When you connect to the database using java, you are normally returned a ResultSet that you can make a table or something out of but how do you get particular numbers or digits? Is there an SQL command to get the median/mode/range or will I have to calculate this myself, and how do you pull out numbers from the table in order to be able to calculate the mode/median/range? Thanks.

  • While loop in foreach loop not looping correctly

    - by tominated
    I'm trying to make a very basic php ORM as for a school project. I have got almost everything working, but I'm trying to map results to an array. Here's a snippet of code to hopefully assist my explanation. $results = array(); foreach($this->columns as $column){ $current = array(); while($row = mysql_fetch_array($this->results)){ $current[] = $row[$column]; print_r($current); echo '<br><br>'; } $results[$column] = $current; } print_r($results); return mysql_fetch_array($this->results); This works, but the while loop only works on the first column. The print_r($results); shows the following: Array ( [testID] => Array ( [0] => 1 [1] => 2 ) [testName] => Array ( ) [testData] => Array ( ) ) Can anybody shed some light? Thanks in advance!

  • Oracle access from iOS

    - by Michael Lowman
    I'm developing an iPad app that needs read-only access to an Oracle database. Is there any way to do this? As far as I can see, the only options are using OCI, which requires a prebuilt binary in the form of the instant client (and not built for ARM), or OJDBC drivers. Both of these seem to be out of the question. In my research I have discovered that libmysqlclient compiles for arm with minimal tuning. This is a stretch, but is there any possible way to use this to my advantage? I have seen this product providing odbc connectivity through the use of a Windows gateway machine using the ODBC client libraries, but this solution really isn't an option for me at the present time. Any ideas?

  • Returning multiple aggregate functions as rows

  • How to check with PHP does a SQL database already have

    - by Dan Horvat
    I've tried to find the answer to this question but none of the answers fit. I have two databases, one has 15.000.000 entries and I want to extract the necessary data and store it in a much smaller database with around 33.000 entries. Both databases are open at the same time. Or at least they should be. While having the big database open and extracting the entries from it, is it possible to check whether the value already exists in the smaller database? I just need some generic way which checks that.
