  • Set AUTO_INCREMENT value programmatically

    - by Tim
    So this works... ALTER TABLE variation AUTO_INCREMENT = 10; But I want to do this; ALTER TABLE variation AUTO_INCREMENT = (SELECT MAX(id)+1 FROM old_db.varaition); but that doesnt work, and neither does; SELECT MAX(id)+1 INTO @old_auto_inc FROM old_db.variation ALTER TABLE variation AUTO_INCREMENT = @old_auto_inc; So does anyone know how to do this? ( I'm trying to ensure that AUTO_INCREMENT keys dont collide between an old and a new site and need to do this automatically. So I can just run a script when the new db goes live )

  • Array values changing unexpectedly

    - by Lizard
    I am using cakephp 1.2 and I have an array that appears to have a value change even though that variable is not being manipulated. Below is the code to that is causing me trouble. PLEASE NOTE - UPDATE Changing the variable name makes no difference to the outcome, The values get changed somewhere between the two print_r calls, and I can't see why the $this-find would do this . echo "Start of findCountByString()"; print_r($myArr); $test = $this->find('count', array( 'conditions' => $conditions, 'joins' => array('LEFT JOIN `articles_entities` AS ArticleEntity ON `ArticleEntity`.`article_id` = `Article`.`id`'), 'group' => 'Article.id' )); echo "End of findCountByString()"; print_r($myArr); I am getting the following output: Start of findCountByString() Array ( [0] => 4bdb1d96-c680-4c2c-aae7-104c39d70629 [1] => 4bdb1d6a-9e38-479d-9ad4-105c39d70629 [2] => 4bdb1b55-35f0-4d22-ab38-104e39d70629 [3] => 4bdb25f4-34d4-46ea-bcb6-104f39d70629 ) End of findCountByString() Array ( [0] => 4bdb1d96-c680-4c2c-aae7-104c39d70629 [1] => 4bdb1d6a-9e38-479d-9ad4-105c39d70629 [2] => 4bdb1b55-35f0-4d22-ab38-104e39d70629 [3] => '4bdb25f4-34d4-46ea-bcb6-104f39d70629' # This is now in inverted commas ) The the value in my array have changed, and I don't know why? Any suggestions?

  • Convert tax like IRS function to SQL

    - by CrashRoX
    Trying to convert this tax-like IRS function http://stackoverflow.com/questions/1817920/calculating-revenue-share-at-different-tiers to SQL. The assumption is the table would be one column (price) and the tiers will be added dynamically. My first attempt has some case statements that didn't work out well. I have since scrapped it :) Thanks for the help!

Query 2: Find out total of sales of a particual salesman in all the regions. (if the first one is solved I think this will be easy. :-) )

  • adding count( ) column on each row

    - by Arsenal
    I'm not sure if this is even a good question or not. I have a complex query with lot's of unions that searches multiple tables for a certain keyword (user input). All tables in which there is searched are related to the table book. There is paging on the resultset using LIMIT, so there's always a maximum of 10 results that get withdrawn. I want an extra column in the resultset displaying the total amount of results found however. I do not want to do this using a seperate query. Is it possible to add a count() column to the resultset that counts every result found? the output would look like this: ID Title Author Count(...) 1 book_1 auth_1 23 2 book_2 auth_2 23 4 book_4 auth_.. 23 ... Thanks!

  • Combining IN and NOT IN in SQL as single result

    - by UltraVi01
    I apologize for the vague title. I am attempting to write a query that returns an alias column with matching values (resulting from an IN) as well as an alias column with values that do not match (using NOT IN). I want the result set to have: userId | matches | nonmatches. I currently have the following query which returns the matches as expected. I am having trouble getting the nonmatches in the result set -- that is, from a NOT IN statement SET @userId = 9; SELECT ug.user_id, COUNT(DISTINCT goal_id) as matches FROM user_goal ug WHERE ug.user_id!=@userId AND goal_id IN (SELECT iug.goal_id FROM user_goal iug WHERE user_id=@userId) GROUP BY user_id ORDER BY matches DESC LIMIT 4 So, the NOT IN would look something like this: goal_id NOT IN(SELECT uggg.goal_id FROM user_goal uggg WHERE user_id=@userId) AS nonmatches I am just not sure how to incorporate the NOT IN statement in my query so I get all the results

  • highlighting data values in a sql result set

    - by potatoe
    I can think of a number of ways to do this in PHP or even JavaScript, but I'm wondering if there's a SQL-based technique I'm overlooking. I have a database table, let's say 20 fields X 10 rows. I want to display the entire table on an web page, so I'd do something like SELCT * FROM data_table;, and then format the result set using HTML table tags. However, I'd also like to highlight values in the table based on whether they are the maximum or minimum value in their column. For example, I'd add bold tags around the max in each column. A resulting table might look something like this, with bold tags shown: id | field1 | field2 | field3 | ... 0 | 5 | 2 | <b>7</b> | ... 1 | 3 | <b>8</b> | 6 | ... 2 | <b>9</b> | 5 | 1 | ... ... I could do a separate SELECT with an ORDER BY for each field and then interpret the results, but that seems like a lot of extra DB access. My alternative right now is to just fetch the whole table, and then sort/search for the highlight values using PHP. Is there a better way?

  • SUM a pair of COUNTs from two tables based on a time variable

    - by Kevin O.
    Been searching for an answer to this for the better part of an hour without much luck. I have two regional tables laid out with the same column names and I can put out a result list for either table based on the following query (swap Table2 for Table1): SELECT Table1.YEAR, FORMAT(COUNT(Table1.id),0) AS Total FROM Table1 WHERE Table1.variable='Y' GROUP BY Table1.YEAR Ideally I'd like to get a result that gives me a total sum of the counts by year, so instead of: | REGION 1 | | REGION 2 | | YEAR | Total | | YEAR | Total | | 2010 | 5 | | 2010 | 1 | | 2009 | 2 | | 2009 | 3 | | | | | 2008 | 4 | I'd have: | MERGED | | YEAR | Total | | 2010 | 6 | | 2009 | 5 | | 2008 | 4 | I've tried a variety of JOINs and other ideas but I think I'm caught up on the SUM and COUNT issue. Any help would be appreciated, thanks!

  • Select past date from database x days from now

    - by Pr0no
    Consider the following table daterange _date trading_day ------------------------ 2011-08-01 1 2011-07-31 0 2011-07-30 0 2011-07-29 1 2011-07-28 1 2011-07-27 1 2011-07-26 1 2011-07-25 1 2011-07-24 0 2011-07-23 0 2011-07-22 1 2011-07-21 1 2011-07-20 1 2011-07-19 1 2011-07-18 1 2011-07-17 0 I'm in need of a query that returns a _date, x days before a given _date. When counting back, _days with trading_day = 0 should be ignored. A few examples: input | output -------------------------+------------ 1 day before 2011-07-19 | 2011-07-18 2 days before 2011-08-01 | 2011-07-28 (trading_day = 0 don't count) 3 days before 2011-07-29 | 2001-07-26 The first one is easy: SELECT _date FROM daterange WHERE trading_day = 0 AND _date < '2011-07-19' LIMIT 1 But I don't know how to query for the other examples. Do you?

  • Locking a detail view if a user is editing the item...

    - by BenTheDesigner
    Hi All I am developing a user manager which must control access to the detail view of editable items. At present, when a user clicks 'edit', the application queries the link table to check if a user is currently editing that page, if not, it allows access to the page and then inserts a record into the link table preventing another user from editing the same page at the same time. My question is what would the best way to handle the removal of records if say a user exists the browser without saving etc, therefore no action to remove the record. I have a couple of ideas but would like other input before I decide. BenTheDesigner

  • MySQLi - declaring variable after bind_param?

    - by Kerry
    This may be a completely dumb question, but I've seen a couple examples declaring the variables AFTER putting them in bind_param: http://devzone.zend.com/article/686 I've never seen this done before and all my programming knowledge says I should define them before hand. Is this a valid/preferred way?

  • Multisite Enabling a Table

    - by Joe Fitzgibbons
    I am creating a table (table A) that will have a number of columns(of course) and there will be another table (table B) that holds metadata associated to rows in table A. I am working with a multi site implementation that has one database for the whole shabang. Rows in table A could belong to any number of sites but must belong to at least one. The problem I have is I am not sure what the best practice is for defining what site each row in table A belongs to. I want performance and scalability. There is no finite number of sites going forward. Rows in table A could belong to any number of sites in the future. Right now there are only 3. My initial thoughts are to have a primary site ID in Table A and then metadata in table B will have rows defining additional sites as needed. Another thought is to have a column in Table A for each site and it is a boolean as to wether it belongs to that site. Lastly I have thought about having another table to map rows in Table A to each site. What is the best way to associate rows in a table with any number of sites with performance and scalability in mind?

  • Best way to update record X when Y is inserted

    - by Saif Bechan
    I have a huge table that is mainly used for backup and administrative purposes. The only records that matters is the last inserted record. On every hit to order by time inserted is just too slow. I want keep a separate table with the last inserted id. In PHP I now insert, get last inserted id, and update the other table. Is there a more efficient way to do this.

  • Yii 'limit' on related model's scope

    - by pethee
    I have a model called Guesses that has_many Comments. I'm making eager queries to this to then pass on as JSON as response to an API call. The relations are obviously set between the two models and they are correct(one2many <= belongs2) I added a scope to Comments called 'api' like this: public function scopes() { return array( 'api' => array( 'select' => 'id, comment, date', 'limit'=>3, 'order'=>'date DESC', 'together'=>true, ), ); } And I'm running the following one-liner query: $data = Guesses::model()->with('comments:api')->findAll(); The issue here is that when calling the 'api' scope using a with('relation'), the limit property simply doesn't apply. I added the 'together'=true there for another type of scope, plus I hear it might help. It doesn't make a difference. I don't need all the comments of all Guesses. I want the top 3 (or 5). I am also trying to keep the one-liner call intact and simple, manage everything through scopes, relations and parameterized functions so that the API call itself is clean and simple. Any advice?

  • Very weird jquery/json problem...

    - by Scarface
    Hey guys I have finally located the cause of this problem...I just have no idea how to fix it and why it is happening. I have a jquery getjson function and it returns 0 results every 2-5 clicks on new topics or refreshes. For some reason if I change my query to sort results by ASC it always returns results and much quicker, but this poses a problem since I need results by DESC. If anyone has any ideas, I would greatly appreciate it because I am dumbfounded at this point. Here is my query but I need it by DESC SELECT time, user, message FROM comments WHERE topic_id='$topic_id' ORDER BY time ASC LIMIT 10 $.getJSON(files+"comments.php?action=view&load=initial&topic_id="+topic_id+"&t=" + (new Date()), function(json) { if(json.length) { for(i=0; i < json.length; i++) { $('#comment-list').prepend(prepare(json[i])); $('#list-' + count).fadeIn(1500); } } }); I return results like so while($row = mysql_fetch_array($res)){ $data[] = $row; } $out = json_encode($data); print $out;
