  • Select count() max() Date

    - by DAVID
    I have a table with shifts history along with emp ids. I'm using this query to retrieve a list of employees and their total shifts by specifying the range to count from: SELECT ope_id, count(ope_id) FROM operator_shift WHERE ope_shift_date >=to_date( '01-MAR-10','dd-mon-yy') and ope_shift_date <= to_date('31-MAR-10','dd-mon-yy') GROUP BY OPE_ID which gives OPE_ID COUNT(OPE_ID) 1 14 2 7 3 6 4 6 5 2 6 5 7 2 8 1 9 2 10 4 10 rows selected. How do I choose the employee with the highest number of shifts under the specified range date?

  • Running log operation in Http Modules?

    - by Niranjan
    Hi, I have a simple requirement in which I want to execute a long running application program on server (e.g. DTSX) I want to make an HTTP module for this, But I have a question whether the DTSX will run even if the user closes the page and browser. In my case user hits the handler with a query string but what if the user closes the browser immediately? How is the behavior different from simple linear page processing? I want my DTSX package to finish once its started no matter how much time it takes and also dont want to halt the user that is why I am using http modules in place of linear asp page processing. Reagrds, Niranjan

  • Correct usage of Voldemort as key-value pair?

    - by zengr
    Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.

  • WordPress get_post_count?

    - by Scott B
    I'd like to create a function that retrieves the post count for a given query. I don't want to use get_posts obviously as its way to expensive for this purpose. However, that's exactly what I'm having to use in absense of a get_post_count function. My code is... global $post; $cat=get_cat_ID('mymenu'); $catHidden=get_cat_ID('hidden'); $myrecentposts = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => $NumberOfPostsToShow)); $myrecentposts2 = get_posts(array('post_not_in' => get_option('sticky_posts'), 'cat' => "-$cat,-$catHidden",'showposts' => -1)); $myrecentpostscount = count($myrecentposts2);

  • Classic ASP result set - ultimate confusion!

    - by Paul
    Consider a simple result set from a mysql query. rs("description") and rs("description").Value should be considered as the same thing. However, depending on how you access them, you get different results (!!) Access rs("description") directly and you are returned a "Field" object. Or, more importantly, use it directly in a call, and you are returned a "Field" object. mydescription = rs("description") + " is the description" Assign it to another variable, and the Value of that object is assigned... mydescription = rs("description") the contents of "mydescription" is a string. Why this difference? At one point in the life of ASP they must have both worked exactly the same, so why have they changed, and how can I change it back?

  • SQL Like question

    - by mike
    Is there a way to reverse the SQL Like operator so it searches a field backwards? For example, I have a value in a field that looks like this "Xbox 360 Video Game". If I write a query like below, it returns the result fine. SELECT id FROM table WHERE title like "%Xbox%Game%" However, when I search like this, it doesn't find any results. SELECT id FROM table WHERE title like "%Video%Xbox%" I need it to match in any direction. How can I get around this?

  • How are SaaS applications organized?

    - by tomekw
    Consider web (MVC, for example Rails) application for multiple clients as a service. How to design this? one application instance per client? (+ one database per client) one instance for all clients (+ one database for all clients) Former one is simple, but... "inefficient". How about the latter? (best practises, design patterns) How to separate client data? For example: worker "A" of client "1" has two documents, worker "B" of client "2" has three documents. How to build model associations to protect other users (and clients) data? I think joining every query with Client model is not a good solution.

  • Correct sequence of actions when using Markdown & MySQL?

    - by Andrew Heath
    I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

  • Converting delimited string to multiple values in mysql

    - by epo
    I have a mysql legacy table which contains an client identifier and a list of items, the latter as a comma-delimited string. E.g. "xyz001", "foo,bar,baz". This is legacy stuff and the user insists on being able to edit a comma delimited string. They now have a requirement for a report table with the above broken into separate rows, e.g. "xyz001", "foo" "xyz001", "bar" "xyz001", "baz" Breaking the string into substrings is easily doable and I have written a procedure to do this by creating a separate table, but that requires triggers to deal with deletes, updates and inserts. This query is required rarely (say once a month) but has to be absolutely up to date when it is run, so e.g. the overhead of triggers is not warranted and scheduled tasks to create the table might not be timely enough. Is there any way to write a function to return a table or a set so that I can join the identifier with the individual items on demand?

  • Parametrize the WHERE clause?

    - by ControlFlow
    Hi, stackoverflow! I'm need to write an stored procedure for SQL Server 2008 for performing some huge select query and I need filter it results with specifying filtering type via procedure's parameters (parameterize where clause). I found some solutions like this: create table Foo( id bigint, code char, name nvarchar(max)) go insert into Foo values (1,'a','aaa'), (2,'b','bbb'), (3,'c','ccc') go create procedure Bar @FilterType nvarchar(max), @FilterValue nvarchar(max) as begin select * from Foo as f where case @FilterType when 'by_id' then f.id when 'by_code' then f.code when 'by_name' then f.name end = case @FilterType when 'by_id' then cast(@FilterValue as bigint) when 'by_code' then cast(@FilterValue as char) when 'by_name' then @FilterValue end end go exec Bar 'by_id', '1'; exec Bar 'by_code', 'b'; exec Bar 'by_name', 'ccc'; But it doesn't work when the columns has different data types... It's possible to cast all the columns to nvarchar(max) and compare they as strings, but I think it will cause a performance degradation... Is it possible to parameterize where clause in stored procedure without using things like EXEC sp_executesql (dynamic SQL and etc.)?

  • Iterator blocks in Clojure?

    - by Checkers
    I am using clojure.contrib.sql to fetch some records from an SQLite database. (defn read-all-foo [] (with-connection *db* (with-query-results res ["select * from foo"] (into [] res)))) Now, I don't really want to realize the whole sequence before returning from the function (i.e. I want to keep it lazy), but if I return res directly or wrap it some kind of lazy wrapper (for example I want to make a certain map transformation on result sequence), SQL-related bindings will be reset and connection will be closed after I return, so realizing the sequence will throw an exception. How can I enclose the whole function in a closure and return a kind of iterator block (like yield in C# or Python)? Or is there another way to return a lazy sequence from this function?

  • How to select difference using sql?

    - by ganuke
    I wrote a sql query to retrieve data as follows: SELECT (MAX (b.filledqty) - MAX (a.filledqty)) AS filledtoday FROM clientordermas a, clientordermas b WHERE a.clordid = 'w9110126' AND b.clordid = 'w9110126' AND (SELECT max(a.price) FROM clientordermas a WHERE a.clordid = 'w9110126') < 1000; There are three records in the table for the given clordid with price values 800, 900 1200. So, what I need is to get the difference between 1200 and 900 which is 300. But, the above statement always returns 0. What I should get is MAX (b.filledqty) retuns 1200 and MAX (a.filledqty) retuns 900. But it is not happening. This is not the exact problem I am facing but a simplified version of it. Can someone please help?

  • How to calculate real-time stats?

    - by Diego Jancic
    I have a site with millions of users (well, actually it doesn't have any yet, but let's imagine), and I want to calculate some stats like "log-ins in the past hour". The problem is similar to the one described here: http://highscalability.com/blog/2008/4/19/how-to-build-a-real-time-analytics-system.html The simplest approach would be to do a select like this: select count(distinct user_id) from logs where date>='20120601 1200' and date <='20120601 1300' (of course other conditions could apply for the stats, like log-ins per country) Of course this would be really slow, mainly if it has millions (or even thousands) of rows, and I want to query this every time a page is displayed. How would you summarize the data? What should go to the (mem)cache? EDIT: I'm looking for a way to de-normalize the data, or to keep the cache up-to-date. For example I could increment an in-memory variable every time someone logs in, but that would help to know the total amount of logins, not the "logins in the last hour". Hope it's more clear now.

  • What is a typical scenario for and end-user reports design?

    - by Sebastian
    Hello! I'm wondering what would be the typical scenario for using an end-user report designer. What I'm thinking of is to have a base report with all the columns that I can have, also with a basic view of the report (formatting, order of columns, etc.) and then let the user to change that format and order, take out or add (from the available columns) data to it, etc. Is that a common way to address what is called end-user designer for reports or I'm off track? I know it depends on the user (if it's someone that can handle SQL or not for example), but is it common to have a scenario where the user can build everthing from the sql query to the formatting? Thanks! Sebastian

  • Using ManagementObject to retrieve a single WMI property

    - by Jesse
    This probably isn't the best way, but I am currently retrieving the amount of RAM on a machine using: manageObjSearch.Query = new ObjectQuery("SELECT TotalVisibleMemorySize FROM Win32_OperatingSystem"); manageObjCol = manageObjSearch.Get(); foreach (ManagementObject mo in manageObjCol) sizeInKilobytes = Convert.ToInt64(mo["TotalVisibleMemorySize"]); It works well and good, but I feel I could be doing this more directly and without a foreach over a single element, but I can't figure out how to index a ManagementObjectCollection I want to do something like this: ManagementObject mo = new ManagementObject("Win32_OperatingSystem.TotalVisibleMemorySize") mo.Get(); Console.WriteLine(mo["TotalVisibleMemorySize"].ToString()) or maybe even something like ManagementClass mc = new ManagementClass("Win32_OperatingSystem"); Console.WriteLine(mc.GetPropertyValue("TotalVisibleMemorySize").ToString()); I just can't seem to figure it out. Any ideas?

  • SQL Server join and wildcards

    - by Ernst
    I want to get the results of a left join between two tables, with both having a column of the same name, the column on which I join. The following query is seen as valid by the import/export wizard in SQL Server, but it always gives an error. I have some more conditions, so the size wouldn't be too much. We're using SQL Server 2000 iirc and since we're using an externally developed program to interact with the database (except for some information we can't retrieve that way), we can not simply change the column name. SELECT table1.*, table2.* FROM table1 LEFT JOIN table2 ON table1.samename = table2.samename At least, I think the column name is the problem, or am I doing something else wrong?

  • Rails: link_to with block and GET params?

    - by bobthabuilda
    How can I achieve query string and URL parameters in a link_to block declaration? Right now, I have this, which works: <%= link_to 'Edit', :edit, :type => 'book', :id => book %> The above works, and outputs: http://localhost:3000/books/edit/1?type=book What I want to do is something like this: <% link_to :edit, :type => 'book', :id => book do %> ... <% end %> But the above format outputs: http://localhost:3000/books/edit/ Which isn't what I'm looking for... I want it to output a URL like the previous example. How can I achieve this?

  • How to schedule emails to send out

    - by luckytaxi
    Using PHP, I have a query that goes through my DB looking for pending tasks with reminder triggers at certain times of the day. I have a cronjob that runs every 10 mins and checks the DB for any rows that has "remind_me" field set to go off within the next 10 mins. If it does find something, what's the best way to queue an email with the task information? I guess I'll need some sort of message queue system, but how does the email part work? Will I need another cronjob that runs every minute to check the queue system?
