  I have one database Library with table named called Medien. Having multiple columns named as Fname,Mname,Lname and ISBN. I want to calculate database records with ISBN and without ISBN? I have execute following command Select COUNT(ISBN) as Verf1 FROM library.MEDIEN where verf1 = isbn; Select COUNT(ISBN) as Verf2 FROM library.MEDIEN where verf2 = isbn; Select COUNT(ISBN) as Verf3 FROM library.MEDIEN where verf3 = isbn; Select COUNT(ISBN) as Ntverf1 FROM library.MEDIENwhere verf1 != isbn; Select COUNT(ISBN) as Ntverf2 FROM library.MEDIENwhere verf2 != isbn; Select COUNT(ISBN) as Ntverf3 FROM library.MEDIENwhere verf3 != isbn; I am not sure i execute correct command or not.

• MOSS Faceted Search 3.0

  - by nav

  Hi, Has anyone installed Faceted Search v3.0 for MOSS working with date columns? When I map a column of DateTime type and click the Search BreadCrumb webpart "remove filter" link (next to the edit filter link) an exception is thrown. The search Breadcrumb webpart throws an error when I click the "Remove filter" link (this is the one represented by the broken link icon - next to the "Edit facet" icon). This seems to only occur after clicking the "Remove filter" link for Facets of DateTime type after which it occurs on every instance for all Facets. The error thrown is posted here: http://facetedsearch.codeplex.com/Thread/View.aspx?ThreadId=213398 Many Thanks, Nav

• sql server 2005 reporting services-- how to use multiple datasets in report

  - by larryq

  Hi everyone, I'm new to SQL Server reporting services, and am trying to decipher an existing report. It's nothing too bad, but I notice it does have two report datasets defined. (They are generated via separate stored procedures) I'm trying to figure out where and how the report datasets are linked together so the Fields collection has both sets of columns available and the report has a single rowset to traverse. Is there a section in the report layout where a joining of datasets is defined? I'm using Visual Studio 2005 to design and preview the report fwiw. Thanks for your help!

• How to combine two sql queries?

  - by plasmuska

  Hi Guys, I have a stock table and I would like to create a report that will show how often were items ordered. "stock" table: item_id | pcs | operation apples | 100 | order oranges | 50 | order apples | -100 | delivery pears | 100 | order oranges | -40 | delivery apples | 50 | order apples | 50 | delivery Basically I need to join these two queries together. A query which prints stock balances: SELECT stock.item_id, Sum(stock.pcs) AS stock_balance FROM stock GROUP BY stock.item_id; A query which prints sales statistics SELECT stock.item_id, Sum(stock.pcs) AS pcs_ordered, Count(stock.item_id) AS number_of_orders FROM stock GROUP BY stock.item_id, stock.operation HAVING stock.operation="order"; I think that some sort of JOIN would do the job but I have no idea how to glue queries together. Desired output: item_id | stock_balance | pcs_ordered | number_of_orders apples | 0 | 150 | 2 oranges | 10 | 50 | 1 pears | 100 | 100 | 1 This is just example. Maybe, I will need to add more conditions because there is more columns. Is there a universal technique of combining multiple queries together?

• Gtk# TreeView set a single cell to have a different renderer?

  - by Buttink

  OK this is probably insane, but I want to be able to have a check box at the very top of every row in my tree view. This box will "disable" or "enable" the ability to use the column. Oh I think it should be mentioned that I'm using a ListStore and am using C#, mono, GTK#. However, ill take anything and try to figure it out. Ill even accept a way to make two views where the columns line up .... So, possible? or just insane?

  I've got an ASP.net file, and I'm trying to include dynamic code which was easy in classic ASP.

• jquery js how to avoid massive onmouseover onmouseout firing

  - by stephan

  i have a table with some columns. in each of them is a picture where i have a onmouseover onmouseout event on it, which show a message in a div and hide the msg. my problem is - after a user goes quick from left to right (and moving) over a lot o images. all mouseover/out events of the images where executed, which looks stupid... is it possible to rearrange the internal event stack to avoid this? so that he executes only the current (mostly the first event) - and than the last one, if it is not same type eg. if mouseover over first image is executed and mouse moving position stops over an image 3times next the first one. i can avoid all other events firing, because the mouse stopped over an image and the mouseover is like the one where i stopped with the mouse. how can i avoid this multiple event firing?!

• SL3 TreeView Not Programmatically Scrolling

  - by Chris

  I have a treeview in Silverlight 3. The treeview is bound to a observable collection - which contains a list of hierarchical data. When the page loads initially, all nodes, by default, in the treeview, are collapsed. I have functionality that allows a certain item in the treeview to be selected programmatically. The problem that I am running into is when an item is selected that isn't immediately visible (i.e. one or more parent nodes are collapsed). I programmatically expand them, but, when I try to programmatically scroll into view, so the user can see the selected item, it doesn't work. I looked into this further, and I believe that it has to do with the calculated viewport height for the scroll viewer. It almost seems like a timing issue, as, if the item's parent node is expanded, and then the item is programmatically selected, the code that scrolls the treeview into view for that selected treeview item works perfectly. Please refer to the extension method below that I am using to scroll the treeview into view. Any help or suggestions on how to correct this would be greatly appreciated. Thanks. public static void BringIntoViewForScrollViewer(this FrameworkElement frameworkElement, ScrollViewer scrollViewer) { var transform = frameworkElement.TransformToVisual(scrollViewer); var positionInScrollViewer = transform.Transform(new Point(0, 0)); if (positionInScrollViewer.Y < 0 || positionInScrollViewer.Y > scrollViewer.ViewportHeight) scrollViewer.ScrollToVerticalOffset(scrollViewer.VerticalOffset + positionInScrollViewer.Y - ScrollPadding); }

• mysql query: SELECT DISTINCT column1, GROUP BY column2

  - by Adam

  Right now I have the following query: SELECT name, COUNT(name), time, price, ip, SUM(price) FROM tablename WHERE time >= $yesterday AND time <$today GROUP BY name And what I'd like to do is add a DISTINCT by column 'ip', i.e. SELECT DISTINCT ip FROM tablename So my final output would be all the columns, from all the rows that where time is today, grouped by name (with name count for each repeating name) and no duplicate ip addresses. What should my query look like? (or alternatively, how can I add the missing filter to the output with php)? Thanks in advance.

• .NET DataGridView rows' default alignment all set to left

  - by Xster

  DataGridView gets bound to DataTable. I then try to set some columns' DefaultCellStyle.Alignment to right. It doesn't work. After a bunch of tinkering, it turns out that every single row's DefaultCellStyle.Alignment is set to left and overrides it. DataGridView.DefaultCellStyle or RowsDefaultCellStyle doesn't do anything. Makes sense since a particular row's DefaultCellStyle is more specific but what gives. Why are they all set to something and not NotSet? How do I get rid of it instead of iterating through all rows?

• Odd GROUP BY output DB2 - Results not as expected

  - by CallCthulhu

  If I run the following query: select load_cyc_num , crnt_dnlq_age_cde , sum(cc_min_pymt_amt) as min_pymt , sum(ec_tot_bal) as budget , case when ec_tot_bal 0 then 'Y' else 'N' end as budget , case when ac_stat_cde in ('A0P','A1P','ARP','A3P') then 'Y' else 'N' end as arngmnt , sum(sn_close_bal) as st_bal from statements where (sn_close_bal 0 or ec_tot_bal 0) and load_cyc_num in (200911) group by load_cyc_num , crnt_dnlq_age_cde , case when ec_tot_bal 0 then 'Y' else 'N' end , case when ac_stat_cde in ('A0P','A1P','ARP','A3P') then 'Y' else 'N' end then I get the correct "BUDGET" grouping, but not the correct "ARRANGEMENT" grouping, only two rows have a "Y". If I change the order of the case statements in the GROUP BY, then I get the correct grouping (full Y-N breakdown for both columns). Am I missing something obvious?

• MySQL: updating a row and deleting the original in case it becomes a duplicate

  - by Silvio Donnini

  I have a simple table made up of two columns: col_A and col_B. The primary key is defined over both. I need to update some rows and assign to col_A values that may generate duplicates, for example: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 This statement sometimes yields a duplicate key error. I don't want to simply ignore the error with UPDATE IGNORE, because then the rows that generate the error would remain unchanged. Instead, I want them to be deleted when they would conflict with another row after they have been updated I'd like to write something like: UPDATE `table` SET `col_A` = 66 WHERE `col_B` = 70 ON DUPLICATE KEY REPLACE which unfortunately isn't legal in SQL, so I need help finding another way around. Also, I'm using PHP and could consider a hybrid solution (i.e. part query part php code), but keep in mind that I have to perform this updating operation many millions of times. thanks for your attention, Silvio Reminder: UPDATE's syntax has problems with joins with the same table that is being updated

I tried moving CompanyName in CrossTab columns and moved EmpId in rows & tried a cross tab group but results are not as expected. My questions are 1) Is this format achievable with a cross tab ? 2) How do I group record's by EmpId's in my crosstab in such a way that the Companies are moved horizontally ?

• How can I add an Items-like property to my User Control?

  - by Dan Tao

  It's pretty straightforward to add simple properties to a User Control that will appear in the desired categories in the Windows Forms designer, e.g.: [Category("Appearance")] public Color BackColor { get { return _textBox.BackColor; } set { _textBox.BackColor = value; } } What if I want to expose a more complex property, such as a collection of items of a type I define? I'm thinking something along the lines of the ListView.Items property, or the DataGridView.Columns property -- where the user of the control can access this complex property via a more specialized pop-up form (as opposed to a simple TextBox or ComboBox). Even a simple nudge in the right direction would be much appreciated.

• Clustered index dilemma - ID or sort?

  - by richardtallent

  I have a table with two very important fields: id INT identity(1,1) PRIMARY KEY identifiersortcode VARCHAR(900) My app always sorts and pages search results in the UI based on identifiersortcode, but all table joins (and they are legion) are on the id field. (Aside: yes, the sort code really is that long. There's a strong BL reason.) Also, due to O/RM use, most SELECT statements are going to pull almost every column. Currently, the clustered index is on id, but I'm wondering if the TOP / ORDER BY portion of most queries would make identifiersortcode a more attractive option as the clustered key, even considering all of the table joins going on. Inserts on the table and changes to the identifiersortcode are limited enough that changing my clustered index would be a problem for insert/update operations. Trying to make the sort code's non-clustered index a covering index (using INCLUDE) is not a good option. There are a number of large columns, and some of them have a lot of update activity.

• How can I set the line style of a specific cell in a QTableView?

  - by Bob Nelson

  I am working with a QT GUI. I am implementing a simple hex edit control using a QTableView. My initial idea is to use a table with seventeen columns. Each row of the table will have 16 hex bytes and then an ASCII representation of that data in the seventeenth column. Ideally, I would like to edit/set the style of the seventeenth column to have no lines on the top and bottom of each cell to give the text a free flowing appearance. What is the best way to approach this using the QTableView?

• Entity Framework 4: Inheritance and Optimistic Concurrency

  - by Mohammadreza

  Hi guys, I'm using AdventureWorks 2008 R2 database and added the BusinessEntity and Person tables to my EDMX. Then I changed the model in which the Person table inherits from the BusinessEntity table. As you may know these two tables have ModifiedDate and rowguid columns so the Person class should not have these properties because it inherits them from the BusinessEntity class. My question is, how can I modify the model to support inheritance and optimistic concurrency on both Person and BusinessEntity classes/tables on ModifiedDate property/column. PS. It also get me an error message that I have asked here. Thanks

• Why can I not view foreign language characters in my mysql DB?

  - by Chris

  I am inserting the following characters into my DB: ?? / ?? This is the meta tag on the page that is inserting the characters: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> I have altered all the columns in my table that is holding the characters to be utf8_unicode_ci The foreign characters show up like so in the DB: 汉字 / 漢字 When I use a sql statement to display those foreign characters on a page, they display correctly again as: ?? / ?? I am guessing I have some setting that is not correct in my DB, since it stores it correctly, but does not display it correctly. What can i do to make the foreign language characters to display correctly in my DB?

• system out output for double numbers in a java program

  - by Nikunj Chauhan

  I have a program where I am generating two double numbers by adding several input prices from a file based on a condition. String str; double one = 0.00; double two = 0.00; BufferedReader in = new BufferedReader(new FileReader(myFile)); while((str = in.readLine()) != null){ if(str.charAt(21) == '1'){ one += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51)); } else{ two += Double.parseDouble(str.substring(38, 49) + "." + str.substring(49, 51)); } } in.close(); System.out.println("One: " + one); System.out.println("Two: " + two); The output is like: One: 2773554.02 Two: 6.302505836000001E7 Question: None of the input have more then two decimals in them. The way one and two are getting calculated exactly same. Then why the output format is like this. What I am expecting is: One: 2773554.02 Two: 63025058.36 Why the printing is in two different formats ? I want to write the outputs again to a file and thus there must be only two digits after decimal.

• How to efficiently show many Images? (iPhone programming)

  - by Thomas

  In my application I needed something like a particle system so I did the following: While the application initializes I load a UIImage laserImage = [UIImage imageNamed:@"laser.png"]; UIImage *laserImage is declared in the Interface of my Controller. Now every time I need a new particle this code makes one: // add new Laserimage UIImageView *newLaser = [[UIImageView alloc] initWithImage:laserImage]; [newLaser setTag:[model.lasers count]-9]; [newLaser setBounds:CGRectMake(0, 0, 17, 1)]; [newLaser setOpaque:YES]; [self.view addSubview:newLaser]; [newLaser release]; Please notice that the images are only 17px * 1px small and model.lasers is a internal array to do all the calculating seperated from graphical output. So in my main drawing loop I set all the UIImageView's positions to the calculated positions in my model.lasers array: for (int i = 0; i < [model.lasers count]; i++) { [[self.view viewWithTag:i+10] setCenter:[[model.lasers objectAtIndex:i] pos]]; } I incremented the tags by 10 because the default is 0 and I don't want to move all the views with the default tag. So the animation looks fine with about 10 - 20 images but really gets slow when working with about 60 images. So my question is: Is there any way to optimize this without starting over in OpenGl ES? Thank you very much and sorry for my english! Greetings from Germany, Thomas

• MSSQL Search Proper Names Full Text Index vs LIKE + SOUNDEX

  - by Matthew Talbert

  I have a database of names of people that has (currently) 35 million rows. I need to know what is the best method for quickly searching these names. The current system (not designed by me), simply has the first and last name columns indexed and uses "LIKE" queries with the additional option of using SOUNDEX (though I'm not sure this is actually used much). Performance has always been a problem with this system, and so currently the searches are limited to 200 results (which still takes too long to run). So, I have a few questions: Does full text index work well for proper names? If so, what is the best way to query proper names? (CONTAINS, FREETEXT, etc) Is there some other system (like Lucene.net) that would be better? Just for reference, I'm using Fluent NHibernate for data access, so methods that work will with that will be preferred. I'm using MS SQL 2008 currently.
