• How to order the images in a mysql database?

  - by user305270

  Hy! Here is my problem: i have a profile and this profile has for example 100 images. When someone visit this profile the first image will be the first result of my query that sorts by updated_at. But if the user would want to put the image with the (id = 8) to be the first, then (id = 22) then (id = 88) and so on? I need to put another field or is really necessary a new table to make a custom sort on images? and maybe someone explain this to me how to do? thanks, i appreciate your help ;)

• Variable height UIViews and labels

  - by Bob Spryn

  Ok so I'm not in a table cell at this point. (I've seen a lot of threads regarding the height of cells.) I have a detail view with a title and description at the top of the view, followed by a tableView below it. If the description is going to vary in length, how do I get the tableView to adjust with it accordingly so it always starts directly below it? I see apple doing this in the app store application. If you look at an application description (as if you were going to buy it), they have an application description, and wherever that ends a scrolling pane of screenshots follow. How do they do the varying height on the text description like that? Are they doing this all programmatically or can I use the layout controls in IB to do the same thing?

• Linq to NHibernate using Queryable.Where predicate

  - by Groo

  I am querying an SQLite database using LINQ to NHibernate. Person is an entity containing an Id and a Name: public class Person { public Guid Id { get; private set; } public string Name { get; private set; } } Let's say my db table contains a single person whose name is "John". This test works as expected: var query = from item in session.Linq<Person>() where (item.Name == "Mike") select item; // no such entity should exist Assert.IsFalse(query.Any()); but this one fails: var query = from item in session.Linq<Person>() select item; query.Where(item => item.Name == "Mike"); // following line actually returns the // "John" entry Assert.IsFalse(query.Any()); What am I missing?

• Core Data => Adding a related object always nil

  - by mongeta

  Hello, I have two tables related: DataEntered and Model DataEntered -currentModel Model One DataEntered can have only ONE Model, but a Model can stay into many DataEntered. The relationship is from DataEntered to Model (No To Many-relathionship) and no inverse relation. XCode generates the setters for DataEnteredModel: @property (nonatomic, retain) NSSet * current_model; - (void)addCurrent_modelObject:(CarModel *)value; - (void)addCurrent_model:(NSSet *)value; I have a Table and when I select a model, I want to store it to DataEntered: Model *model = [fetchedResultsController objectAtIndexPath:indexPath]; NSLog(@"Model %@",model.name); // ==> gives me the correct model name [dataEntered addCurrent_modelObject:model]; // ==> always nil [dataEntered setCurrent_model:[fetchedResultsController objectAtIndexPath:indexPath]]; // the same, always nil what I'm doing wrong ????? thanks, r.

• How do I filter one of the columns in a SQL Server SQL Query

  - by Kent S. Clarkson

  I have a table (that relates to a number of other tables) where I would like to filter ONE of the columns (RequesterID) - that column will be a combobox where only people that are not sales people should be selectable. Here is the "unfiltered" query, lets call it QUERY 1: SELECT RequestsID, RequesterID, ProductsID FROM dbo.Requests If using a separate query, lets call it QUERY 2, to filter RequesterID (which is a People related column, connected to People.PeopleID), it would look like this: SELECT People.PeopleID FROM People INNER JOIN Roles ON People.RolesID = Roles.RolesID INNER JOIN Requests ON People.PeopleID = Requests.RequesterID WHERE (Roles.Role <> N'SalesGuy') ORDER BY Requests.RequestsID Now, is there a way of "merging" the QUERY 2 into QUERY 1? (dbo.Requests in QUERY 1 has RequesterID populated as a Foreign Key from dbo.People, so no problem there... The connections are all right, just not know how to write the SQL query!)

• SQL 2005: Select top N, group by ID with joins

  - by Suzy Fresh

  I'm having real difficulty with a query involving 3 tables. I need to get the 3 newest users per department grouped by department names. The groups should be sorted by the users.dateadded so the department with the newest activity is first. The users can exist in multiple departments so Im using a lookup table that just contains the userID and deptID. My tables are as follows. Department - depID|name Users - userID|name|dateadded DepUsers - depID|userID The output I need would be Receiving John Doe - 4/23/2010 Bill Smith - 4/22/2010 Accounting Steve Jones - 4/22/2010 John Doe - 4/21/2010 Auditing Steve Jones - 4/21/2010 Bill Smith - 4/21/2010

• Paypal subscribe now button

  - by Bharadwaj

  Hi, I have built an information portal in PHP [Something like a recipe book], where the first few recipes are free to access. The advanced recipes are available only to paid members. I intend to use a simple subscribe now paypal button. When the user clicks on this button, he is directed to paypal website and upon payment redirected to my site. How do I collect the payment information from paypal? I do not want to use a wsdl. I need the information to update my user level field [0 for registered users, 1 for paid users] in the users table. Any pointers? Does IPN do the trick for this? Is there a better solution for this? Thanks, Bharadwaj

• How do I do a where clause in sql and return a count back?

  - by chobo2

  Hi I am using mssql and I want to make a query that returns a count back with a where clause. Like say I have a product Table ProductId ProductName Active So how would I make it I have like Select Count(*) From Product now I don't know how to filter it so it only could if Active = true; So if there are 3 active products then it would return a count of 3 even if there is a hundred rows in the db and the other 97 are only not active. so the where clause would be probably like where active = true I am not sure how to put them together though.

• MySQL: Count two things in one query?

  - by Nebs

  I have a "boolean" column in one of my tables (value is either 0 or 1). I need to get two counts: The number of rows that have the boolean set to 0 and the number of rows that have it set to 1. Currently I have two queries: One to count the 1's and the other to count the 0's. Is MySQL traversing the entire table when counting rows with a WHERE condition? I'm wondering if there's a single query that would allow two counters based on different conditions? Or is there a way to get the total count along side the WHERE conditioned count? This would be enough as I'd only have to subtract one count from the other (due to the boolean nature of the column). There are no NULL values. Thanks.

• PostgreSQL String search for partial patterns removing exrtaneous characters

  - by tbrandao

  Looking for a simple SQL (PostgreSQL) regular expression or similar solution (maybe soundex) that will allow a flexible search. So that dashes, spaces and such are omitted during the search. As part of the search and only the raw characters are searched in the table.: Currently using: SELECT * FROM Productions WHERE part_no ~* '%search_term%' If user types UTR-1 it fails to bring up UTR1 or UTR 1 stored in the database. But the matches do not happen when a part_no has a dash and the user omits this character (or vice versa) EXAMPLE search for part UTR-1 should find all matches below. UTR1 UTR --1 UTR 1 any suggestions...

• Case insensitive string compare in LINQ-to-SQL

  - by BlueMonkMN

  I've read that it's unwise to use ToUpper and ToLower to perform case-insensitive string comparisons, but I see no alternative when it comes to LINQ-to-SQL. The ignoreCase and CompareOptions arguments of String.Compare are ignored by LINQ-to-SQL (if you're using a case-sensitive database, you get a case-sensitive comparison even if you ask for a case-insensitive comparison). Is ToLower or ToUpper the best option here? Is one better than the other? I thought I read somewhere that ToUpper was better, but I don't know if that applies here. (I'm doing a lot of code reviews and everyone is using ToLower.) Dim s = From row In context.Table Where String.Compare(row.Name, "test", StringComparison.InvariantCultureIgnoreCase) = 0 This translates to an SQL query that simply compares row.Name with "test" and will not return "Test" and "TEST" on a case-sensitive database.

• Showing a loading spinner only if the data has not been cached.

  - by Aaron Mc Adam

  Hi guys, Currently, my code shows a loading spinner gif, returns the data and caches it. However, once the data has been cached, there is a flicker of the loading gif for a split second before the data gets loaded in. It's distracting and I'd like to get rid of it. I think I'm using the wrong method in the beforeSend function here: $.ajax({ type : "GET", cache : false, url : "book_data.php", data : { keywords : keywords, page : page }, beforeSend : function() { $('.jPag-pages li:not(.cached)').each(function (i) { $('#searchResults').html('<p id="loader">Loading...<img src="../assets/images/ajax-loader.gif" alt="Loading..." /></p>'); }); }, success : function(data) { $('.jPag-current').parent().addClass('cached'); $('#searchResults').replaceWith($(data).find('#searchResults')).find('table.sortable tbody tr:odd').addClass('odd'); detailPage(); selectForm(); } });

• Decimal data Type Display scale part as zero

  - by Wael Dalloul

  I have Decimal field in SQLserver 2005 table, Price decimal(18, 4) if I write 12 it will be converted to 12.0000, if I write 12.33 it will be converted into 12.3300. Always it's putting zero to the right of the decimal point in the count of Scale Part(4). I was using these in SQL Server 2000, it was not behaving like this, in SQL Server 2000 if I put 12.5 it will be stored as 12.5 not as 12.5000 what SQLServer2005 do. My Question is how to stop SQL Server 2005 from putting zeros to the right of the decimal point?

• How to escape <, >, and & characters to html entities in Oracle PL/SQL

  - by SWilk

  Hi, I need to send HTML emails directly from oracle PL/SQL package. This works almost fine. I have problem with the fact that some of the data fetched from a table contain things like <S>, <L>, and similar fragments, which sometimes ar treated as HTML tags, and even if not, they are always ignored and never displayed. So, I need to escape this column before inserting into email body. Is there a function to escape html special chars into entities automaticly? Or do I need to replace('<','&lt;',string) manually all the special characters? I found a function to escape URLs but not one for HTML :( Best regards, SWilk

• Fastest method for SQL Server inserts, updates, selects

  - by Ian

  I use SPs and this isn't an SP vs code-behind "Build your SQL command" question. I'm looking for a high-throughput method for a backend app that handles many small transactions. I use SQLDataReader for most of the returns since forward only works in most cases for me. I've seen it done many ways, and used most of them myself. Methods that define and accept the stored procedure parameters as parameters themselves and build using cmd.Parameters.Add (with or without specifying the DB value type and/or length) Assembling your SP params and their values into an array or hashtable, then passing to a more abstract method that parses the collection and then runs cmd.Parameters.Add Classes that represent tables, initializing the class upon need, setting the public properties that represent the table fields, and calling methods like Save, Load, etc I'm sure there are others I've seen but can't think of at the moment as well. I'm open to all suggestions.

• Can a .csv file be used as a data source in Visual Studio 2008?

  - by Kevin

  I'm pretty new to C# and Visual Studio. I'm writing a small program that will read a .csv file and then write the records read to a SQL Server database table. I can manually parse the .csv file, but I was wondering if it is possible to somehow "describe" the .csv file to Visual Studio so that I can use it as a data source? I should mention that the first two lines in the .csv file contain header information and the following lines are the actual comma-delimited data. Also, I should mention that this program is a stand-alone console program with no user interface.

• What ways can I put images in a grid-like format?

  - by Peter

  I have about 12-15 images that I want to align together in a grid, with text under each image. I thought about using a table, but I hear that tables aren't the best way to go these days. I tried a few other things, but nothing seemed to work the way I wanted it to. An example of what I want it to look like would be something like this: [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 1 (--Description-) (-Description-) (-Description-) (-Description-) [-----Image-----] [-----Image-----] [-----Image-----] [-----Image-----] --- Row 2 (--Description-) (-Description-) (-Description-) (-Description-) and so on... What are some other methods, besides tables, that I should look into using? Any suggestions or references would be helpful.

There is OrderLine class which has a BaseProduct. My problem is when i select an OrderLine with related product i don't know how cast BaseProduct to derived product. for example i have this query: var order = (from odr in _context.Orders join orderLine in _context.OrderLines on odr.Id equals orderLine.OrderId join hotel in _context.Products.OfType<HotelProduct>() on orderLine.ProductId equals hotel.Id where odr.UserId == userId && odr.Id == orderId orderby odr.OrderDate descending select odr).SingleOrDefault(); In OrderLine i have BaseProduct properties not properties of HotelProduct. Is there any way to cast BaseProduct to derived class in OrderLine or any other solutions ?

• Copy Rows in a One to Many with LINQ (2 SQL)

  - by Refracted Paladin

  I have a table that stores a bunch of diagnosis for a single plan. When the users create a new plan I need to copy over all existing diagnosis's as well. I had thought to try the below but this is obviously not correct. I am guessing that I will need to loop through my oldDiagnosis part, but how? Thanks! My Attempt so far... public static void CopyPlanDiagnosis(int newPlanID, int oldPlanID) { using (var context = McpDataContext.Create()) { var oldDiagnosis = from planDiagnosi in context.tblPlanDiagnosis where planDiagnosi.PlanID == oldPlanID select planDiagnosi; var newDiagnosis = new tblPlanDiagnosi { PlanID = newPlanID, DiagnosisCueID = oldDiagnosis.DiagnosisCueID, DiagnosisOther = oldDiagnosis.DiagnosisOther, AdditionalInfo = oldDiagnosis.AdditionalInfo, rowguid = Guid.NewGuid() }; context.tblPlanDiagnosis.InsertOnSubmit(newDiagnosis); context.SubmitChanges(); } }

• How to commit inside a CURSOR Loop?

  - by user320587

  Hi, I am trying to see if its possible to perform Update within a cursor loop and this updated data gets reflected during the second iteration in the loop. DECLARE cur CURSOR FOR SELECT [Product], [Customer], [Date], [Event] FROM MyTable WHERE [Event] IS NULL OPEN cur FETCH NEXT INTO @Product, @Customer, @Date, @Event WHILE @@FETCH_STATUS = 0 BEGIN SELECT * FROM MyTable WHERE [Event] = 'No Event' AND [Date] < @DATE -- Now I update my Event value to 'No Event' for records whose date is less than @Date UPDATE MyTable SET [Event] = 'No Event' WHERE [Product] = @Product AND [Customer] = @Customer AND [Date] < @DATE FETCH NEXT INTO @Product, @Customer, @Date, @Event END CLOSE cur DEALLOCATE cur Assume when the sql executes the Event column is NULL for all records In the above sql, I am doing a select inside the cursor loop to query MyTable where Event value is 'No Event' but the query returns no value even though I am doing an update in the next line. So, I am thinking if it is even possible to update a table and the updated data get reflected in the next iteration of the cursor loop. Thanks for any help, Javid
