  • adhoc struct/class in C#?

    - by acidzombie24
    Currently i am using reflection with sql. I find if i want to make a specialize query it is easiest to get the results by creating a new class inheriting from another and adding the 2 members/columns for my specialized query. Then due to reflections in the lib in my c# code i can write foreach(var v in list) { v.AnyMember and v.MyExtraMember) Now instead of having the class scattered around or modifying my main DB.cs file can i define a class inside a function? I know i can create an anonymous object by writing new {name=val, name2=...}; but i need a to pass this class in a generic function func(query, args);

  • Using a table-alias in Kohana queries?

    - by Aristotle
    I'm trying to run a simple query with $this->db in Kohana, but am running into some syntax issues when I try to use an alias for a table within my query: $result = $this->db ->select("ci.chapter_id, ci.book_id, ci.chapter_heading, ci.chapter_number") ->from("chapter_info ci") ->where(array("ci.chapter_number" => $chapter, "ci.book_id" => $book)) ->get(); It seems to me that this should work just fine. I'm stating that "chapter_info" ought to be known as "ci," yet this isn't taking for some reason. The error is pretty straight-forward: There was an SQL error: Table 'gb_data.chapter_info ci' doesn't exist - SELECT `ci`.`chapter_id`, `ci`.`book_id`, `ci`.`chapter_heading`, `ci`.`chapter_number` FROM (`chapter_info ci`) WHERE `ci`.`chapter_number` = 1 AND `ci`.`book_id` = 1 If I use the full table name, rather than an alias, I get the expected results without error. This requires me to write much more verbose queries, which isn't ideal. Is there some way to use shorter names for tables within Kohana's query-builder?

  • Aggregate Functions on subsets of data based on current row values with SQL

    - by aasukisuki
    Hopefully that title makes sense... Let's say I have an employee table: ID | Name | Title | Salary ---------------------------- 1 | Bob | Manager | 15285 2 | Joe | Worker | 10250 3 | Al | Worker | 11050 4 | Paul | Manager | 16025 5 | John | Worker | 10450 What I'd like to do is write a query that will give me the above table, along with an averaged salary column, based on the employee title: ID | Name | Title | Salary | Pos Avg -------------------------------------- 1 | Bob | Manager | 15285 | 15655 2 | Joe | Worker | 10250 | 10583 3 | Al | Worker | 11050 | 10583 4 | Paul | Manager | 16025 | 15655 5 | John | Worker | 10450 | 10583 I've tried doing this with a sub-query along the lines of: Select *, (select Avg(e2.salary) from employee e2 where e2.title = e.title) from employee e But I've come to realize that the sub-query is executed first, and has no knowledge of the table alias'd e I'm sure I'm missing something REALLY obvious here, can anyone point me in the right diretion?

  • RewriteCond and Full QUERY_STRING

    - by Tim
    I'm having hard time getting my head wrapped around this one - and it should be trivial. I would like to redirect one URL with a specific query string to another URL. I want to send any requests that contain the query string in the URL http://mysite.com/index.php?option=com_user&view=register To: http://mysite.com/index.php?option=com_regme&view=form&regme=4&random=0&Itemid=6 If they add anything to the end of the first URL, it should still go to the second URL so that they cannot bypass the redirection. Nothing in the first query string needs to be preserved and passed to the second - all I want to do is change the URL completely. I'm tearing my hair out trying to get this to work yet it should be trivial. Suggestions? Thanks, -Tim

  • SQL syntax Newbie student

    - by sammysmall
    Describe the output of the following SQL query: select custId, name from customer where region = "New York" UNION select cust.custId, cust.name from customer cust where cust.custId IN (select cust_order.custId from customer_order cust_order, company_employee comp_emp where cust_order.salesEmpId = comp_emp.empId AND comp_emp.name = 'DANIEL'); My question is: at line from customer cust is cust referring to a column in the customer table... This is a homework question I have identified the components leading up to this line and I think that cust is a column in the customer table... I am not asking for an overall solution just a bit of encouragement if I am on the right track...

  • Reliable way to get the "ancestor" of an object with a specific classname, using jQuery

    - by Matt Dawdy
    I've got a javascript function that gets called on change event of a select form element. So, the "this" variable in js refers to the select element. This select element is in a td tag, in a tr tag. The tr tag has a classname of "FilterDetailsRow". Now, I've tested, and if I use this syntax: var filterRow = $(this).parent().parent(); it gets me what I want. However, is there a better way to tell jQuery, "starting with "this" can you please go up my tree of parents until you find one with a classname of "FilterDetailsRow"? Here's what I came up with, but I want to make sure I"m not reinventing the wheel. function GetFilterDetailsRowOfObject(o) { if (o) { if (o.parent()[0].className.indexOf("FilterDetailsRow") != -1) return o; else return GetFilterDetailsRowOfObject(o.parent()); } else { return null; } } Thanks for any advice.

  • How do I get the ID or reference of the listview row I am clicking a checkbox in?

    - by danielea
    I have an ASP.NET 2.0 ListView control (aka:parent) and configured inside this ListView I have another ListView (aka:child). For each row the parent has there is potentially a child ListView control which can have 1-3 rows. Each row has two checkboxes (a select checkbox and a deny checkbox). I need to process these checkboxes in JavaScript so that if one select is chosen on any of the rows all other select checkboxes are unchecked AND the deny checkbox for that row only is unchecked. The rows which were NOT selected CAN have the deny checkboxes checked. What is the best approach to this?

  • Why can i read dirty rows in MySql

    - by acidzombie24
    I cant believe this, i always throught the below would be concurrency safe. I write to a row in one transaction and i am able to read the dirty value from another transaction/command/connection! Why is this possible (not my main question) isnt this not desired and cause more troubles!?! Anyways, i expected that once i write to a row nothing else will be able to read to the row until the transaction is finished. And at least if the row can be still read that the clean (original) value will be read. (but maybe that would cause problems as well if the transaction doesnt use the newly commited data from the other transaction when it is ran) I would like count to == 11. I thought this would be safe in all variants of sql. What can i do to either 1) Not read the dirty value but clean 2) Have that row be locked until the transaction is finished? static MySqlConnection MakeConn() { string connStr = "server=192.168.126.128;user=root;database=TestDB;port=3306;password=a;"; MySqlConnection conn = new MySqlConnection(connStr); conn.Open(); return conn; } static Semaphore sem1 = new Semaphore(1, 1); static Semaphore sem2 = new Semaphore(1, 1); static void Main2() { Console.WriteLine("Starting Test"); // sem1.WaitOne(); Console.WriteLine("1W"); sem2.WaitOne(); Console.WriteLine("2W"); Thread oThread = new Thread(new ThreadStart(fn2)); oThread.Start(); var conn = MakeConn(); var cmd = new MySqlCommand(@" CREATE TABLE IF NOT EXISTS Persons ( P_Id int NOT NULL, name varchar(255), count int, PRIMARY KEY (P_Id) )", conn); cmd.ExecuteNonQuery(); cmd.CommandText = "delete from Persons; insert into Persons(name, count) VALUES('E', '4');"; cmd.ExecuteNonQuery(); cmd.CommandText = "select count from Persons;"; var count = (int)cmd.ExecuteScalar(); Console.WriteLine("Finish inserting. v={0}", count); sem2.Release(); Console.WriteLine("2R"); sem1.WaitOne(); Console.WriteLine("1W"); Console.WriteLine("Starting transaction"); using (var tns = conn.BeginTransaction()) { cmd.CommandText = "update Persons set count=count+1"; cmd.ExecuteNonQuery(); cmd.CommandText = "select count from Persons;"; count = (int)cmd.ExecuteScalar(); Console.WriteLine("count is {0}", count); sem2.Release(); Console.WriteLine("2R"); sem1.WaitOne(); Console.WriteLine("1W"); count += 5; //10 cmd.CommandText = "update Persons set count=" + count.ToString(); cmd.ExecuteNonQuery(); cmd.CommandText = "select count from Persons;"; count = (int)cmd.ExecuteScalar(); Console.WriteLine("count is {0}", count); tns.Commit(); } Console.WriteLine("finished transaction 1"); sem2.Release(); Console.WriteLine("2R"); sem1.WaitOne(); Console.WriteLine("1W"); cmd.CommandText = "select count from Persons;"; count = (int)cmd.ExecuteScalar(); Console.WriteLine("count is {0}", count); sem2.Release(); Console.WriteLine("2R"); //sem1.WaitOne(); Console.WriteLine("1W"); } static void fn2() { int count; Console.WriteLine("Starting thread 2"); sem2.WaitOne(); Console.WriteLine("1W"); var conn = MakeConn(); var cmd = new MySqlCommand("", conn); sem1.Release(); Console.WriteLine("1R"); sem2.WaitOne(); Console.WriteLine("2W"); using (var tns = conn.BeginTransaction()) { cmd.CommandText = "update Persons set count=count+1"; cmd.ExecuteNonQuery(); cmd.CommandText = "select count from Persons;"; count = (int)cmd.ExecuteScalar(); Console.WriteLine("count is {0}", count); sem1.Release(); Console.WriteLine("1R"); sem2.WaitOne(); Console.WriteLine("2W"); tns.Commit(); } Console.WriteLine("finished transaction 2"); sem1.Release(); Console.WriteLine("1R"); sem2.WaitOne(); Console.WriteLine("2W"); cmd.CommandText = "select count from Persons;"; count = (int)cmd.ExecuteScalar(); Console.WriteLine("count is {0}", count); //should be 11. 4 + 1x2(one each thread) += 5 from first thread == 11 sem1.Release(); Console.WriteLine("1R"); } console Starting Test 1W 2W Starting thread 2 Finish inserting. v=4 2R 1W 1R 1W Starting transaction count is 5 2R 2W count is 6 1R 1W count is 10 finished transaction 1 2R 2W finished transaction 2 1R 1W count is 10 2R 2W count is 10 1R

  • Removing a result from Queryset

    - by Enrico
    Is there a simple way to discard/remove the last result in a queryset without affecting the db? I am trying to paginate results in Django, but don't know the total number of objects for a given query. I was planning on using next/previous or older/newer links, so I only need to know if this is the first and/or last page. First is easy to check. To check for the last page I can compare the number of results with the pagesize or make a second query. The first method fails to detect the last page when the number of results in the last set equals the pagesize (ie 100 records get broken into 10 pages with the last page containing exactly 10 results) and I would like to avoid making a second query. My current thought is that I should fetch pagesize + 1 results from the db. If the queryset length equals 11, I know this is not the last page and I want to discard the last result in the queryset before passing the queryset to the template.

  • How to Compile Sample Code

    - by James L
    I'm breaking into GUI programming with android, trying to compile and analyze Lunar Lander sample program. The instructions for using Eclipse say to select "Create project from existing source" but that option doesn't exist. If I select File-New-Project I can select "Java project from Existing Ant Buildfile". Using that I've tried selecting various xml files as "Ant Buildfile" but all give me the "The file selected is not a valid Ant buildfile" error. I just want to run GUI sample projects, preferably with Eclipse. Any useful tips will be appreciated.

  • Saving Blob data from SQLite database to a file

    - by Felipe
    Hello, I'm trying to save blob data from a SQLite database (Safari cache: Cache.db) to a file, but for some reason sqlite won't read the whole blob. I eventually would like to do this in ruby, but for now something that works directly in sqlite command prompt is fine. Also, I've read all of the entries that talk about this here on stackoverflow, but most of them only discuss the performance of saving images in blobs and the one entry that does show to save blobs to file is in C# which does not help me. Here is what I've tried: sqlite select * from cfurl_cache_response limit 1; 3501|0|945281827|0|http://www.gospelz.com/components/com_jomcomment/smilies/guest.gif|2010-02-24 16:20:07 sqlite select receiver_data from cfurl_cache_blob_data where entry_ID = 3501; GIF89a( A hexdump of the original (guest.gif) file shows that sqlite stops reading the blob after the first null value: $ hexdump -C guest.gif 00000000 47 49 46 38 39 61 28 00 28 00 f7 00 00 f1 f5 fd |GIF89a(.(.......| sqlite .output test.gif sqlite select receiver_data from cfurl_cache_blob_data where entry_ID = 3501; $ hexdump -C test.gif 00000000 47 49 46 38 39 61 28 0a |GIF89a(.|

  • Is SQL used by PDO database independent?

    - by Pheter
    Different databases have slight variations in their implementations of SQL. Does PDO handle this? If I write an SQL query that I use with PDO to access a MySQL database, and later tell PDO to start using a different type of database, will the query stop working? Or will PDO 'convert' the query so that it continues to work? If PDO does not do this, are there any PHP libraries that allow me to write SQL according to a particular syntax, and then the library will handle converting the SQL so that it will run on different databases?

  • How do I return an empty result set from a procedure using T-SQL?

    - by Kivin
    I'm interested in returning an empty result set from SQL Server stored procedures in certain events. The intended behaviour is that a L2SQL DataContext.SPName().SingleOrDefault() will result in CLR null value. I'm presently using the following solution, but I'm unsure whether it would be considered bad practice, a performance hazard (I could not find one by reading the execution plan), or if there is simply a better way: SELECT * FROM [dbo].[TableName] WHERE 0 = 1; The execution plan is a constant scan with a trivial cost associated with it. The reason I am asking this instead of simply not running any SELECTs is because I'm concerned previous SELECT @scalar or SELECT INTO statements could cause unintended result sets to be served back to L2SQL. Am I worrying over nothing?

  • MySQL is returning an "column ambiguous" error when it used to work before I upgraded...

    - by Ronedog
    I recently upgraded MySQL to 5.1.41. Before the upgrade the following SQL worked (or at least I thought I remembered it working...it has been a few weeks since designing this...). Now the SQL gives me an error stating that the "archived" column is ambiguous. How can I write this differently, or is there a different problem I'm not aware of? I simply want to return the "unit_id", "lease_count" (stored in another table with a unit_id that should correspond with the "a.unit_id"), and "lease_archived_count (stored in another table with a unit_id that should correspond with the "a.unit_id"). SELECT a.unit_id, (SELECT count(*) FROM o_leases WHERE unit_id = a.unit_id AND archived = 0) as lease_count, (SELECT count(*) FROM o_leases WHERE unit_id = a.unit_id AND archived = 1) as lease_archive_count FROM p_unit a, properties b, portfolio c WHERE a.property_id = b.properties_id AND b.portfolio_id = c.portfolio_id AND a.archived = 0 Thanks for your help.

What is the easiest way of correcting this setback? Thanks in advance.

  • Grails and googleJsonAPIService

    - by Calahad
    I am using the googleJsonAPIService to manipulate users (CRUD). This is how I get the Directory instance: def getBuilder() { def builder def httpTransport = googleJsonAPIService.makeTransport() def jsonFactory = googleJsonAPIService.makeJsonFactory() def requestInitialiser = googleJsonAPIService.getRequestInitialiser() builder = new Directory.Builder(httpTransport, jsonFactory, requestInitialiser); return builder } Directory getGoogleService() { Directory googleService = getBuilder().build() return googleService; } Once I have this service, I use it to get a user's details (in my own service) for example: def query = getGoogleService().users().get(id) return handleException { query.execute() } I manually populate a DTO with the result of that query, and this is where my question comes: Is there an elegant way to have this mapping (object returned to DTO) done automatically so all I have to do is pass the class of the object to be returned? This is the structure of the object returned by google : ["agreedToTerms":true,"changePasswordAtNextLogin":false, "creationTime":"2013-11-04T04:33:35.000Z", "emails":[{"address":"[email protected]","primary":true}],...]

  • Jasper error: Caused by SQLServerException: Transaction (Process ID 58) was deadlocked on thread | c

    - by Saky
    I got the above error in my jasper report mail. The query that is used in the report is quite complicated (for me). Reading different posts I conclude that to solve this the I have to change the query to SET TRANSACTION ISOLATION LEVEL REPEATABLE READ GO BEGIN TRANSACTION ... my query ... COMMIT TRANSACTION ? I wonder if this is the correct way to solve the error and that if it has any side effects? Has it happened to anyone in the Jasper reports? Does anyone know if there is a better solution exist to the problem? (Although that I have not yet tested the above solution, if anyone can give any insight on this will be helpful.)

  • ClickOnce: How do I pass a querystring value to my app *through the installer*?

    - by Timothy Khouri
    My company currently builds separate MSI's for all of our clients, even though the app is 100% the same across the board (with a single exception, an ID in the app.config). I would like to show them that we can publish in once place with ClickOnce, and simply add a query string parameter for each client's installer. Example: http://mysite.com/setup.exe?ID=1234-56-7890 The issue that I'm having is that the above ("ID=1234...") is not being passed along to the "myapplication.application". What is happening instead is, the app is being installed successfully, and it is running the first time with an activation context, but the "ActivationUri" does not contain any query string values. Is there a way to pass query string values FROM THE INSTALLER URL to the application's launch URL? If so, how?

  • linq NullReferenceException while checking for null reference

    - by Odrade
    I have the following LINQ query: List<FileInputItem> inputList = GetInputList(); var results = from FileInputItem f in inputList where ( Path.GetDirectoryName(f.Folder).ToLower().Trim() == somePath || Path.GetDirectoryName(f.Folder).ToLower().Trim() == someOtherPath ) && f.Expression == null select f; Every time this query is executed, it generates a NullReferenceException. If I remove the condition f.Expression == null or change it to f.Expression != null, the query executes normally (giving the wrong results, of course). The relevant bits of FileInputItem look like this: [Serializable] public class FileInputItem { [XmlElement("Folder")] public string Folder { get; set; } [XmlElement("Expression")] public string Expression { get; set; } /*SNIP. Irrelevant properties */ } I'm new to LINQ to objects, so I'm probably missing something fundamental here. What's the deal?
