  • How to: Avoid Inserting Related Entities?

    - by niaher
    I have this schema: I want to insert an Order with OrderItems into database, so I wrote this method: public void SaveOrder(Order order) { using (var repository = new StoreEntities()) { // Add order. repository.Orders.AddObject(order); // Add order items. foreach (OrderItem orderItem in order.OrderItems) { repository.OrderItems.AddObject(orderItem); } repository.SaveChanges(); } } Everything is inserted just fine, except that new Product records are inserted too, which is not what I want. What I want is to insert Order and its OrderItems, without going any further down the object graph. How can that be achieved? Any help is really appreciated, thank you.

  • No difference between nullable:true and nullable:false in Grails 1.3.6?

    - by knorv
    The following domain model definition .. class Test { String a String b static mapping = { version(false) table("test_table") a(nullable: false) b(nullable: true) } } .. yields the following MySQL schema .. CREATE TABLE test_table ( id bigint(20) NOT NULL AUTO_INCREMENT, a varchar(255) NOT NULL, b varchar(255) NOT NULL, PRIMARY KEY (id) ) ENGINE=InnoDB DEFAULT CHARSET=utf8; Please note that a and b get identical MySQL column definitions despite the fact a is defined as non-nullable and b is nullable in the GORM mappings. What am I doing wrong? I'm running Grails 1.3.6.

  • Why is my BeginInvoke method not async?

    - by Petr
    Hi, In order to avoid freezing of GUI, I wanted to run method connecting to DB asynchronously. Therefore I have written this: DelegatLoginu dl = ConnectDB; IAsyncResult ar=dl.BeginInvoke(null, null); bool result = (bool)dl.EndInvoke(ar); But it is still freezing and I do not understand why - I though BeginInvoke assures that method it references is run in another thread. Thank you!

  • T-SQL - Is there a (free) way to compare data in two tables?

    - by RPM1984
    Okay so i have table a and table b. (SQL Server 2008) Both tables have the exact same schema. For the purposes of this question, consider table a = my local dev table, table b = the live table. I need to create a SQL script (containing UPDATE/DELETE/INSERT statements) that will update table b to be the same as table a. This script will then be deployed to the live database. Any free tools out there that can do this, or better yet a way i can do it myself? I'm thinking i probably need to do some type of a join on all the fields in the tables, then generate dynamic sql based on that. Anyone have any ideas?

  • How do I make a daemon into a stream in PHP

    - by Itay Moav
    I have a daemon (written in C, but I assume it does not really matter) which outputs messages with printf, and can get input and do stuff with this input (again, not really important what, but he sends those messages to a different machine to be saved there in the DB). My question, how can I make this daemon to be a stream in PHP, so I can hook the input/output of, for example, file_put_contents to this stream.

  • CF Client Variables: is the CDATA - CGLOBAL relationship always 1:1?

    - by ciaranarcher
    Hi We've noticed something odd with our Coldfusion 8 client variables DB. We have many more (about 3 times as many) CGlobal entries as we have CData entries. I would have assumed that the relationship would be 1:1 on the cfid column. Has any one else noticed this before? I have ruled out old data, my sample is less than 3 hours old. We're using SQL Server 2000 to host the tables. Thanks in advance, Ciaran

  • Help getting the following create table function to work with mysql and C#

    - by Matt
    string createTable = "CREATE TABLE IF NOT EXISTS " + m_strDatabase + "_TimeLogs (logName VARCHAR(16), logTime INTEGER, logCountry TEXT, UNIQUE(logName)) TYPE=MyISAM;"; When this runs, no table is created. No errors either. Im using an ODBC connector. the variable passes in the db name, so that the table created would be users_TimeLogs if the database was called users for example. Am I doing something wrong?

  • JPA polymorphic oneToMany

    - by bob
    I couldn't figure out how to cleanly do a tag cloud with JPA where each db entity can have many tags. E.g Post can have 0 or more Tags User can have 0 or more Tags Is there a better way in JPA than having to make all the entities subclass something like Taggable abstract class? Where a a Tag entity would reference many Taggables. thank you

  • SQL Complex Select - Trouble forming query

    - by JoshSpacher
    I have three tables, Customers, Sales and Products. Sales links a CustomerID with a ProductID and has a SalesPrice. select Products.Category, AVG(SalePrice) from Sales inner join Products on Products.ProductID = Sales.ProductID group by Products.Category This lets me see the average price for all sales by category. However, I only want to include customers that have more than 3 sales records or more in the DB. I am not sure the best way, or any way, to go about this. Ideas?

  • My store returns no code id and breaks 404 error. Magento

    - by numerical25
    I know what the issue is but I dont know how to fix it. I just migrated my magento store locally and I guess possibly some data may have been lost when transferring the DB. the DB is very large. Anyhow, when I login to my admin page, I get a 404 error, page was not found. I debugged the issue and got down to the wire. The exception is thrown in Mage/Core/Model/App.php. Line 759 to be exacted. The following is a snippet. Mage/Core/Model/App.php if (empty($this->_stores[$id])) { $store = Mage::getModel('core/store'); /* @var $store Mage_Core_Model_Store */ if (is_numeric($id)) { $store->load($id); // THIS ID IS FROM Mage_Core_Model_App::ADMIN_STORE_ID and its empty which causes the error } elseif (is_string($id)) { $store->load($id, 'code'); } if (!$store->getCode()) { // RETURNS FALSE HERE BECAUSE NO ID Specified $this->throwStoreException(); } $this->_stores[$store->getStoreId()] = $store; $this->_stores[$store->getCode()] = $store; } The store returns null because $id is null so it therefore does not load any model which explains why it returns false when calling getCode() [EDIT] If you want clarification, please ask for more before voting my post down. Remember I am still trying to get help not get neglected. I am using Version 1.4.1.1. When I type in the URL for admin, I get a 404 page. I walked through the code thouroughly and found that the Model MAGE_CORE_MODEL_STORE::getCode(); Returns Null which triggers the exception. and ends the script. I do not have any other detail. I further troubleshooted the issue by checking the database and that is what the screen shot is. Showing that there is infact data in the Code Colunn. So my question is why is the Model returning a empty column when the column clearly has a value. What can I do to further troubleshoot and figure out why its not working [EDIT UPDATE NEW] I did some research. the reason its returning NULL is because the store ID is null being passed Mage::getStoreConfigFlag('web/secure/use_in_adminhtml', Mage_Core_Model_App::ADMIN_STORE_ID); // THIS IS THE ID being specified Mage_Core_Model_App::ADMIN_STORE_ID has no value in it, so this method throws the exception. Not sure why how to fix this.

  • Restricting deletion with NHibernate

    - by FrontSvin
    I'm using NHibernate (fluent) to access an old third-party database with a bunch of tables, that are not related in any explicit way. That is a child tables does have parentID columns which contains the primary key of the parent table, but there are no foreign key relations ensuring these relations. Ideally I would like to add some foreign keys, but cannot touch the database schema. My application works fine, but I would really like impose a referential integrity rule that would prohibit deletion of parent objects if they have children, e.i. something similar 'ON DELETE RESTRICT' but maintained by NHibernate. Any ideas on how to approach this would be appreciated. Should I look into the OnDelete() method on the IInterceptor interface, or are there other ways to solve this? Of course any solution will come with a performance penalty, but I can live with that.

  • Convert a time to specified time zone using C#?

    I'm working on an application in C# with .Net 3.5.

Now I want to convert any date time value into this timezone value considering the daylight saving value. Any help is appreciated. Thanks

  • Some way of getting just the data part from a web service returning a DataTable?

    - by simendsjo
    I'm using an external web service that returns a DataTable. There's a couple of problems with this. The first is that there are over 20,000 columns, and .Net crashes when trying to convert the xml to a DataTable. I have to use Mono to make this work. The other problem is that it takes a lot of time to fetch all the column information. The columns "never" changes (and when they do, I know about it in advance). I would like to just fetch the data part, and load the schema from a local file. I very much doubt this is possible, but I thought I could ask here just in case.

  • HibernateTemplate alwaysUseNewSession

    - by DD
    Hi, I had a problem where I was using the hibernate template to do most of my DB work but I had a part of the system that directly accessed the session to do batch persisting. I noticed that the hibernate template session was old and would be storing cached values which didnt take into account the objects save with the session directly. What are the drawbacks of using alwaysUseNewSession? This fixes the problem as I always get up-to-date objects. Thanks.

  • SQL CONNECTION best Practices

    - by george9170
    Currently there is discussion as to what are the pros and cons of having a single sql connection architecture. To elaborate what we are discussing is, at application creation open a sql connection and at application close or error closing the sql connection. And not creating another connection at all, but using just that one to talk with the DB. We are wondering what the community thinks.

Any guidance would be greatly appreciated.

  • When should I think about implementing my User authentication / session?

    - by Jason N
    After spending some time wireframing my ideas, I want to start building my rails app. However, I'm well aware that later down the line I'd like to consider multiple user accounts. Should I be thinking about the implementation of this from this early stage, or is this something I can implement without too much fuss later? It seems like something that would be stupid to attempt later, but part of me just wants to get the guts of the thing working - a couple of simply forms and writing/reading some stuff from the db.

  • Efficient SQL to count an occurrence in the latest X rows

    - by pulegium
    For example I have: create table a (i int); Assume there are 10k rows. I want to count 0's in the last 20 rows. Something like: select count(*) from (select i from a limit 20) where i = 0; Is that possible to make it more efficient? Like a single SQL statement or something? PS. DB is SQLite3 if that matters at all...
