  • Changing the Column order/adding Newcolumn for existing Table in SQLServer2008

    - by rmdussa
    Hi I have situation where I need to change the order of the columns/adding new columns for existing Table in SQLServer2008, It is not allowing me to do without drop and recreate. But That is in production system and having data in that table. I can take backup of the data, and Drop the existing table and change the order/add new columns and recreate it, insert the backup data into new Table. Is there any best way to do this without dropping and recreating.I think SQLServer 2005 will allow this process without dropping and recreating while changing to existing table structure. Thanks

  • Nesting, grouping Sqlite syntax?

    - by Linda
    I can't for the life of me figure out this Sqlite syntax. Our database contains records like: TX, Austin OH, Columbus OH, Columbus TX, Austin OH, Cleveland OH, Dayton OH, Columbus TX, Dallas TX, Houston TX, Austin (State-field and a city-field.) I need output like this: OH: Columbus, Cleveland, Dayton TX: Dallas, Houston, Austin (Each state listed once... and all the cities in that state.) What would the SELECT statement(s) look like?

  • Override delete behaviour in NHibernate

    - by David
    Hi all In my application users cannot truly delete records. Rather, the record's Deleted field gets set to 1, which hides it from selects. I need to maintain this behaviour and I'm looking into whether NHibernate is appropriate for my app. Can I override NHibnernate's delete behaviour so that instead of issuing DELETE statements, it issues UPDATES, as described above? I would obviously also need to override its SELECT behaviour to include the 'AND Deleted = 0' clause. Or read from a view instead. I dunno. TIA for your advice. David

  • complex MySQL Order by not working

    - by Les Reynolds
    Here is the select statement I'm using. The problem happens with the sorting. When it is like below, it only sorts by t2.userdb_user_first_name, doesn't matter if I put that first or second. When I remove that, it sorts just fine by the displayorder field value pair. So I know that part is working, but somehow the combination of the two causes the first_name to override it. What I want is for the records to be sorted by displayorder first, and then first_name within that. SELECT t1.userdb_id FROM default_en_userdbelements as t1 INNER JOIN default_en_userdb AS t2 ON t1.userdb_id = t2.userdb_id WHERE t1.userdbelements_field_name = 'newproject' AND t1.userdbelements_field_value = 'no' AND t2.userdb_user_first_name!='Default' ORDER BY (t1.userdbelements_field_name = 'displayorder' AND t1.userdbelements_field_value), t2.userdb_user_first_name; Edit: here is what I want to accomplish. I want to list the users (that are not new projects) from the userdb table, along with the details about the users that is stored in userdbelements. And I want that to be sorted first by userdbelements.displayorder, then by userdb.first_name. I hope that makes sense? Thanks for the really quick help! Edit: Sorry for disappearing, here is some sample data userdbelements userdbelements_id userdbelements_field_name userdbelements_field_value userdb_id 647 heat 1 648 displayorder 1 - Sponsored 1 645 condofees 1 userdb userdb_id userdb_user_name userdb_emailaddress userdb_user_first_name userdb_user_last_name 10 harbourlights [email protected] Harbourlights 1237 Northshore Blvd, Burlington 11 harbourview [email protected] Harbourview 415 Locust Street, Burlington 12 thebalmoral [email protected] The Balmoral 2075 & 2085 Amherst Heights Drive, Burlington

  • Synonym for "Many-to-Many" relationship (relational databases)

    - by Byron
    What's a synonym for a "many-to-many" relationship? I've finished writing an object-relational mapper but I'm still stumped as to what to name the function that adds that relation. addParent() and addChild() seemed quite logical for the many-to-one/one-to-many and addSuperclass() for one-to-one inheritance, but addManyToMany() would sound quite unintuitive to an object-oriented programmer. addSibling() or addCousin() doesn't really make sense either. Any suggestions? And before you dismiss this as a non-programming question, please remember that consistent naming schemes and encapsulation are pretty integral to programming :)

  • Use SQL Result to Query second time and grab more results via php

    - by maxwell
    I am grabbing a list of school names from a database. When the user clicks on the school name, i want the code to fetch 2-3 other attributes related to the school name that the user has clicked on. My code for the single school name list: $query = mysql_query("Select schoolname, product, username, password from credentials c join products p on p.productid = c.productid join schools s on s.schoolid = c.schoolid join icons i on i.productid = p.productid order by s.schoolname"); echo '<ul>'; while($row = mysql_fetch_array($query)) { echo "<li> <a href='#'>" . $row['schoolname'] . "</a> </li>"; } echo ''; Current Output: School A School A School B School B School B School C School C Expected Output: School name displayed only once (distinct won't work because each school name has 2-3 product credentials School A School B School C Ability for User to click on a school. then the school names underneath will move down (toggle effect) and user can see product, username and password displayed for the school clicked (for example: user clicked on School A) School A productname1, username, password productname2, username, password School B School C

  • Why isn't "String or Binary data would be truncated" a more descriptive error?

    - by rwmnau
    To start: I understand what this error means - I'm not attempting to resolve an instance of it. This error is notoriously difficult to troubleshoot, because if you get it inserting a million rows into a table 100 columns wide, there's virtually no way to determine what column of what row is causing the error - you have to modify your process to insert one row at a time, and then see which one fails. That's a pain, to put it mildly. Is there any reason that the error doesn't look more like this? String or Binary data would be truncated Error inserting value "Some 18 char value" into SomeTable.SomeColumn VARCHAR(10) That would make it a lot easier to find and correct the value, if not the table structure itself. If seeing the table data is a security concern, then maybe something generic, like giving the length of the attempted value and the name of the failing column?

  • Create/Edit/Save data in a jQuery pop-up for ASP.NET-MVC and Linq2Sql

    - by RememberME
    I have a MVC page which allows creation and editing of a subcontract. When the user has to select a company for the subcontract, I would like for them to have the option to create a new company. I've made a jQuery pop-up with the company fields, but I don't know how to then save this information to the company table. I would also like to be able to use the same pop-up to allow the user to edit the information for an existing company, but need direction in how to send the information to the pop-up.

  • Strategy Design Pattern -- *dynamic* !!!

    - by alexeypro
    My application will have different strategies for my objects. What's the best way of implementing that? I would really love the case when we can make strategy classes implementation dynamically loaded from, say, some relational database. Not sure how do that better, though. What's the best approach? Idea is that say we want to apply to object MyObj strategy Strategy123 then we just load from database by ID 123 the object, deserialize it, get the Strategy class, and use it with MyObj. The maintenance while sounds easier from the first look can be a pain in the long run if Strategy interfaces changes, etc. What can I do also? I want to find solution when I should be keeping Strategy classes in codebase -- just for the sake that I don't need code change and re-deployment of the application if my Strategy changes, or I add new strategy. Please advise!
