  • Can splitting .MDB files into segments help with stability?

    - by Craig Johnston
    Is this a realistic solution to the problems associated with larger .mdb files: split the large .mdb file into smaller .mdb files have one 'central' .mdb containing links to the tables in the smaller .mdb files How easy would it be to make this change to an .mdb backed VB application? Could the changes to the database be done so that there are no changes required to the front-end application?

  • Change date format (in DB or output) to dd/mm/yyyy - PHP MySQL

    - by Jess
    MySQL stores the date in my database (by default) as 'YYYY-MM-DD' The field type for my date is 'DATE' (I do not need any time storage).. Is there a simple way to change it by default to DD/MM/YYYY ? I call up different dates in 2 different tables, and no where in any of my code do I have anything resembling a date variable or anything! Hopefully this is a straight forward change?

  • Dropdownlist width in IE

    - by NimsDotNet
    In IE, the dropdown-list takes the same width as the dropbox (i hope i am making sense) whereas in Firefox the dropdown-list's width varies according to the content. This basically means that i have to make sure that the dropbox has to be wide enough to display the longest selection possible. this makes my page look very ugly :( Is there any workaround for this problem? How can i uses CSS to set different widths for dropbox and the dropdownlist?

  • Perl daemon script for message queue hanging for 20 seconds after each process. Why?

    - by Mike Diena
    I have daemon script written in Perl that checks a database tables for rows, pulls them in one by one, sends the contents via HTTP post to another service, then logs the result and repeats (only a single child). When there are rows present, the first one is posted and logged immediately, but every subsequent one is delayed for around 20 seconds. There are no sleep()'s running, and I can't find any other obvious delays. Any ideas?

  • how to avoid deadlock in mysql

    - by noam
    I have the following query (all tables are innoDB) INSERT INTO busy_machines(machine) SELECT machine FROM all_machines WHERE machine NOT IN (SELECT machine FROM busy_machines) and machine_name!='Main' LIMIT 1 Which causes a deadlock when I run it in threads, obviously because of the inner select, right? The error I get is: (1213, 'Deadlock found when trying to get lock; try restarting transaction') How can I avoid the deadlock? Is there a way to change to query to make it work, or do I need to do something else?

  • Foreign Keys Duplicated in DataGridView

    - by John Doe
    I created a Windows Forms Application to which I added a DataGridView and LINQ to SQL Classes from one of my databases. I can successfully bind one of my database's tables to my DataGridView: var dataSource = from c in _db.NetworkedEquipments select c; dataGridView1.DataSource = dataSource; However, the foreign keys get duplicated, that is, the columns appear twice. How can I prevent this?

  • Select most recent record in sub child

    - by Omar
    I have the following tables/columns: Parent: ParentID Child: ChildID ParentID SubChild: SubChildID ChildID Date Parent has 1 to Many relationship with Child Child has 1 to Many relationship with SubChild For every Parent, I need to get the SubChild with the most recent Date value. How can I do this using SQL. I've tried using MAX(Date), but I can't seem to figure out how to join Parent and Child successfully. The ideal result set would contain all the Parents joined with all the SubChild columns of the latest record. Note: using MS SQL 2005+

  • No getdate() function in Enterprise PostgreSQL

    - by Suezy
    Hi guys, do you have any idea on how to have getdate() function in enterprise postgresql? I upgraded to EDB-PSQL, and now when I tried to restore old data from the free PSQL, it returns error on some tables since there is no getdate(). I believe this should automatically be created upon creating new database? But it didn't. :( Only now() function. Can I create the function instead? Help!

  • running same query in different databases

    - by user316833
    I wrote a query that I want to run in several access databases. I have 1000+ access databases with the same tables (same names, same fields). So far, I have been manually copying this query from a txt file to the sql view in the access query design screen for each database and then run it. I did not need to change the query language - everything is the same for the 1000 databases. Is there a way to automate this?

  • Is there a way to get photo tags and new friendship type events by querying the FQL stream table?

    - by Fletcher Moore
    When you look at your stream on the Facebook website, events such as "FriendX was tagged in an album", "FriendY is attending EventZ", and "FriendK and FriendL are now friends". I've tried various "vague" queries on the stream table, and so far I have been unable to get these types of events. Is this possible, or do I need to query the all of the other tables and write a ton of logic to try to figure out which new events to show and how to show them?

  • Layout issue regarding a JQuery smoothDivScroll

    - by MichaelMcCabe
    Hi all. I have been scratching my head for a while on this one. I dont really play around with HTML formatting that often. I have a smoothDivScroll using JQuery (http://maaki.com/thomas/SmoothDivScroll/) to scroll through dynamically generated images. What I want it for, is to have multiple small images lined up right next to each other, and each image has a section of writting underneath. about 25 images, 140px width each in a 7560px span. I acheived this great by putting a table inside the div, and each image inside a<td>.This works problem i have, is that i need the slider to start from the furthest RIGHT image, and slide automatically left. This is acheived by (if you look at the link above) - startAtElementId: But if I am using a table inside the div, it is taking the TABLE as a element and not the TD... so it doesnt work. I know this because if I change every image to be inside tables (i.e 25 tables), it works... but obviously then the formatting is not how I want. Can anyone think of a way I can use this slider (modifications to the js code or not), with 25 images that NEED to be right next to each other, no gap. I guess this is more of a formatting question, than about the slider. Because I only know ONE way of doing what I want, and thats to have below which will not alow me to set startAtElementId. <div class="scrollableArea"> <table width="7560px" class="index-body"> <tr> <td width="140px"><center><a onclick="__doPostBack('getEarlierDate');" ><img src="../images/olderGraphs.gif" width="140" height="60"></a>Click for more</center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked25');" ><cewolf:img chartid="verticalbar25" renderer="cewolf" width="300" height="60"/></a><c:out value="${date25}"/></center></td> <td width="300px"><center><a onclick="__doPostBack('chartClicked24');" ><cewolf:img chartid="verticalbar24" renderer="cewolf" width="300" height="60"/></a><c:out value="${date24}"/></center></td> and so on

    Hello everyone, I am using SQL Server 2008 Enterprise DB and using the new Merge statement (when source and target are both SQL Server 2008 DB tables), and it works well.

  • Generate A Simple Read-Only DAL?

    - by David
    I've been looking around for a simple solution to this, trying my best to lean towards something like NHibernate, but so far everything I've found seems to be trying to solve a slightly different problem. Here's what I'm looking at in my current project: We have an IBM iSeries database as a primary repository for a third party software suite used for our core business (a financial institution). Part of what my team does is write applications that report on or key off of a lot of this data in some way. In the past, we've been manually creating ADO .NET connections (we're using .NET 3.5 and Visual Studio 2008, by the way) and manually writing queries, etc. Moving forward, I'd like to simplify the process of getting data from there for the development team. Rather than creating connections and queries and all that each time, I'd much rather a developer be able to simply do something like this: var something = (from t in TableName select t); And, ideally, they'd just get some IQueryable or IEnumerable of generated entities. This would be done inside a new domain core that I'm building where these entities would live and the applications would interface with it through a request/response service layer. A few things to note are: The entities that correspond to the database tables should be generated once and we'd prefer to manually keep them updated over time. That is, if columns/tables are added to the database then we shouldn't have to do anything. (If some are deleted, of course, it will break, but that's fine.) But if we need to use a new column, we should be able to just add it to the necessary class(es) without having to re-gen the whole thing. The whole thing should be SELECT-only. We're not doing a full DAL here because we don't want to be able to break anything in the database (even accidentally). We don't need any kind of mapping between our domain objects and the generated entity types. The domain barely covers a fraction of the data that's in there, most of it we'll never need, and we would rather just create re-usable maps manually over time. I already have a logical separation for the DAL where my "repository" classes return domain objects, I'm just looking for a better alternative to manual ADO to be used inside the repository classes. Any suggestions? It seems like what I'm doing is just enough outside the normal demand for DAL/ORM tools/tutorials online that I haven't been able to find anything. Or maybe I'm just overlooking something obvious?
