  • Building resultset using collection object

    - by Bhaskara Krishna Mohan Potam
    Hi, I had an issue in building the resultset using java. Here it goes... I am storing a collection object which is organized as row wise taken from a resultset object and putting the collection object(which is stored as vector/array list) in cache and trying to retrieve the same collection object. Here i need to build back the resultset again using the collection object. Now my doubt is building the resultset in this way possible or not? Please let me know asap. Thanks in advance, Bhaskar

  • How to retrieve the size of a database in restoring mode

    - by Marc Wittke
    With pure SQL - how to do it? I doubt it is possible, since even the SQL Management Studio fails to show the size of such a database in the UI. Already tried: exec sp_helpdb 'DbInRecMode' ...won't show anything; exec sys.sp_helpfile 'DbInRecMode' ... something like file not found (Msg 15325) Main pitfall seems to be the issue, that select * from DbInRecMode.dbo.sysfiles won't work when the database is in restoring mode. Any ideas?

  • Get an object by its objectGUID using ldapsearch

    - by orsogufo
    If I have the objectGUID attribute as returned by the ldapsearch command, how can I search the whole directory for an object with that objectGUID? For example, if I search a user getting its objectGUID, I get the following: ldapsearch -x -D $MyDn -W -h $Host -b "dc=x,dc=y" "(mail=something)" objectGUID # 7f435ae312a0d8197605, p, Externals, x.y dn: CN=7f435ae312a0d8197605,OU=p,DC=x,DC=y objectGUID:: b+bSezFkKkWDmbIZiyE5rg== Starting from the value b+bSezFkKkWDmbIZiyE5rg==, how can I create a query string to get that object?

  • Two different definitions of database schema

    - by AspOnMyNet
    a) I found two definitions of schema: FIRST - A set of information that describes a table is known as a schema, and schemas are used to describe specific tables within a database, as well as entire databases (and the relationship between tables in them, if any). SECOND - A database schema is a way to logically group objects such as tables, views, stored procedures etc. Think of a schema as a container of objects. I assume the two descriptions describe entirely different concepts, which just happen to use the same name? b) A database schema is a way to logically group objects such as tables, views, stored procedures etc. Think of a schema as a container of objects. If I understand the above definition correctly, then database schema is similar to a namespace, only difference being that we can assign access permissions to database schema, while same can’t be done with namespaces? thanx

  • Error when trying to use PDO object

    - by Nate
    EDIT: I'm going to put my code in here due to comments below. So sit tight for a few minutes ;-) Thanks! I'm an inexperienced php programmer and only found out about PDO a few days ago. I'm now trying to port my website code over to using PDO, but I am getting an error when I try to use the PDO object that I create. I'm using a CMS on my website, and it makes building page output kind of complicated, but I've tried to draw the structure of what is being called below: index.php -class myClass defined --method myFunction defined (it gets called on pageload & returns the page output) ---include file1.php ----require_once('mysql_connect.php') (creates pdo object) ----*I can use the pdo object here successfully* ----require_once('file2.php') -----require_once('mysql_connect.php') -----function myFunction2 defined ------*trying to use the pdo object here results in the error* The error I'm getting is: Fatal error: Call to a member function prepare() on a non-object in /home/rgcpanel/public_html/account/account_functions.php on line 147 Any idea what's going on?

  • Getting an alert when my oracle database goes up or down

    - by CodeSlave
    How can I get an e-mail alert when my oracle database comes up or down? I have a database that I need to know when it goes down (it would be nice to know if it has come back up), preferably from a remote machine. Conceivably I could hack together something that TNSPings my DB and e-mails me when that changes, but I'm hoping there's a free package out there. Something that would run on windows. Any strong recommendations?

  • Specialization hierarchy in a domain-model

    - by devoured elysium
    I'm trying to make the domain model of a management system. I have the following kinds of persons in this system: employee manager top mananger I decided to define a User, from where employee, manager and top manager will specialize from. What I don't know is what kind of specialization hierarchy I should choose from. I thought of two ways: or Which might be preferable and why? As a long time coder, every time I try to do a domain-model, I have to fight against the idea of trying to think in how I'm going to code this. From what I've understood, I should not think about those matters in the domain-model, only in object relationships. I don't have to think of code duplication or any of these kind of details here, so I can't really pick any of the options over the other. Thanks

  • Database error when deleting entry in my rails app.

    - by Danny McClelland
    Hi Everyone...again! I have almost everything in my Rails app working, with the exception of detroying entries. I can destroy entries for companies but not kases and people. The following error show when trying to do so: SQLite3::SQLException: no such column: kases_people.kase_id: SELECT * FROM "kases" INNER JOIN "kases_people" ON "kases".id = "kases_people".kase_id WHERE ("kases_people".person_id = 5 ) I suspect this is an error with the party model for the has_many :through associations that I dont fully understand. You can find an up to date version of the app at www.github.com/dannyweb/surveycontrol Thanks, Danny

  • SQL Server database filled the hard drive and freeing up space isn't possible

    - by Jon
    I have a database in SQL Server 2008 on a 1Tb hard drive and it filled the drive, there is only 4Kb free. The MDF file is 323Gb and the LDF is 653Gb. The hard disk this DB is on has no other files on it other than the MDF and LDF so it's impossible to free up any space on the drive. The main hard disk is smaller but there is enough room to transfer the MDF to that drive, in case that helps. This server is overseas at a customer site and it's not possible at the moment to add more disk space to the server. It's also not possible to delete any records because the DB is in a failed mode (due to no disk space) and it doesn't respond to most commands. The Db is currently in full recovery mode which is why the LDF file is so large. This DB really doesn't need to be in full recovery so going forward we plan on switching it to simple mode which will save us a lot of space. I also don't care about losing the LDF file, but I need all of the data. I've spent a lot of time looking for a way out of this problem but everything I've found first involves either freeing up disk space or adding more disk space, neither of which is an option at this time. I'm stuck and any help would be greatly appreciated. I get the following log when trying to switch the DB to online mode. Msg 945, Level 14, State 2, Line 3 Database 'DBNAME' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details. Msg 5069, Level 16, State 1, Line 3 ALTER DATABASE statement failed. Msg 1101, Level 17, State 12, Line 3 Could not allocate a new page for database 'DBNAME' because of insufficient disk space in filegroup 'DEFAULT'. Create the necessary space by dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. I've found the following solutions but none work due to having no disk space on that drive, and since the DB is in a failed state I can't run most commmands. - DBCC SHRINKFILE - can't be run because doing a 'use DBNAME' fails - Detaching the DB and then changing the location of the MDF/LDF files, this fails because the DB is in an offline mode so you can't run detach. I'm at a loss about what else to try. Thanks.

  • Object drag delay issue

    - by Johnny Darvall
    I have this code that drags stuff around perfectly in IE - however in firefox the onmousedown-drag of the object does not immediately drag but shows the no-entry cursor and then after onmouseup the object drags around freely. The object does stop draging on the next onmouseup. The object should only drag in the onmousdown state, while the onmousup call should cancel the drag by making j_OK=0. I think it may have something to do with the image inside... the object: <em style=position:absolute;left:0;top:0;width:32;height:32;display:block> < img src=abc.gif onmousedown=P_MV(this.parentNode) style=position:absolute;left:0;top:0;width:inherit> </em> function P_MV(t) { p_E=t j_oy=parseInt(p_E.style.top) j_ox=parseInt(p_E.style.left) j_OK=1 document.onselectstart=function(){return false} document.onmousemove=P_MVy } function P_MVy(e) { if(j_OK) { p_E.style.top=(j_FF?e.clientY:event.clientY)-j_y+j_oy p_E.style.left=(j_FF?e.clientX:event.clientX)-j_x+j_ox } return false }

  • deploying vb.net app with database on server

    - by vbNewbie
    I have an application that accesses a sql server 2008 database. The server and database is stored on my local harddrive and I would like to learn to scale this up to having multiple users in our office access the application which I will i deploy on a server. For now the database will stay on my pc until I am ready to put it on a dedicated server for myself but for now how do I allow the application still to access my database. Here is my current connection string: <add key="ConnectionString" value="Data Source=.;Initial Catalog=SearchEngine;User ID=sa;Password=pss;Trusted_Connection=False;" /> Now I know how to deploy a general vb.net application but what I dont know is what to do with the database. Please help with any advice

  • How can I define pre/post-increment behavior in Perl objects?

    - by Zaid
    Date::Simple objects display this behavior. In the case of Date::Simple objects, $date++ returns the next day's date. Date::Simple objects are immutable. After assigning $date1 to $date2, no change to $date1 can affect $date2. This means, for example, that there is nothing like a set_year operation, and $date++ assigns a new object to $date. How can one custom define the pre/post-incremental behavior of an object, such that ++$object or $object-- performs a particular action? I've skimmed over perlboot, perltoot, perltooc and perlbot, but I don't see any examples showing how this can be done.

  • secure data transport between web server and database server

    - by atypicalgeek
    I asked this question in stackoverflow and it was suggested to try here so here goes... I'm planning on provisioning a web server and database server in a server farm environment. They will be in the same network but not in the same domain, both windows server 2008 and the database server is sql server 2008. My question being, what is the best way to secure data in transport between the servers? I've looked into IPSEC and SSL but not sure how to go about implementing either.

  • Method hiding with interfaces

    - by fearofawhackplanet
    interface IFoo { int MyReadOnlyVar { get; } } class Foo : IFoo { int MyReadOnlyVar { get; set; } } public IFoo GetFoo() { return new Foo { MyReadOnlyVar = 1 }; } Is the above an acceptable way of implementing a readonly/immutable object? The immutability of IFoo can be broken with a temporary cast to Foo. In general (non-critical) cases, is hiding functionality through interfaces a common pattern? Or is it considered lazy coding? Or even an anti-pattern?

  • dynamic behavior of factory class

    - by manu1001
    I have a factory class that serves out a bunch of properties. Now, the properties might come either from a database or from a properties file. This is what I've come up with. public class Factory { private static final INSTANCE = new Factory(source); private Factory(DbSource source) { // read from db, save properties } private Factory(FileSource source) { // read from file, save properties } // getInstance() and getProperties() here } What's a clean way of switching between these behaviors based on the environment. I want to avoid having to recompile the class each time.

  • Do i need to insert one fake row in database ?

    - by Ankit Rathod
    Hello, I have few tables like example. Users Books UsersBookPurchase UID BookId UserId UName Name BookId Password Price Email This is fine. I am having my own login system but i am also using some 3rd party to validate like OpenID or facebook Authetication. My question is if the user is able to log in successfully using OpenID or facebook Authentication, what steps do i need to do i.e do i have to insert one fake row in Users table because if i do not insert how will integrity be maintained. I mean what user id should i insert in UsersBookPurchase when the person who has logged in using Facebook Authentication has made a purchase because the UserId is reference key from Users table. Please give me a high level overview of what i need to do because this is fairly common scenario. Thanks in advance :)

  • ADO.NET Multiple simultaneous reads from an open database.

    - by Deverill
    Answer not needed - my logic was wrong and this question is invalid. Charles helped me see where I went off-tracks. Thanks I have a utility that moves data from one source to another. In the process of writing the record I check to see if it exists and do an update/insert as necessary. The difficulty I have is that as I'm writing the main record info there is a 2nd table for "custom data" that I have to check to see if it exists and do an update/insert for that as well. Example: I may be loading a pencil sharpener that may or may not exist. While I'm writing it into destination it has characteristics such as style, color, etc. and each of them may or may not exist. As written I seem to need to have 2 DataReaders open, one for the sharpener and one to check for and update color. I am new to ADO.NET, but not to programming and it's more complicated than I listed but for sanity's sake I didn't put all the details. My question is: What am I missing? You can't have 2 readers open at the same time on a connection, yet I can't close the first if I'm stepping through all products. It seems inefficient to have 2 connections, readers, etc. for this. Is there a feature of ADO.NET DBs that I'm missing? How would you do it? Thanks!

  • Database Design: A proper table design for large number of column values.

    - by Jake
    I wish to perform an experiment many different times. After every trial, I am left with a "large" set of output statistics -- let's say, 1000. I would like to store the outputs of my experiments in a table, but what's the best way...? Option 1 Have a table with 1000 columns. Seems like a bad idea. What if the number of statistics one day exceeds the maximum number of columns? Option 2 Have a table with three columns. Let's say, ID, StatisticType, and StatisticValue. That way, you can have as many statistics as you want. However, reading a single experiments statistics becomes more complicated. Moreover, what if different statistics are different data types?? Any suggestions?

  • Upload database backup from mysql to Amazon S3 or Glacier without creating local file

    - by Rubem Azenha
    Is there a tool that makes possible to backup a Mysql database to Amazon S3 or Amazon Glacier without having o create a local file with the database contents? Something like that: mysqldump -u root -ppass -h host --all-databases | magical-s3-tool s3-bucket backup-yyyy-mm-dd.sql This magical tool would use the pipe data and transfer the backup data directly to S3, without creating a local file.
