  • Database mirroring login failure attempts on mirror server

    - by Chandan
    I have configured database mirroring between two servers at a distance 40 miles away from each other. Server specifications: SQL Server 2008,Standard Edition 64-bit This is same for principal,mirror and witness. The configuration is high-safety with automatic failover Initially we tested our .net application(web application) on both the principal and mirror and made sure that the login is not orpahned. Things run fine generally.But sometimes on the mirror server,I see login failed attempts: Login failed for user 'd0main\user'. Reason: Failed to open the explicitly specified database. [CLIENT: xx.xx.x.x] Message Error: 18456, Severity: 14, State: 38. This error appears 3-4 times a day but not more than that. My question to the experts is:If the principal is alive so why the application tries to connect to mirror.The default time-out for a .net webpage is 30 seconds,so is it possible that the application tries to connect principal and after 30 seconds even if principal is alive,it assumes that it is dead and thus tries to open a connection to mirror where it fails. Please help me with this problem.

  • Why do we need to put N before strings in Microsoft SQL Server?

    - by user61752
    I'm learning T-SQL. From the examples I've seen, to insert text in a varchar() cell, I can write just the string to insert, but for nvarchar() cells, every example prefix the strings with the letter N. I tried the following query on a table which has nvarchar() rows, and it works fine, so the prefix N is not required: insert into [TableName] values ('Hello', 'World') Why the strings are prefixed with N in every example I've seen? What are the pros or cons of using this prefix?

  • How to conciliate OOAD and Database Design?

    - by user1620696
    Recently I've studied about object oriented analysis and design and I liked a lot about it. In every place I've read people say that the idea is to start with the minimum set of requirements and go improving along the way, revisiting this each iteration and making it better as we contiuously develop and contact the customer interested in the software. In particular, one course from Lynda.com said a lot of that: we don't want to spend a lot of time planing everything upfront, we just want to have the minimum to get started and then improve this each iteration. Now, I've also seem a course from the same guy about database design, and there he says differently. He says that although when working with object orientation he likes the agile iterative approach, for database design we should really spend a lot of time planing things upfront instead of just going along the way with the minimum. But this confuses me a little. Indeed, the database will persist important data from our domain model and perhaps configurations of the software and so on. Now, if I'm going to continuously revist the analysis and design of the model, it seems the database design should change also. In the same way, if we plan all the database upfront it seems we are also planing all the model upfront, so the two ideas seems to be incompatible. I really like agile iterative approach, but I'm also looking at getting better design for the database also, so when working with agile iterative approach, how should we deal with the database design?

  • Implementation details of database synchronisation API

    - by Daniel
    I want to achieve a database synchronisation between my server database and a client application. The server would run MySQL and the applications may run different database technologies, their implementation isn't important. I have a MySQL database online and web accessible via an API I wrote in PHP (just a detail). My client application ships with a copy of the online data. As time passes my goal is to check for any changes in the online database and make these updates available to the client app via an API call, by sending a date to an API endpoint corresponding to the last date the app was updated, the response would be a JSON filled with all new objects and updated objects, and delete IDs, this makes possible to update the local store appropriately. Essentially I want to do this: http://dbconvert.com/synchronization.php My question is about the implementation details. Would I need to add a column to my database tables with a "last modified" date? Since the client app could be very out of date if it's been offline for a long time, does that also mean I shouldn't delete data from the online database but instead have another column called "delete" set to 1 and a modified date updated appropriately? Would my SQL query simply check for all data with a modified date superior then the date passed into the API request by the client? I feel like there's a lot more to it then having a ton of dates everywhere. And also, worry that I will need to persist a lot of old data in order to ensure that old versions of the client app always have the opportunity to delete parts of their data when they are able to sync.

  • Enterprise Manager Database Control Configuration - Recovering From Errors Due to CA Expiry on Oracle Database 10.2.0.4 or 10.2.0.5 from 31-Dec-2010 onwards

    - by jayatheertha.rao(at)oracle.com
    Description What is the Issue? In Enterprise Manager Database Control with Oracle Database 10.2.0.4 and 10.2.0.5, the root certificate used to secure communications via the Secure Socket Layer (SSL) protocol will expire on 31-Dec-2010 00:00:00. The certificate expiration will cause errors if you attempt to configure Database Control on or after 31-Dec-2010. Existing Database Control configurations are not affected by this issue. Likelihood of Occurrence What Versions Are Affected? The issue impacts configuration of Database Control with Oracle Database 10.2.0.4 and 10.2.0.5 only. It does not impact database creation or upgrade. The issue does not impact existing Database Control configurations. What Happens During Database Control Configuration Failure?

  • Keyboard Shortcuts in Oracle SQL Developer

    - by thatjeffsmith
    The CTRL key, which stands for ConTRoL…aw, the good ole days What keyboard shortcuts should EVERY Oracle SQL Developer user know? How do you find new shortcuts to master, and how do you change them to match ones you’ve already learned in other tools? These are the driving questions for today’s post. While some of us may be keyboard ninjas, and others are more driven to use the mouse – everyone has probably picked up a few strategic keyboard shortcuts over the years. For example, I’ve personally JUST memorized the Cmd-Shift-4 ‘trick’ in Mac OS X. And of course we all know what F1 does, right? Right?!? Here are a few more keyboard shortcuts to commit to memory. My Favorite SQL Developer Shortcuts ctrl-enter : executes the current statement(s) F5 : executes the current code as a script (think SQL*Plus) ctrl-space : invokes code insight on demand Code Editor – Completion Insight – Enable Completion Auto-Popup (Keyword being Auto) ctrl-Up/Dn : replaces worksheet with previous/next SQL from SQL History ctrl-shift+Up/Dn : same as above but appends instead of replaces shift+F4 : opens a Describe window for current object at cursor ctrl+F7 : format SQL ctrl+/ : toggles line commenting ctrl+e : incremental search Configuring Keyboard Shortcuts in SQL Developer Tools Preferences Shortcut Keys Search by command name OR the keystroke itself Some tips… Sort by category Pay special attention to the ‘Code Editor’ and ‘Other’ categories Mind the conflicts when you change the defaults Be nice – share! You can save your new mappings with your co-workers using the Export and Import buttons Click on ‘More Actions’ to expose the Import and Export buttons When I get ‘bored’ or if I think I might be missing something, I peruse the Code Editor and Other categories, again! I’ve picked up quite a few cool editor tricks here. Then I blog about them, like they’re ‘magic.’ #EvilLaugh But the main tip is this – don’t let your previously memorized keyboard shortcuts SHORTCUT your usage of SQL Developer. If your fingers have already memorized some keystrokes, just re-program SQL Developer to match! What’s your favorite shortcut? I’ll use the most popular shortcut mentioned in the comments to round out my Top 10 list above!

  • Is it possible to make a MS-SQL Scalar function do this?

    - by Hokken
    I have a 3rd party application that can call a MS-SQL scalar function to return some summary information from a table. I was able to return the summary values with a table-valued function, but the application won't utilize table-valued functions, so I'm kind of stuck. Here's a sample from the table: trackingNumber, projTaskAward, expenditureType, amount 1122, 12345-67-89, Supplies, 100 1122, 12345-67-89, Supplies, 150 1122, 12345-67-89, Supplies, 250 1122, 12345-67-89, Misc, 50 1122, 12345-67-89, Misc, 100 1122, 98765-43-21, General, 200 1122, 98765-43-21, Conference, 500 1122, 98765-43-21, Misc, 300 1122, 98765-43-21, Misc, 100 1122, 98765-43-21, Misc, 100 I want to summarize the amounts by projTaskAward & expenditureType, based on the trackingNumber. Here is the output I'm looking for: Proj/Task/Award: 12345-67-89 Expenditure Type: Supplies Total: 500 Proj/Task/Award: 12345-67-89 Expenditure Type: Misc Total: 150 Proj/Task/Award: 98765-43-21 Expenditure Type: General Total: 200 Proj/Task/Award: 98765-43-21 Expenditure Type: Conference Total: 500 Proj/Task/Award: 98765-43-21 Expenditure Type: Misc Total: 500 I'd appreciate any help anyone can give in steering me in the right direction.

  • SQL Server 2008 Service Pack 1 and the Invoke or BeginInvoke cannot be called error message

    - by Jeff Widmer
    When trying to install SQL Server 2008 Service Pack 1 to a SQL Server 2008 instance that is running on a virtual machine, the installer will start:   But then after about 20 seconds I receive the following error message: TITLE: SQL Server Setup failure. ----------------------------- SQL Server Setup has encountered the following error: Invoke or BeginInvoke cannot be called on a control until the window handle has been created. ------------------------------ BUTTONS: OK ------------------------------ Searching for this issue I found that several people have the same problem and there is no clear solution.  Some had success with closing windows or Internet Explorer but that didn’t work for me; what did work is to make sure the SQL Server 2008 “Please wait while SQL Server 2008 Setup processes the current operation.” dialog is selected and has the focus when it first shows up.  Selected (with the current focus) it looks like this:   Without focus the dialog looks like this: Add a comment if you find out any information about how to consistently get around this issue or why it is happening in the first place.

  • Is their a definitive list for the differences between the current version of SQL Azure and SQL Serv

    - by Aim Kai
    I am a relative newbie when it comes to SQL Azure!! I was wondering if there was a definitive list somewhere regarding what is and is not supported by SQL Azure in regards to SQL Server 2008? I have had a look through google but I've noticed some of the blog posts are missing things which I have found through my own testing: For example, quite a lot is summarised in this blog entry http://www.keepitsimpleandfast.com/2009/12/main-differences-between-sql-azure-and.html Common Language Runtime (CLR) Database file placement Database mirroring Distributed queries Distributed transactions Filegroup management Global temporary tables Spatial data and indexes SQL Server configuration options SQL Server Service Broker System tables Trace Flags which is a repeat of the MSDN page http://msdn.microsoft.com/en-us/library/ff394115.aspx I've noticed from my own testing that the following seem to have issues when migrating from SQL Server 2008 to the Azure: XML Types (the msdn does mention large custom types - I guess it may include this?? even if the data schema is really small?) Multi-part views I've been using SQL Azure Migration Wizard v3.1.8 to migrate local databases into the cloud. I was wondering if anyone could point to a list or give me any information till when these features are likely to be included in SQL Azure.

  • How to rollback a database deployment without losing new data?

    - by devlife
    My company uses virtual machines for our web/app servers. This allows for very easy rollbacks of a deployment if something goes wrong. However, if an app server deployment also requires a database deployment and we have to rollback I'm kind of at a loss. How can you rollback database schema changes without losing data? The only thing that I can think of is to write a script that will drop/revert tables/columns back to their original state. Is this really the best way?

  • What resources will help me understand the fundamentals of Relational Database Systems.

    - by Rachel
    This are few of the fundamental database questions which has always given me trouble. I have tried using google and wiki but I somehow I miss out on understanding the functionality rather than terminology. If possible would really appreciate if someone can share more insights on this questions using some visual representative examples. What is a key? A candidate key? A primary key? An alternate key? A foreign key? What is an index and how does it help your database? What are the data types available and when to use which ones?

  • ASP.NET application - Error when trying to connect to a SQL Server 2008 instance

    - by Pablo Dami
    Hi everyone! Despite that I’m a regular reader of this great forum, this is my first post on it. I believe that this community can help me with the following problem that I have. I’m trying to publish an ASP.NET website over an IIS 6.0 (Windows 2003 Server), and I have some troubles trying to connect to the database. Curiously, I have installed another ASP.NET website into the same IIS 6.0 with the same properties and security parameters and can connect without problems with the same database. The application that works fine is almost the same that the one that can’t connect with SQL Server (actually is the same but with several modifications). I’ll enumarate some information related to the problem: S.O: Windows 2003 Server SQL Server Engine: SQL Server 2008 SQL Server accept remote connections? Yes. ASP.NET version: 2.0.50727 The connections via TCP/IP are enabled to the SQL Server instance? Yes. The corresponding user that I have in the connection string, actually exists into the database with the “owner” role? Yes. ORM Tool used: nHibernate I get the following error when I try to run the aplication into the browser: Error while establishing a connection to the server. When connecting to SQL Server 2005, this failure may occur because the default settings SQL Server does not allow remote connections. (provider: Shared Memory Provider, error: 40 - Could not open a connection to SQL Server) In order to isolate the problem, I made some test. For example, using the web app that works fine I can connect without any problema with the database that uses the web app that can’t. With this evidence I concluded that the problem is within the web app and not into the SQL Server instance. I also google it my problem but sadly I can't find nothing usefull to solve it. If someone can help me I’ll appreciate that. Thank you so much for your time!

  • How to get SQL Server Date in its native format?

    - by RoguePlanetoid
    I need to get a Date from an SQL Server Database (SQL Server 2000), the date is stored as such: 2009-09-30 00:00:00.000 I want to pass this date into a Classic ASP function to use this date in the Database somewhere else, however when I get the date, it converts in my ASP code to a locale-dependant version, such as: 30/09/2009 I just want the date as-is as formatting the date so it is correct again seems unnecessary, although if this the only way then fine - is there any way to treat it as string data so it stays like that, so it can be inserted back into the database as the same date, without needing conversion?

  • How can I implement a database TableView like thing in C++?

    - by Industrial-antidepressant
    How can I implement a TableView like thing in C++? I want to emulating a tiny relation database like thing in C++. I have data tables, and I want to transform it somehow, so I need a TableView like class. I want filtering, sorting, freely add and remove items and transforming (ex. view as UPPERCASE and so on). The whole thing is inside a GUI application, so datatables and views are attached to a GUI (or HTML or something). So how can I identify an item in the view? How can I signal it when the table is changed? Is there some design pattern for this? Here is a simple table, and a simple data item: #include <string> #include <boost/multi_index_container.hpp> #include <boost/multi_index/member.hpp> #include <boost/multi_index/ordered_index.hpp> #include <boost/multi_index/random_access_index.hpp> using boost::multi_index_container; using namespace boost::multi_index; struct Data { Data() {} int id; std::string name; }; struct row{}; struct id{}; struct name{}; typedef boost::multi_index_container< Data, indexed_by< random_access<tag<row> >, ordered_unique<tag<id>, member<Data, int, &Data::id> >, ordered_unique<tag<name>, member<Data, std::string, &Data::name> > > > TDataTable; class DataTable { public: typedef Data item_type; typedef TDataTable::value_type value_type; typedef TDataTable::const_reference const_reference; typedef TDataTable::index<row>::type TRowIndex; typedef TDataTable::index<id>::type TIdIndex; typedef TDataTable::index<name>::type TNameIndex; typedef TRowIndex::iterator iterator; DataTable() : row_index(rule_table.get<row>()), id_index(rule_table.get<id>()), name_index(rule_table.get<name>()), row_index_writeable(rule_table.get<row>()) { } TDataTable::const_reference operator[](TDataTable::size_type n) const { return rule_table[n]; } std::pair<iterator,bool> push_back(const value_type& x) { return row_index_writeable.push_back(x); } iterator erase(iterator position) { return row_index_writeable.erase(position); } bool replace(iterator position,const value_type& x) { return row_index_writeable.replace(position, x); } template<typename InputIterator> void rearrange(InputIterator first) { return row_index_writeable.rearrange(first); } void print_table() const; unsigned size() const { return row_index.size(); } TDataTable rule_table; const TRowIndex& row_index; const TIdIndex& id_index; const TNameIndex& name_index; private: TRowIndex& row_index_writeable; }; class DataTableView { DataTableView(const DataTable& source_table) {} // How can I implement this? // I want filtering, sorting, signaling upper GUI layer, and sorting, and ... }; int main() { Data data1; data1.id = 1; data1.name = "name1"; Data data2; data2.id = 2; data2.name = "name2"; DataTable table; table.push_back(data1); DataTable::iterator it1 = table.row_index.iterator_to(table[0]); table.erase(it1); table.push_back(data1); Data new_data(table[0]); new_data.name = "new_name"; table.replace(table.row_index.iterator_to(table[0]), new_data); for (unsigned i = 0; i < table.size(); ++i) std::cout << table[i].name << std::endl; #if 0 // using scenarios: DataTableView table_view(table); table_view.fill_from_source(); // synchronization with source table_view.remove(data_item1); // remove item from view table_view.add(data_item2); // add item from source table table_view.filter(filterfunc); // filtering table_view.sort(sortfunc); // sorting // modifying from source_able, hot to signal the table_view? // FYI: Table view is atteched to a GUI item table.erase(data); table.replace(data); #endif return 0; }

  • How do you manage your sqlserver database projects for new builds and migrations?

    - by Rory
    How do you manage your sql server database build/deploy/migrate for visual studio projects? We have a product that includes a reasonable database part (~100 tables, ~500 procs/functions/views), so we need to be able to deploy new databases of the current version as well as upgrade older databases up to the current version. Currently we maintain separate scripts for creation of new databases and migration between versions. Clearly not ideal, but how is anyone else dealing with this? This is complicated for us by having many customers who each have their own db instance, rather than say just having dev/test/live instances on our own web servers, but the processes around managing dev/test/live for others must be similar.

    If I open SSMS on my client machine, connect to our SQL server, and try and open a maintenance plan on there, I get this error: TITLE: Microsoft SQL Server Management Studio Could not load file or assembly 'msddsp, Version=9.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.

  • SQL Server installation leaves odd hotfix folders on the root

    - by Nick
    I have about a dozen weirdly named folders, for example 5e812807b3e1b04248ed046794a01b, on my d: drive after installing SQL Server 2008. Inside each folder are two subfolders: 1033 and hotfixexpress \1033\eula.txt \1033\finalsql2005information.rtf \1033\hotfix.rll \1033\sqlhotfix.chm \1033\sqlse.rll \hotfixexpress\files\sqlexpr.exe I get access denied whenever I try to delete any of these files / folders. I tried again after stopping all SQL server services, without luck. Any ideas?

  • What is "The" book for database design?

    - by FarmBoy
    In programming, there is often a canonical book for a particular topic, like the dragon book for compilers, K&R for C, etc. Is their a book regarding modern database design that simply must be read by anyone that would hope to eventually design databases? I'm not looking for a bunch of recommendations here. The answer I'm looking for is either "Yes, it's [Title, author]." or "No, there are many good books on databases, but no one must-read."

  • SQL Server 2008 - "Enhanced read-ahead and scan"?

    - by Chris J
    Hi all, Can anyone point me to, or does anyone know what this "feature" of SQL Server is? Googling for it (also for "Super scan" which seems to be a synonym for the feature) reveals no information other than all the edition comparison pages that exist out there for SQL Server. I'm also not sure whether this is a stackoverflow or a serverfault question. I'll try here on serverfault first, but if folk think stackoverflow may be a better forum, drop me a comment to that effect - ta :-)

  • Don't see job schedule added by sp_add_jobschedule in SQL Mgmt UI

    - by Ariel
    I'm running a script like below on a SQL Server box and, even though it finishes correctly, then when, on SQL Mgmt UI, I right click on that job's properties, go to Schedules, I cannot see the schedule just added... what am I missing? (I'm using the right job_name param, etc) thanks! BEGIN TRY BEGIN TRAN EXEC msdb.dbo.sp_add_jobschedule @job_name = 'Job name', @name=N'Job schedule name', @enabled = 0, @freq_type=1, @active_start_date=20100525, @active_start_time=60000 COMMIT TRAN END TRY BEGIN CATCH SELECT ERROR_Message(), ERROR_Line(); ROLLBACK TRAN END CATCH
