• iOS Support with Windows Azure Mobile Services – now with Push Notifications

  - by ScottGu

  A few weeks ago I posted about a number of improvements to Windows Azure Mobile Services. One of these was the addition of an Objective-C client SDK that allows iOS developers to easily use Mobile Services for data and authentication.  Today I'm excited to announce a number of improvement to our iOS SDK and, most significantly, our new support for Push Notifications via APNS (Apple Push Notification Services).  This makes it incredibly easy to fire push notifications to your iOS users from Windows Azure Mobile Service scripts. Push Notifications via APNS We've provided two complete tutorials that take you step-by-step through the provisioning and setup process to enable your Windows Azure Mobile Service application with APNS (Apple Push Notification Services), including all of the steps required to configure your application for push in the Apple iOS provisioning portal: Getting started with Push Notifications - iOS Push notifications to users by using Mobile Services - iOS Once you've configured your application in the Apple iOS provisioning portal and uploaded the APNS push certificate to the Apple provisioning portal, it's just a matter of uploading your APNS push certificate to Mobile Services using the Windows Azure admin portal: Clicking the “upload” within the “Push” tab of your Mobile Service allows you to browse your local file-system and locate/upload your exported certificate.  As part of this you can also select whether you want to use the sandbox (dev) or production (prod) Apple service: Now, the code to send a push notification to your clients from within a Windows Azure Mobile Service is as easy as the code below: push.apns.send(deviceToken, {      alert: 'Toast: A new Mobile Services task.',      sound: 'default' }); This will cause Windows Azure Mobile Services to connect to APNS (Apple Push Notification Service) and send a notification to the iOS device you specified via the deviceToken: Check out our reference documentation for full details on how to use the new Windows Azure Mobile Services apns object to send your push notifications. Feedback Scripts An important part of working with any PNS (Push Notification Service) is handling feedback for expired device tokens and channels. This typically happens when your application is uninstalled from a particular device and can no longer receive your notifications. With Windows Notification Services you get an instant response from the HTTP server.  Apple’s Notification Services works in a slightly different way and provides an additional endpoint you can connect to poll for a list of expired tokens. As with all of the capabilities we integrate with Mobile Services, our goal is to allow developers to focus more on building their app and less on building infrastructure to support their ideas. Therefore we knew we had to provide a simple way for developers to integrate feedback from APNS on a regular basis.  This week’s update now includes a new screen in the portal that allows you to optionally provide a script to process your APNS feedback – and it will be executed by Mobile Services on an ongoing basis: This script is invoked periodically while your service is active. To poll the feedback endpoint you can simply call the apns object's getFeedback method from within this script: push.apns.getFeedback({       success: function(results) {           // results is an array of objects with a deviceToken and time properties      } }); This returns you a list of invalid tokens that can now be removed from your database. iOS Client SDK improvements Over the last month we've continued to work with a number of iOS advisors to make improvements to our Objective-C SDK. The SDK is being developed under an open source license (Apache 2.0) and is available on github. Many of the improvements are behind the scenes to improve performance and memory usage. However, one of the biggest improvements to our iOS Client API is the addition of an even easier login method.  Below is the Objective-C code you can now write to invoke it: [client loginWithProvider:@"twitter"                     onController:self                        animated:YES                      completion:^(MSUser *user, NSError *error) {      // if no error, you are now logged in via twitter }]; This code will automatically present and dismiss our login view controller as a modal dialog on the specified controller.  This does all the hard work for you and makes login via Twitter, Google, Facebook and Microsoft Account identities just a single line of code. My colleague Josh just posted a short video demonstrating these new features which I'd recommend checking out: Summary The above features are all now live in production and are available to use immediately.  If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using Mobile Services today. Visit the Windows Azure Mobile Developer Center to learn more about how to build apps with Mobile Services. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

• How to Track Number of Changes Occured in a Column? T-SQL - SQL Server

  - by user327387

  For example, i have a column named EmployeeName. Every time a user changes/fix his name, i need to keep a count. If he changes his name twice, then count is 2. Also, i need to store the time of every change employee makes on EmployeeName e.g. if the name essentially is James and time created is 9:00 AM and then employee changes to John on 11:00 AM, i need to preserve this new time and new value as well as the previous one which is James at 9:00 AM. I hope its clear! Thank you guys...Best Answer will be chosen... If this requires a trigger, giving a sketchy pseudo-code will be very much appreciated.

• The SQL Server Setup Portal

  - by BuckWoody

  One of the tasks that takes a long time for the data professional is setting up SQL Server. No, it isn’t that difficult to slide a DVD in a drive and click “Setup” but the overall process of planning the hardware and software environment, making decisions for high-availability, security and dozens of other choices can make the process more difficult. And then, of course, there are the inevitable issues that arise. Microsoft supports literally hundreds and even thousands of combinations of hardware and software drivers from vendors you’ve never even heard of. Making all of that work together is a small miracle, so things are bound to arise that you need to deal with. So, to help you out, we’ve designed a new “SQL Server Setup Portal”. It’s a one-stop-shop for everything you need to know about planning and setting up SQL Server. As time goes on you’ll see even more content added. There are already whitepapers, videos, and multiple places to search on everything from topic names to error codes. So go check it out – and if you have to do a lot of SQL Server Setups – and especially if you don’t – bookmark it as a favorite!

• How would I design this table in SQL?

  - by RSharma

  I have a parent master table that is generic enough to hold the common information of the children. Since the children were substantially different, we created separate tables for them. So I have something like this: tblMaster -------- MasterID int Name varchar(50) --Common to all children and there are a bunch of fields like this ChildType int -- Type of Child either ChildOne or ChildTwo ChildID int -- need to store ChildOneID or ChildTwoID depending on type of Child, so that i can refer to children tblChild1 -------- ChildOneID int IDENTITY tblChild2 --------- ChildTwoID int IDENTITY Should I have a ChildID in the master that is either ChildOneID or ChildTwoID based on the ChildType column? I have a number of children and I have simplified it for this question. The other way is to add ChildOneID and ChildTwoID as columns in the master, but since i have a number of columns, I will have a lot of null columns EDIT: Any help is appreciated

• Cloud – the forecast is improving

  - by Rob Farley

  There is a lot of discussion about “the cloud”, and how that affects people’s data stories. Today the discussion enters the realm of T-SQL Tuesday, hosted this month by Jorge Segarra. Over the years, companies have invested a lot in making sure that their data is good, and I mean every aspect of it – the quality of it, the security of it, the performance of it, and more. Experts such as those of us at LobsterPot Solutions have helped these companies with this, and continue to work with clients to make sure that data is a strong part of their business, not an oversight. Whether business intelligence systems are being utilised or not, every business needs to be able to rely on its data, and have the confidence in it. Data should be a foundation upon which a business is built. In the past, data had been stored in paper-based systems. Filing cabinets stored vital information. Today, people have server rooms with storage of various kinds, recognising that filing cabinets don’t necessarily scale particularly well. It’s easy to ‘lose’ data in a filing cabinet, when you have people who need to make sure that the sheets of paper are in the right spot, and that you know how things are stored. Databases help solve that problem, but still the idea of a large filing cabinet continues, it just doesn’t involve paper. If something happens to the physical ‘filing cabinet’, then the problems are larger still. Then the data itself is under threat. Many clients have generators in case the power goes out, redundant cables in case the connectivity dies, and spare servers in other buildings just in case they’re required. But still they’re maintaining filing cabinets. You see, people like filing cabinets. There’s something to be said for having your data ‘close’. Even if the data is not in readable form, living as bits on a disk somewhere, the idea that its home is ‘in the building’ is comforting to many people. They simply don’t want to move their data anywhere else. The cloud offers an alternative to this, and the human element is an obstacle. By leveraging the cloud, companies can have someone else look after their filing cabinet. A lot of people really don’t like the idea of this, partly because the administrators of the data, those people who could potentially log in with escalated rights and see more than they should be allowed to, who need to be trusted to respond if there’s a problem, are now a faceless entity in the cloud. But this doesn’t mean that the cloud is bad – this is simply a concern that some people may have. In new functionality that’s on its way, we see other hybrid mechanisms that mean that people can leverage parts of the cloud with less fear. Companies can use cloud storage to hold their backup data, for example, backups that have been encrypted and are therefore not able to be read by anyone (including administrators) who don’t have the right password. Companies can have a database instance that runs locally, but which has its data files in the cloud, complete with Transparent Data Encryption if needed. There can be a higher level of control, making the change easier to accept. Hybrid options allow people who have had fears (potentially very justifiable) to take a new look at the cloud, and to start embracing some of the benefits of the cloud (such as letting someone else take care of storage, high availability, and more) without losing the feeling of the data being close. @rob_farley

• Move database from SQL Server 2012 to 2008

  - by Rich

  I have a database on a SQL Sever 2012 instance which I would like to copy to a 2008 server. The 2008 server cannot restore backups created by a 2012 server (I have tried). I cannot find any options in 2012 to create a 2008 compatible backup. Am I missing something? Is there an easy way to export the schema and data to a version-agnostic format which I can then import into 2008? The database does not use any 2012 specific features. It contains tables, data and stored procedures. Here is what I have tried so far: I tried "tasks" - "generate scripts" on the 2012 server, and I was able to generate the schema (including stored procedures) as a sql script. This didn't include any of the data, though. After creating that schema on my 2008 machine, I was able to open the "Export Data" wizard on the 2012 machine, and after configuring the 2012 as source machine and the 2008 as target machine, I was presented with a list of tables which I could copy. I selected all my tables (300+), and clicked through the wizard. Unfortunately it spends ages generating its scripts, then fails with errors like "Failure inserting into the read-only column 'FOO_ID'". I also tried the "Copy Database Wizard", which claimed to be able to copy "from 2000 or later to 2005 or later". It has two modes: 1) "detach and attach", which failed with error: Message: Index was outside the bounds of the array. StackTrace: at Microsoft.SqlServer.Management.Smo.PropertyBag.SetValue(Int32 index, Object value) ... at Microsoft.SqlServer.Management.Smo.DataFile.get_FileName() 2) SQL Management Object Method which failed with error "Cannot read property IsFileStream.This property is not available on SQL Server 7.0."

• How do I add a self-referencing linked server in SQL 2008

  - by tigermain

  I am trying to replicate our live server set up local using a single SQL database. In SQL 2005 I would added 2 linked servers both referencing itself with different names, each point to a different table. How do I do this in SQL 2008. I've try the various providers and different parameters butto no avail. The local server is using a trusted connection so I dont need any usernames/passwords Im ideally need to set up the following linked references: DBSVR1 - mydb_master DBSVR2 - mydb_import Any light on the subject would help, I managed to do it in 2005 about 8 months ago but cant remember how, now Im in 2008!

• SQL Server 2005, Sudden increase of connections - SharePoint 2007

  - by CrazyNick

  We observed that sudden increase of SQL connections during a specific hour, it is a backend of a SharePoint 2007 Farm. From SharePoint 2007 Perspective: 1. Incremental crawling is scheduled at that time and few of the Timer jobs (normal timer jobs) are scheduled to run every mins / per 10mins. 2. Number of user requests are less. From SQL Server 2005 Perspective: 1. Transaction log backup is scheduled at that time 2. No other scheduled jobs are running at that time. so, how to narrow down the issue, what would be causing the sudden SQL connection increase?

• Sql Server 2005 cluster - unable to rename to old server name

  - by Paul2020

  We have a sql 2005 cluster on W2K8 cluster. It is a named instance say SRV1\A. Then I built a new W2K8 (with a diff cluster service name) but the same service account. Then I installed a new sql 2005 cluster say SRV2\A. Now when I bring down the sql server resources on SRV1 and try to rename SRV2\A to SRV1\A through the cluster admin, I get the error the network name already exists. I have tried bringing an old cluster and installing a new cluster with the same name and it works. Why am I not able to rename the name? Any advice would very helpful.

• Windows Azure Virtual Machines - Make Sure You Follow the Documentation

  - by BuckWoody

  To create a Windows Azure Infrastructure-as-a-Service Virtual Machine you have several options. You can simply select an image from a “Gallery” which includes Windows or Linux operating systems, or even a Windows Server with pre-installed software like SQL Server. One of the advantages to Windows Azure Virtual Machines is that it is stored in a standard Hyper-V format – with the base hard-disk as a VHD. That means you can move a Virtual Machine from on-premises to Windows Azure, and then move it back again. You can even use a simple series of PowerShell scripts to do the move, or automate it with other methods. And this then leads to another very interesting option for deploying systems: you can create a server VHD, configure it with the software you want, and then run the “SYSPREP” process on it. SYSPREP is a Windows utility that essentially strips the identity from a system, and when you re-start that system it asks a few details on what you want to call it and so on. By doing this, you can essentially create your own gallery of systems, either for testing, development servers, demo systems and more. You can learn more about how to do that here: http://msdn.microsoft.com/en-us/library/windowsazure/gg465407.aspx   But there is a small issue you can run into that I wanted to make you aware of. Whenever you deploy a system to Windows Azure Virtual Machines, you must meet certain password complexity requirements. However, when you build the machine locally and SYSPREP it, you might not choose a strong password for the account you use to Remote Desktop to the machine. In that case, you might not be able to reach the system after you deploy it. Once again, the key here is reading through the instructions before you start. Check out the link I showed above, and this link: http://technet.microsoft.com/en-us/library/cc264456.aspx to make sure you understand what you want to deploy.

• An XEvent a Day (19 of 31) – Using Customizable Fields

  - by Jonathan Kehayias

  Today’s post will be somewhat short, but we’ll look at Customizable Fields on Events in Extended Events and how they are used to collect additional information.  Customizable Fields generally represent information of potential interest that may be expensive to collect, and is therefore made available for collection if specified by the Event Session.  In SQL Server 2008 and 2008 R2, there are 50 Events that have customizable columns in their payload.  In SQL Server Denali CTP1, there...(read more)

• An XEvent a Day (1 of 31) – An Overview of Extended Events

  - by Jonathan Kehayias

  First introduced in SQL Server 2008, Extended Events provided a new mechanism for capturing information about events inside the Database Engine that was both highly performant and highly configurable. Designed from the ground up with performance as a primary focus, Extended Events may seem a bit odd at first look, especially when you compare it to SQL Trace. However, as you begin to work with Extended Events, you will most likely change how you think about tracing problems, and will find the power...(read more)

• Is SQL Server 2008 R2 a full release of SQL Server?

  - by AaronBertrand

  This has come up in conversations more than once in the past little while - recently on twitter I made the casual comment that later this year, SQL Server 2008 will be "two versions old." Well, not everyone agrees that that is technically true. So, I thought I'd put something out there that isn't limited to 140 characters. There are certainly some valid arguments on both sides, but my opinion - based both on these facts and on my memory that Microsoft has marketed it as such - is that SQL Server...(read more)

• MSBuild / PowerShell: Copy SQL Server 2012 database to SQL Azure via BACPAC (for Continuous Integration)

  - by giveme5minutes

  I'm creating a continuous integration MSBuild script which copies a database in on-premise SQL Server 2012 to SQL Azure. Easy right? Methods After a fair bit of research I've come across the following methods: Use PowerShell to access the DAC library directly, then use the MSBuild PowerShell extension to wrap the script. This would require installing PowerShell 3 and working out how to make the MSBuild PowerShell extension work with it, as apparently MS moved the DAC API to a different namespace in the latest version of the library. PowerShell would give direct access to the API, but may require quite a bit of boilerplate. Use the sample DAC Framework Client Side Tools, which requires compiling them myself, as the downloads available from Codeplex only include the Hosted version. It would also require fixing them to use DAC 3.0 classes as they appear to currently use an earlier version of DAC. I could then call these tools from an <Exec Command="" /> in the MSBuild script. Less boilerplate and if I hit any bumps in the road I can just make changes to the source. Processes Using whichever method, the process could be either: Export from on-premise SQL Server 2012 to local BACPAC Upload BACPAC to blog storage Import BACPAC to SQL Azure via Hosted DAC Or: Export from on-premise SQL Server 2012 to local BACPAC Import BACPAC to SQL Azure via Client DAC Question All of the above seems to be quite a lot of effort for something that seems to be a standard feature... so before I start reinventing the wheel and documenting the results for all to see, is there something really obvious that I've missed here? Is there pre-written script that MS has released that I have not yet uncovered? There's an command in the GUI of SQL Server Management Studio 2012 that does EXACTLY what I'm trying to do (right click on local database, click "Tasks", click "Deploy Database to SQL Azure"). Surely if it's a few clicks in the GUI it must be a single command on the command line somewhere??
