• Copying files from one machine to another

  - by arex1337

  I'm currently generating documentation on one machine, and publishing it to a web server using the following commands in a script: net use "\\someShare" PASSWORD /user:username del /S /Q "\\someShare" xcopy /E /Y Documentation\html\* "\\someShare\" However, it feels like a really bad idea to have a password as plain text in the script, so I'm looking for alternatives to my current solution. Ideas? I definitely would appreciate a solution that uses some kind of access control, as many different people should be allowed to publish their own documentation to the web server, but not mess with each other's docs.

• SQLAuthority News – Statistics Used by the Query Optimizer in Microsoft SQL Server 2008 – Microsoft Whitepaper

  - by pinaldave

  I recently presented session on Statistics and Best Practices in Virtual Tech Days on Nov 22, 2010. The sessions was very popular and I got many questions right after the sessions. The number question I had received was where everybody can get the further information. I am very much happy that my sessions created some curiosity for one of the most important feature of the SQL Server. Statistics are the heart of the SQL Server. Microsoft has published a white paper on the subject how statistics are useful to Query Optimizer. Here is the abstract of the same white paper from Microsoft. Statistics Used by the Query Optimizer in Microsoft SQL Server 2008 Writer: Eric N. Hanson and Yavor Angelov Microsoft SQL Server 2008 collects statistical information about indexes and column data stored in the database. These statistics are used by the SQL Server query optimizer to choose the most efficient plan for retrieving or updating data. This paper describes what data is collected, where it is stored, and which commands create, update, and delete statistics. By default, SQL Server 2008 also creates and updates statistics automatically, when such an operation is considered to be useful. This paper also outlines how these defaults can be changed on different levels (column, table, and database). In addition, it presents how certain query language features, such as Transact-SQL variables, interact with use of statistics by the optimizer, and it provides guidance for using these features when writing queries so you can obtain good query performance.

• SQL SERVER – What is AdventureWorks?

  - by pinaldave

  NOTE: If you know the answer of this question, then I request you to stop reading this post right now. Please do not leave comment about this blog post not being useful to you, if you knew the answer. Few days ago, I received DM asking What is an AdventureWorks database and why in all the examples I use that instead of any other database (e.g. Pubs or  Northwind)? As matter of fact, when I went back to my question list, which I have yet not answered, there were a few more variations of this same question. AdventureWorks is a Sample Database shipped with SQL Server and it can be downloaded from http://codeplex.com site. AdventureWorks has replaced Northwind and Pubs from the sample database in SQL Server 2005. The Microsoft team keeps updating the sample database as they release new versions. Here are some quick links: AdventureWorks SQL Server 2008 SR4 AdventureWorks 2008R2 November CTP AdventureWorks for SQL Azure (December CTP) AventureWorks for SQL Server 2005 SP2A SQL SERVER – 2008 – Download and Install Samples Database AdventureWorks 2005 – Detail Tutorial I have previously written few other articles on the same subject; you can find them easily here: [email protected] Reference: Pinal Dave (http://blog.SQLAuthority.com) Filed under: Pinal Dave, SQL, SQL Authority, SQL Documentation, SQL Download, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• SQL SERVER – Difference Between ROLLBACK IMMEDIATE and WITH NO_WAIT during ALTER DATABASE

  - by pinaldave

  Today, we are going to discuss about something very simple, but quite commonly confused two options of ALTER DATABASE. The first one is ALTER DATABASE …ROLLBACK IMMEDIATE and the second one is WITH NO_WAIT. Many people think they are the same or are not sure of the difference between these two options. Before we continue our explaination, let us go through the explanation given by Book On Line. ROLLBACK AFTER integer [SECONDS] | ROLLBACK IMMEDIATE Specifies whether to roll back after a specified number of seconds or immediately. NO_WAIT Specifies that if the requested database state or option change cannot complete immediately without waiting for transactions to commit or roll back on their own, then the request will fail. If you have understood the difference by now, there is no need to proceed further. If you are still confused, continue with the rest of the post. There is one big difference between ROLLBACK and NO_WAIT. In case incomplete Transaction ALTER DATABASE … ROLLBACK rollbacks those incomplete transaction immediately, where as ALTER DATABASE … NO_WAIT will terminate and rollback the transaction of ALTER DATABASE … NO_WAIT itself. I think it can be clearly explained with the help of the following images. Option 1: ALTER DATABASE … ROLLBACK Connection 1 – Simulating some operation using WAITFOR DELAY WAITFOR DELAY '1:00:00' Connection 2 ALTER DATABASE TestDb SET SINGLE_USER WITH ROLLBACK IMMEDIATE; Option 2: ALTER DATABASE … NO_WAIT Connection 1 – Simulating some operation using WAITFOR DELAY WAITFOR DELAY '1:00:00' Connection 2 ALTER DATABASE TestDb SET SINGLE_USER WITH NO_WAIT; Let me know if this example was simple enough.

• SQLAuthority News – Bookmark – Deprecated Database Engine Features in SQL Server 2008

  - by pinaldave

  When anybody asked me if any specific feature is available in SQL Server 2008 or if any feature will be disabled in future versions of SQL Server, I always point everybody to following list where all the deprecated database engine features are listed. Deprecated Database Engine Features in SQL Server 2008 R2 Deprecated Database Engine Features in SQL Server 2008 This list is quite helpful and everybody should refer it once. This list has many important details. For example, it suggests “80 compatibility level and upgrade from version 80.” will not be supported in next version of SQL Server. If you are using SQL Server 2000 still today (by any chance) you will be not able to upgrade that to next version of SQL Server directly. It is very important to note that if you are using any feature of SQL Server in compatibility mode and if you find them in the list above. You need to start working on the replacement suggested in article.

• SQL SERVER – Migration Assistant Upgraded to Support SQL Server 2014

  - by Pinal Dave

  We all start somewhere when it is about database. There are different reasons, why we go for one database over another database. Usually the reason is cost and convenience. After a period of time when business is successful and traffic is growing, the same two reasons of cost and convenience start to become secondary goals. I have seen quite a lot of companies starting with free databases and after a while switching to another database as they want stability and service from the product company. Microsoft has an excellent product which lets you migrate your database from the alternate database to SQL Server. It is called SQL Server Migration Assistant (SSMA) and earlier this week, it has been upgraded to support SQL Server 2014. Now you can migrate from your database to to all editions of SQL Server 2005, SQL Server 2008, SQL Server 2008 R2, SQL Server 2012 and SQL Server 2014. SQL Server Migration Assistant (SSMA) is a free supported tool from Microsoft. Here is where you can download SSMA v5.3 for various databases.

• SQLAuthority News – 2 Whitepapers Announced – AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution

  - by pinaldave

  Understanding AlwaysOn Architecture is extremely important when building a solution with failover clusters and availability groups. Microsoft has just released two very important white papers related to this subject. Both the white papers are written by top experts in industry and have been reviewed by excellent panel of experts. Every time I talk with various organizations who are adopting the SQL Server 2012 they are always excited with the concept of the new feature AlwaysOn. One of the requests I often here is the related to detailed documentations which can help enterprises to build a robust high availability and disaster recovery solution. I believe following two white paper now satisfies the request. AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution by Using AlwaysOn Availability Groups SQL Server 2012 AlwaysOn Availability Groups provides a unified high availability and disaster recovery (HADR) solution. This paper details the key topology requirements of this specific design pattern on important concepts like quorum configuration considerations, steps required to build the environment, and a workflow that shows how to handle a disaster recovery. AlwaysOn Architecture Guide: Building a High Availability and Disaster Recovery Solution by Using Failover Cluster Instances and Availability Groups SQL Server 2012 AlwaysOn Failover Cluster Instances (FCI) and AlwaysOn Availability Groups provide a comprehensive high availability and disaster recovery solution. This paper details the key topology requirements of this specific design pattern on important concepts like asymmetric storage considerations, quorum model selection, quorum votes, steps required to build the environment, and a workflow. If you are not going to implement AlwaysOn feature, this two Whitepapers are still a great reference material to review as it will give you complete idea regarding what it takes to implement AlwaysOn architecture and what kind of efforts needed. One should at least bookmark above two white papers for future reference.

• SQLAuthority News – Scaling Up Your Data Warehouse with SQL Server 2008 R2

  - by pinaldave

  Data Warehouses are suppose to be containing huge amount of the data from the beginning. However, there are cases when too big is not enough. Every Data Warehouse Admin will agree that they have faced situation where they will need to scale up their data warehouse. Microsoft has released white paper discussing the same. Here is the abstract from the Microsoft Official site: SQL Server 2008 introduced many new functional and performance improvements for data warehousing, and SQL Server 2008 R2 includes all these and more. This paper discusses how to use SQL Server 2008 R2 to get great performance as your data warehouse scales up. We present lessons learned during extensive internal data warehouse testing on a 64-core HP Integrity Superdome during the development of the SQL Server 2008 release, and via production experience with large-scale SQL Server customers. Our testing indicates that many customers can expect their performance to nearly double on the same hardware they are currently using, merely by upgrading to SQL Server 2008 R2 from SQL Server 2005 or earlier, and compressing their fact tables. We cover techniques to improve manageability and performance at high-scale, encompassing data loading (extract, transform, load), query processing, partitioning, index maintenance, indexed view (aggregate) management, and backup and restore.

• SQLAuthority News – Whitepaper Download – Using Star Join and Few-Outer-Row Optimizations to Improve Data Warehousing Queries

  - by pinaldave

  Size of the database is growing every day. Many organizations now a days have more than TB of the Data in their system. Performance is always part of the issue. Microsoft is really paying attention to the same and also focusing on improving performance for Data Warehousing. Microsoft has recently released whitepaper on the performance tuning subject of Data Warehousing. Here is the abstract about the whitepaper from official site: In this white paper we discuss two of the new features introduced in SQL Server 2008, Star Join and Few-Outer-Row optimizations. These two features are in SQL Server 2008 R2 as well.  We test the performance of SQL Server 2008 on a set of complex data warehouse queries designed to highlight the effect of these two features and observed a significant performance gain over SQL Server 2005 (without these two features). The results observed also apply to SQL Server 2008 R2.  On average, about 75 percent of the query execution time has been reduced, compared to SQL Server 2005. We also include data that shows a reduction in the number of rows processed and improved balance in parallel queries, both of which highlight the important role the Star Join and Few Outer-Row features played. I encouraged all of those interested in Data Warehouse to read it and see if they can learn the tricks.

• Tender vs. Requirements vs. Solution Design

  - by Tom Tom

  Conventionally, which of the above documents is deemed to hold the most weight when it comes to system acceptance? I recently had a conversation along these lines: It was argued that the initial requirements / tender documentation should be used to determine system acceptance. It was said that the solution design only serves to describe the way in which the system will solve the problem, not the problem it will solve. Furthermore, it was argued that if requirements are missed during solution design, the requirements should be referenced during system acceptance and that if any requirements were missed then the original tender should be referenced. Conversely, I suggested that - while requirements may be based on the original tender - they supersede it once agreed with the stakeholders. Furthermore, during solution design, analysis is performed to address and refine these initial requirements, translating them into a system capable of meeting the actual requirements. Once signed off by the relevant users, this solution design should absolutely represent the requirements (by virtue of the fact that it's designed upon them) but actually supersedes them as the basis for system acceptance. Is one of the above arguments more valid than the other?

• Modelling work-flow plus interaction with a database - quick and accessible options

  - by cjmUK

  I'm wanting to model a (proposed) manufacturing line, with specific emphasis on interaction with a traceability database. That is, various process engineers have already mapped the manufacturing process - I'm only interested in the various stations along the line that have to talk to the DB. The intended audience is a mixture of project managers, engineers and IT people - the purpose is to identify: points at which the line interacts with the DB (perhaps going so far as indicating the Store Procs called at each point, perhaps even which parameters are passed.) the communication source (PC/Handheld device/PLC) the communication medium (wireless/fibre/copper) control flow (if leak test fails, unit is diverted to repair station) Basically, the model will be used as a focus different groups on outstanding tasks; for example, I'm interested in the DB and any front-end app needed, process engineers need to be thinking about the workflow and liaising with the PLC suppliers, the other IT guys need to make sure we have the hardware and comms in place. Obviously I could just improvise in Visio, but I was wondering if there was a particular modelling technique that might particularly suit my needs or my audience. I'm thinking of a visual model with supporting documentation (as little as possible, as much as is necessary). Clearly, I don't want something that will take me ages to (effectively) learn, nor one that will alienate non-technical members of the project team. So far I've had brief looks at BPMN, EPC Diagrams, standard Flow Diagrams... and I've forgotten most of what I used to know about UML... And I'm not against picking and mixing... as long as it is quick, clear and effective. Conclusion: In the end, I opted for a quasi-workflow/dataflow diagram. I mapped out the parts of the manufacturing process that interact with the traceability DB, and indicated in a significantly-simplified form, the data flows and DB activity. Alongside which, I have a supporting document which outlines each process, the data being transacted for each process (a 'data dictionary' of sorts) and details of hardware and connectivity required. I can't decide whether is a product of genius or a crime against established software development practices, but I do think that is will hit the mark for this particular audience.

• How to generate a metamodel for POJOs

  - by Stefan Haberl

  I'm looking for a metamodel generation library for simple Java POJOs. I'm thinking about something along the lines of JPA 2.0's metamodel, which can be used to generate type safe criterias for JPA entities (see this Question on SO for JPA specific implementations). Does something similar exist for general purpose JavaBeans, i.e., POJOS, that are not JPA entities? Specifically, I want to implement Spring MVC's WebDataBinder.setAllowedFields() method in a type safe way in my Spring MVC @Controllers

• Procedurally generated 2d terrain for side scroller on Sega Genesis hardware?

  - by DJCouchyCouch

  I'm working on the Sega Genesis that has a 8mhz Motorola 68000 CPU. Any ideas on how to generate fast and decent 2d tile terrain for a side scroller in real time? The game would generate new columns or rows depending on the direction the player is scrolling in. The generation would have to be deterministic. The same seed value would generate the same terrain. I'm looking for algorithms that would satisfy the memory and CPU constraints of the hardware.

• SQL SERVER – Developer Training Kit for SQL Server 2012

  - by pinaldave

  Developer Training Kit is my favorite part of any product. The reason behind is very simple because it give the single resource which gives complete overview of the product in nutshell. A developer can learn from many places – books, webcasts, tutorials, blogs, etc. However, I have found that developer training kits are the best starting point for any product. Start with them first, see what are the new features as well what is the new message a product is coming up with. Once it is learned the very next step should be to identify the right learning material to explore the preferred topic. The SQL Server 2012 Developer Training Kit includes technical content including labs, demos and presentations designed to help you learn how to develop SQL Server 2012 database and BI solutions. New and updated content will be released periodically and can be downloaded on-demand using the Web Installer. Download SQL Server 2012 Developer Training Kit Web Installer. This training kit was available earlier this year but it is never late to explore it if you have not referred it earlier. Additionally, if you do not want to download complete kit all together I suggest you refer to Wiki here. This wiki contains all the same presentations and demo notes which web installer contains. Refer to SQL Server 2012 Developer Training Kit Wiki Wiki contains following module and details about Hands On Labs Module 1: Introduction to SQL Server 2012 Module 2: Introduction to SQL Server 2012 AlwaysOn Module 3: Exploring and Managing SQL Server 2012 Database Engine Improvements Module 4: SQL Server 2012 Database Server Programmability Module 5: SQL Server 2012 Application Development Module 6: SQL Server 2012 Enterprise Information Management Module 7: SQL Server 2012 Business Intelligence Hands-On Labs: SQL Server 2012 Database Engine Hands-On Labs: Visual Studio 2010 and .NET 4.0 Hands-On Labs: SQL Server 2012 Enterprise Information Management Hands-On Labs: SQL Server 2012 Business Intelligence Hands-On LabsHands-On Labs: Windows Azure and SQL Azure As I said, if you have not downloaded this so far, it is never late to explore it. Trust me you will atleast learn one thing if you just explore the content.
