• SQL Server 2008 R2: StreamInsight changes at RTM: AdvanceTimeSettings

  - by Greg Low

  For those that have worked with the earlier versions of the simulator that Bill Chesnut and I constructed for the Metro content (the Highway Simulator), changes are also required to how AdvanceTimeSettings are specified. The AdapterAdvanceTimeSettings value is now generated by binding an AdvanceTimeGenerationSettings (that is based on your adapter configuration) with an AdvanceTimePolicy setting. public class TollPointInputFactory : ITypedInputAdapterFactory < TollPointInputConfig >, ITypedDeclareAdvanceTimeProperties...(read more)

• Preventing Netbeans JAXB generation trashing classes

  - by Mac

  I'm developing a SOAP service using JAX-WS and JAXB under Netbeans 6.8, and getting a little frustrated with Netbeans trashing my work every time the XSD schema my JAXB bindings are based upon changes. To elaborate, the IDE automatically generates classes bound to the schema, which can then be (un)marshalled from/to XML using JAXB. To these classes I've added extra methods to (for example) convert to and from separate classes designed to be persisted to database with JPA. The problem is that whenever the schema changes and I rebuild, these classes are regenerated, and all my custom methods are deleted. I can manually replace them by copy-pasting from a backup file, but that is rather time-consuming and tedious. As I'm using an iterative design approach, the schema is changing rather frequently and I'm wasting an awful lot of time whenever it does, simply to reinstate my previous code. While the IDE automatically regenerating the JAXB-bound classes is entirely reasonable and I don't mean to imply otherwise, I was wondering if anyone had any bright ideas as to how to prevent my extra work having to be manually reinstated every time my schema changes?

• Cost-effective .Net solutions for report generation in Excel and PDF

  - by jamesaharvey

  I'm looking for some cost-effective solutions and/or open source options for generating reports in Excel and PDF format. I realize some of the open source options may have less in terms of functionality and flexibility than the COTS versions with all the bells and whistles, but are there any options out there that fall somewhere in between? EDIT: Essentially what I'll have are just some basic HTML reports of data in tables with some calculations/summary data but nothing fancy like graphs, etc. I'll then need the ability to export these HTML reports to Excel and/or PDF.

• C: Random Number Generation - What (If Anything) Is Wrong With This

  - by raoulcousins

  For a simple simulation in C, I need to generate exponential random variables. I remember reading somewhere (but I can't find it now, and I don't remember why) that using the rand() function to generate random integers in a fixed range would generate non-uniformly distributed integers. Because of this, I'm wondering if this code might have a similar problem: //generate u ~ U[0,1] u = ( (double)rand() / ((double)(RAND_MAX)); //inverse of exponential CDF to get exponential random variable expon = -log(1-u) * mean; Thank you!

• SELECT TOP 1

  - by Derek Dieter

  There are many good uses of the SELECT TOP 1 method of querying. Essentially, the select top 1 method is used to find the min or max record for a particular value. There is some debate as to whether this is the ‘correct’ method of querying, however it should be known that this [...]

• How In-Memory Database Objects Affect Database Design: Hybrid Code

  - by drsql

  In my first attempts at building my code, I strictly went with either native or on-disk code. I specifically wrote the on-disk code to only use features that worked in-memory. This lead to one majorly silly bit of code, used to create system assigned key values. How would I create a customer number that was unique. We can’t use the Max(value) + 1 approach because it will be very hideous with MVCC isolation levels, since 100 connections might see the same value, leading to lots of duplication. You...(read more)

• Python: Dynamic attribute name generation without exec() or eval()

  - by PyNewbie27

  Hi, I'm trying to dynamically create buttons at runtime with PyQT4.7 However, this being my first python program I'm not sure how to get the functionality I want. I would like to be able to substitute a text string for an attribute name: i.e. for each in xrange(4): myname = "tab1_button%s" % each #tab1_button0, tab1_button1, tab1_button2 #self.ui.tab1_button0 = QtGui.QPushButton(self.ui.tab) <--normal code to create a named button setattr(self.ui,myname,QtGui.QPushButton(self.ui.tab)) #rewrite of line above to dynamicly generate a button #here's where I get stuck. this code isn't valid, but it shows what i want to do self.ui.gridLayout.addWidget(self.ui.%s) % myname #I need to have %s be tab1_button1, tab1_button2, etc. I know the % is for string substituion but how can I substitute the dynamically generated attribute name into that statement? I assume there's a basica language construct I'm missing that allows this. Since it's my first program, please take it easy on me ;)

• SQL Rally Nordic & Amsterdam slides & demos

  - by Davide Mauri

  Last week I had the pleasure to speak at two GREAT conferences (as you can see from the wordcloud I’ve posted, here for Stockholm and here for Amsterdam. I used two different filtering techniques to produce the wordcloud, that’s why they look different. I’m playing a lot with R in these days…so I like to experiment different stuff). The workshop with my friend Thomas Kejser on “Data Warehouse Modeling – Making the Right Choices” and my sessions on “Automating DWH Patterns through Metadata” has been really appreciated by attendees, give the amount of good feedback I had on twitter and on some blog posts (Here and here). Of course many asked for slides & demos to download, so here you are! Automating DWH Patterns through Metadata – Stockholm http://sdrv.ms/1bcRAaW Automating DWH Patterns through Metadata – Amsterdam http://sdrv.ms/1cNDAex I’m still trying to understand if and how I can publicly post slides & demos of the workshop, so for that you have to wait a couple of days. I will post about it as soon as possible. Anyway, if you were in the workshop and would like to get the slide & demos ASAP, just send me an email, I’ll happily sent the protected link to my skydrive folder to you. Enjoy!

• authentication question (security code generation logic)

  - by Stick it to THE MAN

  I have a security number generator device, small enough to go on a key-ring, which has a six digit LCD display and a button. After I have entered my account name and password on an online form, I press the button on the security device and enter the security code number which is displayed. I get a different number every time I press the button and the number generator has a serial number on the back which I had to input during the account set-up procedure. I would like to incorporate similar functionality in my website. As far as I understand, these are the main components: Generate a unique N digit aplha-numeric sequence during registration and assign to user (permanently) Allow user to generate an N (or M?) digit aplha-numeric sequence remotely For now, I dont care about the hardware side, I am only interested in knowing how I may choose a suitable algorithm that will allow the user to generate an N (or M?) long aplha-numeric sequence - presumably, using his unique ID as a seed Identify the user from the number generated in step 2 (which decryption method is the most robust to do this?) I have the following questions: Have I identified all the steps required in such an authentication system?, if not please point out what I have missed and why it is important What are the most robust encryption/decryption algorithms I can use for steps 1 through 3 (preferably using 64bits)?

• Managing multiple customer databases in ASP.NET MVC application

  - by Robert Harvey

  I am building an application that requires separate SQL Server databases for each customer. To achieve this, I need to be able to create a new customer folder, put a copy of a prototype database in the folder, change the name of the database, and attach it as a new "database instance" to SQL Server. The prototype database contains all of the required table, field and index definitions, but no data records. I will be using SMO to manage attaching, detaching and renaming the databases. In the process of creating the prototype database, I tried attaching a copy of the database (companion .MDF, .LDF pair) to SQL Server, using Sql Server Management Studio, and discovered that SSMS expects the database to reside in c:\program files\Microsoft SQL Server\MSSQL.1\MSSQL\DATA\MyDatabaseName.MDF Is this a "feature" of SQL Server? Is there a way to manage individual databases in separate directories? Or am I going to have to put all of the customer databases in the same directory? (I was hoping for a little better control than this). NOTE: I am currently using SQL Server Express, but for testing purposes only. The production database will be SQL Server 2008, Enterprise version. So "User Instances" are not an option.

• Utility Queries–Database Files, (and Filegroups)

  It has been a while since I last posted a utility query, and today, to avoid other work I am supposed to be doing, I decided to go ahead and work on another post.  Today, I went ahead and worked on a server configuration type query. One query I find I use pretty often is the following one that lists the files in the database. In this blog I will include 3 queries.  The first will deal with files and databases, and the second runs in a database to see the files and their filegroups (If there...(read more)

• C# : Forcing a clean run in a long running SQL reader loop?

  - by Wardy

  I have a SQL data reader that reads 2 columns from a sql db table. once it has done its bit it then starts again selecting another 2 columns. I would pull the whole lot in one go but that presents a whole other set of challenges. My problem is that the table contains a large amount of data (some 3 million rows or so) which makes working with the entire set a bit of a problem. I'm trying to validate the field values so i'm pulling the ID column then one of the other cols and running each value in the column through a validation pipeline where the results are stored in another database. My problem is that when the reader hits the end of handlin one column I need to force it to immediately clean up every little block of ram used as this process uses about 700MB and it has about 200 columns to go through. Without a full Garbage Collect I will definately run out of ram. Anyone got any ideas how I can do this? I'm using lots of small reusable objects, my thought was that I could just call GC.Collect() on the end of each read cycle and that would flush everything out, unfortunately that isn't happening for some reason.

• SQL Server Database Settings

  - by rbishop

  For those using Data Relationship Management on Oracle DB this does not apply, but for those using Microsoft SQL Server it is highly recommended that you run with Snapshot Isolation Mode. The Data Governance module will not function correctly without this mode enabled. All new Data Relationship Management repositories are created with this mode enabled by default. This mode makes SQL Server (2005+) behave more like Oracle DB where readers simply see older versions of rows while a write is in progress, instead of readers being blocked by locks while a write takes place. Many common sources of deadlocks are eliminated. For example, if one user starts a 5 minute transaction updating half the rows in a table, without snapshot isolation everyone else reading the table will be blocked waiting. With snapshot isolation, they will see the rows as they were before the write transaction started. Conversely, if the readers had started first, the writer won't be stuck waiting for them to finish reading... the writes can begin immediately without affecting the current transactions. To make this change, make sure no one is using the target database (eg: put it into single-user mode), then run these commands: ALTER DATABASE [DB] SET ALLOW_SNAPSHOT_ISOLATION ONALTER DATABASE [DB] SET READ_COMMITTED_SNAPSHOT ON Please make sure you coordinate with your DBA team to ensure tempdb is appropriately setup to support snapshot isolation mode, as the extra row versions are stored in tempdb until the transactions are committed. Let me take this opportunity to extremely strongly highly recommend that you use solid state storage for your databases with appropriate iSCSI, FiberChannel, or SAN bandwidth. The performance gains are significant and there is no excuse for not using 100% solid state storage in 2013. Actually unless you need to store petabytes of archival data, there is no excuse for using hard drives in any systems, whether laptops, desktops, application servers, or database servers. The productivity benefits alone are tremendous, not to mention power consumption, heat, etc.

• Analyzing the errorlog

  - by TiborKaraszi

  How often do you do this? Look over each message (type) in the errorlog file and determine whether this is something you want to act on. Sure, some (but not all) of you have some monitoring solution in place, but are you 100% confident that it really will notify for all messages that you might find interesting? That there isn't even one little message hiding in there that you would find valuable knowing about? Or how about messages that you typically don't are about, but knowing that you have a high...(read more)

• Looking for a good explanation of the table generation macro idiom

  - by detly

  I want to make this clear up front : I know how this trick works, what I want is a link to a clear explanation to share with others. One of the answers to a C macro question talks about the "X macro" or "not yet defined macro" idiom. This involves defining something like: #define MAGIC_LIST \ X(name_1, default_1) \ X(name_2, default_2) \ ... Then to create, say, an array of values with named indices you do: typedef enum { #define X(name, val) name, MAGIC_LIST #undef X } NamedDefaults; You can repeat the procedure with a different #define for X() to create an array of values, and maybe debugging strings, etc. I'd like a link to a clear explanation of how this works, pitched at someone who is passably familiar with C. I have no idea what everyone usually calls this pattern, though, so my attempts to search the web for it have failed thus far. (If there is such an explanation on SO, that'd be fine...)

• Automatic database generation / migration with perl

  - by pistacchio

  Hi, In Ror or Django or web2py you can "describe" a database (as a set of classes that remaps to tables) and the framework (having being provided with a connection string to the desired database) generates the tables, fields, relations and in the case of RoR and web2py it also keeps it up-to-date (eg, removing a class drops the table, adding a property to the class triggers an "alter table add" etc). Is there any perl module that does the same? Eg, it takes the YAML / XML / JSON description of a database as input and modifies / generates the database accordingly? Thanks in advance.
