  • How do you unit test your T-SQL

    - by AlexKuznetsov
    How do you unit test your T-SQL? Which libraries/tools do you use? What percentage of your code is covered by unit tests and how do you measure it? Do you think the time and effort which you invested in your unit testing harness has paid off or not? If you do not use unit testing, can you explain why not?

  • Ordering sql query results

    - by user343409
    My sql query gives the columns: product_id (which is an integer) pnl (which is float - can be negative) I get more than 100 rows. I want to filter out the top 40 rows based on abs(pnl). But the results should be ordered by pnl column only and not by abs(pnl). I want to do this for MSSQL 2005. Is there a way to do this?

  • How to prevent latex memory overflow

    - by drasto
    I've got a latex macro that makes small pictures. In that picture I need to draw area. Borders of that area are quadratic bezier curves and that area is to be filled. I did not know how to do it so currently I'm "filling" the area by drawing a plenty of bezier curves inside it... This slows down typeseting and when a macro is used multiple times (so tex is drawing really a lot of quadratic bezier curves) it produces following error: ! TeX capacity exceeded, sorry [main memory size=3000000]. How can I prevent this error ? (by freeing memory after macro or such...) Or even better how do I fill the area determined by two quadratic bezier curves? Code that produces error: \usepackage{forloop} \usepackage{picture} \usepackage{eepic} ... \linethickness{\lineThickness\unitlength}% \forloop[\lineThickness]{cy}{\cymin}{\value{cy} < \cymax}{% \qbezier(\ax, \ay)(\cx, \value{cy})(\bx, \by)% }% Here are some example values for variables: \setlength{\unitlength}{0.01pt} \lineThickness=20 %cy is just a counter - inital value is not important \cymin=450 \cymax=900 %from following only the difference between \ax and \bx is important \ax=0 \ay=0 \bx=550 \by=0 Note: To reproduce the error this code have to execute approximately 150 times (could be more depending on your latex memory settings). Thanks a lot for any help

  • C++ Memory Leak, Can't find where

    - by Nicholas
    I'm using Visual Studio 2008, Developing an OpenGL window. I've created several classes for creating a skeleton, one for joints, one for skin, one for a Body(which is a holder for several joints and skin) and one for reading a skel/skin file. Within each of my classes, I'm using pointers for most of my data, most of which are declared using = new int[XX]. I have a destructor for each Class that deletes the pointers, using delete[XX]. Within my GLUT display function I have it declaring a body, opening the files and drawing them, then deleting the body at the end of the display. But there's still a memory leak somewhere in the program. As Time goes on, it's memory usage just keep increasing, at a consistent rate, which I'm interpreting as something that's not getting deleted. I'm not sure if it's something in the glut display function that's just not deleting the Body class, or something else. I've followed the steps for memory leak detection in Visual Studio 2008 and it doesn't report any leak, but I'm not 100% sure if it's working right for me. I'm not fluent in C++, so there maybe something I'm overlooking, can anyone see it?

  • Can this code cause a memory leak (Arduino)

    - by tbraun89
    I have a arduino project and I created this struct: struct Project { boolean status; String name; struct Project* nextProject; }; In my application I parse some data and create Project objects. To have them in a list there is a pointer to the nextProject in each Project object expect the last. This is the code where I add new projects: void RssParser::addProject(boolean tempProjectStatus, String tempData) { if (!startProject) { startProject = true; firstProject.status = tempProjectStatus; firstProject.name = tempData; firstProject.nextProject = NULL; ptrToLastProject = &firstProject; } else { ptrToLastProject->nextProject = new Project(); ptrToLastProject->nextProject->status = tempProjectStatus; ptrToLastProject->nextProject->name = tempData; ptrToLastProject->nextProject->nextProject = NULL; ptrToLastProject = ptrToLastProject->nextProject; } } firstProject is an private instance variable and defined in the header file like this: Project firstProject; So if there actually no project was added, I use firstProject, to add a new one, if firstProject is set I use the nextProject pointer. Also I have a reset() method that deletes the pointer to the projects: void RssParser::reset() { delete ptrToLastProject; delete firstProject.nextProject; startProject = false; } After each parsing run I call reset() the problem is that the memory used is not released. If I comment out the addProject method there are no issues with my memory. Someone can tell me what could cause the memory leak?

  • Android - Memory leak when dynamically building UI with image resource backgrounds

    - by Rich
    I have an Activity that I swear is leaking memory. The app I'm working on does a lot with images, so I've had to be pretty stingy with memory when working directly with Bitmaps. I added an Activity, and now if you use this new Activity it basically puts me over the edge with mem usage and I end up throwing the "Bitmap exceeds VM budget" exception. If you never launch this Activity, everything is smooth as it was previously. I started reading about memory leaks, and I think that I have a similar situation to what is described in the article in the Android docs. I'm dynamically creating a bunch of image views and adding a BackgroundDrawable from the resources and adding an OnClickListener as well. I imagine I have to do some cleanup when the Activity hits onPause in its life cycle, but I'd like to know specifically what is the correct way. Here is the code that should demonstrate the objects I'm working with... LinearLayout templateContainer; . . . ImageView imgTemplatePreview = (ImageView) item.findViewById(R.id.imgTemplatePreview); . . . imgTemplatePreview.setBackgroundDrawable(getResources().getDrawable(previewId)); imgTemplatePreview.setOnClickListener(imgClick); templateContainer.addView(item);

  • Oracle Open World 2012: SQL Developer Recap

    - by thatjeffsmith
    Last week was the ‘big show’ in San Francisco. I was very happy to meet many of you in person. And many of you had questions – lots of questions! We had full or overflowing rooms for our sessions and hands-on-labs. The SQL Developer ‘booths’ were also slammed several times. So exciting to see so many of YOU excited about SQL Developer. It’s very cool to hear the stories of our tools saving you and your organizations so much time (and money!) Instead of doing a Day 0 – Day 9 recap, I thought I’d share with you the questions that I heard more than once. And just for giggles, I’ll throw in some answers as well So in no particular order… What’s the difference between Oracle SQL Developer & Oracle SQL Developer Data Modeler? Mathematically speaking – two words. But as far as the actual modeling features go, there’s no difference between the two applications. The same ‘code’ or features as it pertains to data modeling and design are in both tools. However, in SQL Developer you have all of the OTHER features fighting for real estate in the UI. So I have a general rule of thumb – if you spend MOST of your time in the database, use SQL Developer. And if you spend most of your time in the data model, run the separate and dedicated program, Oracle SQL Developer Data Modeler. Here’s a couple of screenshots to drive home the UI point: Oracle SQL Developer Oracle SQL Developer Data Modeler running INSIDE of SQL Developer. Notice how the Modeler menu items fold under the file menu? Oracle SQL Developer Data Modeler Easier to navigate and manipulate your models with the stand alone modeler. Just no worksheet to run your ad-hoc queries, etc. Don’t forget you can disable the Data Modeler inside of SQL Developer via the Extensions preference page. How can I model my table partitions? Partitioning is defined via the Physical model. So after you have finished your relational model, you need to generate a physical model. Oracle SQL Developer Data Modeler Physical Model and Partitioning Open the properties for your physical model table. Enable the ‘partitioned’ property. Once you do so, the ‘Partitioning’ page will activate. Lots and lots of partitioning support and options here But what about Interval Partitioning? An extension of range partitioning in 11gR2, we don’t currently support this partitioning scheme in SQL Developer. But we’re working on it! Can SQL Developer ignore column order when comparing models? Yes! After you start a model compare, one of your options is to disregard the order of an attribute or column definition. Tell SQL Developer you don’t care when your column shows up, just as long as it DOES show up. Wow, you got a lot of questions around modeling! Is that normal? Yes! While we appreciate that many folks inherit their applications and associated designs, new applications are being ‘born’ every day. Since both of our tools are free for anyone to design their new Oracle applications with, we attract a fair amount of attention I want to do a Hands On Lab. How do I get your software and instructional guides? Go here. Download VirtualBox. Then download the VB image. Import the appliance. Start it. Connect oracle/oracle on the OEL VM. Click on ‘Start Here’ in the desktop. Follow the instructions. If you need help, ask away! You went too fast in your Tips & Tricks session. Do you have cliff notes? Yes! And you’re SO close to finding them! Just go to my SQL Developer resources page. All of my tips are documented on this blog somewhere. I’ve indexed the most popular ones on the resource page. You can use the Search dialog on the right to find the rest. Or just send me a comment or question, and I’ll do my best to answer them as they come in.

  • Why isn't DSM for unstructured memory done today?

    - by sinned
    Ages ago, Djikstra invented IPC through mutexes which then somehow led to shared memory (SHM) in multics (which afaik had the necessary mmap first). Then computer networks came up and DSM (distributed SHM) was invented for IPC between computers. So DSM is basically a not prestructured memory region (like a SHM) that magically get's synchronized between computers without the applications programmer taking action. Implementations include Treadmarks (inofficially dead now) and CRL. But then someone thought this is not the right way to do it and invented Linda & tuplespaces. Current implementations include JavaSpaces and GigaSpaces. Here, you have to structure your data into tuples. Other ways to achieve similar effects may be the use of a relational database or a key-value-store like RIAK. Although someone might argue, I don't consider them as DSM since there is no coherent memory region where you can put data structures in as you like but have to structure your data which can be hard if it is continuous and administration like locking can not be done for hard coded parts (=tuples, ...). Why is there no DSM implementation today or am I just unable to find one?

  • SQL Server 2005 - Syncing development/production databases

    - by hamlin11
    I've got a rather large SQL Server 2005 database that is under constant development. Every so often, I either get a new developer or need to deploy wide-scale schema changes to the production server. My main concern is deploying schema + data updates to developer machines from the "master" development copy. Is there some built-in functionality or tools for publishing schema + data in such a fashion? I'd like it to take as little time as possible. Can it be done from within SSMS? Thanks in advance for your time

  • Conditional Operator in SQL Where Clause

    - by Marc
    I'm wishing I could do something like the following in SQl Server 2005 (which I know isnt valid) for my where clause. Sometimes @teamID (passed into a stored procedure) will be the value of an existing teamID, otherwise it will always be zero and I want all rows from the Team table. I researched using Case and the operator needs to come before or after the entire statement which prevents me from having a different operator based on the value of @teamid. Any suggestions other than duplicating my select statements. declare @teamid int set @teamid = 0 Select Team.teamID From Team case @teamid when 0 then WHERE Team.teamID > 0 else WHERE Team.teamID = @teamid end

  • Find earliest and latest dates of specified records from a table using SQL

    - by tonyyeb
    Hi I have a table (in MS SQL 2005) with a selection of dates. I want to be able to apply a WHERE statement to return a group of them and then return which date is the earliest from one column and which one is the latest from another column. Here is an example table: ID StartDate EndDate Person 1 01/03/2010 03/03/2010 Paul 2 12/05/2010 22/05/2010 Steve 3 04/03/2101 08/03/2010 Paul So I want to return all the records where Person = 'Paul'. But return something like (earliest ) StartDate = 01/03/2010 (from record ID 1) and (latest) EndDate = 08/03/2010 (from record ID 3). Thanks in advance

  • Changing SQL Server Database sorting

    - by plaisthos
    I have a request to change the collation of a SQL Server Database: ALTER DATABASE solarwind95 collate SQL_Latin1_General_CP1_CI_AS but I get this strange error: Meldung 5075, Ebene 16, Status 1, Zeile 1 Das 'Spalte'-Objekt 'CustomPollerAssignment.PollerID' ist von 'Datenbanksortierung' abhängig. Die Datenbanksortierung kann nicht geändert werden, wenn ein schemagebundenes Objekt von ihr abhängig ist. Entfernen Sie die Anhängigkeiten der Datenbanksortierung, und wiederholen Sie den Vorgang. Sorry for the german errror message. I do not know how to switch the language to english, but here is a translation: Translation: Message 5075, Layer 16, Status 1, Row 1 The 'column' object 'CustomPollerAssignment.PollerID' depends on 'Database sorting. The database sorting cannot be changed if a schema bound object depends on it. Remove the dependency of the database sortieren and retry. I got a ton more of the errors like that.

  • SQL server 2005 - user rights

    - by Paresh
    I have created one user named "tuser" with create database rights in SQL server 2005. and given the 'db_owner' database role of master and msdb database to "tuser". From this user login when I run the script for create database then it will create new database. But "tuser" don't have access that newly created database generated from script. Any one have any idea?, I want to write the script so "tuser" have access that new created database after creation and can have add user permission of newly created database. I want to give 'db_owner' database roles to "tuser" on that newly created database in the same script which create new database. The script run under 'tuser'.

  • send dbmail on @@error from sql server 2005

    - by Ved
    Hi, I am trying to send database mail when error occurs inside the transaction.My setup for dbo.sp_send_dbmail is correct , when I execute the proc I do get an email within 1 min. However when I try to use dbo.sp_send_dbmail inside another proc within transactions than I do not get the email. Sql server does show in the result window that "Mail queued" but I never receive it. BEGIN TRANSACTION DECLARE @err int DECLARE @test nvarchar(max) RAISERROR('This is a test', 16, 1) SELECT @err = @@ERROR IF @err < 0 BEGIN SET @test = error_message() EXEC msdb.dbo.sp_send_dbmail @recipients= '[email protected]', @body = 'test inside', @subject = 'Error with proc', @body_format = 'HTML', @append_query_error = 1, @profile_name ='Database Mail Profile'; ROLLBACK TRANSACTION RETURN END COMMIT TRANSACTION And I get result as Msg 50000, Level 16, State 1, Line 7 This is a test Mail queued.

  • Is it possible to create a new T-SQL Operator using CLR Code in SQL Server?

    - by Eoin Campbell
    I have a very simple CLR Function for doing Regex Matching public static SqlBoolean RegExMatch(SqlString input, SqlString pattern) { if (input.IsNull || pattern.IsNull) return SqlBoolean.False; return Regex.IsMatch(input.Value, pattern.Value, RegexOptions.IgnoreCase); } It allows me to write a SQL Statement Like. SELECT * FROM dbo.table1 WHERE dbo.RegexMatch(column1, '[0-9][A-Z]') = 1 -- match entries in col1 like 1A, 2B etc... I'm just thinking it would be nice to reformulate that query so it could be called like SELECT * FROM dbo.table1 WHERE column1 REGEXLIKE '[0-9][A-Z]' Is it possible to create new comparison operators using CLR Code. (I'm guessing from my brief glance around the web that the answer is NO, but no harm asking)

  • SQL CHECK constraint issues

    - by blahblah
    I'm using SQL Server 2008 and I have a table with three columns: Length, StartTime and EndTime. I want to make a CHECK constraint on this table which says that: if Length == NULL then StartTime <> NULL and EndTime <> NULL else StartTime == NULL and EndTime == NULL I've begun to try things like this: Length == NULL AND StartTime <> NULL AND EndTime <> NULL Obviously this is not enough, but even this simple expression will not validate. I get the error: "Error validating 'CK_Test_Length_Or_Time'. Do you want to edit the constraint?" Any ideas on how to go about doing this?

  • to_date in SQL Server 2005

    - by Chin
    Does any one know how I would have to change the following to work with ms sql? WHERE registrationDate between to_date ('2003/01/01', 'yyyy/mm/dd') AND to_date ('2003/12/31', 'yyyy/mm/dd'); What I have read implies I would have to construct it using DATEPART() which could become very long winded. Especially when the goal would be to compare on dates which I receive in the following format "2003-12-30 10:07:42". It would be nice to pass them off to the database as is. Any pointers appreciated.

  • Complex select query question for hardcore SQL designers

    - by eugeneK
    Very complex query been trying to construct it for few days with more real success. I'm using SQL-SERVER 2005 Standard What i need is : 5 CampaignVariants from Campaigns whereas 2 are with the largest PPU number set and 3 are random. Next condition is that CampaignDailyBudget and CampaignTotalBudget are below what is set in Campaign ( calculation is number of clicks in Visitors table connected to Campaigns via CampaignVariants on which users click) Next condition CampaignLanguage, CampaignCategory, CampaignRegion and CampaignCountry must be the ones i send to this select with (languageID,categoryID,regionID and countryID). Next condition is that IP address i send to this select statement won't be in IPs list for current Campaign ( i delete inactive for 24 hours IPs ). In other words it gets 5 CampaignVariants for user that enters the site, when i take from user PublisherRegionUID,IP,Language,Country and Region view diagram

  • SQL - Two foreign keys that have a dependency between them

    - by Brian
    The current structure is as follows: Table RowType: RowTypeID Table RowSubType: RowSubTypeID FK_RowTypeID Table ColumnDef: FK_RowTypeID FK_RowSubTypeID (nullable) In short, I'm mapping column definitions to rows. In some cases, those rows have subtype(s), which will have column definitions specific to them. Alternatively, I could hang those column definitions that are specific to subtypes off their own table, or I could combine the data in RowType and RowSubType into one table and work with a single ID, but I'm not sure either is a better solution (if anything, I'd lean towards the latter, as we mostly end up pulling ColumnDefs for a given RowType/RowSubType). Is the current design SQL Blasphemy? If I keep the current structuree, how do I maintain that if RowSubTypeID is specified in ColumnDef, that it must correspond to the RowType specified by RowTypeID? Should I try to enforce this with a trigger or am I missing a simple redesign that would solve the problem?
