• Are database triggers evil?

  - by WW

  Are database triggers a bad idea? In my experience they are evil, because they can result in surprising side effects, and are difficult to debug (especially when one trigger fires another). Often developers do not even think of looking if there is a trigger. On the other hand, it seems like if you have logic that must occur evertime a new FOO is created in the database then the most foolproof place to put it is an insert trigger on the FOO table. The only time we're using triggers is for really simple things like setting the ModifiedDate.

• Using the Antenna and J2ME Polish preprocessors interchangeably and setting a variable value

  - by walter

  I have J2ME code, which I want to be able to compile using the J2ME Polish preprocessor or the wtkpreprocessor (antenna). They mostly use the same directives so it usually works, but ... When I want to insert an URL value in the Java code this gives a problem. In Antenna the code would look like this: //#ifdef my.url //# System.out.println("My Url"); //#expand String location = "%my.url%"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif and in J2ME Polish it would look like this: //#ifdef my.url:defined //# System.out.println("My Url"); //#= String location = "${my.url}"; //#else System.out.println("Default"); String location = "http://www.some.default.url.com"; //#endif I want some way in which I can use the preprocessors interchangeably and still be able to set the url in the build.xml, any ideas?

• Ivy: Publishing all artefacts in a directory

  - by Dave Flowers

  I'm looking to move to Apache Ivy for dependency management on one of our existing projects. The project publishes many artefacts, and the artefacts it produces are likely to change in the future, so I don't want to enumerate all of the publications in the ivy.xml file -- I'd like Ivy to just publish all the files in a given directory. I considered auto-generating a list of the files built and using XSLT to insert it into the ivy.xml, but that seems a little cumbersome for what I'd expect to be a reasonably common requirement. Is there a better way to do this? Can Ivy pick up all the files in a directory and ignore the publications in the Ivy file? Or is there some way to get Ivy to use different files for publication and for fetching, so I can avoid having to use XSLT to merge the files.

• SelectedValue of DropDownList is not the one I selected when Enabled=false

  - by anD666

  Hiya, I have a few DropDownLists on a webform each pointing to a SqlDataSource. Some of these datasources use one of these DropDownLists for a select parameter, filtering the list to specific categories. For certain users two of these DropDownLists are to be automatically set and disabled. When I submit the form with the drop downs enabled it works fine but when they are disabled the SelectedValue of the DropDownList is being reset to the first one in the list. My DropDownLists are constructed as follows: <asp:DropDownList ID="ddlManager" runat="server" DataSourceID="dsManagers" EnableViewState="false" DataValueField="ManagerID" DataTextField="MgrName" AppendDataBoundItems="false" ondatabound="ddlManager_DataBound" > The drop down lists add an extra item on the data bound event as follows: protected void ddlManager_DataBound(object sender, EventArgs e) { this.ddlManager.Items.Insert(0, new ListItem("--Manager--", "--Manager--")); } Can anyone shed any light as to why this is happening? Thanks Andy

• django file upload in 2 steps

  - by alexarsh

  Hi, I want to upload a file in 2 steps. First I want to upload it and show the errors and on the second step I want actually to save the file data in the database. So I made a simple form and my problem is how to pass the same file to the form on the second step? I mean how to insert request.FILES data in the same form again. Or maybe there is a better way? Thanks, Arshavski Alexander.

• Connecting to multiple firebird Databases via Delphi

  - by Branden

  I am integrating a system with 2 other applications, 1 using a Firebird database whilst the other BIS (using ADO). My delphi application uses Firebird. I need to read data from my database, insert it into both the BIS database and the other application firebird database. I have created seperate data modules for each. Sending data to the ADO works fine, but when writing to the other Firebird DB (my db still open) I get strange errors. I have managed to isolate the problem to the second firebird DB. Small data writes seems fine. The data structures are completly different, so un able to use a synch tool. is there a way to overcome this by using multi threading or seperate memory space each Firebird instance uses?

• error 2016: Condition cannot be specified for Column member

  - by IP

  I am having some issues with Entity Framework in VS2010 The problem I'm getting is described very well here... http://social.msdn.microsoft.com/Forums/en/adonetefx/thread/cacf6a76-09a8-4c90-9502-d8b87c2f6bea It's basically happening when a Foreign key is pointed at the primary key of another table...but if I take off the StoreGeneratedPattern as "Identity", then it tries to insert a value into the identity field ** EDIT So, what it seems to be is that EF4 can't handle a null relationship when the primary key is set to StoreGeneratedPattern="Identity". If I create a FK pointing to this primary key, and make it nullable (effectively creating a 0...M relationship), then it throws this compilation error. Removing StoreGeneratedPattern="Identity" fixes the issue, but causes issues elseware It works if the foreign key is set to not nullable

• Do MyISAM holes get filled in automatically?

  - by NNN

  When you run a delete on a MyISAM table, it leaves a hole in the table until the table is optimized. This affects concurrent inserts. On the default setting, concurrent_inserts only work for tables without holes. However, in the documentation for MyISAM, under the concurrent_insert section it says: Enables concurrent inserts for all MyISAM tables, even those that have holes. For a table with a hole, new rows are inserted at the end of the table if it is in use by another thread. Otherwise, MySQL acquires a normal write lock and inserts the row into the hole. http://dev.mysql.com/doc/refman/5.0/en/server-system-variables.html#sysvar_concurrent_insert Does that mean MyISAM automatically fills in holes whenever a new row is insert into the table? Previously I thought the holes would not be fixed until you OPTIMIZE a table.

• Correct sequence of actions when using Markdown & MySQL?

  - by Andrew Heath

  I want my users to be able to write an article in Markdown, have it stored in the MySQL database (with the option to edit it in the future), and displayed for other users. In practice, this is my understanding of how it works: INPUT user input via HTML form using Markdown syntax $queryInput = mysql_real_escape_string($userInput); insert sanitized string into database OUTPUT query field from database $output = Markdown($queryResult); display $output Is that it? Does PHP Markdown preclude the need for htmlspecialchars or Pure HTML ? Thanks!

• Importing an Excel WorkSheet into a Datatable

  - by Nick LaMarca

  I have been asked to create import functionality in my application. I am getting an excel worksheet as input. The worksheet has column headers followed by data. The users want to simply select an xls file from their system, click upload and the tool deletes the table in the database and adds this new data. I thought the best way would be too bring the data into a datatable object and do a foeach for every row in the datatable insert row by row into the db. My question is what can anyone give me code to open an excel file, know what line the data starts on in the file, and import the data into a datable object?

• Cloning java ArrayList and preventing it from modifications

  - by user222164

  I have a data structure like a database Rowset, which has got Rows and Rows have Columns. I need to initialize a Columns with null values, current code is to loop thru each column for a row and initialize values to NULL. Which is very inefficient if you have 100s or rows and 10s of column. So instead I am keeping a initialized ArrayList of columns are RowSet level, and then doing a clone of this Arraylist for individual rows, as I believe clone() is faster than looping thru each element. row.columnsValues = rowsset.NullArrayList.clone() Problem with this is NullArrayList can be accidentally modified after being cloned, thus sacrificing the integrity of ArrayList at RowSet level, to prevent I am doing 3 things 1) Delcaring ArrayList as final 2) Any elements I insert are final or null 3) Methods thurough this arrayList are passed to other arrays are declared a final. Sounds like a plan, do you see any holes ?

• Splitting string on probable English word boundaries

  - by Sean

  I recently used Adobe Acrobat Pro's OCR feature to process a Japanese kanji dictionary. The overall quality of the output is generally quite a bit better than I'd hoped, but word boundaries in the English portions of the text have often been lost. For example, here's one line from my file: softening;weakening(ofthemarket)8 CHANGE [transform] oneselfINTO,takethe form of; disguise oneself I could go around and insert the missing word boundaries everywhere, but this would be adding to what is already a substantial task. I'm hoping that there might exist software which can analyze text like this, where some of the words run together, and split the text on probable word boundaries. Is there such a package? I'm using Emacs, so it'd be extra-sweet if the package in question were already an Emacs package or could be readily integrated into Emacs, so that I could simply put my cursor on a line like the above and repeatedly invoke some command that splits the line on word boundaries in decreasing order of probable correctness.

• MySQL, C++: Retrieving auto-increment ID

  - by Thomas Matthews

  I have a table with an auto-incrementing ID. After inserting a new row, I would like to retrieve the new ID. I found an article that used the MySQL function LAST_INSERT_ID(). The article says to create a new query and submit it. I'm using MySQL Connector C++, Windows XP and Vista, and Visual Studio 9. Here are my questions: Is there an API, for the connector, that will fetch the ID out of the record? Does the result set, after an insert/append, contain the new ID? The LAST_INSERT_ID is MySQL specific. Is there an SQL standard method for obtaining the new ID?

• LINQ to SQL SubmitChangess() progress

  - by Emir

  I'm using LINQ to SQLto import old DBF files into MSSQL. I'm reading all rows and adding them to database using ctx.MyTable.InsertOnSubmit(row) After reading phase is completed I have around 100 000 pending inserts. ctx.SubmitChanges() naturally is taking a long time. Is there any way to track progress of the ctx.submitchanges()? Can ctx.Log somehow be used for this purpose? Update: Is it possible to use ctx.GetChangeSet().Inserts.Count and track insert statements using the Log? Dividing ctx.SubmitChanges() into smaller chunks is not working for me, because I need transaction, all or nothing. Update 2: I've found nice class ActionTextWriter using which I will try to count inserts. http://damieng.com/blog/2008/07/30/linq-to-sql-log-to-debug-window-file-memory-or-multiple-writers

• Mapping class properties to generic columns in table .NET

  - by Tony_Henrich

  I have have a SQL Server table which has generic names like Text1, Text2.. etc. The table was designed like this because the same structure is used for different projects. I have a class in .NET which has properties. Say a Customer class has a property called FirstName. How can I do the mapping from FirstName to Text1 just once (central place) in the application so that I don't have to remember and hard code the mappings all over the app when I create the different DAL methods? For example, I want the app to know when I want to update, insert a FirstName, the DAL automatically uses Text1. Basically I don't have to remember which property goes to which column. The idea is so the developers do not map the properlies/columns in a wrong way. It's always consistent. Note: Database inserts, updates and deletes are allowed through stored procedures only.

• What should every programmer know?

  - by Matt Lacey

  Regardless of programming language(s) or operating system(s) used or the environment they develop for, what should every programmer know? Some background: I'm interested in becoming the best programmer I can. As part of this process I'm trying to understand what I don't know and would benefit me a lot if I did. While there are loads of lists around along the lines of "n things every [insert programming language] developer should know", I have yet to find anything similar which isn't limited to a specific language. I also expect this information to be of interest and benefit to others.

• JSF 2 Scriptmanager style functionality

  - by CDSO1

  I need to be able to add some javascript to all ajax postback responses (PartialViewContext.isAjaxRequest == true) but I am not succeeding with any implementation I try. I have tried implementing a PhaseListener and adding my script using PartialResponseWriter.insert* to add eval blocks, as well as trying to add the script by creating a script element. (Results in CDATA cannot nest, or just invalid XML) I have tried decorating PartialViewContextFactory to override the PartialViewContext.processPartial and add the script after the wrapped instance has processed it... How should I go about adding sripts to an Ajax response? Something similar to what .NET has with Scriptmanager.registerClientScriptBlock preferably. Thank you

• Are we asking too much of transactional memory?

  - by Carl Seleborg

  I've been reading up a lot about transactional memory lately. There is a bit of hype around TM, so a lot of people are enthusiastic about it, and it does provide solutions for painful problems with locking, but you regularly also see complaints: You can't do I/O You have to write your atomic sections so they can run several times (be careful with your local variables!) Software transactional memory offers poor performance [Insert your pet peeve here] I understand these concerns: more often than not, you find articles about STMs that only run on some particular hardware that supports some really nifty atomic operation (like LL/SC), or it has to be supported by some imaginary compiler, or it requires that all accesses to memory be transactional, it introduces type constraints monad-style, etc. And above all: these are real problems. This has lead me to ask myself: what speaks against local use of transactional memory as a replacement for locks? Would this already bring enough value, or must transactional memory be used all over the place if used at all?

• Dynamic openrowset in T-Sql Function or viable alternative?

  - by IronicMuffin

  I'm not quite sure how to phrase this. Here is the problem: I have 1-n items that I need to join to a different system (AS400) to get some data. The openrowset takes forever if I specify the where criteria outside of the openrowset, e.g.: select * from openrowset('my connection string', 'select code, myfield from myTable') where code = @code My idea was to create a function that takes in the item number and uses dynamic sql to inject it into the openrowset string, a la: declare @cmd varchar(1000) set @cmd = 'select * from openrowset('my connection string', ''select code, myfield from myTable where code = ' + @code + ''')' Apparently I can't use the insert.. exec.. strategy inside of a function. Is there any better way to achieve this? I was going to use this in joins where I needed the external data using cross apply. I'm not married to tvf and cross apply, but I do need a method of getting this data quickly. Thanks for any help.

• emacs indentation in asm mode

  - by Gauthier

  I am looking for the equivalent of c-indent-level and ruby-indent-level, for asm-mode. That is, I want to force the indentation to 4 spaces, and I want them to be replaced with blanks. What I've seen tells me it does not exist for asm-mode. Could someone please tell me this is wrong? I tried this also: http://stackoverflow.com/questions/69934/set-4-space-indent-in-emacs-in-text-mode , to no av. I have tried: (setq tab-width 4) (setq indent-line-function 'insert-tab) (setq asm-indent-level 4) This works however: (custom-set-variables '(tab-stop-list (quote (4 8 12 16 20 24 28 32 36 40 44 48 52 56 60 64 68 72 76 80 84 88 92 96 100 104 108 112 116 120)))) But I wonder if there is a way to define that for asm-mode only. What if I wanted to keep the default tab behaviour for other modes?
