  • ADO.NET Entity Framework with OLE DB Access Data Source

    - by Tim Long
    Has anyone found a way to make the ADO.NET Entity Framework work with OLE DB or ODBC data sources? Specifically, I need to work with an Access database that for various reasons can't be upsized to SQL. This MSDN page says: The .NET Framework includes ADO.NET providers for direct access to Microsoft SQL Server (including Entity Framework support), and for indirect access to other databases with ODBC and OLE DB drivers (see .NET Framework Data Providers). For direct access to other databases, many third-party providers are available as shown below. The reference to "indirect access to other databases" is tantalising but I confess that I am hopelessly confused by all the different names for data access technology.

  • How to support 3-byte UTF-8 Characters in ANT

    - by efelton
    I am trying to support UTF-8 characters in my ANT script. As long as the character string are made up of 2-byte UTF-8 characters, such as: Lògìñ Ùsèr ÌÐ Then things work fine. When I use Unicode Han Character: ? Which, according to this site: http://www.fileformat.info/info/unicode/char/6211/index.htm Has a UTF-8 encoding of 0xE6 0x88 0x91 I can see in UltraEdit, my input properties file has the values "E6 88 91" all in a row, so I'm fairly confident that my input is correct. And When I open the same file in Notepad++ I can see all the characters correctly. Here is my Build Script: <?xml version="1.0" encoding="UTF-8" ?> <project name="utf8test" default="all" basedir="."> <target name="all"> <loadproperties encoding="UTF-8" srcfile="./apps.properties.all.txt" /> <echo>No encoding ${common.app.name}</echo> <echo encoding="UTF-8">UTF-8 ${common.app.name}</echo> <echo encoding="UnicodeLittle">UnicodeLittle ${common.app.name}</echo> <echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.name}</echo> <echo>${common.app.ServerName}</echo> <echo>${bb.vendor}</echo> <echo>No encoding ${common.app.UserIdText}</echo> <echo encoding="UTF-8">UTF-8 ${common.app.UserIdText}</echo> <echo encoding="UnicodeLittle">UnicodeLittle ${common.app.UserIdText}</echo> <echo encoding="UnicodeLittleUnmarked">UnicodeLittleUnmarked ${common.app.UserIdText}</echo> <echoproperties /> </target> </project> And here is my properties file: common.app=VrvPsLTst common.app.name=?? common.app.description=Pseudo Loc Test App for Build Script testing common.app.ServerName=http://Vèrìvò.com bb.vendor=Vèrìvò common.app.PasswordText=Pàsswòrð bb.override.list=MP_COPYRIGHTTEXT, "Çòpÿrìght 2012 Vèrívó Bùîlð TéàM" common.app.LoginButtonText=Lògìñ common.app.UserIdText=Ùsèr ÌÐ bb.SMSSuccess=Mèssàgéß Sùççêssfúllÿ Sëñt common.app.LoginScreenMessage=WèlçòMé Mêssàgë common.app.LoginProgressMessage=Àùthèñtìçàtíòñ îñ prógréss... ios.RegistrationText=Règìstràtíòñ Téxt ios.RegistrationURL=http://www.josscrowcroft.com/2011/code/utf-8-multibyte-characters-in-url-parameters-%E2%9C%93/ Here is what the output looks like: Buildfile: C:\Temp\utf8\build.xml all: [echo] No encoding ??

  • Qt static build with static mysql plugin confusion

    - by bdiloreto
    I have built a Qt application which uses the MySQL library, but I am confused by the documentation on static versus shared builds. From the Qt documentation at http://doc.qt.nokia.com/4.7/deployment-windows.html it says: To deploy plugin-based applications we should use the shared library approach. And on http://doc.qt.nokia.com/4.7/deployment.html, it says: Static linking results in a stand-alone executable. The advantage is that you will only have a few files to deploy. The disadvantages are that the executables are large and with no flexibility and that you cannot deploy plugins. To deploy plugin-based applications, you can use the shared library approach. But on http://doc.qt.nokia.com/latest/plugins-howto.html, it seems to say the opposite, giving directions on how to use static plugins: Plugins can be linked statically against your application. If you build the static version of Qt, this is the only option for including Qt's predefined plugins. Using static plugins makes the deployment less error-prone, but has the disadvantage that no functionality from plugins can be added without a complete rebuild and redistribution of the application. ... To link statically against those plugins, you need to use the Q_IMPORT_PLUGIN() macro in your application and you need to add the required plugins to your build using QTPLUGIN. I want to build the Qt libraries statically (for easy deployment) and then use the static MySQL plugin. To do this, I did NOT use the binary distrubtion for Windows. Instead, I've started with the source qt-everywhere-opensource-src-4.7.4 Is the following the correct way to do a static build so that i can use the static MySql plugin? configure -static -debug-and-release -opensource -platform win32-msvc2010 -no-qt3support -no-webkit -no-script -plugin-sql-mysql -I C:\MySQL\include -L C:\MySQL\lib This should build the Qt libraries statically AND the static plugin to be linked at run-time, correct? I would NOT need to build the Mysql Plugin from source separately, correct? If I was to subtitute "-qt-sql-mysql" for "-plugin-sql-mysql" in above, it would include the MySQL driver directly in the QT static libraries, in which case I would NOT need to use the plugin at all, correct? Thanks for making me unconfused!

  • How do I start bash in 13.04?

    - by Maik Klein
    I have a bash script that I need to execute. It seems that I can't run in in my terminal because it has a slightly different syntax. I could run the first file like bash ./configure but it produces a makefile that I can not use. If I try bash make it tells me that it can't execute make. How do I run this make file in bash? I tried cd /usr/bin ./bash but it tells me that it can't find bash. So how do I start bash?

  • SSAS Compare: an intern’s journey

    - by Red Gate Software BI Tools Team
    About a month ago, David mentioned an intern working in the BI Tools Team. That intern happens to be me! In five weeks’ time, I’ll start my second year of Computer Science at the University of Cambridge and be a full-time student again, but for the past eight weeks, I’ve been living a completely different life. As Jon mentioned before, the teams here at Red Gate are small and everyone (including the interns!) is responsible for the product as a whole. I’ve attended planning sessions, UX tests, daily meetings, and everything else a full-time member of the team would; I had as much say in where we would go next with the product as anyone; I was able to see that what I was doing was an important part of the product from the feedback we got in the UX tests. All these things almost made me forget that this is just an internship and not my full-time job. First steps at Red Gate Being based in Cambridge, Red Gate has many Cambridge university graduates working for them. They also hire some Cambridge undergraduates for internships each summer. With its popularity with university graduates and its great working environment, Red Gate has managed to build up a great reputation. When I thought of doing an internship here in Cambridge, Red Gate just seemed to be the obvious choice for my first real work experience. On my first day at Red Gate, David, the lead developer for SSAS Compare, helped me settle in and explained what I’d be doing. My task was to improve the user experience of displaying differences between MDX scripts by syntax highlighting, script formatting, and improving the difference identification in the first place. David suggested how I should approach the problem, but left all the details and design decisions to me. That was when I realised how much independence and responsibility I’d have. What I’ve done If you launch the latest version of SSAS Compare and drill down to an MDX script difference, you can see the changes that have been made. In earlier versions, you could only see the scripts in plain text on both sides — either in black or grey, depending on whether they were the same or not. However, you couldn’t see exactly where the scripts were different, which was especially annoying when the two scripts were large – as they often are. Furthermore, if parts of the two scripts were formatted differently, they seemed to be different but were actually the same, which caused even more confusion and made it difficult to see where the differences were. All these issues have been fixed now. The two scripts are automatically formatted by the tool so that if two things are syntactically equivalent, they look the same – including case differences in keywords! The actual difference is highlighted in grey, which makes them easy to spot. The difference identification has been improved as well, so two scripts aren’t identified as different if there’s just a difference in meaningless whitespace characters, or when you have “select” on one side and “SELECT” on the other. We also have syntax highlighting, which makes it easier to read the scripts. How I did it In order to do the formatting properly, we decided to parse the MDX scripts. After some investigation into parser builders, I decided to go with the GOLD Parser builder and the bsn-goldparser .NET engine. GOLD Parser builder provides a fairly nice GUI to write, build, and test grammar in. We also liked the idea of separating the grammar building from parsing a text. The bsn-goldparser is one of many .NET engines for GOLD, and although it doesn’t support the newest features of GOLD Parser, it has “the ability to map semantic action classes to terminals or reduction rules, so that a completely functional semantic AST can be created directly without intermediate token AST representation, and without the need for glue code.” That makes it much easier for us to change the implementation in our program when we change the grammar. As bsn-goldparser is open source, and I wanted some more features in it, I contributed two new features which have now been merged to the project. Unfortunately, there wasn’t an MDX grammar written for GOLD already, so I had to write it myself. I was referencing MSDN to get the formal grammar specification, but the specification was all over the place, so it wasn’t that easy to implement and find. We’re aware that we don’t yet fully support all valid MDX, so sometimes you’ll just see the MDX script difference displayed the old way. In that case, there is some grammar construct we don’t yet recognise. If you come across something SSAS Compare doesn’t recognise, we’d love to hear about it so we can add it to our grammar. When some MDX script gets parsed, a tree is produced. That tree can then be processed into a list of inlines which deal with the correct formatting and can be outputted to the screen. Doing all this has led me to many new technologies and projects I haven’t worked with before. This was my first experience with C# and Visual Studio, although I have done things in Java before. I have learnt how to unit test with NUnit, how to do dependency injection with Ninject, how to source-control code with SVN and Mercurial, how to build with TeamCity, how to use GOLD, and many other things. What’s coming next Sadly, my internship comes to an end this week, so there will be less development on MDX difference view for a while. But the team is going to work on marking the differences better and making it consistent with difference indication in the top part of comparison window, and will keep adding support for more MDX grammar so you can see the differences easily in every comparison you make. So long! And maybe I’ll see you next summer!

  • jQuery Ajax Error Handling – How To Show Custom Error Messages

    - by schnieds
    So you want to make your error feedback nice for your users…Kind of an ironic statement isn’t it? We obviously want to avoid errors if at all possible in our applications, but when errors do occur then we want to provide some nice feedback to our users. The worst thing that can happen is to blow up a huge server exception page when something goes wrong or equally bad is not providing any feedback at all and leaving the user in the dark. Although I do not recommend displaying actual .NET Framework exception messages or stack traces to the user in most instances; they are usually not helpful to the user and can be a security concern....

  • Count Email Address Domains

    - by BRADINO
    A quick tidbit I came up with today to count email addresses in a mysql database table grouping them by domain. So say for example you have a large list of subscribers and you want to see the breakdown of people who use Hotmail, Yahoo, Gmail, etc. SELECT COUNT( SUBSTRING_INDEX( `email` , '@', -1 ) ) AS `count` , SUBSTRING_INDEX( `email` , '@', -1 ) AS `domain` FROM `subscribers` WHERE `email` != '' GROUP BY `domain` ORDER BY `count` DESC This sql statement assumes that the table is called 'subscribers' and the column containing the email addresses is 'email'. Change these two values to match your table name and email address column name. mysql count email mysql count domain mysql split email mysql split domain

  • FNhibernate, GeneratedBy.HiLo, hibernate_unique_key etc.

    - by csetzkorn
    Hi, I have started using the s#arp architecture which uses FNhibernate and GeneratedBy.HiLo to generate primary keys (there is also table hibernate_unique_key). Apparently, this is recommended practise and I would like to stick with this. Now to my problem. I have used NHibernate and hbm mapping quite a bit and usually used identity columns for my primary keys. This allowed me to seed the database using SQL. Can I do this with the aforementioned setup (hibernate_unique_key table etc.). I need to do this as SQL insert is much more efficient than using NHibernate + C# to seed the db with a million entities. Any feedback would be very much appreciated. Thanks. Christian

  • subsonic.migrations and Oracle XE

    - by andrecarlucci
    Hello, Probably I'm doing something wrong but here it goes: I'm trying to create a database using subsonic.migrations in an OracleXE version 10.2.0.1.0. I have ODP v 10.2.0.2.20 installed. This is my app.config: <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <section name="SubSonicService" type="SubSonic.SubSonicSection, SubSonic" requirePermission="false"/> </configSections> <connectionStrings> <add name="test" connectionString="Data Source=XE; User Id=test; Password=test;"/> </connectionStrings> <SubSonicService defaultProvider="test"> <providers> <clear/> <add name="test" type="SubSonic.OracleDataProvider, SubSonic" connectionStringName="test" generatedNamespace="testdb"/> </providers> </SubSonicService> </configuration> And that's my first migration: public class Migration001_Init : Migration { public override void Up() { //Create the records table TableSchema.Table records = CreateTable("asdf"); records.AddColumn("RecordName"); } public override void Down() { DropTable("asdf"); } } When I run the sonic.exe, I get this exception: Setting ConfigPath: 'App.config' Building configuration from D:\Users\carlucci\Documents\Visual Studio 2008\Projects\Wum\Wum.Migration\App.config Adding connection to test ERROR: Trying to execute migrate Error Message: System.Data.OracleClient.OracleException: ORA-02253: especifica‡Æo de restri‡Æo nÆo permitida aqui at System.Data.OracleClient.OracleConnection.CheckError(OciErrorHandle errorHandle, Int32 rc) at System.Data.OracleClient.OracleCommand.Execute(OciStatementHandle statementHandle, CommandBehavior behavior, Boolean needRowid, OciRowidDescriptor& rowidDescriptor, ArrayList& resultParameterOrdinals) at System.Data.OracleClient.OracleCommand.ExecuteNonQueryInternal(Boolean needRowid, OciRowidDescriptor& rowidDescriptor) at System.Data.OracleClient.OracleCommand.ExecuteNonQuery() at SubSonic.OracleDataProvider.ExecuteQuery(QueryCommand qry) in D:\@SubSonic\SubSonic\SubSonic\DataProviders\OracleDataProvider.cs:line 350 at SubSonic.DataService.ExecuteQuery(QueryCommand cmd) in D:\@SubSonic\SubSonic\SubSonic\DataProviders\DataService.cs:line 544 at SubSonic.Migrations.Migrator.CreateSchemaInfo(String providerName) in D:\@SubSonic\SubSonic\SubSonic.Migrations\Migrator.cs:line 249 at SubSonic.Migrations.Migrator.GetCurrentVersion(String providerName) in D:\@SubSonic\SubSonic\SubSonic.Migrations\Migrator.cs:line 232 at SubSonic.Migrations.Migrator.Migrate(String providerName, String migrationDirectory, Nullable`1 toVersion) in D:\@SubSonic\SubSonic\SubSonic.Migrations\Migrator.cs:line 50 at SubSonic.SubCommander.Program.Migrate() in D:\@SubSonic\SubSonic\SubCommander\Program.cs:line 264 at SubSonic.SubCommander.Program.Main(String[] args) in D:\@SubSonic\SubSonic\SubCommander\Program.cs:line 90 Execution Time: 379ms What am I doing wrong? Thanks a lot for any help :) Andre Carlucci UPDATE: As pointed by Anton, the problem is the subsonic OracleSqlGenerator. It is trying to create the schema table using this sql: CREATE TABLE SubSonicSchemaInfo ( version int NOT NULL CONSTRAINT DF_SubSonicSchemaInfo_version DEFAULT (0) ) Which doesn't work on oracle. The correct sql would be: CREATE TABLE SubSonicSchemaInfo ( version int DEFAULT (0), constraint DF_SubSonicSchemaInfo_version primary key (version) ) The funny thing is that since this is the very first sql executed by subsonic migrations, NOBODY EVER TESTED it on oracle.

  • Modify the Event Log Source name for an SSIS package

    - by Paul Kohler
    I have an SQL Server integration Services (SSIS) package using the standard Event Log provider (yes, the event log! I know we can use SQL etc...) The default "Source" of the log events is "SQLISPackage100" but I want it to be something like "AppName" so that the errors are more visible between the different packages when viewing the event log (also for MOM use). Event Type: Error Event Source: SQLISPackage100 Event Category: None ... Description: Package "Foo" failed. I hope the answer is simple, I simply cannot find it, but does anyone know how to change the text of the Event Log Source name to something more meaningful? PK :-)

  • DAL without web2py

    - by Jay
    I am using web2py to power my web site. I decided to use the web2py DAL for a long running program that runs behind the site. This program does not seem to update its data or the database (sometimes). from gluon.sql import * from gluon.sql import SQLDB from locdb import * # contains # db = SQLDB("mysql://user/pw@localhost/mydb", pool_size=10) # db.define_table('orders', Field('status', 'integer'), Field('item', 'string'), # migrate='orders.table') orderid = 20 # there is row with id == 20 in table orders #when I do db(db.orders.id==orderid).update(status=6703) db.commit() It does not update the database, and a select on orders with this id, shows the correct data. In some circumstances a "db.rollback()" after a commit seems to help. Very strange to say the least. Have you seen this, more importantly do you know the solution? Jay

  • Grails GORM (Hibernate) query

    - by bsreekanth
    Hello, I'm trying to do the below sql statement in GORM select * from table1 where table1.x not in (select x from table 2 where y='something'); so, I have two tables, and needs to find the entries from table 1 which are not in table 2. In Grails def xx= table2.findByY('something') def c = table1.createCriteria() def result= c.list { not ( in('x', xx) ) } the syntax is wrong, and I'm not sure how to simulate not in sql logic. As a learning point, if someone can also tell me why minus (-) operator in grails/groovy doesn't work with list. I tried getting x and y seperately, and doing x.minus(y), but it doesn't change the list. I saw an explanation at http://stackoverflow.com/questions/1754576/groovy-on-grails-list-not-working , but I would expect the list defined are local. thank you so much.

  • MSSQL EXPRESS 2008 Stored Procedure execution time spikes periodically

    - by user156241
    I have a big stored procedure on a MSSQL 2008 Express SP2 database that gets run about every 200 ms. Normal execution time is about 50ms. What I am seeing is large inconsistencies in this run time. It will execute for while, say 50-100 times at 40-60ms which is expected, then seemingly at random the same stored procedure will take way longer, say 900ms or 1.5 seconds to run. Sometimes more than one call of the same procedure in a row will take longer too. It appears that something is causing sql server to slow down dramatically every minute or so, but I can't figure out what. There is no timing pattern between the occurences. I have the same setup on two different computers, one of which is a clean XP Pro load with no virus checking and nothing installed except SQL server. Also, The recovery options for all the databases are set to "Simple".

  • How should I use this SetSPN command when installing SharePoint

    - by Paul Rowland
    In the SharePoint install document I have it says, If you use a domain user account for the SQL Server service account, you must make sure that a valid service principal name (SPN) for that account and instance of SQL Server on their database server exists in their environment. This is the case regardless of whether you use NTLM or Kerberos authentication for Office SharePoint Server 2007. You must configure the SPN for that account in the domain using the Setspn.exe command-line tool. Setspn.exe is installed by default on computers running Windows Server 2008. Run the following command on a computer that is joined to the same domain as the user/service account. setspn -a <http/<farmclusterdnsname> <serviceaccountname> What should the parameters be in this case? I guess the serviceaccountname would be 'domain\username' not sure what the first parameter should be though. This is the technet link for SetSPN.

    Hi, I am using sql server integration services(SSIS) in sql server business intelligent devolopment studio. I need to do a task --that is. I have to read from a source database and put it into a destination flat file.But the same time the source databse should be configurable. That means in the Oledbconnection manager connection string should change dynamically.this connection string should be taking from a configuration/xml/flat file. I read that i can use varaibles and expressions to change the connection string dynamically.But how do i read connection string value from a config/xml/flat file and set the variable? This part i am unable to do.Or is this the right way to achieve this.. Can we add web.config files to ssis project.? I am new to SSIs. Please provide some help with examles etc. and this is quiet urgent for me. Thanks SNA.

    This is probably a simple question to answer but I just can't figure it out. I have a "Company" class with a many-to-one to "Address" which has a many to one to a composite id in "City".

  • Backup options in SharePoint 2007

    - by sreejukg
    It is very important to make sure the server farm backup is taking properly, making sure that in case of any disaster, the administrator has the latest backup that can be used to restore. This articles addresses some of the options available for backup/restore in SharePoint 2007 Backup There are two options that can be utilized to take backup of SharePoint sites. Using SharePoint Central Administration website Using SharePoint central administration website, you can do backup/restore from user interface. Using central administration website you can back up the following · Server farm · Web application · Content databases Follow these steps to take backup of the server farm using central administration 1. Open Central administration website 2. Navigate to Operations -> Backup and Restore -> Perform a backup 3. Here you will have options to choose the item to back up. Select Farm (the top most item in the list) 4. Once you select the items to backup, click on “Continue to backup options” 5. Select “Full” as type of backup. 6. In the backup file location, enter the path where you need to store the backup. The path should be according to the UNC, for e.g. for c drive you may use \\server\c$\mybackupFolder 7. Click ok 8. Now you will be redirected to Backup and Restore Status page. This page shows the progress for the backup operation. You can use the refresh button to update the status of backup(this page will automatically refresh in every 30 seconds). Once completed you can find the files in the specified folder. Using STSADM website SharePoint comes with a STSADM command line tool. STSADM provides lot of administrative operations that can be performed on SharePoint 2007 sites. You can find STSADM command from the following location C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin (You may change the drive letter according to your installation) STSADM provides a method for performing the Office SharePoint Server 2007 administration tasks at the command line or by using batch files or scripts. STSADM provides access to operations not available by using the Central Administration site The general syntax for STSADM is as follows STSADM -operation Operation Name –parameter1 value1 –parameter2 value2 ……….. Using STSADM you can back up the following · Server farm · Web application · Content databases To perform any STSADM, operation you need to be a member of administrators group. Follow these steps to take backup of SharePoint server farm using STSADM tool. Note: make sure you are logged in to the computer where central administration website is installed. 1. Open the Command prompt (You should run command prompt with administrator privileges) 2. Change the working directory to C:\Program Files\Common Files\Microsoft shared\web server extensions\12\bin 3. Enter the command, then press enter Stsadm –o backup -directory <UNC path> -backupmethod full 4. You will get success / failure message once the command finishes. How to schedule the backup There is no option to schedule a backup using central administration site. Also there is no operation provided by STSADM to automate the backup. The farm administrators need to take backup in regular intervals. To achieve this, you can write a batch file that includes STSADM command to take full backup of the server. This batch file can be scheduled using windows task scheduler to execute in certain intervals. Sample of the batch file 1. Open notepad(or any other text editor) 2. Enter the following commands @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm.exe -o backup -directory "<\backup>" -backupmethod full echo completed 3. Save the file with .bat extension You can schedule this batch file as you require. Other Options Using STSADM tool, you will be able to take backup for individual site collection. The syntax for this is stsadm -o backup -url <URL name for site collection> -filename <file name> [-overwrite] The explanations for the parameters are as follows. -url The url of the site collection you need to backup -filename The name of the backup file. E.g. c:\backup.bak -overwrite optional. Indicates if the filename specified exists, whether to overwrite or not. If you are creating the batch file for scheduling the backup for a site collection, you may need to specify the backup filename automatically created. It is an option that you can generate the filename with date so that you can keep backup for each day. e.g. The following commands can be utilized create a site collection backup. @echo off echo =============================================================== echo Back up the farm to <C:\backup> echo =============================================================== echo =============================================================== echo getting todays date to a variable echo =============================================================== @For /F "tokens=1,2,3 delims=/ " %%A in (‘Date /t’) do @( Set Day=%%A Set Month=%%B Set Year=%%C Set todayDate=%%C%%B%%A ) cd %COMMONPROGRAMFILES%\Microsoft Shared\web server extensions\12\BIN @echo off stsadm -o backup -url <sitecollection url> -filename \\ServerName\ShareName\Backup_%todayDate%.bak -overwrite echo completed To read more about backup STSADM operation, read this http://technet.microsoft.com/en-us/library/cc263441.aspx
