  • Database Mirroring of SQL server

    - by jbp117
    I have two databases that are mirrored to another server using database mirroring. The mirror server has to be down for some reason for few days. Now the production server is having principal databases in (PRINCIPAL/DISCONNECTED) State. Clients can access those databases. So what happens when they keep on adding data to these databases?? Will the data get committed or waits till the mirror comes up?

  • Automatic incremental SQL Script generation for incremental, nightly builds when using Team Build in

    - by Steve Johnson
    hi all, hope that everybody here is OK. We are using VS 2008 as development tool, TFS 2008 as version control as well as build automation. Some of our developer use dbpro for databases changes and some use SQL Server management studio. I am trying to automate build for Web Application built using C# and VB.Net. Our scenario is such that we have a central database to which our web application connects. Whenever we supply our clients with a new functionality or a bug fix, we supply them incremental builds. The SQL script is checked into source control for every incremental build when they have made and tested there changes on our central DB Server. I want to generate Differential script that can be run at the client as an incremental update script. Now to come about it is a problem. Sometimes our developers tend to forget the database change-sets and the script in the source control is missing an SP or a two. Also, sometimes we need to insert default data into some of the tables that have strict stringent values and not test values. Like a table that contains Services provided by the panel, we add a new service name, signature, credentials and service address, etc etc in the ServiceTable. Besides this many other tables may have test data that may not be needed. If we use DataCompare, it will generate changeset for required data (important for client to enable certain services) and our test data that was added to the database as a result of our testing of the functionality or bug fix. Currently i am using SQLSchemaCompareTask (from Visual Studio 2008 Team Database Professional Power Tools API) in the TFSBuild.proj file of the build definition for TFS 2008. Using SQLSchemaCompareTask, the script generated contains database names like [dbo]. etc which are not desired as the script fails when run against SQL Server 2000 databses (Some of our client still use SQL Server 2000) databases as teh backend of the application. Also default data can't be generated by this process. To overcome this problem, i have to come up with a solution that can compare databases and generate script automatically that does not have to be manually reviewed again before being sent to the client. Please suggest effective methodology of such SQL script generation and suggest whether two different databases may be used or something ? Is there any toolkit or api that can enable build automation for SQL Server databases? Thank you all. Regards Steve

  • Best Role-Based Access Control (RBAC) database model

    - by jhs
    What is the best database schema to track role-based access controls for a web application? I am using Rails, but the RBAC plugin linked by Google looks unmaintained (only 300 commits to SVN; latest was almost a year ago). The concept is simple enough to implement from scratch, yet complex and important enough that it's worth getting right. So how do others architect and implement their RBAC model?

  • Visual Studio Database Edition (DataDude) error numbers?

    - by E. Wilson
    Is there a list somewhere of all the output message numbers from VSDB Depolyments (VsDbCmd.exe from Visual Studio Database Edition)? For example, TSD01268 = normal action successful TSD01236 = missing referenced file (fail) TSD01237 = missing script file (fail) TSD00566 = deployment script generated to _ The way we are wrapping calls to VsDbCmd.exe means catching the %errorlevel% isn't always reliable so we also like to check the output for certain error conditions. It would be nice to see a consolidated list somewhere.

  • Idea for a user friendly/non technical RAD tool for performing queries and reports on Database

    - by pierocampanelli
    I am investigating for a tool that allows a user to perform in a user friendly way queries to database for extracting datas and creating reports. Primary requirement is that we can't know queries users are going to do. So we need to design a flexible UI allowing them to specify in a non technical way. My question is: do you know any tool that does something similar? Have you some inspiring user interface?

  • Reading Foxpro database date field using PHP

    - by Bill Yang
    I've wrote a PHP script to export a Foxpro database to other formats by using ADODB (http://phplens.com/lens/adodb) library to access Foxpro OLE DB provider. Everything worked fine except the date fields are mangled and become like these: 11/17-/2-00 3/4/-20-08 By comparing to actual data I can guess that it is probably in the format of MM/DD/YYYY or m/d/YYYY. How can I properly export the date field?

  • translate database fields with rails

    - by fursie
    hi I know about the built-in I18n in Rails, but how can I select a database field per locale? My model structure is something like this: title #default (englisch) title_de #(german) title_it #(italian) In my template I want to be able to write only <%= @model.title %> and should get the value in the right language. Is there a plugin or a solution to use different fields per different locale settings with a structure like mine?

  • How do you save compare options in Visual Studio 2010 > SQL 2012 Database Project

    - by profMamba
    Been using the new SQL 2012 Data Tools SQL Server Database Project in VS 2010. Every time we do a schema compare we have to set the options for the current compare. This does not seem to be tied back to the global compare options you can set in Tools Options. Does anybody know where to set the 'new' global compare options. NOTE: This is the new SQL 2012 compare from Data Tools, and not the old 2005/2008 compare that comes standard with Studio 2010.

  • Using perl to parse a file and insert specific values into a database

    - by Sean
    Disclaimer: I'm a newbie at scripting in perl, this is partially a learning exercise (but still a project for work). Also, I have a much stronger grasp on shell scripting, so my examples will likely be formatted in that mindset (but I would like to create them in perl). Sorry in advance for my verbosity, I want to make sure I am at least marginally clear in getting my point across I have a text file (a reference guide) that is a Word document converted to text then swapped from Windows to UNIX format in Notepad++. The file is uniform in that each section of the file had the same fields/formatting/tables. What I have planned to do, in a basic way is grab each section, keyed by unique batch job names and place all of the values into a database (or maybe just an excel file) so all the fields can be searched/edited for each job much easier than in the word file and possibly create a web interface later on. So what I want to do is grab each section by doing something like: sed -n '/job_name_1_regex/,/job_name_2_regex/' file.txt --how would this be formatted within a perl script? (grab the section in total, then break it down further from there) To read the file in the script I have open FORMAT_FILE, 'test_format.txt'; and then use foreach $line (<FORMAT_FILE>) to parse the file line by line. --is there a better way? My next problem is that since I converted from a word doc with tables, which looks like: Table Heading 1 Table Heading 2 Heading 1/Value 1 Heading 2/Value 1 Heading 1/Value 2 Heading 2/Value 2 but the text file it looks like: Table Heading 1 Table Heading 2Heading 1/Value 1Heading 1/Value 2Heading 2/Value 1Heading 2/Value 2 So I want to have "Heading 1" and "Heading 2" as a columns name and then put the respective values there. I just am not sure how to get the values in relation to the heading from the text file. The values of Heading 1 will always be the line number of Heading 1 plus 2 (Heading 1, Heading 2, Values for heading 1). I know this can be done in awk/sed pretty easily, just not sure how to address it inside a perl script. After I have all the right values and such, linking it up to a database may be an issue as well, I haven't started looking at the way perl interacts with DBs yet. Sorry if this is a bit scatterbrained...it's still not fully formed in my head.
