  • Oracle Cursor and JDBC ODBC

    - by BeginnerAmongBeginners
    I have some procedures to execute in the database that has an OUT REFCURSOR parameter. When I am connecting with the JDBC thin client, everything works fine. However, if I were to change the connection string to refer to the ODBC data source pointing to the same database, those procedures will fail. The procedures that do not use an OUT REFCURSOR will still work fine though. Is this situation the result of an error on my part or expected?

  • applescript for sqlite

    - by user1212108
    I have a Windows app called via Shell from MS Word that reads and writes to Sqlite. I'm porting it to Mac. On windows I have a batch file: SQLite3.exe pathtodb\databasename <sqlitecommands.txt This batch calls the Sqlite command line program, attachs the database, and reads the command from sqlitecommands.txt. The sqlitecommands is dynamically modified(by Word VBA) to read (Select) Write (Update) to/from the database. What is the format of an applescript to do the same thing in Mac OSX?

  • Ignore first line on csv parse Rails

    - by Jack

  • Sending messages between two Python servers

    - by Will
    I have two servers - one Django, the other likely to be written in Python - and one is putting 'tasks' into a database and another is processing these tasks. They share a database, but I want the processor to react quickly to new tasks rather than polling periodically. Are there any straightforward ways for two Python servers to talk to one another, or does the task processor have to have web-hooks or something? It feels there ought to be a blessed way to do this...

  • Alternatives of Datatable

    - by mavera
    In my web application, I have a dynamic query that returns huge data to datatable, and this query is often recalled with different parameters. So database is exhausted. I want to get all record with no parameters to an object, and perform queries (may be with linq) on this object. So database will not be exthausted. Which objects can be used instead of datatable?

  • Where does the AccountController in Asp.Net MVC 2 store its data?

    - by JLago
    I'm creating a website using ASP.NET MVC 2 and I'm thinking of using the default AccountController and Views to take care of the Users. The only problem is that, for all the rest, I'm using a Postgres database. Is there a way to link The account controller to a User class defined by me? I'm using Nhibernate to connect to the database, so I'll have a User class with whatever fields necessary. Thanks very much.

  • Stored Procedure could not be found

    - by Beatles1692
    We use SQL server 2008 as our RDBMS and we have a database that has a different user rather than dbo as its owner. The problem is in one machine a stored procedure can not run unless its owner is mentioned. If we connect to our database using this user and try to execute the following : exec ourSP we get a "could not find ourSP" error but this works fine: exec user.ourSP Does anybody knows what can lead to such a strange behavior?

  • Entity Framework 4 omits some associations during model generation

    - by kzen
    After creating an EF4 model from a SQL Server database I noticed that all the relationships of my Users table were not imported into the model as associations. All the other relationships were imported fine. My Users table has a PK userId which is a char(7) field and it is integrated into several other tables in the database as an FK but for some reason EF4 does not import these relationships as associations during the model generation process... Does anyone have any ideas why this would be happening?

  • Managing trace files on Sql Server 2005

    - by Sophtware
    I need to manage the trace files for a database on Sql Server 2005 Express Edition. The C2 audit logging is turned on for the database, and the files that it's creating are eating up a lot of space. Can this be done from within Sql Server, or do I need to write a service to monitor these files and take the appropriate actions? I found the [master].[sys].[trace] table with the trace file properties. Does anyone know the meaning of the fields in this table?

    - by Andrei Tanasescu
    I am building a c# - linq - sql server winforms/asp.net application, accessing a database.

What design patterns/ best practices are available for the following use cases - inserting/updating a new object - searching for an object - loading a bunch of related data into a sort of "presentation" object that could be displayed by various views ?

  • SQL Design Question regarding schema and if Name value pair is the best solution

    - by Aur
    I am having a small problem trying to decide on database schema for a current project. I am by no means a DBA. The application parses through a file based on user input and enters that data in the database. The number of fields that can be parsed is between 1 and 42 at the current moment. The current design of the database is entirely flat with there being 42 columns; some have repeated columns such as address1, address2, address3, etc... This says that I should normalize the data. However, data integrity is not needed at this moment and the way the data is shaped I'm looking at several joins. Not a bad thing but the data is still in a 1 to 1 relationship and I still see a lot of empty fields per row. So my concerns are that this does not allow the database or the application to be very extendable. If they want to add more fields to be parsed (which they do) than I'd need to create another table and add another foreign key to the linking table. The third option is I have a table where the fields are defined and a table for each record. So what I was thinking is to make a table that stores the value and then links to those two tables. The problem is I can picture the size of that table growing large depending on the input size. If someone gives me a file with 300,000 records than 300,000 x 40 = 12 million so I have some reservations. However I think if I get to that point than I should be happy it is being used. This option also allows for more custom displaying of information albeit a bit more work but little rework even if you add more fields. So the problem boils down to: 1. Current design is a flat file which makes extending it hard and it is not normalized. 2. Normalize the tables although no real benefits for the moment but requirements change. 3. Normalize it down into the name value pair and hope size doesn't hurt. There are a large number of inserts, updates, and selects against that table. So performance is a worry but I believe the saying is design now, performance testing later? I'm probably just missing something practical so any comments would be appreciated even if it’s a quick sanity check. Thank you for your time.

  • How does timezone really work in relation to PHP and MYSQL?

    - by Rick
    I am getting very strange results in terms of timezones. I am currently using Wordpress and everytime I register a new user, I see the wrong datetime in the database. Ok so I am suspecting it is picking up the server time. So then I then set in php.ini to have date.timezone = "America/Los_Angeles" but again the time is still not correct in the database...And yes I have also set the timezone in Wordpress correctly. So how can this be done?
