  • Data sync solution?

    - by user321088
    For some security issues I'm in an envorinment where third party apps can't access my DB. For this reason I should have some service/tool/script (dunno what yet... i'm open to the best option, still reading to see what I'm gonna do...) which enables me to generate on a regular basis(daily, weekly, monthly) some csv file with all new/modified records for a certain application. I should be able to automate this process and also export at any time a new file. So it should keep track for each application which records he still needs. Each application will need some data in some other format (csv/xls/sql), also some fields will be needed for some application and some aren't... It should be fairly flexible... What is the best option for me? Creating some custom tables for each application? Based on that extracting modified data?

  • Better languages than SQL for stored procedures

    - by Ken Paul
    I'm getting increasingly frustrated with the limitations and verbosity required to actually commit some business logic to stored procedures, using languages such as Transact-SQL or PL/SQL. I would love to convert some current databases to Oracle and take advantage of its support for Java stored procedures, but that option is not available at the moment. What alternatives would you recommend in the way of databases that support stored procedures in other languages?

  • Populate an SQL Server 2k8 with Oracle Loader files

    - by Techpriester
    Hi folks. Here's the problem: I have a project that needs to be migrated to Microsoft SQL Server 2008. We have data in text files for the Oracle SQL Loader and now we need to get that data into the SQL Server DB. I could write a program that converts everything into INSERT statements but there has to be a more comfortable way to so this. Any suggestions? PS: I don't think my company wants to buy additional Software to do this job so that's out.

  • How to get a list of items when using cassandra

    - by Blankman
    When using a nosql type datastore like Cassandra, how would you return a result set based on a column? e.g. SELECT * FROM Articles WHERE category='blah' ORDER BY datetime DESC is this something that you would store in a sql db and then pull the data from cassandra? Or can cassandra handle this type of query? (assuming millions of rows in a db) From what I understand, cassandra is great at key based lookups, confused if it can and should be used for getting a list of data back and paging that data also (and if it is highly performant)

  • MS Analysis Services OLAP API for Python

    - by Kaloyan Todorov
    I am looking for a way to connect to a MS Analysis Services OLAP cube, run MDX queries, and pull the results into Python. In other words, exactly what Excel does. Is there a solution in Python that would let me do that? Someone with a similar question going pointed to Django's ORM. As much as I like the framework, this is not what I am looking for. I am also not looking for a way to pull rows and aggregate them -- that's what Analysis Services is for in the first place. Ideas? Thanks.

  • Need help with ConnectionString value in C#

    - by SzamDev
    Hi I have an idea and I want to apply it to my Application (C# .NET). When we connect to a DB (MS SQL Server 2008) in VS 2008, the ConnectionString saved in the Application Setting and it's a static varriable (no one can edit it unless you edit it inside VS 2008). I want a way to let my Application search for MS SQL Server and save it to Application Setting and use it to connect to my DB Programmatically. When my application start, the first thing to do is checking the ConnectionString if vaild, NOT Empty and test connection to MS SQL Server Successfully so if there is a proplem I think to show a window form to let the user enter some data like username and password for MS SQL Server 2008 Is there any way to do it?

  • IP address detection for geo-location or MAC address much secure?

    - by SuperRomia
    Recent study many websites are using geo-location technology on their Websites. I'm planning to implement one website which can be detect the web visitor more accurate. An found that Mozilla is using some kind of detect MAC address technology in their Geo-Location web service. Is it violate some privacy issue? I believe most of Geo-location service providers only offer country to city level. But the Mac address detection enable to locate the web visitors' location more correctly than using IP address detection. If detect the MAC address is not practical, which geo-location service provider is offering more accurate data to detect my Website visitor around the world?

  • RavenDB-Embedded Unstable In Cooperation With ASP .Net Web API Using 2-Tier Architecture

    - by Mohsen Alikhani
    My application is used RavenDB-Embedded Unstable 1.2.2127 that it's intracted with ASP .Net Web API in the separated assemblies. When I use "UseEmbeddedHttpServer = true" on the document store, first time I send a request to RavenDB, it executes properly but when I try for the second time my application displays Raven Studio. However, if UseEmbeddedServer setting be removed then my application will be running without any problems. My RavenDB is configured with the following codes in data tier : this.documentStore = new EmbeddableDocumentStore { ConnectionStringName = "RavenDB", UseEmbeddedHttpServer = true } and implementation of Web.config have these settings in the service tier : <connectionStrings> <add name="RavenDB" connectionString="~\App_Data\RavenDatabase" /> </connectionStrings> Is there a setting I missed?

  • Vehicle 2 Vehicle Communication Questions

    - by pinnacler
    I have a rare opportunity to meet the man in charge of implementing vehicle 2 vehicle communication for the US Department of Transportation with 2 others in a few hours. Do YOU have any questions for him? I know this is a little outside the normal, but this is a 'reverse' thread and I felt he has some great knowledge on the subject that I want to share with this community. I'll post his answers later today to his questions. Ask about V2V implementation, privacy issues, use cases, or if you've thought of a great way to use V2V and want me to share it with him, he can at least think about it. He is in charge of panel that creates the standard. Or anything else...

  • mongodb php finding a subobject and removing it, $inc other subobject

    - by Mark
    I'm trying to delete the subobject 'apples' from my documents and update the 'fruitInventory' property, decrease by the amount of apples. I'm confused on how to proceed, should I use dot notation or do a full text search for apples? I don't know if this matters but you can assume apples will always be in field 1. // Document 1 { "1": { "apples": 3, "fruitInventory": 21, "oranges": 12, "kiwis": 3, "lemons": 3 }, "2": { "bananas": 4, "fruitInventory": 12, "oranges": 8, }, "_id": "1" } // Document 2 { "1": { "apples": 5, "fruitInventory": 10, "oranges": 2, "pears": 3 }, "2": { "bananas": 4, "fruitInventory": 6, "cherries": 2, }, "_id": "2" } Result should be like this: // Document 1 { "1": { "fruitInventory": 18, "oranges": 12, "kiwis": 3, "lemons": "3" }, "2": { "bananas": 4, "fruitInventory": 12, "oranges": 8, }, "_id": "1" } // Document 2 { "1": { "fruitInventory": 5, "oranges": "2", "pears": "3" }, "2": { "bananas": 4, "fruitInventory": 6, "cherries": 2, }, "_id": "2" } Thanks in advance for your help.

  • Table-level diff and sync procedure for T-SQL

    - by Ville Koskinen
    I'm interested in T-SQL source code for synchronizing a table (or perhaps a subset of it) with data from another similar table. The two tables could contain any variables, for example I could have base table source table ========== ============ id val id val ---------- ------------ 0 1 0 3 1 2 1 2 2 3 3 4 or base table source table =================== ================== key val1 val2 key val1 val2 ------------------- ------------------ A 1 0 A 1 1 B 2 1 C 2 2 C 3 3 E 4 0 or any two tables containing similar columns with similar names. I'd like to be able to check that the two tables have matching columns: the source table has exactly the same columns as the base table and the datatypes match make a diff from the base table to the source table do the necessary updates, deletes and inserts to change the data in the base table to correspond the source table optionally limit the diff to a subset of the base table, preferrably with a stored procedure. Has anyone written a stored proc for this or could you point to a source?

  • Codeigniter: Combining activeRecord with manual queries?

    - by Industrial
    Hi everybody, I've though a bit about the activerecord vs. manual queries in Codeigniter. ActiveRecord is awesome when it's all about standard queries and holds development time really low. However, when there's a need to add some complexity to the queries, the ActiveRecord gets quite complicated to work with. Sub queries or complex joins gives atleast me a lot of headache. Since the current "$this-db-query" -call immediately executes the set query, it can't be combined with normal activeRecord calls. So, what can I do to combine the two methods? Thanks!

  • Django ORM and PostgreSQL connection limits

    - by bennylope
    I'm running a Django project on Postgresql 8.1.21 (using Django 1.1.1, Python2.5, psycopg2, Apache2 with mod_wsgi 3.2). We've recently encountered this lovely error: OperationalError: FATAL: connection limit exceeded for non-superusers I'm not the first person to run up against this. There's a lot of discussion about this error, specifically with psycopg, but much of it centers on older versions of Django and/or offer solutions involving edits to code in Django itself. I've yet to find a succinct explanation of how to solve the problem of the Django ORM (or psycopg, whichever is really responsible, in this case) leaving open Postgre connections. Will simply adding connection.close() at the end of every view solve this problem? Better yet, has anyone conclusively solved this problem and kicked this error's ass?

  • Elegantly handling constraint violations in EJB/JPA environment?

    - by hallidave
    I'm working with EJB and JPA on a Glassfish v3 app server. I have an Entity class where I'm forcing one of the fields to be unique with a @Column annotation. @Entity public class MyEntity implements Serializable { private String uniqueName; public MyEntity() { } @Column(unique = true, nullable = false) public String getUniqueName() { return uniqueName; } public void setUniqueName(String uniqueName) { this.uniqueName = uniqueName; } } When I try to persist an object with this field set to a non-unique value I get an exception (as expected) when the transaction managed by the EJB container commits. I have two problems I'd like to solve: 1) The exception I get is the unhelpful "javax.ejb.EJBException: Transaction aborted". If I recursively call getCause() enough times, I eventually reach the more useful "java.sql.SQLIntegrityConstraintViolationException", but this exception is part of the EclipseLink implementation and I'm not really comfortable relying on it's existence. Is there a better way to get detailed error information with JPA? 2) The EJB container insists on logging this error even though I catch it and handle it. Is there a better way to handle this error which will stop Glassfish from cluttering up my logs with useless exception information? Thanks.
