sql server - Where/How do I handle different connection types using Repository Pattern with ADO.Net? -

-

I'm new to the repository pattern, but building a repository to connect to two different database types I have those who have the same data structure.

  1. I will be connected to SQL Server 2005 and db2 (on iSeries)

    / li>

  2. I am using the repository in a WPF application.
  3. Although I want to use the unit framework, I can not. That's because IBM has imposed a good charge of $ 11,000 for a product called DB2 Connect, which will then give me access to my datacontext. Due to budget constraints, I am using ADOnate and using IDBCX interface.
  4. Why am I using two separate databases 1) Political, 2) Because our ERP system is based on AS-400 is very limited so I have to download my data to SQL Server and 3 ) Political

I have discussed all the tutorials on opening the connection within the call to the GetRecords () method. However, it is limiting me to a database.

  1. So, should I pass my connection object into my GetRecords method ?: GetRecords (MyIDbConnection)? It seems to restrict me if I decide to use XML (for whatever reason.)

  2. Within my GetRecords method, call me from the app needed. To get config connection string? Will this limit me if this repository is compiled in a .dll that does not have any app? Configure?

  3. Should I give a connection through Constructor instead?

  4. Can I use a data adapter?

Please advise.

Thank you.

You can use the pattern to provide a general way for the repository to be combined with the repository pattern You may want to consider communicating with the Data Access Layer. The gateway will provide a standard, platform-agnostic interface that does not require a repository to know something about the data source and its related APIs. You can present an example of a gateway in your repository using the Data Framework. This will help you control which types of gateways are transported through the repository of your central contents through the configuration strategy.

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
