Sorting is wrong with Entity Framework for oracle

Hi,
I've downloaded the Entity Framework for Oracle beta and I found a bug. It's easy to repro:
- Create a model with a simple table
- Create a dynamic data web app
- display the content of your table and try to sort
-> the sql generated is wrong and only sorts on the currently displayed rows and not the entire data.
Did anyone else notice that?

Before ODP.NET beta with EF was available I was working with OracleEFProvider from CodePlex (sample alpha version but works with VS2010).
I found the same issue there. Since I had a source code I managed to find the solution.
In class which implemented the base class DbExpressionVisitor there was a method: public override ISqlFragment Visit(DbSkipExpression e)
I had to add sort clause AFTER visiting the expression (which was done too early in previous code).
As the main idea of DbExpressionVisitor should be the same in case of Oracle provider, this can be the reason of improper sorting in queries with paging.

Want to use the Entity Framework for Oracle

Currently our web applications are installed on Windows 2003 Server, IIS 6.0. Yes, this seems like the dark ages...years behind. They have an older version of the Oracle Client on the machine (11.0.1). This version does not support Oracle.DataAccess 4.x. .NET Framework 4.0 is installed on the Windows 2003 server. This version also does not support the Entity Framework.
However, my development environment does not have any Oracle Client installed. I am just using the latest version of ODAC/ODP.NET with Visual Studio 2010. I am able to create apps locally with the Entity Framework but unfortunately cannot get them to work on the server because there of the older Oracle Client on that machine. Also there are approx. 50 applications on that server that are accessing this old version of OracleDataAccess 2.116.0 with references hard coded in the web.config. What's the best practice for dealing with legacy applications that are accessing older versions of Oracle?
In short, what do I need to do in order to upgrade to the version of Oracle that will support the Entity Framework while still supporting legacy apps? Do I go for an Oracle Client upgrade or I just merely get the latest version of ODAC/ODP.NET installed on that server?
Thanks!

What I would probably like to do is somehow set the dll directory to my local bin directory and just put all the .dlls for the most recent ODP.NET in my app and leave the existing applications as they are until I can migrate them.
I've seen examples of this but doesn't seem to work for me.You can do that by having both Oracle clients installed, and using the DLLPath configuration option to force the applications to use the one you want.
That said, the next version of the managed client is going to support working in Entity Framework, and that is just an assembly you can include in the project with no Oracle installation at all. So really, the best answer is going to be to use that once they release it.
(Also - most of the time something compiled for Oracle 11.x will work in 11.2.0.3 without doing anything. The 11.2.0.3 installer adds binding redirects to itself from older versions, provided you were loading from the GAC.)

Problem with Microsoft ODBC for Oracle Driver

I tried to import table in MS Access with Microsoft ODBC for Oracle Driver, but a msg error appeared:
"Reserved error (-7776); there is no message for this error"
I think the problem is about Microsoft Jet, but i'm not sure.
Does anybody already had this problem?

Given that you're using a Microsoft front-end and a Microsoft ODBC driver, I'm not sure how much help you'll find on this forum. You could try substituting the Oracle ODBC driver to see if that improves anything.

Good or Bad: Repository pattern with Entity framework??

Suggestions about not to use enttity framework because:
1) entity framework is itself a Repository pattern
2) So, what the use of having one more repository pattern over an exisitng repositroy pattern (i.e Entity framework)
Please suggest.
Thanks in advance!!

I've used both nHibernate and the Entity Framework 6 and nHibernate wins hands down as the best orm, despite it's learning curve. ORMs can be massive timesavers as you don't end up writing boiler plate db access code.
I used 3 different versions on nHibernate over the years. I didn't paticulalry care for any version of nHibernate. I much prefer EF over nHibernate any day of the week, month or year.
Unlike the previous responder I disagree with testability, each repository should have it's own interface. And if implemented correctly it can save tones of time as you need only mock one or two repository methods rather than 10s or 100s of database
gateway call using one class per table.
What? Like a DAO can't have an interface, which is just as testable as any repository pattern using an interface when using a test harnerss and testproject to test the DAO? And one has to go beyond some generic repository pattern in
unit, functional and intergation testing when it comes to data access.
Unlike you, I want complete control of the object all aspects of it even in its usage of other DAO(s) that could or would be used, which the repository pattern doesn't cut it for me.
Like I said, I'll take EF over nHibernate, which is much like talking MS SQL Server over Oracle with Oracle being a PITA to work with it.

SUNWsprox package with solaris 10 for Oracle 10g Installation....

Hi
I am in problem with a Solaris 10 package "SUNWsprox - Sun workshop Bundled 64-bit make library" for Oracle 10g Installation. I checked the CDs (In the /.../products) but did't found this packege. Can any one tell me please can I go without this package or where I found this package...Please Its very URGENT for me....
Thanks
Mohammed Tanvir

Hi...
I had the same issue, but found out that the SUNWsprox was replaced by SUNWsprot. The OUI 10.1 Release 2 will 'pass' as the doco in the Oracle quick install guide is wrong (as well as 10g Application Server).
The only way to lay a 10g Release database on Solaris 10 is to lay the software doen only, then cd in the .../bin directory, step your Rdbms ORACLE_HOME, ORACLE_SID, LD_LIBRARY_PATH and of course the DISPLAY (is X-windowing into the server), and run dbca manually. Oracle 10g is a bit buggy.

Where are the data-binding frameworks for Oracle Objects?

Oracle offers a few different options for data-binding frameworks to Oracle relational data. Amongst them they include TopLink and the Oracle Application Development Framework (ADF)in JDeveloper 10G. J2EE also offers the EJB standard framework. Both of the Oracle data-binding frameworks appear to work well with relational data but fail miserably when one tries to work with a fully fledged Oracle Object-Relational schema. I have spend much time with ADF but have not been able to create successful bindings to Objects with nested complex objects (such as a 2-level nested object) or objects containing nested tables. TopLink will not even touch Object tables.
Have other people being more successful with this? Do we have to implement our own data binding framework? Does Oracle plan on improving these frameworks to fully support Oracle Objects?

TopLink Runtime supports both fully fledged OX mappings and nested complex objects. These mappings can be setup in the code.
TopLink ADF design time however currently does not have support for OX mappings.
Hope this helps,

What's wrong with my code for comparing date retreived from db and sysdate?

Hi all,
I need to retrive date from the DB and compare it to system date.i have posted the code below.i get java.sql.SQL Exception:Io exception:Socket closed.
What's wrong with the code?please help me.Thanks in advance.
public boolean date() throws IOException, SQLException {
Connection con1;
long millis = System.currentTimeMillis();
Timestamp timestamp = new java.sql.Timestamp(millis);
ResultSet rs4 = null;
try
Class.forName("oracle.jdbc.driver.OracleDriver");
con = DriverManager.getConnection(
"jdbc:oracle:thin:@abc:1605:xyz",
"cdf", "cdf");
Statement stmt_exp = con.createStatement();
rs4 = stmt_exp.executeQuery("SELECT DATE FROM TABLE_NAME")
while (rs4.next()) {
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
con1.close();
catch (Exception e)
e.printStackTrace();
finally
//ResultSet rs4 = null;
//Timestamp timestamp2;
Timestamp timestamp2 = rs4.getTimestamp("expire_date");
if (timestamp2.compareTo(timestamp) < 0) //sysdate < exp date
return true;
} else {
return false;
}

Didn't you understand what BalusC said? You're closing the connection and then trying to use the ResultSet. The ResultSet will be closed when you close the connection so you can't use it anymore.
You should close the connection last thing in your code, probably in a finally. And after you close your ResultSet and Statement.

How to use Application Roles with Entity Framework

How does one call sp_setapprole before a connection used by an Entity Framework object context closes, since the context opens and closes its own connection automatically, as needed? The only relevant event available on a store connection
(DbConnection ) is StateChange , which does not include a
ConnectionState of Closing . Attempting to call
sp_setapprole when ConnectionState is Closed results in, "A severe error occurred on the current command. The results, if any, should be discarded."

Yes, I realize that I need to call sp_setapprole on an open connection and that I can use
ExecuteNonQuery or similar mechanisms. What I need to determine is how to do this
automatically while using the entity framework.
As I mentioned in my initial inquiry, the EF store connection, which is simply a DbConnection under the covers, does not expose an event (such as Closing) that would allow me to invoke
sp_setapprole before a connection is closed. The only close event we are given is
Closed , which is too late to do any good. I'm hoping to avoid burdening our systems with having to manually manage the connection.

Reference for writing COBOL prog with DB2 with ATMI calls for Oracle Tuxedo

Hi..
Am using IBM COBOL for AIX 2.0.0 on Oracle Tuxedo10g R3..
And for database IBM DB2 Version 8.2..
I have to write a program in Cobol with queries and with ATMI calls for Tuxedo..
I need some reference manuals for this or some sample program..
I also need the connectivity from cobol-DB2 to Tuxedo..
Can anyone send me link for the same?
The tutorial CSIMPAPP and STOCKAPP was really helpful..
Am searching for the similar kind..
Thanks in advance..
Edited by: user8103349 on Mar 19, 2009 8:43 PM

Hi,
Hopefully someone has some DB2 COBOL code to share. But in any case, using Tuxedo with COBOL and DB2 should be very similar to simply writing normal DB2 COBOL programs. The major difference is that Tuxedo will take care of making the connection to the database and should normally be allowed to perform all transaction management.
From a configuration standpoint you'll need to add the appropriate line in the Tuxedo RM file that lists how Tuxedo needs to link DB2 XA libraries into the application. The connection information is provided in the OPENINFO string passed along to the TMS that you need to build for DB2 with the buildtms command, and finally you'll need to build your servers with the -r switch to tell Tuxedo which XA libraries need to be linked into the application.
