#include <Core/Core.h>
#include <Oracle/Oracle8.h>
#include <iostream>

CONSOLE_APP_MAIN
{
	Oracle8 oracle;
	Cout() << "Connecting...\n" ;
	Cout() << "Connect state: " << oracle.Open("xxx/yyy@zzz") << "\n" ;
	
	Sql sql(oracle);
	
	String cmd = "select * from tab;" ;

	sql.Execute ( cmd ) ;
	Cout() << "Excute done...\n" ;
        // Everything right here.. 
	while( sql.Fetch() )  // this line wrong.. in the function Fetch(), a ASSERTION error...
	    Cout() << String(sql[0]) << ": " << String(sql[1]);
	
}


So.. What can I do know ^^?
Thx a lot.

Well, all of my money are from connecting Oracle8 to Oracle 10 Smile

ASSERT in Fetch usually indicates SQL error. Not 100% sure now, but I think that semicolon can produce it.

In any case, use sql.SetTrace() in debug mode to find out what is wrong with your SQL.

Thank you very much.

Hi,

I tried to see this code running to learn more about U++ and the connection to Oracle databases, but the only result I obtained were errors (a lot of them, unfortunately...). I tried to compile with MingW (and MSC) the code below:

#include <Core/Core.h>
#include <Oracle/Oracle8.h>
#include <iostream>


CONSOLE_APP_MAIN
{
Oracle8 oracle;
Cout() << "Connecting...\n";
Cout() << "Connect state: " << oracle.Open("scott/tiger@prev") << "\n";

Sql sql(oracle);

String cmd = "select * from emp" ;
Cout() << "Executing " << cmd << "...\n";
sql.Execute ( cmd ) ;
Cout() << "Execute done...\n";
// Everything right here..
while( sql.Fetch() ) // this line wrong.. in the function Fetch(), a ASSERTION error...
Cout() << String(sql[0]) << ": " << String(sql[1]) << "\n ";

}

The code above I named it "SQL_Oracle2", because I checked the sintax and compared the code with another example, named "SQL_Oracle". Probably I'm doing something wrong, but I could't find why I had problems with a little piece of code. Please take a look in the attached file, also. If anybody could help, any advice should VERY appreciated...

Tks in adv,
Sven

There is missing

using namespace Upp;

Acutally, this code does not connect to the database:

oracle.Open("scott/tiger@cxl");

Please do not post those zips, if you are getting a lot of problem, just list them in the message. Did not had to send .pngs. Errors listing would have been enough.

Hi Mirek,

Tks for your comments, because only after them was possible to see this sample code running. Sorry for my lack of enough knowledge about U++/C++, but I'm waiting for the U++ Users Manual (or other type of How-Tos), too Very Happy . But an error appeared, like "Assertion failed in C:\upp\Core/Value.h, line 431, dynamic_cast<const RichValueRep *(p)". What this problem could mean ? Confused

I couldn't understant what you said about not connecting to the database, also. Because was possible to connect... Very Happy

And regarding to the jpg images, please don't be bored about this. I sent (in compressed form, of course) it only to be possible to see what is really happening, in the screen. These files are for problem explanation purposes, only... Very Happy

Regards,
Sven

This means you are retrieving incompatible type. Like Value has String inside and you are trying to convert it to int.

Please do not do that! Quote error messages, code, or zip your main package and post.

Fortunately, I choosed a good environment. Having Oracle access through U++ was a very good thing, when looking for performance...

And, if you could add more details about using sql.SetTrace, should be very appreciated, also...

Just use SetTrace and you will have all SQL statements issued logged (in .log file).

Hello All!

Can I connect Upp::Oracle8 through Oracle10 OCI on ubuntu? I have installed Oracle client 10g2. From sqlplus connection through tnsname works fine.

I compiled the application but when I run I get the error message:
Error loading OCI8 Oracle connection dynamic library.

What I did wrong?

I see that I need to copy oci.dll in the same directory? what file from #ORACLE_HOME?

Help please!

Thanks in advance!
