QOCIDriver: unable to create environment

[ChrisW67]

ORACLE_HOME is an environment variable, or on Windows a registry entry, that almost all Oracle utilities use to find, among other things, the Oracle client and connection information files. ORACLE_HOME has nothing to do with Qt specifically and is set outside your program. ORACLE_HOME is generally set by the Oracle client installer. I suggest you need to consult your Oracle DBA or Oracle documentation.

Thank you.
I set varible environment :
Name: ORACLE_HOME
Value: C:\oraclexe\app\oracle\product\11.2.0\server

But it's error

[ChrisW67]

Take the "/server" off the end. The example in the FAQ I linked stops at the version numbered folder. You should be able to find a folder "bin" (usually contains sqlplus) in the folder pointed to by ORACLE_HOME.

Where is sqlplus.exe? Ignoring your program for the time being, can sqlplus connect to your database?

I do not propose to download and install an entire RDBMS just to answer your question.

I don't know @@
I have followed all instructions but when running any program error!!!!

[ChrisW67]

I know your program generates error messages, you do not need to keep saying that. The situation will not change until you start applying some effort to identifying the problem.

I connect MS SQL Server successfully but connect Oracle is very Complex @@

No, the Oracle client software needs to be installed correctly to be used. This is no different to the Microsoft SQL Server client, except that Microsoft install it with Windows.

How have you installed the Oracle client software? Do any of the Oracle utilities function for connecting to the database?

This is the last time I will ask:
Do any of the Oracle supplied utilities work to connect to your database?
