Getting Data via ODBC from Oracle Server performance problem

41 Views

I wrote a C# assembly including a form with crystal reports viewer (Version: Crystal Reports Runtime 13.0.4). The data that should be displayed could be stored in various databases.

If I connect to e.g. MS SQL database the report is created and displayed very fast. Creating and displaying the report with getting the same data from an Oracle database takes much longer time.

I use the Oracle ODBC driver version 11g.

I’ve also tried the DataDirect ODBC Oracle driver but it takes even more time than the Oracle driver.

Does anyone know this issue? Could this be a general problem in Crystal Reports Viewer or is it depending to the driver.

Many thanks in advance!
