|3. What is difference between the Paradox2DB2
Package, Embedded(WithDrv) Package, Embedded(WithoutDrv) Package?
The Paradox2DB2 Package is a GUI application , and the Embedded package is a package which can load into DB2 database(DB2 8 or upper). If you're exporting data by GUI application or a configuration file, you should use the Paradox2DB2 Package . If you want to export data more quickly and more flexibly, you can use the Paradox2DB2 Embedded Package.
As the tips by the name, Embedded(WithDrv) Package contains the HXTT Paradox JDBC package, and Embedded(WithoutDrv) Package doesn't.
|4. What's the difference between the
professional Paradox2DB2 Package and the enterprise Paradox2DB2 Package?
The standard Paradox2DB2 Package can export table data to DB2 from Corel Paradox.
The enterprise Paradox2DB2 Package contains the function of standard Paradox2DB2 Package, besides, it can export data accord view or a dynamic query, and execute export operation from a configuration file saved by prior export operation, and loaded into DB2 database(DB2 8 or upper) for build a procedure to export data.
|5. What causes the 'No suitable driver' SQLException?
This error usually occurs during a call to DriverManager.getConnection(). The cause can be failing to load the appropriate JDBC driver before calling getConnection(), or specifying an invalid JDBC URL that isn't recognized by your JDBC driver. If you are exporting data by GUI application or a configuration file, you should check the DB2 JDBC package exists in the directory in your driver config, and check your JDBC url. If you are using Embedded(WithoutDrv) Package to export data in DB2 database, this error happens is because you haven't load the HXTT Paradox JDBC package in DB2 database.
|6. What's the diffirence between the HXTT Paradox
JDBC package contained in DataExp 2007 program and the standard HXTT Paradox
The HXTT Paradox JDBC package contained in DataExp 2007 program can only used in DataExp 2007 program and have some functional limit, so you cann't use it for other usage.
There are no other difference between the two package. They can accept the same jdbc url, and connect properties, and operate data, etc.
|7. Can export a table data to a non-exists table?
Yes. This package will auto create the destination table. In the GUI application, you can change the table structure when need creating the table.
|8. I would like to export data from our application, instead of load it in DB2 database or GUI application. can do so?|
|Yeah. You can do so if you buy the Enterprise Paradox2DB2 product . Maybe you should pay the attention to the licence.|
There is a class named com.hxtt.data.export.advance.Paradox2DB2 in the Embedded(WithDrv) Package and Embedded(WithoutDrv) Package contains a series method to export data.
All public method please see here.
|9. May I execute export operation at a assign time?|
|Yeah. You can execute export operation from a configuration file saved by prior export operation. So, you can use the Task Scheduler(in Windows) or Crontab(in Unix/Linux) to execute export operation.|
