|3. What is difference between the Oracle2Text
Package, Embedded(WithDrv) Package, Embedded(WithoutDrv) Package?
The Oracle2Text Package is a GUI application , and the Embedded package is a package which can load into Oracle database(Oracle8i or upper). If you're exporting data by GUI application or a configuration file, you should use the Oracle2Text Package . If you want to export data more quickly and more flexibly, you can use the Oracle2Text Embedded Package.
As the tips by the name, Embedded(WithDrv) Package contains the HXTT Text JDBC package, and Embedded(WithoutDrv) Package doesn't.
|4. What's the difference between the
professional Oracle2Text Package and the enterprise Oracle2Text Package?
The standard Oracle2Text Package can export table data to CSV(TSV, PSV) from Oracle.
The enterprise Oracle2Text Package contains the function of standard Oracle2Text 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 Oracle(8i 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 Oracle 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 Oracle database, this error happens is because you haven't load the HXTT Text JDBC package in Oracle database.
|6. What's the diffirence between the HXTT Text
JDBC package contained in DataExp 2007 program and the standard HXTT Text
The HXTT Text 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 Oracle database or GUI application. can can do so?|
|Yeah. You can do so if you buy the Enterprise Oracle2Text product . Maybe you should pay the attention to the licence.|

|You can do as follows.|
|In windows Command or Shell(Linux/Unix), run the follows command to load
the embed package into Oracle database.
loadjava -resolve -synonym -verbose -user username/password@OracleSid EMBOracle2Text_WithDRV.jar
Then, you should create the follows procedure,
sourceschemaname in varchar2,
targetdirectory in varchar2,
targettablename in varchar2,
