public class longvarchar

extends java.lang.Object

This example is a standalone application demonstrating a method for inserting and retrieving data from Oracle long raw columns.

To use this example, pass four command line parameters to the main() method. The first three parameters are for database access, and the fourth is the name of a file to be inserted, and then retrieved from the database.

Please note that this example uses a simple method for obtaining result sets, update counts, and/or the output parameter values it may generate. This is always possible with simple, known queries. When executing complex or unknown possibly multi-statement SQL or stored procedures, you should use the example in storedprocs.java to ensure that all results become available.

Build the Example

1. In the %SAMPLES_HOME%\examples.properties file, specify a value for the following properties:
   • DBSERVER - The name of your Oracle server.
   • USER - The user name to use to connect to the database and create tables.
   • PASSWORD - The password to use when connecting to the database.

   The ant scripts for building and running the example use properties set in this file.

2. Open a new command shell.

3. Set up this development shell as described in Setting up Your Environment for Building and Running the Examples.
   • Update your PATH to include the path to the directory for the WebLogic shared library (native interface) for oci817_8 and to the directory for libraries for the Oracle client. For example:

     %WL_HOME%\server\bin\oci817_8;%ORACLE_HOME%\bin;%PATH%

     where %WL_HOME% is where you installed the WebLogic software.

   For complete information, see Setting Up the Environment for Using WebLogic jDriver for Oracle in Installing and Using WebLogic jDriver for Oracle. The following sections contain instructions for specific platforms:

   • Windows NT
   • Solaris
   • HP

4. Compile the example by executing the following command:

     prompt> ant

   Note: This script builds all of the examples in the oracle directory.

Run the Example

• Execute the following command in your development shell:

    prompt> ant longvarchar

  Parameters contained within the run script are:

  • USERNAME: Username for the database connection.

  • PASSWORD: Password for the user.

  • DBMS: TNS alias for the DBMS server.

  • FILENAME: Name of the file to be inserted into the DBMS.

    The file returned by a query is the same, with ".out" appended.
