main

public static void main(String[] args)
                 throws Exception

Usage: java org.apache.openjpa.jdbc.kernel.ValueTableJDBCSeq [option]* -action/-a <add | drop | get | set> [primary key value] [value] Where the following options are recognized.

• -properties/-p <properties file or resource>: The path or resource name of a OpenJPA properties file containing information such as the license key and connection data as outlined in JDBCConfiguration. Optional.
• -<property name> <property value>: All bean properties of the OpenJPA JDBCConfiguration can be set by using their names and supplying a value. For example: -licenseKey adslfja83r3lkadf

The various actions are as follows.

• add: Create the sequence table.
• drop: Drop the sequence table.
• get: Print the current sequence value for the given primary key value.
• set: Set the sequence value for the given primary key value.

Throws:

Exception
