Java SE example: Displaying database schema information

Run the Java SE sample to gain an understanding of how UltraLite Java edition database system tables are traversed to examine the schema information.
Prerequisites
There are no prerequisites for this task.
Task

Change to the following directory: %SQLANYSAMP16%\UltraLiteJ\J2SE.
Run the CreateSales example:
rundemo CreateSales
Run the following command (the command is case sensitive):
rundemo DumpSchema
Results
The data for each row of the tables also appears. The following output is displayed:
Metadata options:

Option[ date_format ] = 'YYYY-MM-DD'
Option[ date_order ] = 'YMD'
Option[ global_database_id ] = '0'
Option[ nearest_century ] = '50'
Option[ precision ] = '30'
Option[ scale ] = '6'
Option[ time_format ] = 'HH:NN:SS.SSS'
Option[ timestamp_format ] = 'YYYY-MM-DD HH:NN:SS.SSS'
Option[ timestamp_increment ] = '1'
