Online Documentation for Data Generator for PostgreSQL

GEOMETRIC field parameters

Geometric data types represent two-dimensional spatial objects. You can generate values for this field randomly or choose to take them from a specified list of values or SQL query, or from an existing table field of the same data type.


The Generation properties panel allows you to define preferences for generating values for geometric field types.


Geometric field parameters



Select Data generation mode as follows:


RadioButton Generate random data

The coordinates are generated randomly within the defined intervals (the minimum and the maximum values).


Geometric field parameters - Mode - Random data



RadioButton Get data from list / SQL query

This panel allows you to define the list of values to generate geometric data from. You can enter these values directly into the editor by selecting the List of Values option.

To add a single value, use the btnListAddValue Add Value button.

To load a list of values from an existing external file, use the btnListLoadFromFile Load from file button.

To save the list to an external file, use the btnListSaveToFile Save to file button.

To remove a single value, use the btnListDeleteValue Delete Value button.

To remove all items from the list, use the btnListClear Clear button.


You can also specify whether the values are to be taken in random order or in the order they have been inputted.


Alternatively, you can set the SQL Query option and input an SQL query into the editor, and the resulting dataset will be used as the list for data generation.


Geometric field parameters - Mode - List or query



RadioButton Get data from Field

This option allows you to specify a field to generate data from: use the Table and Field drop-down lists to select the source table and field that will be used to take data for generation.
