NUMBER column parameters

Number data are used in Oracle databases for exact numeric data storage. Values for this column can be generated randomly, incrementally, or they can be taken from a fixed list of values or SQL query, or from an existing table column of the same data type.

The Generation properties panel allows you to define preferences for generating values for numeric data types.

Select Data generation mode as follows:

Generate random data

Here you can define the number of precision and the scale for the result values.

Generate incremental data

Specify the Initial value and the Increment properties to generate an ordered incremented sequence of values.

Get Data from List / SQL query

This panel allows you to define the list of values to generate numeric 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 Add Value button.

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

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

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

To remove all items from the list, use the 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.

Get data from column

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