Step 3 - Specifying generation parameters


At this step you can select fields for generating data and set various data generation parameters.

 

Selected tables are displayed in the Generate data for tree at the top-left side of the window. Table fields and their types are listed in the grid of the Field list area below.

 

Records count

Set the number of data records to be generated for each table.

 

CheckBox Clear

Set this flag for a table to empty the table before data generation.

 

Disable triggers

This column is visible if there are active triggers on one or more tables selected for data generation. Set a flag for a table to disable triggers associated with the table during data generation.

 

Insert type

Use the drop-down list to select the data insertion type:

  • insert: common data insertion type
  • merge: data are read from the source and INSERT or UPDATE operation is performed in the target table depending on a condition (note that for this generation type you will need to select a key field; if the table has a key field, this field will be automatically selected as the key field for the merge operation)

 

Preview

Click the Preview button to browse the selected table data in the preview mode.

 

Step 3 - Specifying generation parameters

 

 

When you select a table in the Generate data for tree, you can set data generation parameters for each of its fields within the Generation properties area at the right side of the window. Use the btnSelectAll btnUnselectAll and the btnInvertSelection buttons to manage fields within the Field list area. For each field you can set the following:

 

CheckBox Set NULL value in ... % of cases

Check this option and specify the percentage of NULL values for the field, if necessary.

 

Other generation parameters vary according to the data type of the selected field:

 

If a field is part of a foreign key, you can select one of the following options for this field:

 

RadioButton Generate data from the dependent field

Values for the field will be taken from the corresponding field(s) of the foreign table(s).

 

RadioButton Generate data from list / SQL-query

 RadioButton Ratio 1:N

If this option is selected you should specify the N value using the spin-edit box below. Data will be generated into the field related as 1:N, i.e. n records will be generated into the foreign table for each record of the primary table.

 

Step 3 - Generation properties - Ratio

 

 

When you are done, press the Next button to proceed to the next step of the Wizard.
