The program supports a few ways to specify the number of rows to be generated.
Please note that all methods are applicable to "append" and "replace" row modes only.
For "Update" and "Scramble" modes the program operates with the whole source table. Please use "where" clause at the table tab to limit rows to be updated or scrambled.
By default, the user provides fixed values and the program generates the exact number* of data rows if it is possible.
* - the reference to the variable is acceptable as a constant number of rows as well as 'from' and 'to' borders of the range.
