The program supports a few ways to
specify number of rows to be generated.
By default the user enters fixed values and the program generates
required number of data rows. Also available:
Random method. In this case the program will generate random
number of rows in the range specified by user.
By another method. The generator will create same number of
rows as contained in another table of the same database.
By SQL statement. This way allows the user o define SQL
statement that will be executed before generation. The first result
will be user as number of rows.
By data from another table. In this case the program will
generate defined number of rows for each unique value from
specified 'table.column'.
