## Required query parameters

When you declare a default value for non-path parameters (for now, we have only seen query parameters), then it is not required.

If you don't want to add a specific value but just make it optional, set the default as `None`.

But when you want to make a query parameter required, you can just not declare any default value:

```Python hl_lines="6-7"

# /---------------------------------------------------------------------------

#
# The basic information for the tasks of DBFlute.
# You should specify before your first generating.

# o targetLanguage: (Required)
# o targetContainer: (Required)
# o packageBase: (Required)
