fit_database
============
This ``str`` is the name of a :ref:`glossary@fit_database` .

root_database
=============
This ``str`` is the name of a :ref:`glossary@root_database` .

table = fit_or_root.get_table(table_name)
{xrst_code}

table_name
==========
This ``str`` the name of the table that we are getting.

table
=====
This is a ``list`` of ``dict`` representation of the table.
If *table_name* is a
:ref:`constant table <module@at_cascade.constant_table_list>` ,
*table* is retrieved from the root node database.
Otherwise it is retrieved from the fit node database.

null_row
********
{xrst_code py}
row = fit_or_root.null_row(table_name)
{xrst_code}

table_name
==========
This ``str`` the name of the table that we getting a null row for.

row
===
is a ``dict`` with one key for every column in the table specified
by *table_name* and all the values equal to ``None`` .

This closes the database connection held by a fit_or_root.
The ``get_table`` function will no longer be available.
