_get_query(self,
select_clause,
index,
new_index,

get_query(self,
index,
constraints)
Return a query clause, associated values, and an updated table index (as
a 3-tuple) for this object's query defined using the given table 'index'
and the supplied, optional 'constraints' text. |

get_subquery(self,
parent_columns,
parent_index,
index,
match_first,
match_parent,

Make a subquery for this object using the given 'parent_columns'
(indicating the columns which connect with this object's exposed
columns), a 'parent_index' (indicating the table index used in the

fn,
column) |
| |
_ensure(self)
Ensure the the query has been executed. |

method. |
| |
_get_columns(self,
exposed_columns,
index,
limited_to)
