]示例6: query
def query(self, *query, **kwargs):
"""
query(*query[, sortby])
Send the given query to the database and return a list of
database entries that satisfy all of the given attributes.
Apart from the attributes supported by the VSO interface, the following
attributes are supported:
- :class:`sunpy.database.attrs.Starred`
- :class:`sunpy.database.attrs.Tag`
- :class:`sunpy.database.attrs.Path`
- :class:`sunpy.database.attrs.DownloadTime`
- :class:`sunpy.database.attrs.FitsHeaderEntry`
An important difference to the VSO attributes is that these attributes
may also be used in negated form using the tilde ~ operator.
Parameters
----------
query : list
A variable number of attributes that are chained together via the
boolean AND operator. The | operator may be used between attributes
to express the boolean OR operator.
sortby : str, optional
The column by which to sort the returned entries. The default is to
sort by the start of the observation. See the attributes of
:class:`sunpy.database.tables.DatabaseEntry` for a list of all
possible values.
Raises
------
TypeError
if no attribute is given or if some keyword argument other than
'sortby' is given.
Examples
--------
The query in the following example searches for all non-starred entries
with the tag 'foo' or 'bar' (or both).
>>> database.query(~attrs.Starred(), attrs.Tag('foo') | attrs.Tag('bar'))
