<p>This function can be called by any code which wishes to change a
song property and send a notification. It may be called when the
database is read-only; in this case the change will be queued for
an unspecified time in the future. The implication of this is that
<a class="link" href="RhythmDB.html#rhythmdb-entry-get" title="rhythmdb_entry_get ()"><code class="function">rhythmdb_entry_get()</code></a> may not reflect the changes immediately. However,
if this property is exposed in the user interface, you should still
make the change in the widget. Then when the database returns to a
writable state, your change will take effect in the database too,
and a notification will be sent at that point.</p>
<p>Note that you must call <a class="link" href="RhythmDB.html#rhythmdb-commit" title="rhythmdb_commit ()"><code class="function">rhythmdb_commit()</code></a> at some point after invoking
this function, and that even after the commit, your change may not

<em class="parameter"><code>...</code></em>);</pre>
<p>Creates a query from a list of criteria.</p>
<p>Most criteria consists of an operator (<a class="link" href="RhythmDB.html#RhythmDBQueryType" title="enum RhythmDBQueryType"><span class="type">RhythmDBQueryType</span></a>),
a property (<a class="link" href="RhythmDB.html#RhythmDBPropType" title="enum RhythmDBPropType"><span class="type">RhythmDBPropType</span></a>) and the data to compare with. An entry
matches a criteria if the operator returns true with the value of the
entries property as the first argument, and the given data as the second
argument.</p>
<p>Three types criteria are special. Passing RHYTHMDB_QUERY_END indicates the
end of the list of criteria, and must be the last passes parameter.</p>
<p>The second special criteria is a subquery which is defined by passing
RHYTHMDB_QUERY_SUBQUERY, followed by a query (<a href="../glib/glib-Pointer-Arrays.html#GPtrArray"><span class="type">GPtrArray</span></a>). An entry will
match a subquery criteria if it matches all criteria in the subquery.</p>
<p>The third special criteria is a disjunction which is defined by passing
RHYTHMDB_QUERY_DISJUNCTION, which will make an entry match the query if
it matches the criteria before the disjunction, the criteria after the
disjunction, or both.</p>
<p>Example:
rhythmdb_query_parse (db,
RHYTHMDB_QUERY_SUBQUERY, subquery,
RHYTHMDB_QUERY_DISJUNCTION
RHYTHMDB_QUERY_PROP_LIKE, RHYTHMDB_PROP_TITLE, "cat",
RHYTHMDB_QUERY_DISJUNCTION
RHYTHMDB_QUERY_PROP_GREATER, RHYTHMDB_PROP_RATING, 2.5,
RHYTHMDB_QUERY_PROP_LESS, RHYTHMDB_PROP_PLAY_COUNT, 10,
RHYTHMDB_QUERY_END);</p>
<p> will create a query that matches entries:
a) that match the query "subquery", or
b) that have "cat" in their title, or
c) have a rating of at least 2.5, and a play count of at most 10</p>

<p>Preprocesses a query to prepare it for execution. This has two main
roles: to perform expensive data transformations once per query, rather
than once per entry, and converting criteria to lower-level forms that
are implemented by the database backend.</p>
<p>For RHYTHMDB_PROP_SEARCH_MATCH, this converts the search terms into
an array of case-folded words.</p>
<p>When matching against case-folded properties such as
<a class="link" href="RhythmDB.html#RHYTHMDB-PROP-TITLE-FOLDED:CAPS"><span class="type">RHYTHMDB_PROP_TITLE_FOLDED</span></a>, this case-folds the query value.</p>
<p>When performing year-based criteria such as <a class="link" href="RhythmDB.html#RHYTHMDB-QUERY-PROP-YEAR-LESS:CAPS"><span class="type">RHYTHMDB_QUERY_PROP_YEAR_LESS</span></a>,
it converts the year into the Julian date such that a simple numeric

<p>Emits a request for extra metadata for the <em class="parameter"><code>entry</code></em>
.
The <em class="parameter"><code>property_name</code></em>
argument is emitted as the ::detail part of the
"entry_extra_metadata_request" signal. It should be a namespaced RDF
predicate e.g. from Dublin Core, MusicBrainz, or internal to Rhythmbox
(namespace "rb:"). Suitable predicates would be those that are expensive to
acquire or only apply to a limited range of entries.
Handlers capable of providing a particular predicate may ensure they only
see appropriate requests by supplying an appropriate ::detail part when
connecting to the signal. Upon a handler returning a non-<a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> value,
emission will be stopped and the value returned to the caller; if no
handlers return a non-<a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> value, the caller will receive <a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a>. Priority
is determined by signal connection order, with <a href="../gobject/gobject-Signals.html#G-CONNECT-AFTER:CAPS"><code class="literal">G_CONNECT_AFTER</code></a> providing a
second, lower rank of priority.
A handler returning a value should do so in a <a href="../gobject/gobject-Generic-values.html#GValue"><span class="type">GValue</span></a> allocated on the heap;
the accumulator will take ownership. The caller should unset and free the
<a href="../gobject/gobject-Generic-values.html#GValue"><span class="type">GValue</span></a> if non-<a href="../glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> when finished with it.</p>
