AndQuery

class beets.dbcore.query.AndQuery(subqueries: Sequence[Query] = ())

Bases: MutableCollectionQuery

A conjunction of a list of other queries.

__init__(subqueries: Sequence[Query] = ())

Public methods summary

clause()	Generate an SQLite expression implementing the query.
clause_with_joiner(joiner)	Return a clause created by joining together the clauses of all subqueries with the string joiner (padded by spaces).
match(obj)	Check whether this query matches a given Model.

Methods definition

clause() → tuple[str | None, Sequence[str | bytes | float | int | memoryview | None]]

Generate an SQLite expression implementing the query.

Return (clause, subvals) where clause is a valid sqlite WHERE clause implementing the query and subvals is a list of items to be substituted for ?s in the clause.

The default implementation returns None, falling back to a slow query using match().

clause_with_joiner(joiner: str) → tuple[str | None, Sequence[str | bytes | float | int | memoryview | None]]

Return a clause created by joining together the clauses of all subqueries with the string joiner (padded by spaces).

property field_names: set[str]

Return a set with field names that this query operates on.

match(obj: Model) → bool

Check whether this query matches a given Model. Can be used to perform queries on arbitrary sets of Model.
