Constructor & Destructor Documentation

__construct()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::__construct	(	EntityNamespaceLookup	$entityNamespaceLookup,
		NameTableStore	$slotRoleStore )

Member Function Documentation

getConditionForEntityId()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::getConditionForEntityId ( EntityId $entityId )

abstractprotected

Parameters

EntityId

$entityId

Returns

array SQL condition

Reimplemented in Wikibase\Lib\Store\Sql\EntityIdLocalPartPageTableEntityQuery.

getEntityIdStringFromRow()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::getEntityIdStringFromRow ( stdClass $row )

abstractprotected

Parameters

stdClass

$row

Returns

string serialization of an entity ID for example Q123

Reimplemented in Wikibase\Lib\Store\Sql\EntityIdLocalPartPageTableEntityQuery.

getFieldsNeededForMapping()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::getFieldsNeededForMapping ( )

abstractprotected

Returns

string[] Extra fields needed for the mapping done in mapRowsToEntityIds

Reimplemented in Wikibase\Lib\Store\Sql\EntityIdLocalPartPageTableEntityQuery.

indexRowsByEntityId()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::indexRowsByEntityId ( Traversable $rows )

private

Parameters

Traversable

$rows

Returns

stdClass[] Array of rows with keys of their entity ID serializations

selectRows()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::selectRows	(	array	$fields,
		?array	$revisionJoinConds,
		array	$entityIds,
		IReadableDatabase	$db )

Parameters

array	$fields	Fields to select
array | null	$revisionJoinConds	If non-null, perform an INNER JOIN against the revision table on these join conditions.
EntityId[]	$entityIds	EntityIds to select
IReadableDatabase	$db	DB to query on

Returns

stdClass[] Array of rows with keys of their entity ID serializations

Implements Wikibase\Lib\Store\Sql\PageTableEntityQuery.

updateQueryBuilder()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::updateQueryBuilder ( SelectQueryBuilder $queryBuilder, array $entityIds, IReadableDatabase $db )

private

Parameters

SelectQueryBuilder	$queryBuilder
EntityId[]	$entityIds
IReadableDatabase	$db

Only check against the slot role when we are not using the main slot. If we are using the main slot, then we only need to check that the page exists rather than a specific slot within the page. This ensures comparability with the pre MCR schema as long as only the main slot is used.
