		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.

getQueryInfo()

Wikibase\Lib\Store\Sql\PageTableEntityQueryBase::getQueryInfo ( array  $entityIds, bool  $usesRevisionTable, IDatabase  $db  )

private

Parameters

EntityId[]	$entityIds
bool	$usesRevisionTable
IDatabase	$db

Returns

array [ string $whereCondition, array $extraTables ]

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.

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	$joins,
		array	$entityIds,
		IDatabase	$db
	)

Parameters

array	$fields	Fields to select
array	$joins	Joins to use, Keys must be table names.
EntityId[]	$entityIds	EntityIds to select
IDatabase	$db	DB to query on

Returns

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

Implements Wikibase\Lib\Store\Sql\PageTableEntityQuery.
