◆ addWhere()

ApiQueryBase::addWhere ( $value )

protected

Add a set of WHERE clauses to the internal array.

The array should be appropriate for passing as $conds to IDatabase::select(). Arrays from multiple calls are merged with array_merge(). A string is treated as a single-element array.

When passing ‘'field’ => $arrayOfIDs` where the IDs are taken from user input, consider using addWhereIDsFld() instead.

See also: IDatabase::select()

Parameters

string | array $value

References getQueryBuilder().

◆ addWhereFld()

ApiQueryBase::addWhereFld	(		$field,
			$value )

protected

Equivalent to addWhere( [ $field => $value ] )

When $value is an array of integer IDs taken from user input, consider using addWhereIDsFld() instead.

Parameters

string	$field	Field name
int \| string \| string[] \| int[]	$value	Value; ignored if null or empty array

◆ addWhereIDsFld()

ApiQueryBase::addWhereIDsFld	(	$table,
		$field,
		$ids )

protected

Like addWhereFld for an integer list of IDs.

When passed wildly out-of-range values for integer comparison, the database may choose a poor query plan. This method validates the passed IDs against the range of values in the database to omit out-of-range values.

This should be used when the IDs are derived from arbitrary user input; it is not necessary if the IDs are already known to be within a sensible range.

This should not be used when there is not a suitable index on $field to quickly retrieve the minimum and maximum values.

Since: 1.33

Parameters

string	$table	Table name
string	$field	Field name
int[]	$ids

Returns: int Count of IDs actually included

bool	$condition	If false, do nothing

protected

Add a WHERE clause corresponding to a range, and an ORDER BY clause to sort in the right direction.

Parameters

string	$field	Field name
string	$dir	If 'newer', sort in ascending order, otherwise sort in descending order
string \| int \| null	$start	Value to start the list at. If $dir == 'newer' this is the lower boundary, otherwise it's the upper boundary
string \| int \| null	$end	Value to end the list at. If $dir == 'newer' this is the upper boundary, otherwise it's the lower boundary
bool	$sort	If false, don't add an ORDER BY clause

◆ getQueryBuilder()

ApiQueryBase::getQueryBuilder ( )

protected

Get the SelectQueryBuilder.

This is lazy initialised since getDB() fails in ApiQueryAllImages if it is called before the constructor completes.

Returns: SelectQueryBuilder

◆ parsePrefixedTitlePart()

ApiQueryBase::parsePrefixedTitlePart	(		$titlePart,
			$defaultNamespace = NS_MAIN )

protected

Convert an input title or title prefix into a TitleValue.

Since: 1.35

Parameters

string	$titlePart
int	$defaultNamespace	Default namespace if none is given

Returns: TitleValue

Definition at line 556 of file ApiQueryBase.php.

References $t, ApiBase\dieWithError(), and wfEscapeWikiText().

◆ processRow()

ApiQueryBase::processRow	(		$row,
		array &	$data,
		array &	$hookData )

protected

Call the ApiQueryBaseProcessRow hook.

Generally, a module that passed $hookData to self::select() will call this just before calling ApiResult::addValue(), and treat a false return here in the same way it treats a false return from addValue().

Since: 1.28

Parameters

stdClass	$row	Database row
array	&$data	Data to be added to the result
array	&$hookData	Hook data from ApiQueryBase::select()

Returns: bool Return false if row processing should end with continuation

◆ requestExtraData()

ApiQueryBase::requestExtraData ( $pageSet )

Override this method to request extra fields from the pageSet using $pageSet->requestField('fieldName')

Note this only makes sense for 'prop' modules, as 'list' and 'meta' modules should not be using the pageset.

Stability: stable: to override

Parameters

ApiPageSet $pageSet

Reimplemented in ApiQueryInfo.

◆ resetQueryParams()

ApiQueryBase::resetQueryParams ( )

protected

Blank the internal arrays with query parameters.

◆ select()

ApiQueryBase::select	(		$method,
			$extraQuery = [],
		array &	$hookData = null )

protected

Execute a SELECT query based on the values in the internal arrays.

Parameters

string	$method	Function the query should be attributed to. You should usually use METHOD here
array	$extraQuery	Query data to add but not store in the object Format is [ 'tables' => ..., 'fields' => ..., 'where' => ..., 'options' => ..., 'join_conds' => ... ]
array \| null	&$hookData	If set, the ApiQueryBaseBeforeQuery and ApiQueryBaseAfterQuery hooks will be called, and the ApiQueryBaseProcessRow hook will be expected.

Returns: IResultWrapper

Definition at line 401 of file ApiQueryBase.php.

◆ selectNamedDB()

ApiQueryBase::selectNamedDB	(	$name,
		$db,
		$groups )

Change the database connection for subsequent calls to getDB().

See ApiQuery::getNamedDB() for more information.

Deprecated: since 1.39 Use or override ApiBase::getDB() and optionally pass a query group to wfGetDB() or ILoadBalancer::getConnectionRef().

Parameters

string	$name	Name to assign to the database connection
int	$db	One of the DB_* constants
string \| string[]	$groups	Query groups

Returns: IDatabase

◆ setContinueEnumParameter()

ApiQueryBase::setContinueEnumParameter	(		$paramName,
			$paramValue )

protected

Set a query-continue value.

Parameters

string	$paramName	Parameter name
int \| string \| array	$paramValue	Parameter value

◆ titlePartToKey()

ApiQueryBase::titlePartToKey	(		$titlePart,
			$namespace = NS_MAIN )

Convert an input title or title prefix into a dbkey.

$namespace should always be specified in order to handle per-namespace capitalization settings.

Parameters

string	$titlePart
int	$namespace	Namespace of the title

Returns: string DBkey (no namespace prefix)
