◆ addWhereFld()

◆ addWhereIDsFld()

MediaWiki\Api\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$tableTable name
string$fieldField name
int[]$ids
Returns
int Count of IDs actually included

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$rowDatabase row
array&$dataData to be added to the result
array&$hookDataHook data from ApiQueryBase::select()
Returns
bool Return false if row processing should end with continuation
