示例1: dropTableEncryption

{
$tableName = $this->tableName;
if (!\OC_DB::tableExists($tableName)) {
return;
}
$sql = "select `uid`, max(`recovery_enabled`) as `recovery_enabled`, min(`migration_status`) as `migration_status` from `*PREFIX*{$tableName}` group by `uid`";
$query = \OCP\DB::prepare($sql);
$result = $query->execute(array())->fetchAll();
foreach ($result as $row) {
\OC_Preferences::setValue($row['uid'], 'files_encryption', 'recovery_enabled', $row['recovery_enabled']);
\OC_Preferences::setValue($row['uid'], 'files_encryption', 'migration_status', $row['migration_status']);
}
\OC_DB::dropTable($tableName);
}示例2: run
/**
* Fix duplicate entries in oc_lucene_status
*
* search_lucene prior to v0.5.0 did not have a primary key on the lucene_status table. Newer versions do, which
* causes the migration check to fail because it tries to insert duplicate rows into the new schema.
*
* FIXME Currently, apps don't have a way of repairing anything before the migration check:
* @link https://github.com/owncloud/core/issues/10980
*
* As a result this repair step needs to live in the core repo, although it belongs into search_lucene:
* @link https://github.com/owncloud/core/issues/10205#issuecomment-54957557
*
* It will completely remove any rows that make a file id have more than one status:
* fileid | status fileid | status
* --------+-------- will become --------+--------
* 2 | E 3 | E
* 2 | I
* 3 | E
*
* search_lucene will then reindex the fileids without a status when the next indexing job is executed
