PHP DatabaseConnection::stripOrderBy方法代码示例

 /**
  * Executes a standard SELECT query for listing of records based on standard input vars from the 'browser' ($this->internal['results_at_a_time'] and $this->piVars['pointer']) and 'searchbox' ($this->piVars['sword'] and $this->internal['searchFieldList'])
  * Set $count to 1 if you wish to get a count(*) query for selecting the number of results.
  * Notice that the query will use $this->conf['pidList'] and $this->conf['recursive'] to generate a PID list within which to search for records.
  *
  * @param string $table The table name to make the query for.
  * @param bool $count If set, you will get a "count(*)" query back instead of field selecting
  * @param string $addWhere Additional WHERE clauses (should be starting with " AND ....")
  * @param mixed $mm_cat If an array, then it must contain the keys "table", "mmtable" and (optionally) "catUidList" defining a table to make a MM-relation to in the query (based on fields uid_local and uid_foreign). If not array, the query will be a plain query looking up data in only one table.
  * @param string $groupBy If set, this is added as a " GROUP BY ...." part of the query.
  * @param string $orderBy If set, this is added as a " ORDER BY ...." part of the query. The default is that an ORDER BY clause is made based on $this->internal['orderBy'] and $this->internal['descFlag'] where the orderBy field must be found in $this->internal['orderByList']
  * @param string $query If set, this is taken as the first part of the query instead of what is created internally. Basically this should be a query starting with "FROM [table] WHERE ... AND ...". The $addWhere clauses and all the other stuff is still added. Only the tables and PID selecting clauses are bypassed. May be deprecated in the future!
  * @return bool|\mysqli_result|object SQL result pointer
