 ====== A Basic Query ====== ====== A Basic Query ======
 The simplest way that ADOdb can retrieve data is through the [[v5:reference:connection:getall|getAll()]] method. This method reads the selected rows from the database into an array. Once retrieved, the data in the recordset is inserted into an array. The simplest way that ADOdb can retrieve data is through the [[v5:reference:connection:getall|getAll()]] method.

 +===== Changing How Data Is Returned =====
 The array can be returned in one of 3 ways: numeric, associative or mixed. The example above shows the returned data in associative format. In numeric format, the same array would look like this: The array can be returned in one of 3 ways: numeric, associative or mixed. The example above shows the returned data in associative format.
