+ * returned on errors. If the result set contains fewer than two
+ * columns, a MDB2_ERROR_TRUNCATED error is returned.
+ *
+ * For example, if the table 'mytable' contains:
+ * <pre>
+ * ID TEXT DATE
+ * --------------------------------
+ * 1 'one' 944679408
+ * 2 'two' 944679408
+ * 3 'three' 944679408

+ *
+ * If the more than one row occurs with the same value in the
+ * first column, the last row overwrites all previous ones by
+ * default. Use the $group parameter if you don't want to
+ * overwrite like this. Example:
+ * <pre>
+ * getAssoc('SELECT category,id,name FROM mytable', null, null
+ * MDB2_FETCHMODE_ASSOC, false, true) returns:
+ * array(
+ * '1' => array(array('id' => '4', 'name' => 'number four'),
