- * 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'),
