- * remove
- *
- * Associative array with the names of fields to be removed as indexes
- * of the array. Currently the values assigned to each entry are ignored.
- * An empty array should be used for future compatibility.
- *
- * rename
- *
- * Associative array with the names of fields to be renamed as indexes
- * of the array. The value of each entry of the array should be set to
- * another associative array with the entry named name with the new
- * field name and the entry named Declaration that is expected to contain
- * the portion of the field declaration already in DBMS specific SQL code
- * as it is used in the CREATE TABLE statement.
- *
- * change
- *
- * Associative array with the names of the fields to be changed as indexes
- * of the array. Keep in mind that if it is intended to change either the
- * name of a field and any other properties, the change array entries
- * should have the new names of the fields as array indexes.
- *
- * The value of each entry of the array should be set to another associative
- * array with the properties of the fields to that are meant to be changed as
- * array entries. These entries should be assigned to the new values of the
- * respective properties. The properties of the fields should be the same
- * as defined by the MDB2 parser.
- *
- * Example
- * array(
- * 'name' => 'userlist',
- * 'add' => array(
- * 'quota' => array(
- * 'type' => 'integer',
- * 'unsigned' => 1
- * )
- * ),
- * 'remove' => array(
- * 'file_limit' => array(),
- * 'time_limit' => array()
- * ),
- * 'change' => array(
- * 'name' => array(
- * 'length' => '20',
- * 'definition' => array(
- * 'type' => 'text',
- * 'length' => 20,
- * ),
- * )
- * ),
- * 'rename' => array(
- * 'sex' => array(
- * 'name' => 'gender',

- * 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

- *
- * If the more than one row occurs with the same value in the

- * 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:

- * '1' => array(array('id' => '4', 'name' => 'number four'),
