		Define the list of types to be associated with the columns of a given  result set.
This function may be called before invoking fetchRow(), fetchOne()  fetchCole() and fetchAll() so that the necessary data type  conversions are performed on the data to be retrieved by them. If this  function is not called, the type of all result set columns is assumed  to be text, thus leading to not perform any conversions.

If this array        contains less types than the number of columns that are returned        in the result set, the remaining columns are assumed to be of the        type text. Currently, the types clob and blob are not fully        supported.
