Error in DatabaseMetaData.getColumns() with Views

Hi, I wish to report a erroneous information returned by   DatabaseMetaData.getColumns()  method.

This happens with ResultSet's column (7) COLUMN_SIZE  and  (9) DECIMAL_DIGITS ,
when DatabaseMetaData.getColumns() inform about a VIEW with columns formed with :
coalesce , case or numeric operations over DECIMAL fields.

Suppose

CREATE TABLE A (  f1 DEC(6,3), f2 dec(6,3) );
CREATE VIEW B as ( select ( f1 + f2 ) as f from a;

Then DatabaseMetaData.getColumns() returns:

VIEW B
    F   NUMERIC(  65535 ,  -65531 )

This error its very molest because if you are trying to do CodeGeneration from DatabaseMetaData.

Any suggestion will be appreciated.
Best regards,
Dario Fassi
