please check your setting of NLS_NUMERIC_CHARACTERS:

it is likely defining the "." as decimal, and "," as thousand separator.

Check the session parameters NLS_NUMERIC_CHARACTERS.

It may be the case that you are using ',' as a group seperator.

What is the output of following? (Need to to login with sysdba privilege)

select * from nls_database_parameters where parameter like '%NUMERIC%';
select * from nls_session_parameters where parameter like '%NUMERIC%';
select * from nls_instance_parameters where parameter like '%NUMERIC%';

Are you running both the statements in different sessions? Please confirm.

Also, are you getting error ORA-1722 when you update?

In that case update will fail anyways.

What is the value of x before the update? Is it 3433?

Please confirm...
