Subquery issue

Subquery issue

 I have a table called STATUS that has a column named BUILD.  The build column is integer and populated with values between and 1 and 6.

The following subquery in a NEW_QUERY_TABLE:

select build from
( select build from status
) subquery

returns the error 'Invalid column 'build' used in SELECT query.'

This is valid SQL that I have tested in PostgreSQL.  Is this unsupported?
