Subject setting column to NULL
Date Wed, 20 Jun 2012 16:55:18 GMT
Hello,

It seems that running the following SQL statement results in an error in Derby, while it's
working fine in other DBs (such as Oracle or Sybase):

select
   a as "ColumnA",
  null as "ColumnB"
from SomeTable

java.sql.SQLSyntaxErrorException: Syntax error: Encountered "null" at line 10, column 2.

Is this by design? And is there a work-around? What needs to be done to set a column to null?

Thank you,
Pavel.
