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.

                at org.apache.derby.impl.jdbc.EmbedConnection.prepareStatement(Unknown Source)

                at org.apache.derby.impl.jdbc.EmbedConnection.prepareStatement(Unknown Source)

 

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

 

Thank you,

Pavel.
