TABLE FUNCTION returning CHAR values does not return a correct value if the 
Java ResultSet class returns a value less than the length of the defined CHAR.

                 Key: DERBY-3341
                 URL: https://issues.apache.org/jira/browse/DERBY-3341
             Project: Derby
          Issue Type: Bug
          Components: SQL
            Reporter: Daniel John Debrunner
             Fix For: 10.4.0.0


Defining a column in the returned type as CHAR(10) requires that the returned 
value be of length 10 characters.

Defining a table function with a return type of:
   returns TABLE  column0 char( 10 ), column1 char( 10 ))
seems to just return whatever the Java ResultSet implementation handed it.

My guess this is true for all variable length types, no casting of the value 
occurs when it is returned to the SQL domain.

Java single value functions and procedure out parameters do perform any 
required casting to ensure the value is of the declared type.
