> 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.
