Re: set JdbcTypes for only one column

[Jakob Braeuchi]

hi carlos,
with the current versions of ojb you can only set the types for all 
columns.

there are imo two ways to set the type of a specific column:
1.) pass the whole array of types but define a type to be ignored
as the parameter is an array of int we cannot use null, so we need to 
define an intvalue that is ignored.

2.) provide an additional method which allows to set the type for a 
single column only.

 Hi to all.
 is posible to set the jdbcTypes for only one column of the result of the
 query ?
 I know we can use the methode setJdbcTypes, but this need set the datatypes
 for all columns, i want to do this for only two columns, is this posible?.
 I try to do this:
 SELECT INVOICE_NUM, null AS USER1, null AS USER2 FROM INVOICE
 The problem is when the OJB try to convert the value for a
 java datatype, i think.
 the error are:
 Exception in thread "main" java.lang.NullPointerException
