I want to append a new column in the fashion of
public CachedRowSet addColumn(cachedRowSet Original,List<item> column, String columnName);
or
public CachedRowSet addColumn(cachedRowSet Original,int column,String columnName);
with the column value repeated if it is a primitive.
What is the best way to do this?
Hmm.. hard to answer without knowing the context. Who is providing that CachedRowSet? They might or might not offer a way to generate a new instance. Are you using CachedRowSetImpl from the RI?
The RowSet is not really intended for that. Can you add it to the generating SQL? SELECT a,b,'additional' from ...
. Or you can use your CachedRowSet and generate JoinedRowSet with a FULL_JOIN with a single field result set.
