Welcome to the CodeRanch!

Similar issue might worth to look at...

And please make sure to use code tags when posting code in the forums. I've done it for you this time...

I am running this Query :

List<Object[]> metadataList1 = session.createSQLQuery("select t2.name from sys.objects t1 inner join sys.columns t2 on t1.object_id=t2.object_id").list();

Where is the issue?

[aswini nayak]

Explicitly cast and worked

String myquery = "select cast(t2.name as varchar) column_name from sys.objects t1 inner join sys.columns t2 on t2.object_id = t1.object_id"+
" left join sys.indexes t3 on t3.object_id = t1.object_id and t3.is_unique = 1 left join sys.index_columns t4 on t4.object_id = t1.object_id and t4.index_id = t3.index_id and t4.column_id = t2.column_id where (upper(t1.type) = 'U' or upper(t1.type) = 'V') and upper(schema_name(t1.schema_id)) = 'dbo' and upper(t1.name) = 'TEST'";
