Hi Peter, In that case, I’m a little confused. In your query, you have dfs as the storage plugin which is the default storage plugin for the local file system. Did you change that?
What happens if you execute the following queries: SELECT TO_CHAR(table1.product_code, '######') from dfs.vtucare.vw_tbl_transactions as table1 LIMIT 10 SELECT TO_CHAR(table2.product_code, '#####’) FROM dfs.vtucare.vw_tbl_products AS table2 LIMIT 10 Do those queries produce results? —C > On May 28, 2018, at 11:43, Peter Edike <[email protected]> > wrote: > > The query queries a no-sql database....so I don’t think there is type > information.
