I have a situation where I need to update dates in a primary table from regular imports of data, eg: this is the base select query
select d.row_id, fname||lname,'joineddate',d.joineddate,'joineddate',s.joineddate,0 as bool1 from import s join members d on d.contact_id=s.contact_id where
cast(nullif(d.joineddate,NULL) as timestamp) != cast(nullif(s.joineddate,'') as timestamp)
This gives zero records, however I cant seem to get a query that works.
For non-date fields I just use Coalesce(fieldprime,'')!=coalesce(fieldiimport,'') which works fine but chokes on dates where there is a blank value
thanks in advance
