datagridview - .NET dataadapter returns duplicate records when actual SQL returns as expected -


populating datagridview sourced dataadapter, duplicate records -- there aren't duplicate records in database (sql server 2008). when run same sql in ssms query window results normal (no duplicates). i'm using "select distinct" statement (no outer-joins)

are there settings prevent duplicate records in dataadapter? don't want remove duplicates manually (as i've seen in discussions, that's wrong). it's straight forward, nothing returned db that's duplicate, yet somehow they're showing up. can't duplicate in development env, occurs in 1 specific running instance of application.
