Damn, what does that mean dude?

select distinct na.ARTICLE_ID, na.ART_AUTHOR, na.ART_TITLE, na.ART_CONTENT, na.ART_STARTDATE, na.ART_ENDDATE, na.ART_PHOTO, na.ART_SUBMITTED, nu.USER_USERNAME from news_article AS na inner join news_user AS nu on nu.user_id=na.art_author inner join news_artcats AS nc on nc.artcat_art=na.article_id inner join news_category AS nwc on nwc.category_id=nc.artcat_cat where nu.user_id=na.art_author and nu.USER_USERNAME='satpal'

what it says.

what database do you use ?

MS SQL server

so i cant use a simple distinct on sql server?

never used ms sql server.
but in access, you can use it. Though maybe not on immae variables (like the photo in your query)

also, when using a join, i always go for distinctrow in stead of distinct. (Each combination of values must then be unique)
