If it's 1 to N, it can find multiple corresponding rows instead of just one. mvg/regards Jo Nuno Souto <dbvision@xxxxxxxxxxxxxxx> Sent by: oracle-l-bounce@xxxxxxxxxxxxx 07/23/2004 16:06 Please respond to oracle-l To: oracle-l@xxxxxxxxxxxxx cc: Subject: Re: Quick question re outer joins jo_holvoet@xxxxxxxx apparently said,on my timestamp of 23/07/2004 6:50 PM: > If the relationship to the new table is 1-N, it could potentially add rows > just like a regular join, couldn't it ?
