Re: selecting everyting from 2 non-identical tables.
My frist post was not worded correctly. I cannot join two tables as all the rows are unique. men id height name age fav team 1 - 176cm - John - 25-lakers 2 - 180cm - Rob - 40-yankies women id height name age no_of_children 3 - 166cm - mary - 22 - 2 4 - 175cm - betty - 48 - 4 I want to display all the attributes of all the people even if they are null my final table should be 1 - 176cm - John - 25-null-lakers 2 - 180cm - Rob - 40-null-yankies 3 - 166cm - mary - 22 - 2-null 4 - 175cm - betty - 48 - 4-null Ross - Original Message - From: "Jay Blanchard" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]>; Sent: Tuesday, June 19, 2007 12:58 PM Subject: RE: selecting everyting from 2 non-identical tables.
