SQL Select distinct values from multiple tables -


so here's setup have 2 tables old , new following (simplified) schemas

old [manname] [mannumber]  new [manager_name] [manager_number]

i'm looking craft sql query returns following in 4 columns in 1 query opposed 2 queries 2 columns each 

select distinct manname, mannumber old  select distinct manager_name, manager_number new

so ideal result set have 4 columns: 

manname mannumber manager_name manager number

thanks!

have tried join statement:

select distinct *  old join new b on a.manname = b. manager_name , a. mannumber = b. manager_number
