Subject: Help with Join SQL

I need to convert the following Oracle specific code to standard SQL (LEFT OUTER JOINS?)

           
            from tab1,tab2,tab3 
            where 
               tab1.customer(+) = tab3.customer and 
               tab2.customer(+) = tab3.customer ;

Can anyone help?
