एक चुनिंदा क्वेरी में दो तालिकाओं के समान फ़ील्ड नामों के बीच अंतर कैसे करें?

बस ऐसे ही लिखें,

select a.field1 as af1,a.field2 as af2,a.field3 as af3,b.field1 as bf1,b.field2 as bf2,b.field3 as bf3,c.field1 as cf1,c.field2 as cf2,c.field3 as cf3 from table A as a, table B as b,table C as c where so and so.
