select b.Booking_id,booked_by,Datetime,FP_no,Name,co_name,

from Booking_details b, av_details av, booking_food_details food
where b.Booking_id=@Booking_id
and b.Booking_id=av.Booking_id
and b.Booking_id=food.Booking_id

Now the problem here is that av_details and booking_food_details have different number of rows,Suppose
booking_food_details has a,b,c and, av_details has d,e,f,g,h

so when I run it with data it shows me 5 lines of entry and av_details rows repeats itself 5 times, like :

booking_food_details av_details
d a
e b
f c
g a
h b
Rather it should display:

booking_food_details av_details
d a
e b
f c
g
h

I want to know what is the impact of INNER JOIN with OUTER JOIN / OUTER APPLY. Also need to know the impact of adding the inner join inside the outer apply instead of using it outside the outer apply

select few_columns
from table1 a
left outer join table2 b
on b.col1 = a.col1
inner join table3 c
on c.col2 = b.col2

or

select few_columns
from table1 a
outer apply
(select col1, col2, col3
from table2 b
where b.col1 = a.col1
)z
inner join table3 c
on c.col2 = z.col2

or

select few_columns
from table1 a
outer apply
(select col1, col2, col3
from table2 b
inner join table3 c
on c.col2 = b.col2
where b.col1 = a.col1
)z

Please let me know the difference in the performance & the resultset

Write query as Select * from tabel1,tabel2

U’ll get the result
