Sql query need

I have 3 tables Table1 and Table2 and Table 3 with following data
Table 1
A
1
2
3
4

Table 2
A B C
1 1 1
2 1 2
3 1 5
4 1 3

Table 3
B C D
1 2 0
1 1 0
1 3 0
1 4 0

Select all A from Table1 and Select B, C from Table2 where Table1.A=Table2.A

After this we will get some result with B and C. Finally these B and C should compare with table3 fields B and C if B and C is same then should update Table3.D to ’1’

So please tell me the correlated query for this

After the query Table 3 should look like this
Table 3
A B C
1 2 1
1 1 1
1 3 1
1 4 0

Thanks in advance
kiran

I assume the final outout should be Column B C D and not A B C as you mentioned above.

Try this Query

UPDATE Table3
SET D = (CASE D IS NOT NULL THEN 1 ELSE 0 END)
FROM Table1
INNER JOIN Table2 ON Table1.A = Table2.A
LEFT OUTER JOIN Table3 ON Table2.B = Table3.B AND Table2.C = Table3.C

GO

SELECT B,C,D
FROM Table3
