Hello everybody!

I have a mysql table with these columns:

ID (auto-increment)
ID_BOOK (int)
PRICE (double)
DATA (date)

I know two ID_BOOK values, example, 1 and 2.

QUERY:

I have to extract all the PRICE (of the ID_BOOK=1 and ID_BOOK=2) where DATA is the same!

Table example:

1  1  10.00  2010-05-16

2  1  11.00  2010-05-15

3  1  12.00  2010-05-14

4  2  18.00  2010-05-16

5  2  11.50  2010-05-15

Result example:

1  1  10.00  2010-05-16

4  2  18.00  2010-05-16

2  1  11.00  2010-05-15 

5  2  11.50  2010-05-15

ID_BOOK=2 hasn't 2010-05-14 so i jump it.

Thank you so much!
