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!
