Hello

My DataBase is Paradox.

And I have 3 tables

table 1:

ID    BeignDate   Price
1      1-1-2001      1.21
1      1-2-2001      5.21
1      2-2-2002     10.22
2      5-5-2002     22.22
3      2-2-2002      1.11

table 2:
ID    BeginDate   Correction
1     1-3-2001      -.50
1     1-4-2001      +.10
2     1-1-2002      -.02
5     6-6-2002     10.01

Table 3
ID   Name
1    A
2    B
3    C
4    D
5    E

I want to select The LAST Price for each ID
Price := Price + Correction

The Result Table:

ID Last Price
1       10.32
2       22.20
3        1.11
5       10.01

Can anybody help me with SQL Statement?

Thanks.

HI,
Try this:
SELECT A.ID, A.PRICE+B.CORRECTION AS LASTPRICE  
FROM TABLE1 A
JOIN TABLE2 B ON B.ID=A.ID
WHERE (A.BEGINDATE=
        (SELECT MAX(BEGINDATE) FROM TABLE1
         WHERE ID=A.ID))
AND
        (B.BEGINDATE=
        (SELECT MAX(BEGINDATE) FROM TABLE2
         WHERE ID=B.ID))

If everything will be good - fine, if not - inform me.
Sincerely,
Nestorua.

Thanks! :)))

This is good but there is one problem.

Look at row 4 in Result table where ID = 5!
ID = 5 exist in table 2 but NOT exist in table 1 :)

Thaks againg.

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

... and what about  Table 3? Can you put the NAME of ID in the result table?
