Dear All,

I am new to Relational Databases and SQL and my background in ODBs is clouding my way to solving what seems to be a simple problem. I am sure many of you have met it many times.

OK, I have a table as follows:


ID Machine   Date             Withdrawals
1  1              01/01/2003    1101
2  2              01/01/2003    2101
3  3              01/01/2003    3101

4  1              02/01/2003    1102
5  2              02/01/2003    2102

6  1              03/01/2003    1103
7  3              03/01/2003    3103

8  2              04/01/2003    2104
9  4              04/01/2003    4104

And i would like to create a monthly withdrawals report as follows:

Machine   Day1  Day2  Day3  Day4 .............................................. Day31
1             11      12      13       0                                                      0
2             21      22      0        24                                                     0
3             31      0        33       0                                                      0
4              0        0       0         0                                                     0

Can you please help?

Many thanks in advance.

Ali
