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.
