Select statement for statistical use

I have a table with two rows, a date and a number:

2011-01-01, 45
2011-03-01, 50
2011-03-01, 55

The output I need is:

January, 45
February, 0
Mars, 105

Closest i get is with this select:
SELECT MONTHNAME(date), SUM(number) FROM tableA

GROUP BY MONTH(date)

This gives me:

January, 45
Mars, 105

February is missing - and i need it to feed a diagram.

Hi Sunsales,,

I might be missing something here but the examples you give seem to be correct.

In your sample table data you have two entries for the month of March

2011-03-01, 50
2011-03-01, 55

and your result set shows a total of 105 for March.

Surely the fix would be to edit the source data?

Hope this make sense,

Mark.
