Hello everybody.

I have a table which contains the following data:

DOCUMENT ACCESS
1 1
2 1
3 1
1 2
2 1
3 2
1 3

If I use the sentence "SELECT DOCUMENT, SUM(ACCESS) FROM TABLE" I get:

DOCUMENT ACCESS
1 6
2 2
3 3

And if I use "SELECT DOCUMENT, SUM(DISTINCT ACCESS) FROM TABLE" I get:

DOCUMENT ACCESS
1 6
2 1
3 3

But I need a way to obtain a bitwise addition instead of the arithmetical addition. (bitwise OR).
Something like this: "SELECT DOCUMENT, BIT_OR(ACCESS) FROM TABLE"

DOCUMENT ACCESS
1 3
2 1
3 3

Does anyone know how to do this or how to write an aggregate UDF in Delphi/Kylix to accomplish it?

Please your help.

Thanks in advance.

Saludos,
