What you wrote will return "-1" True
--------
select ((48 \ 16) mod 2)
if this returns 1 then the number contains bit which represent number 16.
--------
select (48 & 16)
should return 16 in MSSQL
what about under MSAccess
select (48 and 16) this is equal to: select (true and true) and result is true
returns "-1" true, not 16 as i would expect
How to do bitwise integer operations in MSAccess?
ezicoder,
Jet Engine not provides bitwise operator like youz want it. VBA itself is doing this: I check your examples with the following solution:
Create a Public Function in a code modul liek this:
Public Function AddBinary(Value1 As Integer, Value2 As Integer) As Integer
AddBinary = Value1 And Value2
End Function
Than create a new Query in ACCESS with the following SQL:
SELECT AddBinary(48,16) AS MyCalValue;
Run the Query and you will get 16 for 48 AND 16.
