Problem with Logical Operators

[Jose Osman Sansuste Tapia]

Hello, i'm trying to do some query using Logical Operators like SQL SERVER, but in my SQL soesnt work like SQL SERVER.

When i use in SQL SERVER this query:

SELECT * FROM Parametros.dbo.niveles_accesos
WHERE (nvl_codigo & 8) = 8

it compares the column nvl_codigo with the 8, and shows me all the results that are = 8

But in MySQL if i use && always return 1 o 0, and never the number i was looking for return (in this case 8)

How do i make my query in MYSQL to get the same result that SQL SERVER?

THANKS...
