Question : Unary and bitwise operators

Hi all,

the SQL book says following:

"Unary Performs an operation on only one expression of any of the data
types of the numeric data type category
Bitwise Temporarily turns a regular numeric value (such as 150) into an
integer and performs bitwise (0 and 1) arithmetic"

Can someone please give me a two simple examples of unary and bitwise operators that can be used in SQL Server?

cheers,

henrik

Answer : Unary and bitwise operators

bitwise NOT
   select ~(254) -- ===  -255
   A bitwise unary operator (only takes one argument)

select sqrt(81)
   A unary operator (only takes one argument)
   (nothing to do with the binary value)

Bitwise OR
   select 8 | 5 === 13
   A binary operator (takes two arguments ... left and right )

Multiplication
   select 123 * 456 --- == 56088
   Anothor binary operator (nothing to do with bitwise operations)

---

Unary - takes one argument
Binary - takes two arguments
