Valid Expression Types For Operators.

Hi everybody:

I want know where can I find information about valid expresion types for each one of de Arithmetic Operators, Bitwise Operators, Comparison Operators, Logical Operators, Unary Operators in SQL server. I want something like this.

for (+) ADD, syntaxis -> expression + expression

expression Valid? result type
-----------------------------------------------------------------
int + int ok int
int + bigint ok bigint
char + char ok char <- (+) works like concatenation
char + int ok char???
image + bit error -
binary + int ok binary???



for (*) MULTIPLY, syntaxis -> expression * expression

expression Valid? result type
-----------------------------------------------------------------
int * int ok int
int * bigint ok bigint
char * char error -
char * int error -
image + bit error -
binary + int ok binary????

for (<) LESS THAN, syntaxis -> expresion < expression

expression Valid? result type
-----------------------------------------------------------------
int < int ok bit???
char < char ok bit???
char < int ok bit???
image < bit error -

tks for help.
