Hi,OUT parameter will be useful for returning the value from subprogram, value can be assigned only once and this variable cannot be assigned to another variable.IN OUT parameter will be used to pass the value to subprogram and as well as it can be used to return the value to caller of subprogram. It acts as explicitly declared variable. Therefore it can be assigned value and its value can be assigned to another variable.So IN OUT will be useful than OUT parameter.

1) IN OUT and OUT selection criteria depends upon the program need.if u want to retain the value that is being passed then use seperate (IN and OUT)otherwise u can go for IN OUT.2)If nothing is assigned to a out parameter in a procedure then NULL will be returned for that parameter.

1.There is no hard and fast rule about this. Whether to use INOUT or OUT depends upon the situation.

2. If not assigned anything to OUT parameter it retuns NULL value.

In parameter means it will insert the values
OUT parameters means it will print out put (pass values to output). If we not assigning any value to out parameter it will take (print) NULL value.

INOUT means it take values as input and out put
