Re: Change IN parameter in Procedure
Here are the rules about IN parameters:
A formal IN parameter acts like constant. It can not be assigned with new values.
An actual IN parameter can take a value or a variable.
An actual IN parameter is passed by reference to the specified value or the value of the specified variable.
An actual IN parameter will not receive any value from the formal parameter.
If you try to change in parameter value inside a procedure it will through error message
expression 'XX' cannot be used as an assignment target
