rename *- rename a class or an attribute in a class
rename classname1 to classname2 rename attname1 in classname to attname2
The rename command causes the name of a class or attribute to change without changing any of the data contained in the affected class. Thus, the class or attribute will remain of the same type and size after this command is executed.
/* change the emp class to personnel */ rename emp to personnel /* change the sports attribute to hobbies */ rename sports in emp to hobbies
Execution of historical queries using classes and attributes whose names have changed will produce incorrect results in many situations.
Renaming of types, operators, rules, etc. should also be supported.
