Hi ,

1. What is the maximum no of columns you can have in a composite primary key.
d.none of above

2. Which of the following is true ?
a. we should not specify size of the datatype of the parameter in procedure
b. we should not specify size of the datatype of the parameter in function.
c. both a and b.
d. none of above.

3.What is the result when an arithmetic operationis carried out with null

a. error
d.none of above

4.what is the latest date that can be obtained from oracle ?

Looks like easy questions , but little tricky and can cause confusion.

Let me know of your views.
