Do you Know?

04 Oct

Hi All,

Could anyone give me the answer for the below question…

Which one of the following is a fundamental difference between while loops & numeric for loops in oracle ?

1.while loops cannot be based on numeric conditions;numeric for loops are always based on numeric conditions;
2.The number of iterations a while loop makes  is unknown or not specified;numeric for loops are designed to loop a specific no of times.
3.while loops depend on the state of the variable and terminate when the state changes;numeric for loops do not.
4.when numbers are used in while loop,they are actually character data;numeric for loops use binary_integer values.
5.while loops terminate  explicitly;the termination of numeric for loops is stated implicitly.
