The PL/SQL WHILE Loop. The WHILE loop, also called a conditional loop, evaluates a condition before each loop executes, and if false, the loop is terminated. If the expression is false when the program reaches the WHILE loop, the loop code is jumped and never executed.Use a WHILE loop when the condition test is required at the start of the loop. The next example contains three WHILE loops.The last loop will never execute because the condition will never be true. The middle loop uses multiple condition tests, using the AND key word.se a WHILE loop when the condition test is required at the start of the loop. The next example contains three WHILE loops. The last loop will never execute because the condition will never be true. The middle loop uses multiple condition tests, using the AND key word.
Using else Statement with Loops. Python supports to have an else statement associated with a loop statement. If the else statement is used with a for loop, the else statement is executed when the loop has exhausted iterating the list.If the else statement is used with a while loop, the else statement is executed when the condition becomes false.The following example illustrates the combination of an else statement with a for statement that searches for prime numbers from 10 through 20.f the else statement is used with a for loop, the else statement is executed when the loop has exhausted iterating the list. If the else statement is used with a while loop, the else statement is executed when the condition becomes false.
