WHILEconditionLOOPexecutable_statement(s) END LOOP;
A conditional loop that continues to execute as long as the Boolean condition defined in the loop boundary evaluates to TRUE. Use the WHILE loop when you don’t know in advance the number of times a loop must execute. You might also use the WHILE loop instead of the simple loop when you might not want the loop body to execute even once.
