PL/SQL procedure successfully completed. use applet code 128b implementation toconnect code 128a on java Code 128 Code Set C 7, Iterative Control: Part II 1) Rewrite script ch06_4a.sq l to calculate the factorial of even integers only between 1 and 10. The script should use a CONTINUE or CONTINUE WHEN statement.

ANSWER: Recall script ch06_4a.sql: SET SERVEROUTPUT ON DECLARE v_factorial NUMBER := 1; BEGIN FOR v_counter IN 1..

10 LOOP. APPENDIX D: Answers to the Try it Yourself Sections v_factorial := v_factorial * v_counter; END LOOP; -- control resumes here DBMS_OUTPUT.PUT_LINE ("Factorial of ten is: ". v_factorial); END;. Next, consider a new version of the script that uses a CONTINUE WHEN statement. Changes are shown in bold. SET SERVEROUTPUT ON DECLARE v_factorial NUMBER := 1; BEGIN FOR v_counter IN 1.

.10 LOOP CONTINUE WHEN MOD(v_counter, 2) != 0; v_factorial := v_factorial * v_counter; END LOOP; -- control resumes here DBMS_OUTPUT.PUT_LINE ("Factorial of even numbers between 1 and 10 is: ".

v_factorial); END; In this USS Code 128 for Java version of the script, you add a CONTINUE WHEN statement that passes control to the top of the loop if the current value of v_counter is not an even number. The rest of the script remains unchanged. Note that you could specify the CONTINUE condition using an IF-THEN statement as well: IF MOD(v_counter, 2) != 0 THEN CONTINUE; END IF; When run, this example shows the following output: Factorial of even numbers between 1 and 10 is: 3840.

Make sure that the output produced by this script does not differ from the output produced by the original script. ANSWER: Consider the original version of the script: SET SERVEROUTPUT ON DECLARE v_test NUMBER := 0; BEGIN <<outer_loop>> FOR i IN 1..

3 LOOP DBMS_OUTPUT.PUT_LINE("Outer Loop"); DBMS_OUTPUT.PUT_LINE("i = ".

i); DBMS_OUTPUT.PUT_LINE("v_ applet code-128c test = ". v_test); v_test := v_test + 1;. APPENDIX D: Answers to the Try it Yourself Sections <<inner_loop>> F OR j IN 1..2 LOOP DBMS_OUTPUT.

PUT_LINE("Inner Loop"); DBMS_OUTPUT.PUT_LINE("j = ". j); DBMS_OUTPUT.PUT_LINE("i awt Code 128 = ". i); DBMS_OUTPUT.PUT_LINE("v_ test = ". v_test); END LOOP inner_loop code128b for Java ; END LOOP outer_loop; END;. Next, consider a modified ve rsion of the script that uses simple and WHILE loops. Changes are shown in bold. SET SERVEROUTPUT ON DECLARE i INTEGER := 1; j INTEGER := 1; v_test NUMBER := 0; BEGIN <<outer_loop>> LOOP DBMS_OUTPUT.

PUT_LINE ("Outer Loop"); DBMS_OUTPUT.PUT_LINE ("i = ". i); DBMS_OUTPUT.PUT_LINE ("v servlet code128b _test = ". v_test); v_test := v_test + 1;. -- reset inner loop counter Code128 for Java j := 1; <<inner_loop>> WHILE j <= 2 LOOP DBMS_OUTPUT.PUT_LINE DBMS_OUTPUT.PUT_LINE DBMS_OUTPUT.

PUT_LINE DBMS_OUTPUT.PUT_LINE j := j + 1; END LOOP inner_loop;. ("Inner Loop"); ("j = ". j); ("i = ". i); ("v_test = ". v_test);. i := i + 1; -- EXIT conditio n of the outer loop EXIT WHEN i > 3; END LOOP outer_loop; END;. Note that this version of th code 128 barcode for Java e script contains changes that are important due to the nature of the loops that are used. First, both counters, for outer and inner loops, must be declared and initialized. Moreover, the counter for the inner loop must be initialized to 1 before the inner loop is executed, not in the declaration section of this script.

In other words, the inner loop executes three times. It is important not to confuse the phrase execution of the loop with the term iteration. Each execution of the.

APPENDIX D: Answers to the Try it Yourself Sections WHILE loop causes the statem Code 128 for Java ents inside this loop to iterate twice. Before each execution, the loop counter j must be reset to 1 again. This step is necessary because the WHILE loop does not initialize its counter implicitly like a numeric FOR loop.

As a result, after the first execution of the WHILE loop is complete, the value of counter j is equal to 3. If this value is not reset to 1 again, the loop does not execute a second time. Second, both loop counters must be incremented.

Third, the EXIT condition must be specified for the outer loop, and the test condition must be specified for the inner loop. When run, the exercise produces the following output:. Outer Loop i = 1 v_test = 0 Inner Loop j = 1 i = 1 v_test = 1 Inner Loop j = 2 i = 1 v_test = 1 Outer Loop i = 2 v_test = 1 Inner Loop j = 1 i = 2 v_test = 2 Inner Loop j = 2 i = 2 v_test = 2 Outer Loop i = 3 v_test = 2 Inner Loop j = 1 i = 3 v_test = 3 Inner Loop j = 2 i = 3 v_test = 3 PL/SQL procedure successfully completed..
