PL/SQL DataType: Program to show the uses of SIMPLE_INTEGER datatype

PL/SQL DataType: Exercise-6 with Solution

Write a PL/SQL program to show the uses of SIMPLE_INTEGER datatype.

Sample Solution:

PL/SQL Code:

DECLARE
  num SIMPLE_INTEGER := 2147483645;
BEGIN
  FOR j IN 1..4 LOOP
    num := num + 1;
    DBMS_OUTPUT.PUT_LINE(TO_CHAR(num, 'S9999999999'));
  END LOOP;
  FOR j IN 1..4 LOOP
   num := num - 1;
   DBMS_OUTPUT.PUT_LINE(TO_CHAR(num, 'S9999999999'));
  END LOOP;
END;
/

Flowchart:

Sample Output:

+2147483646
+2147483647
-2147483648
-2147483647
-2147483648
+2147483647
+2147483646
+2147483645

PL/SQL procedure successfully completed.

In the above example the initial value is 2147483645, when this value reach in upper limit it started from starting value.
