Reverse a Number in PL/SQL
PL/SQL is a block-structured language that combines SQL's functionality with procedural commands. In this article, we will discuss a program in PL/SQL to reverse a given number for example −
Input : 98765 Output : 56789 Explanation : reverse number of 98765 is 56789. Input : 56784 Output : 48765 Explanation Reverse number of ‘56784’ is ‘48765’.
Approach to find The Solution
- Take out the last digit from the number by finding the remainder of num/10.
- Now add the last digit to another variable reversed_num.
- Now check if num becomes 0 −
- If YES, then go to STEP1.
- If NO, then go to STEP4.
- Finally, print the reversed_num.
Example
DECLARE num number; reverse_num number:=0; begin num:=98765; while num>0 loop reverse_num:=(reverse_num*10) + mod(num,10); num:=trunc(num/10); end loop; dbms_output.put_line(' Reversed number is : '|| reverse_num);
Output
Reversed number is: 56789
Conclusion
In this article, we discuss the PL/SQL programming language, which is very simple to use; it feels like using ordinary English to command the system. We also discussed a problem of reversing a number in PL/SQL language. We hope you find this article helpful.
