How to print line numbers in PL/SQL

Introduction

Any one who wants to be a good programmer must also acquire good debugging skills. Oracle PL/SQL database programming offers several easy code debugging options through the DBMS_UTILITY package. This article provides some nuances about printing line numbers in PL/SQL code.

In PL/SQL, there isn't a built-in mechanism to automatically print line numbers for code execution like you might find in some other programming languages. However, you can manually add line numbers to your PL/SQL code for documentation and debugging purposes. Here's how you can do it:

plsql
1  DECLARE
2    -- Your PL/SQL code here
3  BEGIN
4    -- Your PL/SQL code here
5  EXCEPTION
6    WHEN OTHERS THEN
7      -- Exception handling code here
8  END;

In the example above, we've added line numbers as comments before each line of code. This can help you keep track of the line numbers for reference and debugging. You can adjust the line numbers as needed for your code.

Additionally, if you are using an integrated development environment (IDE) for PL/SQL development, it may have built-in features or plugins that can display line numbers in the code editor for you, which can be very helpful for tracking errors and debugging.
