How to Enable Line Numbers in SQL Developer
Показать описание
In this video, we’ll look at how to enable line numbers in SQL Developer.
Line numbers are the numbers next to the code editor that tell you what number each line is, starting with 1 and working down. They are common in IDEs in all languages.
When you install SQL Developer (or rather, download it, as it doesn’t need to be installed specifically), the line numbers are turned off by default.
Why would you want to turn them on?
Well, they are really helpful for debugging. When you get an error message, you’ll be given a line number. This refers to the line number in your SQL query that caused the error. With line numbers enabled in SQL Developer, you can see where the error comes from.
Watch the video to learn how to turn on line numbers.
