2021 Guide On Oracle SQL Developer

Oracle is, by far, one of the most prominent technologies for application development. This prominence is highlighted more with its most recent version of the Oracle SQL Developer. The software makes Oracle Database development and management seamless both traditionally and through the Cloud. This free software includes:

  • A way to complete application development (in PL/SQL) from start to finish
  • An query / script worksheet
  • A database administration (DBA) console
  • Reports interface
  • An effective data modeling solution, AND
  • A migration platform that allows you to seamlessly move 3rd-party databases to Oracle

In this article, we’ll show you 10 helpful tips on how to effectively use the Oracle SQL Developer:

  1. Set Your Preferences

With many options at your disposal, you’ll only need to take advantage of some of them in Oracle SQL Developer. Regardless if you already know the ropes to the software, or if you’re new to it, it’s important to make the necessary adjustments in your settings, as you use it.

  1. Run Queries Sequentially And Concurrently

With SQL Developer, you’ll need to run multiple queries, either sequentially or concurrently. Let’s look closer at the two methods:

  • A sequential method implies that you select as many queries as desired, and then hit “Ctrl+Enter.”
  • The concurrent method, on the other hand, requires you to run 2 or more queries at the same time, provided that each query has its own connection.
  1. Disable Unused Extensions

Extensions on your computer can interfere with your application development project, because they take up space on your hard drive. So, before running SQL Developer, disable unused extensions, so that the software’s performance is smoother and faster with a friendlier user interface (UI).

  1. Query-Output Formatting

With SQL Developer, you can format the Query Output directly to the following places:

  • CSV (Comma-separated values)
  • HTML (HyperText Markup Language)
  • XML (Extensible Markup Language), etc.

Whether you use the Export wizard for your query result sets is up to you. However, in the case that you don’t know much about the Export wizard feature, you can always add the SQL Developer output hints to automatically format.

  1. Search And Replace

The Search and Replace feature is another key part of the SQL Developer. If you need to find something in the database, you can do so in the following steps:

  • First, use “Ctrl+F” in a model to open a search.
  • Next, go to “Advanced.”
  • Then, set a search area, along with the criteria for said search.
  • Hit “Search.”
  • Afterwards, save your results as a report, or change up the properties across said results.
  1. Know The Versions You’re Using

Although past versions may be irrelevant now, you should still consider the fact that Java will need to be updated as well. (Java 8 update 200+ or Java 11 update 7 are acceptable, in this case.)

  1. Drag-And-Drop Tables To Worksheets And Relational Models

Worksheets and relational models can be accessed in drag-and-drop tables on SQL Developer. Toggling over to the Query Builder can take off columns you don’t need queried, if you join 3 or more tables.

As for relational models, you can drag-and-drop tables with “Ctrl-drag.” (This is called “data modelling.”) By taking tables and reverse engineering them, you can turn them into relational models that can even be printed out or exported to PDF, HTML, and so on.

  1. Data Backups

Like any other software, data backups are essential in SQL Developer. The latest version of the software now implements Cloud Service to make data backups easier than before. In the cloud, you can either duplicate your work or screen them in the Oracle Database.

  1. Get Licensed

You’ll also need to check if your SQL Developer is licensed. Keep in mind: A licensed version of this software comes with offers that might not be beneficial to you. Instead, ensure that you’re using the current version. Should you work with licensed software, make sure you know what you’re getting into.

  1. Utilize Shortcut Keys

Shortcuts are great for those who want to work in the software on the fly. The good news is, you can customize your shortcut keys by configuring them in your settings.


Oracle SQL Developer is great for application development. We hope that this quick guide, with its 10 tips, will help you to understand how you can use the software to transform your next app development project!
