Redo (Reapplying an Undone Action)
The Redo feature allows users to reapply actions that were previously undone. This is especially useful when users accidentally undo an important change and want to quickly restore it. Instead of rewriting or redoing the entire work manually, users can simply use the Redo option to bring back the last undone action. This feature improves productivity and ensures a smooth editing experience.

Undo (Reverting a Previous Action)
The Undo feature helps users easily correct mistakes by reversing the last action performed. Whether it is deleting code, editing text, or making unwanted changes, users can instantly go back to the previous state. This reduces the risk of losing important work and provides a safe environment for experimenting and learning.

Open
The Open feature allows users to access SQL files stored on their device. Users can quickly open previously saved files and continue their work without any interruption. This feature ensures flexibility and convenience, especially when working on multiple projects.

Save
The Save option allows users to store their current SQL code securely. It ensures that all progress is saved and can be accessed later. This is essential for users who are working on complex queries or long-term projects.

Save As
The Save As feature enables users to create a duplicate copy of the current file with a different name. This is useful when users want to experiment with changes without affecting the original file. It helps in maintaining multiple versions of the same code.

Find
The Find feature is a powerful tool that allows users to quickly search for specific words, keywords, or characters within the SQL code editor. Instead of manually scanning through long and complex scripts, users can instantly locate the exact portion of code they are looking for. This feature is especially useful when working with large SQL queries, multiple statements, or lengthy scripts where finding a particular keyword can be time-consuming. It not only saves time but also improves productivity by making code navigation faster and more efficient. Whether you are debugging, editing, or reviewing your code, the Find option ensures that you can access any part of your script with ease and accuracy.

Go to Line
The Go to Line feature provides a fast and convenient way to navigate directly to a specific line number within the code editor. When working with large SQL files, scrolling manually to find a particular line can be difficult and inefficient. With this feature, users can simply enter the desired line number and instantly jump to that location. This is extremely helpful during debugging, error fixing, and code analysis, where precise navigation is required. It enhances the overall coding experience by saving time, reducing effort, and allowing users to focus more on writing and improving their queries.

Reset
The Reset feature is designed to help users quickly clear the entire code and return the editor to its default or initial state. This is particularly useful when users want to start fresh without being affected by previous code or changes. Instead of manually deleting each line of code, the Reset option instantly removes everything, providing a clean workspace. It is ideal for beginners who want to practice multiple queries, as well as for developers who need to test different scenarios without confusion. This feature ensures a smooth and hassle-free coding experience by allowing users to restart their work anytime with just a single action.

Restore
The Restore feature plays an important role in maintaining a safe and controlled learning environment. It allows users to reset the database back to its original state after executing queries that modify or affect the data. This is especially useful for practice and experimentation, where users may run INSERT, UPDATE, or DELETE queries. Instead of worrying about permanent changes, users can simply use the Restore option to bring back the original data. This encourages learning through trial and error without any risk. It ensures that users can repeatedly test queries, understand their behavior, and improve their SQL skills with confidence.

Run
The Run feature is one of the core functionalities of the SQL Code Play app. It allows users to execute the SQL queries they have written and instantly view the output. This real-time execution provides immediate feedback, helping users understand how their queries work and whether they are correct. If there are any errors, users can quickly identify and fix them. This interactive approach makes learning SQL more practical and engaging, as users can directly see the results of their code. It simulates a real database environment, making it ideal for both beginners and advanced users to practice and improve their skills.
