There are some suggestions and precautions to help you work more efficiently when using Cursor ai:
1. Suggestions for using Cursor when encoding
Quick navigation: Use keyboard shortcuts (such as Ctrl + → or Ctrl + ← to quickly jump in code to improve editing efficiency.
Select text: Use the Shift key combined with the cursor to quickly select text and reduce mouse operations.
Code collapse and expansion: Use the folding function in complex code to quickly collapse or expand code blocks through Cursor for easy code management.
3. Notes on using Cursor in the database
Cursor is used to process query results row by line in database operations, but the following points should be paid attention to when using it:
Avoid unnecessary Cursors: Cursors have relatively low performance, try to use SQL batch operations or collection processing methods, and reduce the use of Cursors.
Close Cursor in time: After using Cursor, ensure that it is closed in time, release database resources, and avoid memory leakage.
Optimized query: When Cursor processes large amounts of data, make sure SQL queries are optimized to reduce database load.
4. Use Cursor plugin or function in the code editor
Many modern code editors (such as VS Code, IntelliJ IDEA, Sublime Text, etc.) have Cursor plug-ins or related features. Here are some recommended practices:
Multi-cursor editing: Use multiple cursors to edit multiple positions at the same time, which is suitable for batch modification of similar codes.
VS Code: Alt + Click (place the cursor in multiple locations)
Sublime Text: Ctrl + Click
Jump to definition/reference: Use F12 to jump to function or variable definitions to improve code reading and understanding speed.
Intelligent Completion and Recommendations: Ensure that intelligent Completion is enabled and improve code writing efficiency.
5. Common Errors and Precautions
Overuse of Cursor: Using Cursor in unnecessary situations can lead to code confusion or performance degradation, especially in database operations.
Ignore Cursor Close: Forgot to close Cursor during database operations will cause the connection resources to be not released, affecting database performance.
Improper use of multi-cursors: While multi-cursors can improve efficiency, improper use may introduce errors, ensuring a clear understanding of all modified codes.
6. Cursor best practices
Simplify the code structure: When using Cursor, try to simplify the code structure as much as possible to avoid overly complex Cursor operations.
Test and debug: Frequently test code or database operations to ensure that Cursor operations do not introduce errors.
Read Documents: Read documentation for the database or code editor you use, learn about best practices and limitations.
