To connect to a server in Navicat, you need to know the server address, port, username, and password. 1) Enter these details into the connection wizard; 2) Adjust settings according to the database type, such as MySQL's SSL options; 3) Use Navicat's multi-connection function to manage multiple databases at the same time; 4) Save connection configuration files for reuse; 5) Use SSH tunnels to enhance connection security.

Navicat does store your credentials. 1) Navicat saves database connection information to local files, improving work efficiency, but also causing security issues. 2) To meet security challenges, Navicat provides master password encryption and SSH/SSL/TLS encryption protection. 3) Users should change their master passwords regularly, use strong passwords, and ensure the safety of their computers.

The key to mastering the code completion function is to be familiar with the triggering method, use the context to improve accuracy, and choose the right completion engine. 1. Different editors have different triggering methods. They can be triggered by input points or shortcut keys such as Ctrl/Cmd Space, or they can rely on language plug-ins to automatically pop up suggestions; 2. Enhance context understanding through standardized naming, using type annotations, avoiding confusion of variable types, etc., making recommendations more accurate; 3. Installing advanced completion engines such as GitHubCopilot, Pylance, or using IDEs with intelligent completion such as JetBrains can greatly improve efficiency. After using these techniques well, code completion will become an indispensable tool for efficient programming.

The key to managing multiple Navicat instances is to organize the connection grouping rationally, use color tags to distinguish the environment, and use batch operations to improve efficiency. 1. Classify the connections into different groups by purpose (such as development, testing, production), and adopt clear naming rules to facilitate quick positioning; 2. Set a unified color label for each group of connections (such as red represents production library and green represents development library) to prevent misoperation; 3. Use functions such as "batch opening connection", "structure synchronization" and "run SQL files" to achieve efficient batch processing, and pay attention to confirming the target database and making backups before operation.

Although Navicat does not have an independent command history panel, you can view executed SQL statements in the following ways: 1. Use the "History" function to view recently executed SQL, click the "History" button in "Query" or "SQL Editor"; 2. Enable the logging function, set the log path and level through "Tools > Options > Log Files", record all operations for easy audit; 3. If automatic backup or version control (such as Git) is enabled, old SQL content can be retrieved from the backup file or submission history.
