Navicat's code snippet function can be set and used in the following steps to improve efficiency: 1. Find the "Code Snippet" panel on the left side of the query editor. If it is not displayed, it will be enabled through "View>Code Snippet"; 2. You can create folders to classify the fragments, such as reports, data cleaning, etc.; 3. Add custom fragments to right-click the panel to select "Add Code Snippet" or "Add Folder", enter the name and paste the code; 4. The fragments are stored by database type, and they must be configured separately by MySQL, PostgreSQL, etc.; 5. Use drag and drop to quickly insert the fragments into the query editor; 6. It is recommended to use placeholders in the fragments for subsequent modification, keep the fragments concise, and update the fragment content regularly, and can be exported/derived.

The steps to create an index for a table in Navicat are as follows: 1. Open Navicat and connect to the database; 2. Find the target table and right-click to select "Design Table"; 3. Switch to the "Index" tab and click the " " to add an index; 4. Fill in the index name, select fields, sorting method and type (such as UNIQUE, FULLTEXT); 5. Save settings. Indexes can improve query speed and are suitable for fields that are frequently searched or sorted, but are not suitable for fields that are frequently updated or have many duplicate values. Common types include ordinary index, unique index, primary key index, combined index and full-text index. You should select appropriate index types and fields according to actual query requirements, and pay attention to the leftmost matching principle of combined indexes and avoid redundant indexes.

In Navicat, specific permissions can be assigned to users through a graphical interface. First, create or select users and set host access permissions; second, select database or table-level permissions in the user editing page, and check specific operation permissions such as SELECT and INSERT; you can also execute GRANT commands through the SQL query window to achieve more flexible authorization; finally pay attention to saving changes and refreshing permissions to ensure that the permissions are fine and there are no security risks.
