When working with Oracle databases, understanding how to use comments effectively can enhance your database management skills. Oracle allows you to add comments to tables and columns using specific syntax. This helps in maintaining clear documentation for future reference.

Adding a comment to a table is straightforward. You simply use the `COMMENT ON TABLE` statement. For example:

```sql

COMMENT ON TABLE employees IS 'This table contains employee details.';

```

Similarly, adding a comment to a column involves specifying the column name after the table name. Here's an example:

```sql

COMMENT ON COLUMN employees.id IS 'Unique identifier for each employee.';

```

These comments are stored in the data dictionary and can be viewed using the `USER_TAB_COMMENTS` and `USER_COL_COMMENTS` views. 😊 Using comments not only makes your database more understandable but also aids in debugging and collaboration among team members. Remember, well-documented databases are easier to maintain and modify over time. 🚀

So next time you're working on an Oracle project, don't forget to utilize this handy feature! 💻✨
