Granting Privileges Except for a Specific Table
In MySQL, you can encounter situations where you need to grant a user extensive privileges on a database, but with the exception of a specific table. This can be achieved, but requires a more granular approach compared to granting "ALL" privileges.
To resolve this issue, you can individually grant various privileges on each table within the database, excluding the desired read-only table. For instance, you could grant the user privileges such as "INSERT," "UPDATE," "DELETE," and "SELECT," but exclude the "UPDATE" privilege from the table that should be read-only.
Here's how you can achieve this:
- Revoke all existing privileges from the user on the target database. This ensures a clean slate for resetting privileges.
- Use the GRANT command to grant individual privileges on each table. For example:
<code class="mysql">GRANT INSERT, DELETE, SELECT ON db_name.table1 TO user@localhost;</code>
- Create a separate GRANT statement for each table in the database, excluding the one that should remain read-only.
- Execute each GRANT statement in sequence.
- Check the user's privileges using the SHOW GRANTS command to verify the changes.
You can also use tools like MySQL Workbench or phpMyAdmin to manage user privileges and grant specific permissions on tables and databases. These tools provide a more convenient interface for setting up permissions and allow you to visually view the privileges granted to each user.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
