Inserting Data into Multiple Tables Simultaneously
The question involves inserting data into two separate tables, visits and registration, in a single query. The desired result for the insertion process is as follows:
INSERT INTO `visits` as v ,`registration` as v (v.`visit_id`,v.`card_id`,r.`registration_id`, r.`type`, r.`timestamp`, r.`visit_id`) VALUES (NULL, 12131141,NULL, UNIX_TIMESTAMP(), v.`visit_id`);
MySQL Limitations
However, MySQL does not allow you to insert data into multiple tables with a single query. This limitation poses a challenge in achieving the desired goal.
Solution Approaches
To overcome this restriction, two alternative approaches are suggested:
- Execute Separate Queries: The first approach involves executing two separate INSERT queries as a batch. This ensures that the data is inserted into both tables, but it does not provide the atomicity of a single transaction.
- Create a Stored Procedure: The second approach involves creating a stored procedure that contains two INSERT statements. By calling this stored procedure, both insertions can be executed within a single transaction, ensuring data consistency.

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.
