Obtaining the Next Auto-Increment ID in MySQL
Inserting new rows into a MySQL table with an auto-incrementing ID column requires obtaining the next available ID value. Here's how to achieve this:
Using the Information Schema:
For the following query to return accurate results, you must ensure that information_schema_stats_expiry is set to 0 (only required once per session):
SET information_schema_stats_expiry = 0; SELECT AUTO_INCREMENT FROM information_schema.tables WHERE table_name = 'table_name' AND table_schema = DATABASE( );
Using `SHOW TABLE STATUS:
This query returns the next auto-increment ID value along with additional table information:
SHOW TABLE STATUS LIKE 'table_name';
Once you have the next available ID value, you can insert a new row into the payments table using the following query:
INSERT INTO payments (date, item, method, payment_code) VALUES (NOW(), '1 Month', 'paypal', CONCAT("sahf4d2fdd45", id))
The above is the detailed content of How to Get the Next Auto-Increment ID in MySQL?. For more information, please follow other related articles on the PHP Chinese website!

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.
