How Can I Access the Next Auto-Increment ID in MySQL?

Accessing Auto-Increment IDs in MySQL

Inserting data into MySQL tables often involves referencing auto-incrementing ID fields. To obtain the next ID in the sequence, a few methods are available.

Retrieve Auto-Increment Value with Information Schema

To directly obtain the next auto-increment ID, you can use the following query:

SET information_schema_stats_expiry = 0;
SELECT AUTO_INCREMENT
FROM information_schema.tables
WHERE table_name = 'table_name'
AND table_schema = DATABASE( );

Ensure you set the information_schema_stats_expiry to 0 first, as its default value can result in outdated results.

Obtain Auto-Increment Value with SHOW TABLE STATUS

Alternatively, you can use the SHOW TABLE STATUS query:

SHOW TABLE STATUS LIKE 'table_name';

This query returns a row with various table information, including the current auto-increment value in the Auto_increment column.

Applying in an Insert Query

With the obtained auto-increment value, you can insert it into the table using a query like the one provided in the question:

INSERT INTO payments (date, item, method, payment_code)
VALUES (NOW(), '1 Month', 'paypal', CONCAT("sahf4d2fdd45", id))

simply replace id with the auto-increment value you obtained from one of the methods described above.
