Mysql
如何在 MySQL 中獲取下一個自增 id?
如何在 mysql 中獲取下一個 id 以將其插入表中?
INSERT INTO payments (date, item, method, payment_code) VALUES (NOW(), '1 Month', 'paypal', CONCAT("chaminda", id))
這是一種方法。
Step 1: Insert without payment_code. Step 2: Get mysql_insert_id from STEP 1. Step 3: Update payment_code with where condition as mysql_insert_id.
PHP 中的程式碼片段: 可能需要更正命令。
1. mysql_query("INSERT INTO payments (date, item, method, payment_code) VALUES (NOW(), '1 Month', 'paypal')"); 2. printf("Last inserted record has id %d\n", mysql_insert_id()); 3. mysql_query(“UPDATE payments set payment_code=CONCAT("chaminda",mysql_insert_id()) where id=mysql_insert_id());
