Retrieving the last insert id from MySql using PHP

Question

I have two tables in MySql database, one is sales_order and the other is sales_order_details which contains the details of the order in the s

Answer 1

There are 2 ways which you could solve this:

After inserting the entry in the sales_order:

1. Get the last_insert_id and store it in a php variable, then inject this value into the relevant queries.

2. Store the last_insert_id in a MySql user-defined variable and use the variable in the query instead of last_insert_id.

sample code for option 2

SET @last_order_id = last_insert_id();

insert into sales_order_details (order_id, prod_id, prod_price)
values (@last_order_id, 5, 1500);`

insert into sales_invoice (order_id, invoice_id)
values (@last_order_id, 1);`
