here is my application scenario: assuming there is a table in mysql, named orders including 4 fields(id, orderid, money, type), everytime I pick the last item of each orderid to manipulate. For examle, i choose one order whose orderid=777, i.e. this item (3, 777, 34.00, 1), to consume $2.00. Then this item firstly is changed into (3, 777, 34.00, 0), and then I insert one row into the table (4, 777, 32.00, 1).


But with the concurrency, there are probably two sessions to select the item(3, 777, 34.00, 1) at the same time, then consume $2.00 based on the same item. Now I totally have items (3, 777, 34.00, 0), (4, 777, 32.00, 1), (5, 777, 32.00, 1). Normally, everytime it should consume money based on the very last item of the order, i.e., (3, 777, 34.00, 0), (4, 777, 32.00, 0), (5, 777, 30.00, 1)


last = getInfoByOrderId(orderid, type);
//...
// if last does not satisfy some conditon, then return or throw exceptions directly
//...
