In fact, the real standard struct

Tags: read feature prevents read lock generation MYSQ deadlock NoteLocking is used to ensure transactional integrity and database consistency. Locking prevents users from reading data that other users are changing and prevents multiple users from changing the same data at the same time. Without locking, the data in the database can become logically incorrect, and querying for that data can produce unexpected results.In computer science, a lock is a synchronization mechanism used to forcibly rest

worse than one (satisfying the advanced lock must satisfy the low-level lock). But there is a very deadly place where a first-class lock protocol is to be read with an X lock until the end of the transaction. Almost the entire transaction is written and locked, very inefficient. Level three blocking protocol is only a theoretical thing, and the actual database often uses another method to solve the transaction concurrency problem.Ii. level of isolationMySQL uses intent locks (another mechanism)

Abstract: loading data for a database is one of the important responsibilities of the Administrator. It is precisely because of the importance that MySQL provides a wide range of methods. The INSERT and LOAD statements are mainly used. INSERT new data using the INSERT statement Syntax: INSERT [INTO] tbl_name [(col_name,...)] VALUES (pression ,...),...INSERT [INTO] tbl_name SET col_name = expression ,... Let's start to use the INSERT statement to add records. This is an SQL statement. You need to

Oracle row-level locks and table-level locks. If the row record has been locked, wait for 5 seconds for updates. If the row record is unlocked within these 5 seconds, the query result is returned, if 5 seconds Oracle row-level locks and
