Article Introduction：Introduction to the analysis of the implementation principle of MySQL lock: In the environment of concurrent access to the database, in order to ensure the integrity and consistency of the data, the database system needs to implement a lock mechanism. The lock mechanism ensures that different transactions can access and modify data in an orderly manner by restricting access to shared resources. As a commonly used relational database, MySQL also provides a variety of lock mechanisms to deal with concurrent access issues. This article will analyze the implementation principles of MySQL locks and provide specific code examples. Classification of MySQL locks in MySQL

Article Introduction：MySQL database automatic submission mechanism analysis MySQL is a commonly used open source relational database management system. It uses a method called an automatic submission mechanism to process transactions. In MySQL, the automatic submission mechanism is turned on by default, which means that each SQL statement will be executed immediately and submitted to the database, causing irreversible effects. Understanding MySQL's automatic commit mechanism is very important for developers because it directly affects transaction control and data integrity. automatic submission mechanism

Article Introduction：What are the mechanisms of the songtide resonance circuit? The Tide Resonance Loop mechanism is a special skill mechanism, because this mechanism can improve one's combat capabilities. Many friends still don’t know what the mechanisms of the Ming Tide Resonance Loop are. The following is an analysis of the Ming Tide Resonance Loop mechanism. Let’s take a look at it together. What are the mechanisms of the Sing Tide Resonance Circuit? Each resonator has its own unique resonance circuit. Proper use of this mechanism can effectively improve combat capabilities. The release mechanism of special skills can be viewed in "Resonance Loop". Taking Kakaro as an example: Release normal attacks/skills to hit the enemy to obtain [Killing Intent] (which can be understood as special skill charging). The resonance loop (special skill) is fully charged. /Not full diagram:

Article Introduction：What about the energy mechanism of Ming Tide Concerto? The energy mechanism of Singing Tide Concerto is a special skill mechanism with exit skills. Many friends still don’t know what the energy mechanism of the Ming Tide Concerto is. Here is an analysis of the energy mechanism of the Ming Tide Concerto. Let’s take a look at it together. How about the sounding tide concert energy mechanism? By releasing skills, causing damage to enemies, triggering extreme dodge, etc., the resonance energy of the resonance can be accumulated. When the on-site resonator's concert energy is full, switching resonators will trigger a special effect: the leaving resonator will trigger its own sustain skill (which can be understood as an exit skill) and clear its own concert energy. The entering resonator will trigger its own Variation skills (can be understood as entry skills). Variation skills can greatly reduce the resonance of enemies. Each character has independent sustain skills and variation skills.
