transaction

Transaction is to ensure the atomicity, consistency, isolation, and permanence of logical processing.With transaction control, you can avoid a series of problems, such as dirty data, caused by the failure of logical processing.Transactions have two

Transaction definitionTransaction management is essential for enterprise applications, and the primary role is to ensure data consistency, such as transfer issues. The following pseudo-code shows:Transaction begin A account buckle B account

Transactions are the guarantee of the atomicity of logic, and by using transaction control, it is possible to avoid problems such as dirty data caused by logical processing failure.The two most important features of a transaction are the level of

We know that in a relational database there are four properties for a transaction: atomicity (atomicity): a transaction is executed as a whole, and the operations contained therein are either completely executed or not executed.

BEGIN TRANSACTIONMarks the starting point for an explicit local transaction. BEGIN TRANSACTION The @ @TRANCOUNT by 1 increments.BEGIN TRANSACTION represents a point where data referenced by a connection is logically and physically consistent at that

ACID, refers to the four characteristics of a transaction in a database management system (DBMS): atomicity (atomicity), consistency (consistency), isolation (isolation, also known as independence), persistence (durability). In a database system, a

Data | database What is a database transaction A database transaction is a series of actions performed as a single logical unit of work. The payment process includes at least the following database operations, assuming a single transaction for

In real business scenarios, we often encounter problems with frequent data modification reads. At the same time, different business logic modifies the same table data, which is likely to cause data irreparable confusion, so we need to manage the
