![]() COMMIT Code language: SQL (Structured Query Language) ( sql ) Third, commit the changes to the database by using the COMMIT or COMMIT TRANSACTION statement. Note that the change is only visible to the current session (or client). Second, issue SQL statements to select or update data in the database. BEGIN TRANSACTION Code language: SQL (Structured Query Language) ( sql )Īfter executing the statement BEGIN TRANSACTION, the transaction is open until it is explicitly committed or rolled back. To start a transaction explicitly, you use the following steps:įirst, open a transaction by issuing the BEGIN TRANSACTION command. It means that for each command, SQLite starts, processes, and commits the transaction automatically. On the contrary, if the program crashes before the transaction is committed, the change should not persist.īy default, SQLite operates in auto-commit mode. Durable: if a transaction is successfully committed, the changes must be permanent in the database regardless of the condition such as power failure or program crash.On the other hand, the changes committed by other sessions after the transaction started should not be visible to the current session. When a session starts a transaction and executes the INSERT or UPDATE statement to change the data, these changes are only visible to the current session, not others. Isolation: a pending transaction performed by a session must be isolated from other sessions.However, when the transaction is committed or rolled back, it is important that the transaction must keep the database consistent. When a transaction starts and executes a statement to modify data, the database becomes inconsistent. Consistent: a transaction must ensure to change the database from one valid state to another.When you commit a transaction, either the entire transaction is applied or not. It means that a change cannot be broken down into smaller ones. Atomic: a transaction should be atomic.SQLite guarantees all the transactions are ACID compliant even if the transaction is interrupted by a program crash, operation system dump, or power failure to the computer. SQLite is a transactional database that all changes and queries are atomic, consistent, isolated, and durable (ACID). ![]() ![]() Suppose we have a database table that stores information about customers, and we want to add a new customer.Summary: in this tutorial, we will show you how to use the SQLite transaction to ensure the integrity and reliability of the data. It can be useful when you need to make sure that multiple operations are all successful, or if you want to be able to undo all the operations as a group. Finally, you call IDbTransaction.Commit() or IDbTransaction.Rollback() to complete the transaction.ĭapper support the transaction and TransactionScope Transactionīegin a new transaction from the connection and pass it in the transaction optional parameter.Then, you execute all the operations that you want to be part of the transaction using this IDbConnection object.Next, you call IDbConnection.BeginTransaction() to start a new transaction.First, you create an IDbConnection object, which represents a connection to your database.Using Dapper's transaction support is very simple. Transactions allow you to group multiple operations into a single unit of work, which can then be committed or rolled back as a single unit. One of the key features of Dapper is its support for managing transactions. Bulk Merge Dapper Transaction Discover How to Manage your Transaction Description ![]()
