Se hela listan på sqlite.org MySQL 8.0 supports atomic Data Definition Language (DDL) statements. This feature is referred to as atomic DDL . An atomic DDL statement combines the data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single, atomic operation. If multiple tables, SQL packages, or users are specified for a GRANT or REVOKE statement, the tables are processed one at a time, so the entire SQL statement is not atomic, but the GRANT or REVOKE to each individual table will be atomic.

2019-05-28 · SQL Server transaction boundaries help you to identify when a SQL Server transaction starts and ends by using API functions and methodsas in the following: Transact-SQL statements: Use the BEGIN TRANSACTION, COMMIT TRANSACTION, COMMIT WORK, ROLLBACK TRANSACTION, ROLLBACK WORK, and SET IMPLICIT_TRANSACTIONS statements to delineate transactions. SQL Reference; Syntax There are two types of parsers in the system: the full SQL parser (a recursive descent parser), and the data format parser (a fast stream parser). In all cases except the INSERT query, only the full SQL parser is used. The INSERT query uses both parsers: Definition: a transaction is a group of SQL commands whose results will be made visible to the rest of the system as a unit when the transaction commits --- or not at all, if the transaction aborts. Transactions are expected to be atomic, consistent, isolated, and durable.

Distributed SQL databases typically use the Paxos or Raft algorithms to achieve consensus across multiple nodes. Sometimes distributed SQL databases are referred to as NewSQL but NewSQL In this chapter, we will discuss the transactions in PL/SQL. A database transaction is an atomic unit of work that may consist of one or more related SQL statements. It is called atomic because the database modifications brought about by the SQL statements that constitute a transaction can collectively be either committed, i.e., made permanent to the database or rolled back (undone) from the SQL language support in Atom. Adds syntax highlighting to SQL files in Atom.

Key differences with BEGIN TRAN are that ATOMIC blocks either fail or succeed as a whole, and the ATOMIC block takes care of the transaction commit/rollback for you: if the block succeeds, it is committed; if the block fails it rolls back. Atomicity.
