Bug 13984: Add atomic update - Insert pref CardnumberLength if not

In modern SQL DBMSs atomicity isn't really an issue. BEGIN ATOMIC is part of the ANSI SQL standard. SQL Server SQL Server unterstützt ATOMIC-Blöcke auf der obersten Ebene der nativ kompilierten gespeicherten Prozeduren sowie für nativ kompilierte, skalare benutzerdefinierte Funktionen. supports atomic blocks at the top-level of natively compiled stored procedures, as well as for natively compiled, scalar user-defined functions. If multiple columns are specified for a COMMENT or LABEL statement, the columns are processed one at a time, so the entire SQL statement is not atomic, but the COMMENT or LABEL to each individual column or object will be atomic.

In SQL databases transaction atomicity is implemented most frequently using write-ahead logging (meaning that the transaction log entries are written before the actual tables and indexes are updated). Queries in the strict sense of the word, that is, SELECT statements and other read operations that do not change the database state, are not logged At present, in SQL Server it is only available for natively compiled stored procedures. 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. In a transaction involving two or more discrete pieces of information, either all of the pieces are committed or none are.

At one moment in 2017-06-27 · SQL supports atomic increment and decrement operations on numeric columns. The “trick” is to use an update query based on the following pattern: -- This assumes the existence of a table defined as: -- CREATE TABLE test(id SERIAL PRIMARY KEY, x INTEGER); UPDATE test set x = x - 1 where id = 1; "Atomic" means "cannot be divided or split in smaller parts".
