In SQLite, a transaction is a sequence of database operations that are treated as a single unit of work. Transactions are used to ensure data integrity and consistency, and to prevent data loss or corruption in case of errors or failures.
When you begin a transaction in SQLite, you use the BEGIN TRANSACTION statement. This statement marks the beginning of the transaction and sets a transaction savepoint. Once the transaction has started, you can perform any number of database operations, such as inserting, updating, or deleting records.
Once you have completed all the required database operations, you must end the transaction. To do this, you can use the END TRANSACTION statement. This statement marks the end of the transaction and commits all the changes made during the transaction to the database.
Syntax
The syntax of the END TRANSACTION statement is as follows:
END TRANSACTION;
Alternatively, you can use the COMMIT statement to end the transaction and commit the changes to the database. The syntax of the COMMIT statement is as follows:
COMMIT;
If you want to cancel the transaction and discard any changes made during the transaction, you can use the ROLLBACK statement. The syntax of the ROLLBACK statement is as follows:
ROLLBACK;
It’s worth noting that SQLite transactions are atomic, which means that either all the changes made during the transaction are committed to the database, or none of them are. This ensures that the database remains in a consistent state, even in the case of errors or failures.
In summary, the END TRANSACTION statement is used to mark the end of a transaction in SQLite and commit any changes made during the transaction to the database.
