Using transactions

SQLite statements always run in transactions. If the statement runs successfully, the transaction is automatically committed. If the statement fails, the transaction is rolled back.

By default, a separate transaction is created for each SQLite statement, which is less efficient than running multiple statements in one transaction. You can usually improve performance by explicitly specifying transactions for groups of statements. You can run multiple statements in one transaction using Database.beginTransaction() and Database.commitTransaction() around groups of statements.

Nested transactions are not supported.
