SQLite Transactions and Virtual Tables

In my previous post I introduced SQL virtual tables and how to use them in Go—registering modules per connection, defining schemas, and querying external sources as regular tables. Now let’s dive into more advanced virtual-table implementations: those that support writes and full transactional behavior. Writes and Transaction Support in Virtual Tables SQLite’s virtual-table interface isn’t read-only. By implementing xUpdate you can expose writable tables over any data source. But true transactional integrity requires more than just row-level updates—it requires hooks for transaction boundaries: xBegin : Signal the start of a transaction. : Signal the start of a transaction. xSync : Prepare work for a durable commit; failures here abort everything. : Prepare work for a durable commit; failures here abort everything. xCommit : Finalize the transaction (cleanup only). : Finalize the transaction (cleanup only). xRollback : Revert changes if the transaction is aborted.
