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.
Enter the super-journal: a top-level journal file that spans all affected databases, ensuring a multi-file commit remains atomic. For multiple virtual tables within the same database file, however, the standard rollback journal suffices; no super-journal is required. In all cases—whether multiple vtables in one file or across attached databases—virtual-table hooks ( xSync, xCommit, xRollback) are invoked as part of SQLite’s transaction process.
