Limitations

Turso Cloud is compatible with most SQLite features, but there are some known limitations to be aware of — especially if you’re migrating from vanilla SQLite.

​
Pragma statements

Some SQLite pragma statements behave differently on Turso Cloud or are not supported.
PragmaNotes
user_versionRead-only on Turso Cloud. Use a _schema_version table instead to track schema migrations.
application_idRead-only on Turso Cloud. Use a _metadata table instead to store application identifiers.
busy_timeoutNot supported. Turso Cloud manages concurrency internally, so setting a busy timeout has no effect.
journal_modeNot supported. Turso Cloud manages journaling internally and does not allow changing the journal mode.
If you’re using PRAGMA user_version to track schema migrations (common in vanilla SQLite), you’ll need to switch to a table-based approach on Turso Cloud:
CREATE TABLE IF NOT EXISTS _schema_version (version INTEGER NOT NULL);
INSERT INTO _schema_version (version) VALUES (0);
