# sqlite/rollback-async Async twin of `sqlite/rollback` — roll back the open transaction off-thread. Returns a Future resolving to `true`. ## Syntax

[sqlite/rollback-async $db]

## Parameters - `$db` — database handle ## Examples

def db [sqlite/open ":memory:"]
[sqlite/exec $db "CREATE TABLE t (id INTEGER)"]
[await [sqlite/begin-async $db]]
[await [sqlite/exec-async $db "INSERT INTO t VALUES (1)"]]
[await [sqlite/rollback-async $db]]        # → true — the row is discarded
[await [sqlite/scalar-async $db "SELECT count(*) FROM t"]]   # → 0

## Returns Future; `[await ...]` yields `true`, the same value as `sqlite/rollback`. `%Err{:message}` resolves when no transaction is active (`cannot rollback - no transaction is active`) or on other SQLite errors; submit-time errors return `%Err` directly. Jobs run FIFO on the handle's executor, preserving begin/exec/rollback order. The first async call switches the handle to async-only, so later sync `sqlite/*` calls on it return `%Err`. ## See Also `sqlite/rollback`, `sqlite/begin-async`, `sqlite/commit-async`
