CANCEL statement

Each statement within SurrealDB is run within its own transaction. If a set of changes need to be made together, then groups of statements can be run together as a single transaction, either succeeding as a whole, or failing without leaving any residual data modifications.

The CANCEL TRANSACTION statement can be used to cancel a set of statements within a transaction, reverting or rolling back any data modification made within the transaction as a whole.

Statement syntax

CANCEL [ TRANSACTION ];
