sqlcode=-1477 sqlstate=55019

This error code indicates that the operation being performed has been cancelled due to a deadlock situation. A deadlock occurs when two or more transactions are waiting for each other's resources to be released, causing a circular dependency that cannot be resolved. To resolve this issue, you can try to modify the transaction isolation level, optimize the SQL queries, or introduce timeouts to prevent long-running transactions. Alternatively, you can manually terminate one of the transactions involved in the deadlock to release the resources and allow the other transaction to proceed.
