SQLSTATE[40001]: Serialization failure: 1213 Deadlock found when trying to get lock; try restarting transaction

SQLSTATE [40001]: Serialization failure with error code 1213 typically indicates a deadlock issue in your database transaction. A deadlock occurs when two or more transactions are waiting for each other to release resources that the other needs, resulting in both transactions being blocked indefinitely.

Here's what this message means:
1. **Deadlock**: Two or more processes (transactions) have互相等待对方释放锁，形成了一种循环依赖，导致它们都无法继续执行。
2. **Trying to get lock**: The database engine is attempting to acquire a lock on data that is currently locked by another transaction, but the lock can't be immediately obtained.
3. **Restarting transaction**: To resolve the deadlock, you usually need to terminate and restart one of the conflicting transactions. Some databases might allow automatic deadlocks detection and resolution, while others require manual intervention.

To prevent deadlocks, it's good practice to minimize transaction duration, use optimistic locking whenever possible, and avoid locking large sets of rows at once. Additionally, monitoring and optimizing your database configuration can help reduce the likelihood of these issues occurring.
