更新查询的MYSQL死锁错误

Question

我目前正在将数据库从MSSQL更改为MYSQL，并且遇到一个包含OUTPUT INSERTED的查询的问题。*

我尝试为MYSQL进行尽可能准确的转换，但是查询出现死锁错误。

任何人都可以告诉我我要去哪里哪里或应该如何处理这种情况。

MSSQL查询：

UPDATE TestSessionScenarios
SET AssignedAt = GETUTCDATE()
OUTPUT INSERTED.*
WHERE Id = (SELECT TOP 1 t1.Id
FROM TestSessionScenarios t1 WITH (UPDLOCK, HOLDLOCK)
WHERE t1.TestSessionId = {0}
AND t1.AssignedAt IS NULL
ORDER BY t1.FailureCount ASC)

MYSQL转换：

START TRANSACTION;
SET SESSION TRANSACTION ISOLATION LEVEL READ UNCOMMITTED ; 
UPDATE TestSessionScenarios
SET AssignedAt = NOW(), Id = LAST_INSERT_ID(Id)
WHERE Id = (SELECT * FROM (
SELECT t1.Id
FROM TestSessionScenarios t1
WHERE t1.TestSessionId = {0}
AND t1.AssignedAt IS NULL
ORDER BY t1.FailureCount ASC
LIMIT 1) as temp);
SELECT * from TestSessionScenarios WHERE Id = LAST_INSERT_ID();
COMMIT;

预先感谢您：）
