MySQL Error number: 3022; Symbol: ER_WARN_OPEN_TEMP_TABLES_MUST_BE_ZERO; SQLSTATE: HY000

文档解释

Error number: 3022; Symbol: ER_WARN_OPEN_TEMP_TABLES_MUST_BE_ZERO; SQLSTATE: HY000

Message: This operation may not be safe when the replica has temporary tables. The tables will be kept open until the server restarts or until the tables are deleted by any replicated DROP statement. Suggest to wait until replica_open_temp_tables = 0.

Error number: 3022; Symbol: ER_WARN_OPEN_TEMP_TABLES_MUST_BE_ZERO; SQLSTATE: HY000

错误说明:

ER_WARN_OPEN_TEMP_TABLES_MUST_BE_ZERO错误表明MySQL引擎在提交事务之前,发现打开的临时表大于0,但是实际上必须为0. 该错误属于严重错误级别,会导致提交失败.

常见案例:

当MySQL中打开的临时表数量超过MySQL引擎允许打开的表时,会出现此错误,也可能是临时表未关闭或中途死机导致数据不一致。

解决方法:

1. 检查脚本中是否有未正确关闭临时表的情况

2. 必要时重启MySQL服务器,清除错误的旧会话

3. 检查MySQL参数是否正确设置,如open_temp_tables参数
