在使用MySQL数据库时,如果遇到“data truncation: signed integer value is out of range in 'mysqld_stmt_execut'”这样的错误,通常意味着你尝试插入或更新的数据值超出了字段定义的有符号整数范围。以下是对这个问题的详细分析和解决方法: 1. 错误原因分析 字段类型不匹配:你尝试插入或更新的数据值超出了字段定义...
TIMEThe data is transformed into a TIME data type, which only accounts for the time portion. The format is always in "HH:MM:SS" and can accommodate a range of time between '-838:59:59' and '838:59:59'. CHARIt transforms a given value into a fixed-length string data type called ...

The TIMESTAMP data type has a range of '1970-01-01 00:00:01' UTC to '2038-01-09 03:14:07' UTC. It has varying properties, depending on the MySQL version and the SQL mode the server is running in. 其实DATETIME 和 TIMESTAMP 底层也是整型存储(否则就不会按照 2 的31 次方,63 次方来...
