sql = “INSERT INTO mytable (datetime) VALUES (‘$datetime’)”;另一个解决方案是使用存储带有毫秒级时间精度的时间戳的其他数据库，例如PostgreSQL和Oracle。这些数据库支持不同的时间类型，例如TIMESTAMP WITH TIME ZONE，它们可以存储具有毫秒级精度的时间戳。需要指出的是...
datetime 以”YYYY-MM-DDHH:MM:SS”格式检索和显示datetime值。支持的范围为”1000-01-01 00:00:00″到”9999-12-31 23:59:59″ TIMESTAMP值不能早于1970或晚于2037 TIMESTAMP 1、4个字节储存(Time stamp value is stored in 4 bytes) 2、值以UTC格式保存( it stores the number of milliseconds) ...
datetime 以'YYYY-MM-DD HH:MM:SS'格式检索和显示DATETIME值。支持的范围为'1000-01-01 00:00:00'到'9999-12-31 23:59:59'TIMESTAMP值不能早于1970或晚于2037 储存 TIMESTAMP 1.4个字节储存(Time stamp value is stored in 4 bytes) 2.值以UTC格式保存( it stores the number of milliseconds) ...
datetime包含毫秒，要格式化输出，用fffDateTime t = DateTime.Now;Console.WriteLine(t.ToString("yyyy-MM-dd hh:mm:ss fff"));注：mysql里面的datetime类型的精确度是可以到1/ 10 ^ 6 秒的，某些客户端（如navicat for mysql）的显示经常只能看到精确到秒，其实是设计表的时候的配置问题。
If set to a non-zero value, the driver will close the connection and report failure when 'com.mysql.cj.jdbc.JdbcConnection.ping()' or 'java.sql.Connection.isValid(int)' is called if the connection's lifetime exceeds this value, specified in milliseconds. ...
When retrieving, the conversion is performed only if the source column has the TIMESTAMP, DATETIME or character type and the target class is an instant-based one, like 'java.sql.Timestamp' or 'java.time.OffsetDateTime'. Note that this option has no effect if used in conjunction with "...
