2. 使用 SQL 查询获取 CURRENT_TIMESTAMP 连接数据库后,我们可以通过 SQL 查询来获取CURRENT_TIMESTAMP。以下是执行查询的示例代码: importjava.sql.Connection;importjava.sql.PreparedStatement;importjava.sql.ResultSet;importjava.sql.SQLException;publicclassGetCurrentTimestamp{publicstaticvoidmain(String[]args){Con...

整理一: String --> Timestamp: Timestamp转换为String可以直接.toString(),但有时候显示时是不需要小数位后面的毫秒值,需要借助DateFormat在转换为String时重新定义格式。 使用Timestamp的valueOf()方法, Timestamp time=newTimestamp(System.currentTimeMillis());//获取系统当前时间SimpleDateFormat df =newSimple...
