如何使用jsp在mysql数据库中插入当前日期？

Question

I am trying to insert the date using this code:

java.sql.Timestamp sqlNow=new java.sql.Timestamp(new java.util.Date().getTime());
pstTimestamp(1,sqlNow);

On running the code, the result is successful, but the date is not been displayed in the database.

Answer 1

You should use PreparedStatement and use it to set the date as follows :-

PreparedStatement pstmt = con.prepareStatement("INSERT INTO table_name (col_name) VALUES (?)");
pstmt.setTimestamp(1, new java.sql.Timestamp(new java.util.Date().getTime()));
pstmt.executeUpdate();

Answer 2

Try this

PreparedStatement ps = con.prepareStatement("INSERT INTO table_name (col_name) VALUES (now())");
ps.executeUpdate();

use now() so that it will get the date in db format only.

Answer 3

Make sure you commit after running the command. Or make sure auto commit is enabled on the connection.

Answer 4

Just you need to provide the java.sql.Timestamp class object to the PreparedStatement object rest of work will be done by driver. I think there is a problem in your code while setting place holder's value(parameter). Use pstmnt.setTimestamp(int index, java.sql.Timestamp timestamp_object); now execute your query as: pstmnt.executeUpdate();
