Inserting date into MySQL database using a PreparedStatement

问题

I want to update the string date into MySQL database using prepared statement. I have tried a lot and always got error java.util.Date cannot parse into java.sql.Date or vise versa. I didn't import anything here. Please import according to your answer.

public class Date1 
{ 
    public static void main(String args[]) 
    {
        String source="2008/4/5";              
        SimpleDateFormat format = new SimpleDateFormat("dd/MM/yyyy");                       
        java.sql.Date d=(Date) format.parse(source);             
        Class.forName("com.mysql.jdbc.Driver");        
        Connection con=(Connection) DriverManager.getConnection("jdbc:mysql://localhost:3306/employee", "root", "root");   
        PreparedStatement ps=con.prepareStatement("insert into ankur1 values(?)");          
        ps.setDate(1,(java.sql.Date) d);    
        ps.executUpdate();
    }
}

回答1:

Write this

java.sql.Date d= new java.sql.Date(format.parse(source).getTime());

instead of this:

java.sql.Date d=(Date) format.parse(source);

Because you cannot just cast java.util.Date to its subtype java.sql.Date. You have to convert it. Do also note that your format string doesn't match your actual date format, as Bill the Lizard commented.

回答2:

java.sql.Timestamp date = new java.sql.Timestamp(new java.util.Date().getTime());

pstmt.setTimestamp(1, date);

Try this it may work.. Thanks

here is another simpler way to solve this:

preparedStatement = connect.prepareStatement("INSERT INTO test.TABLENAME VALUES (default, STR_TO_DATE( ?, '%m/%d/%Y'), STR_TO_DATE(?, '%l:%i %p'),?,?,?,?,?)");

Or, you can replace the "?" with real data.

This is how I insert date and time to mySQL, just figured it out.

We can adjust the kinds of parameters to meet our data's format, it's easy and clean.
