MySQL table export with column names and a date column. How can I solve this?
So far I have managed a CSV export with 5 columns, time, customer, employee, service and description. But I'm not sure is this the right code for the time export. while(rs.next()) { sb.append(rs.getDate("date")); sb.append(";"); sb.append(rs.getTime("time")); sb.append(";"); I tried this code to export the date column, but it doesn't work. I hope you can help me. Thank you. BR Olivia https://code.sololearn.com/cAXM4GW7SFTQ/?ref=app

I recommend you to use following statements to retrieve date column,
Date date = resultset.getDate("");
+ 2
while(rs.next()) {
Date date = rs.getDate("datum");
sb.append(date); sb.append(";"); sb.append(rs.getTime("zeit")); sb.append(";"); sb.append(rs.getString("kunde")); sb.append(";"); sb.append(rs.getString("dienstleistung")); sb.append(";"); sb.append(rs.getString("beschreibung")); sb.append(";"); sb.append(rs.getString("mitarbeiter")); sb.append("\r\n"); }
For date class we have to include import java.util.*;

Use drivermanager class to get connection

Please try,
Date date = resultset.getDate("");

Hi akshay harshora, thank you for your help. :)

akshay harshora I tried it at this position:
while(rs.next()) {
Date date = rs.getDate("");
....
but I received an error like: Date cannot be solved to a type. Which Import I have to do? Import 'Date' (sun.util.calendar.BaseCalendar) or (sun.util.calendar.LocalGregorianCalendar) or (java.util) or (java.sql)
