Can anyone help me with a sample JSP code to store date in a MySql database through JDBC? When I try to execute the code given below, I get the following exception:
com.mysql.jdbc.MysqlDataTruncation: Data truncation: Incorrect datetime value: '' for column 'date' at row 1
How to overcome this problem? Following is my code:
Connection con = null;
String StaffName = request.getParameter("StaffName");
// String subcode = request.getParameter("subcode");
String hourId = request.getParameter("hourId");
if (hourId == null)
hourId = "";
String day = request.getParameter("day");
if (day == null)
day = "";
String date = request.getParameter("date");
try {
Class.forName("com.mysql.jdbc.Driver");
con = DriverManager.getConnection("jdbc:mysql://localhost:3306/StaffAllocation", "root", "success");
// PreparedStatement stat = con.PrepareStatement();
String updateString = "INSERT INTO tblstaffallocation (StaffName,hourId,daysId,date) VALUES (?,?,?,?)";
PreparedStatement preparedStatement = con.prepareStatement(updateString);
preparedStatement.setString(1, StaffName);
preparedStatement.setInt(2, 0);
preparedStatement.setInt(3, 0);
preparedStatement.setString(4, date);
} catch (Exception e) {
out.print(e);
}
To set date to prepared statement you need change type of value:
String date = request.getParameter("date");
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd"); // your template here
java.util.Date dateStr = formatter.parse(date);
java.sql.Date dateDB = new java.sql.Date(dateStr.getTime());
now convert String date to java.sql.Date and use another method:
preparedStatement.setDate(4,dateDB);
