数据截断:错误的日期时间值:“
谁能通过示例JSP代码帮助我,以通过JDBC在MySql数据库中存储日期?当我尝试执行下面给出的代码时,出现以下异常:
com.mysql.jdbc.MysqlDataTruncation:数据截断:不正确的datetime值:第1行的’date’列的’‘
如何克服这个问题?以下是我的代码:
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);
}
回答:
要将日期设置为准备好的语句,您需要更改值的类型:
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());
现在将String date转换为java.sql.Date并使用另一种方法:
preparedStatement.setDate(4,dateDB);
