ContentValues put method

问题

At the db side, checkInTime and checkOutTime are of type TIMESTAMP

In my java code also, checkInTime and checkOutTime are of type java.sql.Timestamp

For inserting a record into db, i am using this piece of code:

1. ContentValues contentValues=new ContentValues();

    2. contentValues.put(USER_ID, userId);
    3. contentValues.put(ROOM_ID, roomId);
    4. contentValues.put(CHECK_IN, checkInTime);
    5. contentValues.put(CHECK_OUT, checkOutTime);

    6. return database.insert(MRM_BOOKING_DETAILS_TABLE, null, contentValues);

But i am getting compilation errors at line 4 and 5 since they are not expecting something of type java.sql.Timestamp

I can't see any put method of ContentValues which will accept type java.sql.Timestamp in its second parameter. Please suggest how to pass the java.sql.Timestamp in such a case so that i can remove the compilation errors as well.

Thanks,

I would suggest you to use DATETIME instead of TIMESTAMP. Its more general when handling dates and times.

Moreover, you can use SimpleDateFormat to parse DATETIME values when inserting or reading from database.

final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");

Updated:

Try doing it as below:

final SimpleDateFormat parser = new SimpleDateFormat("yyyy-MM-ddTHH:mm:ss.SSS");

contentValues.put(CHECK_IN, parser.format(checkInTime));
contentValues.put(CHECK_OUT, parser.format(checkOutTime));

If checkInTime and checkOutTime are bith time stamps then before storing thm to contentvalue just convert to milliseconds and store them and while retriving reconvert then them to your required format. because ContentValue dont accept timeStamps so just convert and store so that you wont get any compliation error.
