How to insert a SQLite record with a datetime set to 'now' in Android application?

Solution 1:

You cannot use the datetime function using the Java wrapper "ContentValues". Either you can use :

  • SQLiteDatabase.execSQL so you can enter a raw SQL query.

    mDb.execSQL("INSERT INTO "+DATABASE_TABLE+" VALUES (null, datetime()) ");
    
  • Or the java date time capabilities :

    // set the format to sql date time
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss"); 
    Date date = new Date();
    ContentValues initialValues = new ContentValues(); 
    initialValues.put("date_created", dateFormat.format(date));
    long rowId = mDb.insert(DATABASE_TABLE, null, initialValues);
    

Solution 2:

In my code I use DATETIME DEFAULT CURRENT_TIMESTAMP as the type and constraint of the column.

In your case your table definition would be

create table notes (
  _id integer primary key autoincrement, 
  created_date date default CURRENT_DATE
)

Solution 3:

Method 1

CURRENT_TIME – Inserts only time
CURRENT_DATE – Inserts only date
CURRENT_TIMESTAMP – Inserts both time and date

CREATE TABLE users(
    id INTEGER PRIMARY KEY,
    username TEXT,
    created_at DATETIME DEFAULT CURRENT_TIMESTAMP
);

Method 2

db.execSQL("INSERT INTO users(username, created_at) 
            VALUES('ravitamada', 'datetime()'");

Method 3 Using java Date functions

private String getDateTime() {
        SimpleDateFormat dateFormat = new SimpleDateFormat(
                "yyyy-MM-dd HH:mm:ss", Locale.getDefault());
        Date date = new Date();
        return dateFormat.format(date);
}

ContentValues values = new ContentValues();
values.put('username', 'ravitamada');
values.put('created_at', getDateTime());
// insert the row
long id = db.insert('users', null, values);

Solution 4:

There are a couple options you can use:

  1. You could try using the string "(DATETIME('now'))" instead.
  2. Insert the datetime yourself, ie with System.currentTimeMillis()
  3. When creating the SQLite table, specify a default value for the created_date column as the current date time.
  4. Use SQLiteDatabase.execSQL to insert directly.

Solution 5:

To me, the problem looks like you're sending "datetime('now')" as a string, rather than a value.

My thought is to find a way to grab the current date/time and send it to your database as a date/time value, or find a way to use SQLite's built-in (DATETIME('NOW')) parameter
