If you wanted to see one way to use a SQLite date/time field with Flutter and Dart, I hope this example has been helpful. Var currentTimeInSecs = Utils.currentTimeInSeconds() The DateTimeTz type therefore behaves like the DateTime type. I still let my SQL INSERT be handled by the database, but my SQL UPDATE code now looks like this: Sqlite does not support saving timezones or offsets. I just tested that function, and it works properly with the date_last_touched database field shown above. Var ms = (new DateTime.now()).millisecondsSinceEpoch / the current time, in “seconds since the epoch” Important Update #2: Handling the “update” processĪs a result of changing my SQL approach, I also had to create some Dart code to calculate the “seconds since the epoch”: Return await db.insert('quotes', row) //the id Therefore, I replaced that INSERT code with this code: Important Update #1: Avoiding SQL-injectionĪs a very important note, I decided not to use raw SQL code as shown above because it creates a potential SQL-injection problem. These are modifiers that are applied to the timestring. It can be one of the following: modifier1, modifier2. modifiern ) Parameters or Arguments timestring A date value. VALUES ('$')īy skipping the id and date_last_touched fields, I let them use their default values, which makes my Dart code and SQL query simpler. The syntax for the datetime function in SQLite is: datetime (timestring, modifier1, modifier2. Try this: sql'SELECT id, message, sender, recipient, date, time, IF (recipient '.SESSION 'user' 'id'. If the ASC or DESC modifier is not provided in the ORDER BY clause, the results will be sorted. Sorting specifications for multiple columns need to be comma separated. WARNING: i don’t use this approach see the following section It sorts the result set in descending order by expression.
