How do I select and count records less than 1 year old?

Question

I'm using sqflite in my Flutter application. In this example, date is the actual date(10.06.2021) and DATUM is the datafield in the DB.

var x = await db.rawQuery('SELECT COUNT (*) FROM Shisha_table WHERE YEAR('+date+') - YEAR(DATUM) = 1');
int count = Sqflite.firstIntValue(x);
return count;

I keep getting this syntax error:

E/SQLiteLog(30657): (1) near ".2021": syntax error in "SELECT COUNT (*) FROM Shisha_table WHERE (YEAR(10.06.2021) - YEAR(DATUM)) = 1"

Answer 1

There is no YEAR() function in SQLite.

The logic of your code can be written by extracting the year of a date with the use of the function strftime() :

SELECT COUNT(*) 
FROM Shisha_table 
WHERE strftime('%Y', CURRENT_DATE) - strftime('%Y', DATUM) <= 1

Or, if you want the rows from the same date in last year untill today:

SELECT COUNT(*) 
FROM Shisha_table 
WHERE DATUM >= date(CURRENT_DATE, '-1 year')
