Question

I have difficulties comparing the date from my android os to a date stored in my sqlite database on the phone. The goal is: I would like to select all rows for a date earlier than today.

That’s how I get the Date – that park works:

  android.text.format.DateFormat df = new android.text.format.DateFormat();
  String datum = df.format("yyyy-MM-dd", new java.util.Date()).toString ();

For each row in my database I have stored the date as TEXT. e.g. 2012-01-31 (yyyy-MM-dd).

I thought, I could work with “smaller than” ( < ) operator – that worked on a differt project. But, I don’t get the correct dates.

Any ideas? Or – how would you approach that problem?

Thanks in advance!

Answer 1

Works fine for me.

$ sqlite3
sqlite> CREATE TABLE date_test(date DATE);
sqlite> INSERT INTO date_test VALUES('2012-01-01');
sqlite> INSERT INTO date_test VALUES('2012-02-01');
sqlite> INSERT INTO date_test VALUES('2012-03-01');
sqlite> SELECT date FROM date_test WHERE date < '2012-02-15';
2012-01-01
2012-02-01

Can you provide specific test data for which the behavior is not what you expect?
