Question

i have a sqlite database on my android, whith a datetime column, that contains a date with the Format dd.MM.yyyy. It\'s not my Database, I\'m niot able to change the Datefor

Answer 1

Try this query to change the column to the proper format for a text-date (assume table named table and column named date):

update table set date = substr(date, 7) || "-" || substr(date,4,2) 
  || "-" || substr(date, 1,2);

You can also turn this around into a where clause per this answer.
