[PyQt] to display cotent of database between two dates

[Denni]

Okay you are missing the issue. You are wrapping your variables (and now functions as well) inside your Quotes which turns that entire thing into a single string and that is not what you are wanting to do as string is a string not a variable nor a function. Now if you insist on doing this all in one line (a bad thing to do btw) then change the following:

c=curseur.execute("SELECT * FROM correction_loc35R WHERE date_correction BETWEEN start_date.strftime('%Y-%m-%d') AND end_date.strftime('%Y-%m-%d') ")

To This

c=curseur.execute("SELECT * FROM correction_loc35R WHERE date_correction BETWEEN "+start_date.strftime('%Y-%m-%d')+" AND "+end_date.strftime('%Y-%m-%d'))
