Add a new dropdown box to the Import CSV dialog to set an ON CONFLICT
strategy when importing into an existing table. You can now choose
between the old and still default behaviour of aborting the import in
case of a conflict, ignoring the conflicting row from the CSV file, and
replacing the existing row in the table.
See issue #1585.
Because there are some circumstances under which the automatic type
detection can cause problems with the imported data and because it is
not accurate when the data changes a lot after the first couple of rows,
we need an option to disable it.
See issue #1382.
This changes the default behaviour for the CSV import to follow a set of
rules which hopefully makes most people happy.
It also add an "Advanced" section to the settings bits of the dialog to
modify this new default behaviour.
See issue #1395.
* Add a combo box for missing values in import ui
* Add ui pieces to .cpp file
* Insert NULL values if requested
* Allow inserting NULLs in new table also
- Tweak input checker
- Preserve old file import as not to cause any unforeseen breaks
- Allow ignoring file name when importing multiple files to tables
- Mass toggle several files for import
Make it possible to use other quote and separator characters than those
predefined in the respective combo boxes when importing a CSV file.
See issue #23.
Rewrite the dialog to import CSV files using a Qt Creator form file.
Simplify the CSV import a little bit.
A bit unrelated, but needed for this anyway:
Create the restorepoint right after opening a database file instead of
just doing so after the first change.
