Visible/accessible in LO - OK! Created Foreign Key using DB Browser and tested with the two tables - got FOREIGN KEY constraint failed when appropriate - OK, foreign keys can be set. Next, again using DB Browser set up two tables with data. CREATE TABLE IF NOT EXISTS families ( id INTEGER PRIMARY KEY, reference VARCHAR (32) NOT NULL, name TEXT NOT NULL, unite VARCHAR) We then create a table of articles. So we first create the SQLite table for families. Still no luck in LO but now the setting was on (couldn’t seem to change the setting in originally created DB). To express this relationship we need to add a Foreign key to families inside the articles table. After many pages, I remembered seeing (can’t locate it again) where Foreign Keys setting needed to be set when CREATING the DB. during an auto-migration foreign key constraint check. The tool I found most useful was DB Browser for SQLite (Synaptic Package Manager - sqlitebrowser). SQLite provides referential integrity constraints that we call as foreign keys. The Room persistence library provides an abstraction layer over SQLite to allow for more robust. Quite a bit of net searching and trial and error (even went so far as to completely compile SQLite) led me to these results. Except for testing (and maybe portability) not worth it in my book. ![]() ![]() Worst to get working without a doubt (have HSQLDB server, MySQL server, and PostgreSQL server). Enabling Foreign Key Support " in the post.Ĭould not help much without the actual software so decided to install. It seems it may be off as a default and may need to be turned on. One can go about using SQLite via a GUI, such as DB Browser, or by executing a series of statements in the command line. When editing a cell with a foreign-key, show a list of possible values in a dropdown list (614, 1550). I don’t have any experience with SQLite but found this post ( click here) and a few others like it referring to Enable Foreign Key Support.
