How do I make an UPDATE while joining tables on SQLite?
You can't. SQLite doesn't support JOINs in UPDATE statements.
But, you can probably do this with a subquery instead:
UPDATE closure SET checked = 0 WHERE item_id IN (SELECT id FROM item WHERE ancestor_id = 1);Or something like that; it's not clear exactly what your schema is.
You can also use REPLACE then you can use selection with joins.Like this:
REPLACE INTO clusure SELECT sel.col1,sel.col2,....,sel.checked --checked should correspond to column that you want to changeFROM ( SELECT *,0 as checked FROM closure LEFT JOIN item ON (item_id = id) WHERE ancestor_id = 1) sel
