Dear list, Is there a way to make SQLite accept this kind of constraint:
CREATE TABLE tab ( id INTEGER NOT NULL, data INTEGER, CHECK(data = 0 or not exists (select 1 from tab where id = data))); This toy exemple doesn't mean much as it is and the actual situation is a bit more involved. Anyway, the crux of it is that the table name doesn't yet exist when the parser looks at the constraint, hence SQLite issues a "no such table: tab" error. The docs say that a check table constraint can be any expression but this is clearly not the complete picture. I tend to think that this statement should be accepted, but I'm in no way an expert in ISO SQL. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
