Unfortunately, due to a bug in some early versions, this is not the case in SQLite. Unless the column is an [INTEGER PRIMARY KEY](https://www.sqlite.org/lang_createtable.html#rowid) or the table is a [WITHOUT ROWID](https://www.sqlite.org/withoutrowid.html) table or a [STRICT](https://www.sqlite.org/stricttables.html) table or the column is declared NOT NULL, SQLite allows NULL values in a PRIMARY KEY column. SQLite could be fixed to conform to the standard, but doing so might break legacy applications. Hence, it has been decided to merely document the fact that SQLite allows NULLs in most PRIMARY KEY columns. | {"total_count": 0, "+1": 0, "-1": 0, "laugh": 0, "hooray": 0, "confused": 0, "heart": 0, "rocket": 0, "eyes": 0} | 1857234285 |
