Just in case also make sure the zeroblob function is working: ``` sqlite> select length(zeroblob(1228)); ┌────────────────────────┐ │ length(zeroblob(1228)) │ ├────────────────────────┤ │ 1228 │ └────────────────────────┘ ``` ie, when called as above the result value should be the same as the argument given.
