# Useful queries
This document contains useful queries that should be performed manually in exceptional situations.

## Remove data for an artifact from the DB
## Remove data for a stable artifact from the DB
This is important for situations where there is some compilation error for a stable benchmark,
with a stable release of the compiler. While this should be rare, it happens sometimes e.g. because
of future incompatibility lints turning into errors.

type = 'release';
```
After executing this query, the server should automatically re-benchmark these artifacts again.

## Remove data for a master/try artifact from the DB
This is similar to removing a stable artifact, however it also has to be removed from the
`pull_request_build` table.

```sql
DELETE FROM artifact
WHERE name = "<sha>";

DELETE FROM pull_request_build
WHERE bors_sha = "<sha>";
```
After that, the server has to be restarted, or you have to send a GET request to its `/perf/onpush`
endpoint.
