oracle

Sometimes it is needed to store compressed data in the DB. Unfortunately not all the DBs have built-in compression and FUSE compressed FSes are not available for every OS. So it may make sense to store compressed binary blobs in the DB.

Unfortunately when one sees them in DBeaver he sees them compressed, but often they are needed uncompressed. So it'd be nice to have a feature to decompress the

linq2db uses nvl to translate ??, which is nice because it's shorter than SQL standard coalesce.

The trick with nvl is that it only accepts 2 parameters, whereas coalesce accepts many.

In our codebase, we have a query that computes an error message based on a list of checks, it looks like this:
