The backup command will copy tables completely, but in the case of conflicting table names, the destination gets overwritten silently. That might not be what you want here.

I'm nervous about needing to set the rules for how duplicate tables should be merged though. This feels like a complex topic - one where there isn't necessarily an obviously ""correct"" way of doing it, but where different problems that people are solving might need different merging approaches.

Likewise, merging isn't just a database-to-database thing at that point - I could see a need for merging two tables using similar rules to those used for merging two databases.

So I think I'd want to have some good concrete use-cases in mind before trying to design how something like this should work. Will leave this thread open for people to drop those in!","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",1383646615,Ability to merge databases and tables,

```
sqlite-utils merge animals.db cats.db dogs.db
```

similar to `zip`, `ogr2ogr`, etc

Actually I think this might already be possible within `ogr2ogr`. I don't believe spatial data is a requirement though it might add an `ogc_id` column or something

```
cp cats.db animals.db
ogr2ogr -append animals.db dogs.db
ogr2ogr -append animals.db another.db
