Hi!

I’m trying to use JuliaDB. When I try to `add` it, I get the following incompatibility message:

```julia
(@v1.7) pkg> add JuliaDB
   Resolving package versions...
ERROR: Unsatisfiable requirements detected for package MLUtils [f1d291b0]:

```

I reckon that StatsBase and JuliaDB are incompatible. Have I understood the message correctly?  
Is there a solution to this problem?

Thanks a lot,  
Inbar

You haven’t understood it quite correctly. Let me post a screenshot - normally discouraged, but I’ll do it for the colours - of what happens when I try to add JuliaDB and MLUtils in a new environment [NB: don’t just dump all your projects into the main environment, work with project specific environments]:

 ![image](https://global.discourse-cdn.com/julialang/original/3X/6/c/6ca0cf802f2435eca833476fe691f875bbbf96c9.png)

hopefully this makes it clearer:

- both `MLUtils` and `JuliaDB` depend on `StatsBase`
- `MLUtils` requires `StatsBase >= 0.33`
- `JuliaDB` requires `StatsBase <= 0.32.2`

The best way around this would be to bump the compat bounds of `JuliaDB`, but unfortunately it hasn’t been updated in a while.

A hack would be to `dev` `JuliaDB` locally and just relax the compat to allow `StatsBase 0.33` to see if it works - if it does you could upstream that change (and maybe become a new `JuliaDB` maintainer!)

Given that JuliaDB.jl is not maintained currently could you say what is your usecase as maybe some alternatives could be recommended instead?

I try to teach myself statistics and (postgre)SQL at the same time, so instead of storing my simulation samples “manually” in a text file I wanted to save them to a database and pull them back later for further analysis.

You don’t need JuliaDB for that, see:

In particular using [GitHub - invenia/LibPQ.jl: A Julia wrapper for libpq](https://github.com/invenia/LibPQ.jl) in combination with [GitHub - JuliaData/DataFrames.jl: In-memory tabular data in Julia](https://github.com/JuliaData/DataFrames.jl) should be sufficient for most learning purposes.
