An option for selecting all columns

[ghost]

In the SELECT(String... columns) it will be better if no arguments are accounted to all columns instead of throwing an exception, writing all column names can get tedious will be happy to do a PR for this

I think it's good practice to only specify which columns you want to read to reduce the amount of loaded data.

Nevertheless, you can write SELECT("*") which is mor expressive since you know what "*" means

agrees, that works with the current logic as well added a javadoc comment to make this more obvious
