It could be Better after that.

cardillo commented 6 years ago

Agree this would be a useful feature, I’ll gladly review a pull request or take a look at adding it myself.

Jungle666 commented 6 years ago

thanks for you answers, another question is ，Is there a easy way to convert “list< bean >” to a dataframe?

cardillo commented 6 years ago

No, but you can probably look at something like BeanUtils to copy from the bean into a row which you can append to a data frame.

As of v1.9 -- see https://cardillo.github.io/joinery/v1.9/api/reference/joinery/DataFrame.html#readSql(java.sql.Connection,%20java.lang.String) for details.
