Create table from dataframe?

[EgorKraevTransferwise]

Is there a way to automatically create a table matching the column types of a dataframe, similar to pandas.DataFrame.to_sql()?

i can see that there's no such function currently. but is this feature welcomed? can I send a PR if I managed to implement it? @kszucs

Definitely!

@timfeirg is it done?

[timfeirg]

there's this package https://github.com/cloudflare/sqlalchemy-clickhouse that already can generate create table statements, I've tried but it is clearly not finished yet, but we're better off improving things in that repo, because pandas already supports sqlalchemy.

Note that this package will switch to use columnar output formats in the future, once clickhouse extends its type support for these formats, see #29 for reference.
