It seems this [PR](https://github.com/k1LoW/tbls/pull/341) covers mysql, mssql and postgreSQL. Is there any other supported dbs with such functionality?

I see that * [mariaDB is based on mysql](https://github.com/k1LoW/tbls/blob/main/drivers/mariadb/mariadb.go#L16) so it should be covered within mentioned PR. * Same for [redshift](https://github.com/k1LoW/tbls/blob/main/drivers/redshift/redshift.go#L15) * snowflake is not covered :-( not sure how...

Hello there, checking oracle support now... I am not sure how to write a unit test for it properly as there is no kind of official docker image with oracle...
