问题 Consider the following scenario (if it helps think Northwind Orders / OrderDetails). I have two tables LandingHeaders and LandingDetails, that record details about commercial fishing trips.

问题 Ahoi there, is there a possibility of using the revoscalepy package to insert values into a table? I would expect something along the lines of: import pandas as pd from revoscalepy import rx_write_to_db, RxOdbcData a_df = pd.DataFrame([[0, 1], [2, 3]], columns=[...]) rx_write_to_db(RxOdbcData(connection_string=con_str, ...), data=a_df) But I couldn't find anything like this. The closest option appears to be rx_write_object, which dumps the dataframe as a binary into the table. More

After the iteration finishes I'm not able to pull the values from this newly created table. I wrote a little comment next
