Your imparting skills are quite impressive. I find it easy to understand. Nice video. How we can insert data from pandas by pd.to_sql method in a user defined column of a particular table?? Say i want to insert live dataframe (with changing source values, and with no timestamp) in a 2nd column of a sql table where the 1st column record the timestamp of storing the dataframe??? Valuable solution/ reply will be helpful for me. Thanks in advance
