Infoga dataram i postgresql sqlalchemy med idx autoincrement

Ett sätt (bland många) att göra detta skulle vara:

för att hämta maximalt Id och lagra den i en variabel (låt oss kalla den max_id ):

select max(Id) from quotes;

nu kan vi göra detta:

Original DF:

In [55]: quote_df
Out[55]:
      Adj_Close       Close        Date        High         Low        Open Symbol   Volume
0    170.572764  173.990005  2015-12-31  175.649994  173.970001  175.089996    DIA  5773400

215   88.893319   90.129997  2016-01-04   90.730003   89.360001   90.550003    IWN  2540600

[1404 rows x 8 columns]

nu kan vi öka indexet med max_id :

In [56]: max_id = 123456    # <-- you don't need this line... 

In [57]: quote_df.index += max_id

och ställ in index som Id kolumn:

In [58]: quote_df.reset_index().rename(columns={'index':'Id'})
Out[58]:

Nu borde det vara möjligt att skriva denna DF till PostgreSQL specificerande (index=False )
