Pandas to_sql fails on duplicate primary key

Question

I\'d like to append to an existing table, using pandas df.to_sql() function.

I set if_exists=\'append\', but my table has primary keys.

Answer 1

There is unfortunately no option to specify "INSERT IGNORE". This is how I got around that limitation to insert rows into that database that were not duplicates (dataframe name is df)

for i in range(len(df)):
    try:
        df.iloc[i:i+1].to_sql(name="Table_Name",if_exists='append',con = Engine)
    except IntegrityError:
        pass #or any other action
