Import from Pandas

CREATE TABLE AS and INSERT INTO can be used to create a table from any query. We can then create tables or insert into existing tables by referring to referring to the Pandas DataFrame in the query.

import duckdb
import pandas

# Create a Pandas dataframe
my_df = pandas.DataFrame.from_dict({'a': [42]})

# create the table "my_table" from the DataFrame "my_df"
# Note: duckdb.sql connects to the default in-memory database connection
duckdb.sql("CREATE TABLE my_table AS SELECT * FROM my_df")

# insert into the table "my_table" from the DataFrame "my_df"
duckdb.sql("INSERT INTO my_table SELECT * FROM my_df")
