Generate Multiple files Table Structure and create table - pandas

Question

I'm trying to Generate Multiple files Table Structure to Snowflake via Python
I have list of files in Directory, I want to read data from files create the tables dynamically in snowflake using file names.
below is what I tried so far
# Generate Multiple files Table Structure to Snowflake via Python
import os
from os import path
import pandas as pd
import snowflake.connector
from snowflake.sqlalchemy import URL
from sqlalchemy import create_engine
from snowflake.connector.pandas_tools import write_pandas, pd_writer
dir = r"D:\Datasets\users_dataset"
engine = create_engine(URL(
account='<account>',
user='<user>',
password='<password>',
role='ACCOUNTADMIN',
warehouse='COMPUTE_WH',
database='DEM0_DB',
schema='PUBLIC'
))
connection = engine.connect()
connection.execute("USE DATABASE DEMO_DB")
connection.execute("USE SCHEMA PUBLIC")
results = connection.execute('USE DATABASE DEMO_DB').fetchone()
print(results)
# read the files from the directory and split the filename and extension
for file in os.listdir(dir):
name, extr = path.splitext(file)
print(name)
file_path = os.path.join(dir, file)
print(file_path)
df = pd.read_csv(file_path, delimiter=',')
df.to_sql(name, con=engine, index=False)
I'm getting below error
sqlalchemy.exc.ProgrammingError: (snowflake.connector.errors.ProgrammingError) 090105 (22000): Cannot perform CREATE TABLE. This session does not have a current database. Call 'USE DATABASE', or use a qualified name.
[SQL:
CREATE TABLE desktop (
"[.ShellClassInfo]" FLOAT
)
]
(Background on this error at: https://sqlalche.me/e/14/f405)
I checked for permission issues on snowflake, and I haven't found any issues.
Can someone please help with this error

Answer 1

At the create_engine the database is called DEM0_DB instead of DEMO_DB:
engine = create_engine(URL(
...
#database='DEM0_DB',
database='DEMO_DB',
schema='PUBLIC'
))
