import sqlite3
my_path="D:\\testing\\sqlite\\my_db.db" #Change the path
my_conn = sqlite3.connect(my_path)
print("Connected to database successfully")
Using SQLAlchemy
from sqlalchemy import create_engine
from sqlalchemy.exc import SQLAlchemyError
my_path="D:\\testing\\sqlite\\my_db.db" #Change the path
my_conn = create_engine("sqlite:///"+ my_path)
We will use read_sql() to create the DataFrame by using the query.
from sqlalchemy import create_engine
from sqlalchemy.exc import SQLAlchemyError
my_path='G:\\My Drive\\testing\\my_db\\my_db.db'
my_conn = create_engine("sqlite:///"+ my_path)
import pandas as pd
try:
query="SELECT * FROM student"
df = pd.read_sql(query,my_conn,index_col='id')
print(df.head()) # Print top 5 rows as sample
except SQLAlchemyError as e:
#print(e)
error = str(e.__dict__['orig'])
print(error)
else:
print("DataFrame created successfully..")
Using the Pandas DataFrame df, we will use set_dataframe() to add the dataframe to google sheets.
import pygsheets
path='G:\\My drive\\testing\\google-sheet\\creds1.json' # change path
gc=pygsheets.authorize(service_account_file=path)
sh=gc.open('my_gsheets1') # Open google sheet
wk1=sh[0] # select first work sheet
wk1.clear() # remove previous data if any
wk1.set_dataframe(df,(1,1),copy_index=True, extend=True)

from sqlalchemy import create_engine
