This tutorial will cover database design and modeling with MySQL Workbench. # Execute query sql = "SELECT * FROM iris" cursor.execute(sql) # Fetch all the records result = cursor.MySQL Workbench is a graphical visual database design tool with multiple functionalities. Query the database to check our workĪgain, let’s query the database to make sure that our inserted data has been saved correctly. By default, all rows will be written at once.ģ.2.1. chunksize writes records in batches of a given size at a time. ![]() if_exists = 'append'checks whether the table we specified already exists or not, and then appends the new data (if it does exist) or creates a new table (if it doesn’t).con = engine provides the connection details (recall that we created engine using our authentication details in the previous step).iris is the name of table into which we want to insert our DataFrame.format(user="root", db="irisdb")) # Insert whole DataFrame into MySQL irisData.to_sql('iris', con = engine, if_exists = 'append', chunksize = 1000,index=False) Inserting Pandas DataFrames into a Database Using the to_sql() Function # import the module from sqlalchemy import create_engine # create sqlalchemy engine engine = create_engine("mysql+pymysql://. # Execute query sql = "SELECT * FROM iris" cursor.execute(sql) # Fetch all the records result = cursor.fetchall() for i in result: print(i)ģ.2.
