I have code similar to the one below:
# pip install pymysql
# pip install sqlalchemy
import pandas as pd
import sqlalchemy
engine = sqlalchemy.create_engine('mysql+pymysql://username:password@localhost:3306/db_name')
query = '''
select * from table_name
'''
df = pd.read_sql_query(query, engine)
print(df)
I would like to modify the select statement to just list specific columns and not all of them, as above. For example the csv file the code reads has a column name Player. To select the column Player, I tried
query = '''
select Player from table_name
'''
but it does not work. How can I fix this?
This solved it, simple but it did not occur to me. I needed backward slashes with quotes, not just quotes to surround Player.
