I am trying to figure out why this query is returning a list of lists rather than a list of dictionaries. I suspect it has something to do with either the join or the 'as' portion of the query. Any insight into this would be appreciated.
Code Below:
try:
#Connect to database
connection = pymysql.connect(
dbConfig.host,
user=dbConfig.user,
passwd=dbConfig.password,
db=dbConfig.db,
ssl=dbConfig.ssl,
connect_timeout=5
)
cursor = connection.cursor(pymysql.cursors.DictCursor)
print(cursor)
except Exception:
print("Error connecting to db")
return
sql = ('select retsub.sms_credits as sms_balance, '
'retsub.subscription_credit as mms_balance, '
'mg.merchants_id, '
'mg.store_name, '
'mg.email_representative from mg_groupdeals_merchants mg '
'left join mg_giftdigital_retailer_retailersubscription retsub on (mg.merchants_id=retsub.merchant_id) '
'left join mg_api_event_mapping event on(mg.merchants_id=event.merchant_id) '
'where retsub.sms_credits is not null '
'and event.merchant_id is not null '
'group by merchants_id;')
cursor.execute('select * from mg_giftdigital_user_sessions')
print(cursor.fetchall())
cursor.execute(sql)
print(cursor.fetchall())
Which returns in order of execution:
First: A list of dictionaries matching the query with column_name:value, which is what I expect.
Second: A list like this (('63741', '7598.7924528302', merchant_id, 'store_name'),)
Try:
connection = pymysql.connect(
dbConfig.host,
user=dbConfig.user,
passwd=dbConfig.password,
db=dbConfig.db,
ssl=dbConfig.ssl,
connect_timeout=5
cursorclass=pymysql.cursors.DictCursor
)
I changed the cursor type to be inside the connect method
