Ok I am new to sqlite and python in general so please be nice =)
I have a simple dictionary -



time = data[0]['timestamp']
price = data[0]['price']

myprice = 'Date':time,'price':price


myprice looks like this (time is a timestamp) -



'Date': 1553549093, 'price': 1.7686


I now want to add the data to sqlite3 database...so I created this -



#Create database if not exist...

db_filename = 'mydb_test.db'
connection = sqlite3.connect(db_filename)

#Get a SQL cursor to be able to execute SQL commands...

cursor = connection.cursor()

#Create table

sql = '''CREATE TABLE IF NOT EXISTS TEST
(PID INTEGER PRIMARY KEY AUTOINCREMENT,
DATE TIMESTAMP,
PRICE FLOAT)'''

#Now lets execute the above SQL

cursor.execute(sql)


#Insert data in sql

sql2 = ("INSERT INTO GBPCAD VALUES (?,?)", [(myprice['Date'],myprice['price'])])

cursor.execute(sql2)
cursor.commit()
connection.close()


But when executing this code I get ValueError: operation parameter must be str



What am I doing wrong?

          Pass the arguments of the insert statement in execute():



          sql2 = "INSERT INTO GBPCAD (DATE, PRICE) VALUES (?,?)"
          cursor.execute(sql2, (myprice['Date'], myprice['price']))


          Also include in the insert statement the names of the columns.
