My plan is to insert a date (day_of_test) into a MySql database where the data format is referenced as date.
I had to keep the syntax in the format you see below. But unfortunately my attempts to store the date specifically as a string in the syntax VALUES(%s...) doesn't seem to work.
Does anyone know the easiest way to adjust the syntax to successfully insert day_of_test?
Thank you all
import mysql.connector
mydb = mysql.connector.connect(host="34.xxx.xxx.xxx", user="xxxx", password="xxxxx", database='btc-analysis-db')
c = mydb.cursor()
btc_est = 150.2
sap_close = 100.23
gold_close = 120.2
bonds_close = 210.12
btc_actual = 130.12
day_of_test = "2022-04-20"
c = mydb.cursor()
c.execute(
"INSERT INTO `ML1`(`day_of_test`, `btc_est`, `sap_close`, `bonds_close`, `gold_close`, `btc_actual`) VALUES (%s, %d, %d, %d, %d, %d );" % (
day_of_test, btc_est, sap_close, bonds_close, gold_close, btc_actual))
mydb.commit()
c.execute("select * from ML1")
result = c.fetchall()

If you are using python string format, then you are missing quotes around the date value, your syntax should be:
c.execute( "INSERT INTO `ML1`(`day_of_test`, `btc_est`, `sap_close`, `bonds_close`, `gold_close`, `btc_actual`) VALUES ('%s', %d, %d, %d, %d, %d);" % ( day_of_test, btc_est, sap_close, bonds_close, gold_close, btc_actual))But you shouldn't do that. You should use prepared statements (to avoid SQL injection and other problems), and your syntax should look like this:
c.execute( "INSERT INTO `ML1`(`day_of_test`, `btc_est`, `sap_close`, `bonds_close`, `gold_close`, `btc_actual`) VALUES (%s, %s, %s, %s, %s, %s);", ( day_of_test, btc_est, sap_close, bonds_close, gold_close, btc_actual))
