Python MySQL Update Table [Guide]
March 9, 2021 - Or when you want to update details dynamically by passing Python variables into a query. Such as setting column value using the variable. It is always best practice to use parameterized query and prepared statement, i.e., placeholders ( %s ) inside any SQL statements that contain input from users. This helps us prevent SQL injection and other SQL issues. Read more on What is a Parameterized Query and its performance benefits. Let’ s see the example program now. import mysql.connector def update_laptop_price(id, price): try: connection = mysql.connector.connect(host='localhost', database='ele

It should be:
cursor.execute ("""
UPDATE tblTableName
SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))
You can also do it with basic string manipulation,
cursor.execute ("UPDATE tblTableName SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s WHERE Server='%s' " % (Year, Month, Day, Hour, Minute, ServerID))
but this way is discouraged because it leaves you open for SQL Injection. As it's so easy (and similar) to do it the right waytm. Do it correctly.
The only thing you should be careful, is that some database backends don't follow the same convention for string replacement (SQLite comes to mind).

You've got the syntax all wrong:
cursor.execute ("""
UPDATE tblTableName
SET Year=%s, Month=%s, Day=%s, Hour=%s, Minute=%s
WHERE Server=%s
""", (Year, Month, Day, Hour, Minute, ServerID))
