Python Insert Into Table

Invoegen van tabel

Om tabellen in MySQL te vullen, gebruik dan de "INSERT INTO"-zinnen.

Example

Record invoegen in tabel "customers":

import mysql.connector
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)
mycursor = mydb.cursor()
sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = ("John", "Highway 21")
mycursor.execute(sql, val)
mydb.commit()
print(mycursor.rowcount, "record inserted.")

Run Instance

Belangrijk:Let op de zin: mydb.commit(). Er moet een wijziging worden aangebracht, anders zal de tabel geen enkele verandering ondergaan.

Invoegen van meerdere rijen

Om meerdere rijen in de tabel in te voegen, gebruik dan: executemany() Methode.

De tweede parameter van de executemany() methode is een lijst van tuples, die de te inserteren gegevens bevat:

Example

Gegevens invullen van tabel "customers":

import mysql.connector
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)
mycursor = mydb.cursor()
sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = [
  ('Peter', 'Lowstreet 4'),
  ('Amy', 'Apple st 652'),
  ('Hannah', 'Mountain 21'),
  ('Michael', 'Valley 345'),
  ('Sandy', 'Ocean blvd 2'),
  ('Betty', 'Green Grass 1'),
  ('Richard', 'Sky st 331'),
  ('Susan', 'One way 98'),
  ('Vicky', 'Yellow Garden 2'),
  ('Ben', 'Park Lane 38'),
  ('William', 'Central st 954'),
  ('Chuck', 'Main Road 989'),
  ('Viola', 'Sideway 1633')
]
mycursor.executemany(sql, val)
mydb.commit()
print(mycursor.rowcount, "was inserted.")

Run Instance

Get Inserted ID

You can ask the cursor object to get the id of the newly inserted row.

Note:If more than one row is inserted, the id of the last inserted row is returned.

Example

Insert one row and return id:

import mysql.connector
mydb = mysql.connector.connect(
  host="localhost",
  user="yourusername",
  passwd="yourpassword",
  database="mydatabase"
)
mycursor = mydb.cursor()
sql = "INSERT INTO customers (name, address) VALUES (%s, %s)"
val = ("Michelle", "Blue Village")
mycursor.execute(sql, val)
mydb.commit()
print("1 record inserted, ID:", mycursor.lastrowid)
