Python MySQL Insert Into Table
Insert Into Table
To fill a table in MySQL, use the "INSERT INTO" statement.
Example
Insert a record in the "customers" table:
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 example »
Important!: Notice the statement:
mydb.commit(). It is required to make the
changes, otherwise no
changes are made to the table.
Insert Multiple Rows
To insert multiple rows into a table, use the
executemany() method.
The second parameter of the executemany() method
is a list of tuples, containing the data you want to insert:
Example
Fill the "customers" table with data:
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.")

Get Inserted ID
You can get the id of the row you just inserted by asking the cursor object.
Note: If you insert more that one row, the id of the last inserted row is returned.
Example
Insert one row, and return the 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)
