Select From a Table
To select from a table in MySQL, use the "SELECT" statement:
Example
Select all records from the "customers" table, and display the
result:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
mycursor =
mydb.cursor()
mycursor.execute("SELECT * FROM customers")
myresult = mycursor.fetchall()
for x in myresult:
print(x)
Run example »
Note: We use the fetchall()
method, which fetches all rows from the last executed statement.
Selecting Columns
To select only some of the columns in a table, use the "SELECT" statement
followed by the column name(s):
Example
Select only the name and address columns:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
mycursor = mydb.cursor()
mycursor.execute("SELECT name,
address FROM
customers")
myresult = mycursor.fetchall()
for x in myresult:
print(x)Run example »
Using the fetchone() Method
If you are only interested in one row, you can use the fetchone() method.
The fetchone() method will return the first row of
the result:
Example
Fetch only one row:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
mycursor =
mydb.cursor()
mycursor.execute("SELECT * FROM customers")
myresult = mycursor.fetchone()
print(myresult)Run example »
