Python MySQL Create Database
Creating a Database
To create a database in MySQL, use the "CREATE DATABASE" statement:
Example
create a database named "mydatabase":
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword"
)
mycursor = mydb.cursor()
mycursor.execute("CREATE DATABASE
mydatabase")
Run example »
If the above code was executed with no errors, you have successfully created a database.
Check if Database Exists
You can check if a database exist by listing all databases in your system by using the "SHOW DATABASES" statement:
Example
Return a list of your system's databases:
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword"
)
mycursor = mydb.cursor()
mycursor.execute("SHOW DATABASES")
for x in mycursor:
print(x)
Run example »
Or you can try to access the database when making the connection:
Example
Try connecting to the database "mydatabase":
import mysql.connector
mydb = mysql.connector.connect(
host="localhost",
user="yourusername",
passwd="yourpassword",
database="mydatabase"
)
Run example »
If the database does not exist, you will get an error.
