MySQL Driver v0.1.0¶
Driver Version v0.1.0 Tested With MySQL 9.4
This driver provides access to MySQL , a free and open-source relational database management system.
Installation¶
The MySQL driver can be installed with dbc :
dbc install mysql
Connecting¶
To connect, edit the uri option below to match your environment and run the following:
from adbc_driver_manager import dbapi
conn = dbapi.connect(
driver="mysql",
db_kwargs = {
"uri": "root@tcp(localhost:3306)/demo"
}
)
Note: The example above is for Python using the adbc-driver-manager package but the process will be similar for other driver managers.
