MindsDB and SQL Alchemy |
SQL Alchemy |
SQL Alchemy is a Python SQL toolkit, that provides object-relational mapping features for the Python programming language.
SQL Alchemy facilitates working with databases and Python. You can download it here or run a pip install sqlalchemy.
Please follow the instructions below to connect your MindsDB to SQL Alchemy.
You can use the Python code below to connect your MindsDB database to SQL Alchemy. Make sure you have the *pymysql* module installed before executing the Python code. To install it, run the `pip install pymysql` command.
```python
from sqlalchemy import create_engine
user = 'mindsdb'
password = ''
host = '127.0.0.1'
port = 47335
database = ''
def get_connection():
return create_engine(
url="mysql+pymysql://{0}:{1}@{2}:{3}/{4}".format(user, password, host, port, database)
)
if __name__ == '__main__':
try:
engine = get_connection()
engine.connect()
print(f"Connection to the {host} for user {user} created successfully.")
except Exception as ex:
print("Connection could not be made due to the following error: \n", ex)
```
Please note that we use the following connection details:
- Username is `mindsdb`
- Password is left empty
- Host is `127.0.0.1`
- Port is `47335`
- Database name is left empty
To create a database connection, execute the code above. On success, the following output is expected:
```bash
Connection to the 127.0.0.1 for user mindsdb created successfully.
```
</Tab>
<Tab title="MindsDB Cloud">
You can use the Python code below to connect your MindsDB account to SQL Alchemy.
Make sure you have the *pymysql* module installed before executing the Python code. To install it, run the `pip install pymysql` command.
```python
from sqlalchemy import create_engine
user = 'MindsDB Cloud username' # your Mindsdb Cloud email address is your username
password = 'MindsDB Cloud password' # replace this value
host = 'cloud.mindsdb.com'
port = 3306
database = ''
def get_connection():
return create_engine(
url="mysql+pymysql://{0}:{1}@{2}:{3}/{4}".format(user, password, host, port, database)
)
if __name__ == '__main__':
try:
engine = get_connection()
engine.connect()
print(f"Connection to the {host} for user {user} created successfully.")
except Exception as ex:
print("Connection could not be made due to the following error: \n", ex)
```
Please note that we use the following connection details:
- Username is your MindsDB Cloud email address
- Password is your MindsDB Cloud password
- Host is `cloud.mindsdb.com`
- Port is `3306`
- Database name is left empty
To create a database connection, execute the code above. On success, the following output is expected:
```bash
Connection to the cloud.mindsdb.com for user MindsDB-Cloud-Username created successfully.
```
</Tab>
<Tab title="MindsDB Pro">
You can use the Python code below to connect your MindsDB account to SQL Alchemy.
Make sure you have the *pymysql* module installed before executing the Python code. To install it, run the `pip install pymysql` command.
```python
from sqlalchemy import create_engine
user = 'MindsDB Cloud username' # your Mindsdb Cloud email address is your username
password = 'MindsDB Cloud password' # replace this value
host = '<dedicated instance ip>'
port = 3306
database = ''
def get_connection():
return create_engine(
url="mysql+pymysql://{0}:{1}@{2}:{3}/{4}".format(user, password, host, port, database)
)
if __name__ == '__main__':
try:
engine = get_connection()
engine.connect()
print(f"Connection to the {host} for user {user} created successfully.")
except Exception as ex:
print("Connection could not be made due to the following error: \n", ex)
```
Please note that we use the following connection details:
- Username is your MindsDB Cloud email address
- Password is your MindsDB Cloud password
- Host is the IP address of your dedicated instance
- Port is your custom port
- Database name is left empty
To create a database connection, execute the code above. On success, the following output is expected:
```bash
Connection to the cloud.mindsdb.com for user MindsDB-Cloud-Username created successfully.
```
</Tab>
The Sqlachemy `create_engine` is lazy. This implies any human error when entering the connection details would be undetectable until an action becomes necessary, such as when calling the `execute` method to execute SQL commands.
Now that you are all set, we recommend you check out our Tutorials and Community Tutorials sections, where you'll find various examples of regression, classification, and time series predictions with MindsDB.
To learn more about MindsDB itself, follow the guide on MindsDB database structure. Also, don't miss out on the remaining pages from the SQL API section, as they explain a common SQL syntax with examples.
