**Steps to complete:**

1. [Run SQL script for permissions and create schema for Datafold](/integrations/databases/mysql#run-sql-script-and-create-schema-for-datafold)
2. [Configure your data connection in Datafold](/integrations/databases/mysql#configure-in-datafold)

### Run SQL script and create schema for Datafold

To connect to MySQL, create a user with read-only access to all tables you wish to diff. Include read and write access to a Datafold-specific dataset:

```Bash theme={null}
-- Create a temporary dataset for Datafold to utilize
CREATE DATABASE IF NOT EXISTS datafold_tmp;

-- Create a Datafold user
CREATE USER 'datafold_user'@'%' IDENTIFIED BY 'SOMESECUREPASSWORD';

-- Grant read access to diff tables in YourSchema
GRANT SELECT ON `YourSchema`.* TO 'datafold_user'@'%';

-- Grant access to all tables in a datafold_tmp database
GRANT ALL ON `datafold_tmp`.* TO 'datafold_user'@'%';

-- Apply the changes
FLUSH PRIVILEGES;
```

Datafold utilizes a temporary dataset, named `datafold_tmp` in the above script, to materialize scratch work and keep data processing in the your warehouse.
