Testing and Using the SNOMED CT Database
Open the SNOMEDCT Connection
- Open MySQL Workbench
- Select the SNOMED CT Connection
Test the SNOMED CT Database
To test the loaded SNOMED CT database open one of the example queries in the SnomedCtRfsMySql/mysql_examples folder.
- Click open SQL button
in the toolbar in the toolbar - Find the mysql_examples folder in the SnomedCtRfsMySql subfolder of your home directory.
- Select and open one of the queries
The query should be display as shown below
- Click the lightning icon
to run the query
The results of running the query should be displayed as below
Using the SNOMED CT Database
The SNOMED CT database can be used in different ways:
- Running example SQL queries in the SnomedRfsMySql package.
- Running queries provided as part of a SNOMED CT E-Learning assignment.
- Using example SQL queries as templates for your own queries.
- Running SQL queries you have written yourself from scratch.
You can run your SQL queries in MySQL Workbench as described in the previous section. Additionally these queries can be run using the MySQL command line interface or through a MySQL connector for one of the programming languages listed at: https://dev.mysql.com/downloads/.
If you are using example queries as templates for your own queries alway copy the query first so that you do not overwrite the original example query.
- If you accidentally overwrite an example query, you can download the SnomedRfsMySql.zip file again and extract the example queries folder.
Managing MySQL Accounts
The "root" user account is typically used for importing the SNOMED CT release files. However, you should create additional MySQL accounts for database users that do not have administrator rights. Ideally the name of these MySQL accounts should match the Mac username of the user as this simplifies call the mysql command line tool and the use of MySQL connectors.
To create user accounts in the MySQL Workbench select the Administration tab (see below) and select Users and Privileges (see below).
Set up the account details and access permissions.
- In this example an account with the username newuser account is being created as shown below:
- In the schema privileges the newuser is given access to the snomedct database schema:
- Within the snomedct database the rights of this newuser are limited to the following actions.
