#Remarks

Use this connector to execute SQL queries against a Snowflake database.

SQL Parameters via Custom Properties

Flowgear Custom Properties can be added to this Node to make SQL parameters available in the Query Property. Use of a Custom Property is shown in the linked example workflow (see Examples below).

Other Nodes for SQL databases

If you are updating values in a table based on keys, consider using Snowflake SQL Table Update instead of crafting update statements.

If you need to integrate with a non-Microsoft SQL database, refer to Integrating with SQL Databases for additional information and connection strings.

Activate OAuth

You will need to activate OAuth on your Snowflake account to be able to use this connector. To activate OAuth you must create a security integration.
To do this you must navigate to the SQL Worksheet (accessed by clicking on the + in the left menu) and create a new SQL Worksheet.

You will then have to run the following command in that worksheet

CREATE OR REPLACE SECURITY INTEGRATION 
"Flowgear"
TYPE = OAUTH
OAUTH_CLIENT = CUSTOM
OAUTH_CLIENT_TYPE = "CONFIDENTIAL"
OAUTH_REDIRECT_URI = "https://app.flowgear.net/r/auth"
OAUTH_ISSUE_REFRESH_TOKENS = true
ENABLED = true;

This will create a security integration on your account that can then be used to create a connection. You will note that the creation does not supply you with the client secrets needed. To get those you must run a separate command.

SELECT SYSTEM$SHOW_OAUTH_CLIENT_SECRETS( 'Flowgear' )

You can then copy the value returned from that as is and paste it in the ClientSecrets. The object will be parsed to get the client id/secret needed for OAuth.

By default, Snowflake prevents the ACCOUNTADMIN, ORGADMIN, GLOBALORGADMIN, and SECURITYADMIN roles from authenticating. To allow these roles to authenticate you will need to run the follow command.

ALTER ACCOUNT SET OAUTH_ADD_PRIVILEGED_ROLES_TO_BLOCKED_LIST = false;
