The syntax to connect to BigQuery via SQL Editor is shown below
To include all table in ProjectID, do not include DefaultDataset or FilterTablesOnDefaultDataset parameters
CREATE DATASOURCE GOOGLE_BIGQUERY OPTIONS (
jdbcdriver "com.simba.googlebigquery.jdbc.Driver",
jdbcurl "jdbc:bigquery://https://www.googleapis.com/bigquery/v2:443",
ProjectID "<projectID>",
DefaultDataset "<dataset>",
FilterTablesOnDefaultDataset "1",
OAuthType "<oauthType>",
OAuthServiceAcctEmail "<oauthServiceAccountEmail>",
OAuthPvtKeyPath "<oauthPrivateKeyPath>"
);
REGISTER DATASOURCE TABLES FROM GOOGLE_BIGQUERY;
Example connection string:
CREATE DATASOURCE GOOGLE_BIGQUERY OPTIONS (
jdbcdriver "com.simba.googlebigquery.jdbc.Driver",
jdbcurl "jdbc:bigquery://https://www.googleapis.com/bigquery/v2:443",

Step 2: Select “Create new key”
Step 3: Create JSON key
Where to store and access your OAuthPvtKey in Zetaris
You are able to store your OAuthPvtKey in either the local file system which the backend runs on, or in the NDP file system in the "key-trust-store" folder (after manually uploading it), e.g.
NDP file system
If on the local file system, just provide the path e.g. /path/to/file/[OAuthPvtKey].json
If from NDP file system, ensure in format like dffs:///[OAuthPvtKey].json
