Create a Google BigQuery Connection
To access your data stored on a Google BigQuery database, you will need to know the server and database name that you want to connect to, and you must have access credentials. Once you have created a connection to a Google BigQuery database, you can select data from the available tables and then load that data into your app or document.
In Qlik Sense, you connect to a Google BigQuery database through the Add data dialog or the Data load editor.
In QlikView you connect to a Google BigQuery database through the Edit Script dialog.
Creating a trusted storage certificate
If you do not have an appropriate storage certificate to use with the connector in your Windows environment, you will need to download one.
Do the following:
-
Go to Google Trust Services - Repository and navigate to the Download CA certificate section.
-
Select the GTS Root R2 certificate with fingerprint SHA1: 8d:25:cd:97:22:9d:bf:70:35:6b:da:4e:b3:cc:73:40:31:e2:4c:f0:0f:af:cf:d3:2d:c7:6e:b5:84:1c:7e:a8 .
-
Click Action and download the certificate as a PEM file.

| Allow Large Result Sets | This option specifies the connector's response to query results larger than 128MB when using Legacy SQL. | No |
| Dataset Name For Large Result Sets | The ID of the existing BigQuery dataset that you want to use to store temporary tables for large result sets. Only specify a value for this option if you want to enable support for large result sets. | No |
Miscellaneous properties
| Property | Description |
|---|---|
| Query timeout | Amount of time before a data load query times out. Can be set from 30 seconds to 65535 seconds. Default is 30 seconds. |
| Retry timeout | The length of time, in seconds, for which the connector retries a failed API call before timing out. The specified value must be an integer. A value of 0 indicates no timeout. Default value is 300. |
