Table to Storage SQL file

This is the description of the SQL file used for a Table to Storage data operation.

To run a Table to Storage data operation, you first need to prepare a SQL query that will extract the data to export.

The SQL file must contains a BigQuery Standard SQL query. You can write it directly in the query editor of BigQuery and then save it to a .sql file.


SELECT * FROM 'myproject.datalake.sales'

This query will be executed when the data operation is deployed, and the result will display in the CSV export file and the table copy if specified.

You can now use constants with context but only if you stated version :"3" in the global parameters of the configuration and if your tailer SDK version is 1.3.9 or later. See here for the constants with context. For example:
