google-big-queryHow do I query Google BigQuery using XML?

XML is not a supported query language for Google BigQuery. Instead, you should use the BigQuery Standard SQL syntax.

For example, the following query retrieves the total number of user sessions for each user:

SELECT user_id, COUNT(*) AS total_sessions
FROM `project.dataset.sessions_table`
GROUP BY user_id

The output of this query would be a table with two columns: user_id and total_sessions:

+---------+---------------+
| user_id | total_sessions|
+---------+---------------+
|    1234 |            10 |
|    5678 |            15 |
|    9012 |            20 |
+---------+---------------+

The query consists of three parts:

1. The SELECT clause which defines the columns to be returned in the results.
2. The FROM clause which defines the table from which the data should be retrieved.
3. The GROUP BY clause which defines the column by which the data should be grouped.
