The process of combining tables in BigQuery involves using SQL statements to join the tables based on one or more common fields. The following steps outline the process:

  1. Identify the common fields between the tables that need to be joined.

  2. Use the SQL statement "SELECT" to select the columns from the tables that need to be combined.

  3. Use the SQL statement "FROM" to specify the tables that need to be combined.

  4. Use the SQL statement "JOIN" to join the tables based on the common fields.

  5. Specify the type of JOIN to be used (such as INNER JOIN, LEFT JOIN, etc.), based on the data you want to retrieve.

  6. Add additional conditions to the SQL statement, such as a WHERE clause or ORDER BY, to further refine the results.

  7. Execute the SQL statement to combine the tables and create a new combined dataset.
