How to run parameterized queries on BigQuery
BigQuery supports query parameters to help prevent SQL injection when queries are constructed using user input. This feature is only available with standard SQL syntax. (Query parameters can be used as substitutes for arbitrary expressions. Parameters cannot be used as substitutes for identifiers, column names, table names, or other parts of the query)
@val '123'; SELECT * FROM [project_id:my_dataset.my_table] where name=@val
You can run a parameterized query like the above only from API or using BQ utility. You CANNOT run this using the Web UI
