google-big-queryHow do I update data in Google BigQuery?

Updating data in Google BigQuery is a straightforward process. The simplest way to do this is to use the UPDATE statement in BigQuery. This statement allows you to update existing records in a table or view.

Here is an example of the UPDATE statement in BigQuery:

UPDATE dataset.table
SET column1 = value1,
    column2 = value2
WHERE condition;

The UPDATE statement first specifies the dataset and table to update. Then, the SET clause specifies the columns to update and their new values. Finally, the WHERE clause specifies which records to update.

Here is an example of the UPDATE statement in action:

UPDATE dataset.table
SET column1 = 'Updated Value',
    column2 = 'Updated Value'
WHERE column1 = 'Old Value';

This statement will update the records in dataset.table where column1 is equal to Old Value. The values of column1 and column2 will be set to Updated Value.

• UPDATE dataset.table - This line specifies the dataset and table to update.
