Google BigQuery Delete Rows?

Question

Anyone know of any plans to add support for delete parts of data from a table in Google Bigquery? The issue we have right now is we are using it for analytics of data point

Answer 1

For deleting records in Big query, you have to first enable standard sql.

Steps for enabling Standard sql

1. Open the BigQuery web UI.
2. Click Compose Query.
3. Click Show Options.
4. Uncheck the Use Legacy SQL checkbox.

This will enable the the BigQuery Data Manipulation Language (DML) to update, insert, and delete data from the BigQuery tables

Now, you can write the plain SQL query to delete the record(s)

DELETE [FROM] target_name [alias] WHERE condition
