BigQuery Remove Duplicate Keys From Table

#standardSQL
CREATE OR REPLACE TABLE `myproject.datasetID.tableID` AS
SELECT * FROM (
  SELECT AS VALUE ANY_VALUE(new_table)
  FROM `myproject.dev.sample` AS new_table
  GROUP BY key1 #,key2
)

Here is what the above code is Doing:
1. Create a new table in the datasetID.tableID location
2. Select all the columns from the sample table
3. Group by the key1 column
4. Use the ANY_VALUE function to return a single row from the group
