Google BigQuery functions allow you to perform various operations on your data. To use the functions, you must first create a BigQuery dataset.
Example code
# Create a BigQuery dataset

Once the dataset is created, you can use the BigQuery functions to perform various operations on the data. Here is a list of some of the operations you can perform:
-
Select - Select data from a table.
Example code:
# Select data from a table bq query --use_legacy_sql=false 'SELECT * FROM mydataset.mytable'

-
Insert - Insert data into a table.
Example code:
# Insert data into a table bq query --use_legacy_sql=false 'INSERT INTO mydataset.mytable (Col1, Col2) VALUES (4, "Lemon")'
Output:
Inserted 1 row(s) in 0.7s
-
Update - Update data in a table.
Example code:
# Update data in a table bq query --use_legacy_sql=false 'UPDATE mydataset.mytable SET Col2 = "Mango" WHERE Col1 = 2'
Output:
Updated 1 row(s) in 0.7s
-
Delete - Delete data from a table.
Example code:
# Delete data from a table bq query --use_legacy_sql=false 'DELETE FROM mydataset.mytable WHERE Col1 = 3'
