google-big-queryHow do I use Google BigQuery functions?

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
bq mk mydataset

Output example

Dataset 'mydataset' successfully created.

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:

1. Select - Select data from a table.

   Example code:

   # Select data from a table
   bq query --use_legacy_sql=false 'SELECT * FROM mydataset.mytable'

   Output:

   +--------+----------+
   |  Col1  |  Col2    |
   +--------+----------+
   |  1     |  Apple   |
   |  2     |  Orange  |
   |  3     |  Banana  |
   +--------+----------+

2. 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

3. 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

4. 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'

   Output:

   Deleted 1 row(s) in 0.7s

These are just a few of the operations you can perform with Google BigQuery functions. For more information, please refer to the BigQuery Documentation.
