google-big-queryHow do I create a schema for Google BigQuery?
Creating a schema for Google BigQuery is easy and straightforward. The basic syntax is CREATE TABLE [table_name] (column_name data_type, column_name data_type, ...). To illustrate, here is an example of creating a table with three columns:
CREATE TABLE my_table (
id INT64,
name STRING,
age INT64
);
The code above will create a table named my_table
with three columns: id
, name
, and age
. The data type for each column is specified after the column name.
You can also add additional options when creating a table. For example, you can specify the table's expiration time, its partitioning, and its clustering. Further details can be found in the Google BigQuery documentation.
For example, the following code creates a table that will expire in 7 days and is partitioned by date:
CREATE TABLE my_table (
id INT64,
name STRING,
age INT64,
date DATE
)
PARTITION BY date
EXPIRATION_TIME 7;
The code above will create a table named my_table
with four columns: id
, name
, age
, and date
. The table will be partitioned by date and will expire in 7 days.
