Setting up a primary key in Google BigQuery is fairly simple. First, you must create a table in BigQuery. To do this, you can use the CREATE TABLE
statement. For example:
CREATE TABLE my_table (
id INT64,
name STRING,
age INT64
);
Once the table is created, you can set the primary key by using the ALTER TABLE
statement. For example:
ALTER TABLE my_table ADD PRIMARY KEY (id);
The parts of the code are:
CREATE TABLE
: Used to create a new table.ALTER TABLE
: Used to modify an existing table.ADD PRIMARY KEY
: Used to set the primary key of the table.
