sqldatatypes – Alternative to Postgresql BIGSERIAL data type in Azure Database?

I am learning Azure and data analytics with Azure. Recently finished learning Postgresql.

My question is if there is an alternative to BIGSERIAL data type for Azure Databases. I ran the query (below the error in the following) and had an error. Note that this datatype exists in Postgresql and hence I am getting confused in Azure. Any alternative to BIGSERIAL?

Failed to execute the query. Error: Column, parameter, or variable #1:
Cannot find data type BIGSERIAL.

create table person (
    first_name VARCHAR(50) NOT NULL,
    last_name VARCHAR(50) NOT NULL,
    email VARCHAR(50),
    gender VARCHAR(50) NOT NULL,
    date_of_birth DATE NOT NULL,
    Country_of_birth VARCHAR(50) NOT NULL
