You are working with Azure Synapse Analytics and need to transform data using Transact-SQL (T-SQL). You have a table with customer information, including customer_id, first_name, last_name, and email_address. You need to create a new table that contains only the customer_id and full_name columns, where full_name is a concatenation of first_name and last_name. Which T-SQL query would you use to achieve this?_
A
SELECT customer_id, CONCAT(first_name, last_name) AS full_name FROM customer_table_
B
SELECT customer_id, first_name + ' ' + last_name AS full_name FROM customer_table_
C
SELECT customer_id, STRING_AGG(first_name, last_name, ' ') AS full_name FROM customer_table
D
SELECT customer_id, first_name || ' ' || last_name AS full_name FROM customer_table_
