将sql结果合并到一列中

Question

我有以下查询

    select tb2.customer_no, tb2.last_name, tb2.first_name
    from ccare.customer tb2
    where tb2.customer_no = '1000647'

输出

             customer_no    First name      Last name
             1000647          George              Roberts

如何将名字和姓氏组合在一列中。期望的输出将是

             customer_no       Name     
             100064        George Roberts

Answer 1

非常简单。这应该做到。

select tb2.customer_no, tb2.last_name || ' ' || tb2.first_name name
from ccare.customer tb2
where tb2.customer_no = '1000647'
