Mysql 将字符串与字段值合并到表中

我想在表的每个随机名称中添加一个字符串，即“Building”

我试过康卡斯特，然后+

UPDATE officine 
       SET nom = (SELECT fake_name.last_name
                               FROM fake_name
                               ORDER BY rand()
                               LIMIT 1);

我实际上：

Dupont
March

我想得到

Building Dupont
Building March

像这样的

UPDATE officine 
       SET nom = (SELECT CONCAT('Building ', fake_name.last_name)
                  FROM fake_name
                  ORDER BY rand()
                  LIMIT 1
                 );
