mysql - 在SELECT子句中添加/连接文本值

Question

MySQL中有没有办法使用SELECT语句将文本连接到值？(就像在Oracle中一样)

例如,在Oracle中,您可以编写如下内容:

SQL> select 'The Year is '|| year, 'The month is '|| month from time where rownum < 2;

'THEYEARIS'||YEAR
----------------------------------------------------
'THEMONTHIS'||MONTH
-----------------------------------------------------
The Year is 2009
The month is 1

Answer 1

SELECT Concat(vend_name, ' (', vend_country, ')')
FROM vendors
ORDER BY vend_name;
