MySQL concatenation operator

Question

I don\'t know concatenation operator for MySQL.

I have tried this code for concatenation:

SELECT vend_name || \' (\' || vend_country || \')\'
FROM Ve         


        

Answer 1

Whats good about using concat is that you can pass different data type columns and concat string representations

 SELECT concat('XXX',  10.99, 'YYY', 3, 'ZZZ', now(3)) as a; 

Output

a
