Question

Consider the following table:

id  foo
-----------
1   bar
2   baz
3   bat

Desired output (from SQL query):

id str_id foo
--------------
1  str1   bar
2  str2   baz
3  str3   bat

In this case, “str” is concatenated to every id. Is this possible and if so how, in MySQL?

Answer 1

SELECT `id`, CONCAT('str', `id`) AS `str_id`, `foo`
FROM `tbl`
ORDER BY `id` ASC;
