Question

i am working on a search system in which a person is searched by country and their firstname and the last name. For the First and Last name i used concatbut using it with further and condition doesn’t seems to work. my query is

select * from users_profile where CONCAT(fname,' ',lname) like '%v %'
or Email like '%v %' AND country='india'

in the above if ise use the query without “and” it works . but i need to specify more conditions and if i simply use and without concat that also works .

select * from users_profile where CONCAT(fname,' ',lname) like '%v %'
or Email like '%v %'

how to make it work with both concat and further and condition i want to apply.

Answer 1

You should not be using CONCAT, let alone any functions around your WHERE columns. Further, you should be specifying a column list, not SELECT *. Also check your order of criteria.

You can try something like this:

SELECT fullname, Email, country
FROM
    (SELECT CONCAT(fname, ' ', lname) AS fullname, Email, country FROM users_profile) a
WHERE (a.fullname LIKE '%v %' OR Email LIKE '%v ') AND country = 'india'
