How to use alias in where clause in mysql

Question

Are there any other way of doing this query:

SELECT CONCAT_WS(\" \", strLname, strFname, strMname) AS lessor_name 
FROM tbl_lessor 
WHERE lessor = \'$less         


        

Answer 1

It might be due to lessor instead of lessor_name in where clause. So try with below once :

SELECT CONCAT_WS(" ", strLname, strFname, strMname) AS lessor_name 
FROM tbl_lessor 
having lessor_name= '$lessor_name'
