仅在数据库查询时的名字和姓氏首字母

Question

Hi can you help me in my problem?

I want to create a Profile Name which only read like this Sergio E. not this Sergio Encabo

Here is the query I have

SELECT p.id, p.title, COUNT(b.id) AS bids, p.slug, p.`description`, p.budget AS budget, p.`isFeatured`, p.`slug`, u.`profileLink`, u.`profilePhoto`, CONCAT_WS(' ', u.firstName , u.lastName ) AS fullName 
FROM tbl_projects AS p 
LEFT JOIN tbl_users AS u ON p.userId = u.userId 
LEFT JOIN tbl_bids AS b ON p.`id` = b.`projectId` 
WHERE p.`isActive` = 'y' AND u.`isActive` = 'y' AND p.`jobStatus` = 'open' AND p.userId=? 
GROUP BY p.id 
ORDER BY p.`id` DESC 

Answer 1

You could use the first char on left for lastname

but you should not use left joined tables columns in where condition this work as inner join
add these condition to on clause

    $qry = "SELECT p.id
        , p.title
        , COUNT(b.id) AS bids
        , p.slug
        , p.`description`
        , p.budget AS budget
        , p.`isFeatured`
        , p.`slug`
        , u.`profileLink`
        , u.`profilePhoto`
        , CONCAT( u.firstName ,' ', left(u.lastName,1), '.' ) AS fullName 
        FROM tbl_projects AS p 
        LEFT JOIN tbl_users AS u ON p.userId = u.userId   AND u.`isActive` = 'y' 
        LEFT JOIN tbl_bids AS b ON p.`id` = b.`projectId`
        WHERE p.`isActive` = 'y' 
        AND p.`jobStatus` = 'open' 
         AND p.userId=? 
         GROUP BY p.id 
         ORDER BY p.`id` DESC  ";
