Sql query inner join with LIKE and WHERE

Question

I have 2 tables. One called tbl_issue one called tbl_user . tbl_issue has a field called issue list that contains issues column such as id , uid (user id), pid (project id) etc. tbl_user on the other hand has a table it holds user details like id (that is user id), u_name (that is user name), p_list (projects id) etc.

I want to show user name according to uid (user id) code is:

SELECT tbl_issue.id, tbl_issue.pid, tbl_issue.uid, tbl_user.u_name 
FROM tbl_issue 
INNER JOIN tbl_user ON tbl_issue.uid LIKE Concat('%',tbl_user.id,'%')
WHERE uid = $uid;

code example:

SELECT tbl_issue.id, tbl_issue.pid, tbl_issue.uid, tbl_user.u_name
FROM tbl_issue 
INNER JOIN tbl_user ON tbl_issue.uid LIKE '%7%'
WHERE uid = '7'`

here uid=7 and tbl_user.id =7 is Lokesh Sharma

this code is given output

id  pid  uid  u_name
14  4    7    admin
14  4    7    ramesh
14  4    7    hemant
14  4    7    lokesh
17  3    7    ravi
17  3    7    lokesh

I want to result like

14  4    7    lokesh
15  4    7    lokesh
16  5    7    lokesh
17  5    7    lokesh
18  3    7    lokesh
19  3    7    lokesh

please help and suggest right way

Answer 1

You are trying to join tbl_user to tbl_issue using LIKE . What is wrong with just tbl_issue.uid = tbl_user.id ?

And your ON condition is pointed on a value, which is either a variable or 7, instead of the column of tbl_user .

SELECT a.id, a.pid, b.id, b.u_name
    FROM tbl_issue a
    LEFT JOIN tbl_user b ON a.uid = b.id
    WHERE b.id = 7
