I have three tables in my db.
Table A
has the fields
KEYID | KeyName
27 | Income
28 | Account Number
Table B
has the fields
UserID | Email | Name | Phone
481 | test@gmail.com | test | 99999999
Table C
has the fields
ID | KEYID | UserID | Value
1 | 27 | 481 | 10,000
I need to display the table fields headers are:
UserID | Email | Name | Phone | Income
and the table values should be like this:
481 | test@gmail.com | test | 99999999 | 10,000
I can get the KeyIDs which should be displayed in the table. In this example the KeyIDs string is '27' . I tried with joining and i can fetch & display the value in the table. but i dont know how i can show the key name as table header.
Any Idea.?
You can use a pair of inner join
select b.UserID, b.Email , b.Name, c.value as income
from tableB as b inner join tableC as C on b.userID = c.userId
inner join tableA as a on a.keyID = c.keyID
and a.keyname = 'Income';
and the query you provided in comment
select
b.UserID
, b.Email
, b.Name
, Group_Concat(Distinct Concat(c.keyID,’^:^’,c.value)
Order By c.id Separator ‘;’) As Keyvalues
from tableB as b
inner join tableC as C on b.userID = c.userId
inner join tableA as a on a.keyID = c.keyID;
and with CASE should be
select
b.UserID
, b.Email
, b.Name
, Group_Concat(Distinct CASE
WHEN c.keyID IN ('1,23,10') THEN Concat(c.keyID,’^:^’,c.value) END
Order By c.id Separator ‘;’) As Keyvalues
from tableB as b
inner join tableC as C on b.userID = c.userId
inner join tableA as a on a.keyID = c.keyID;
This query should help to get your desire result.
select b.UserID, b.Email, b.Name, b.Phone, c.Value as Income
from table_b as b
JOIN table_c as c ON (b.UserID = c.UserID)
where c.KEYID = 27
Try this:
SELECT b.userid, b.email, b.name, b.phone, c.value as income
FROM a
LEFT JOIN c on c.keyid = a.keyid
LEFT JOIN b ob b.userid = c.userid
