I want to show accounts with their highest rank character with just one Query .

output (Show Accounts with their Highest rank character)

username : player1 | 123@asd.ad | char: fgax(4)  
username : goodman | 1345@bs.ad | char: sdg2(3)  
username : goodbat | 134s@bs.ad | char: zFvx(8)  
...

My Query:

SELECT username,email,id FROM accounts

Answer 1

SELECT a.username, a.email, a.id, c.name
FROM accounts a 
JOIN chars c ON a.id = c.account 
ORDER BY a.rank DESC

Answer 2

Try this::

SELECT 
a.username as userName, 
a.email as email, 
a.id as id, 
c.name as name

FROM accounts a 
INNER JOIN chars c ON (a.id = c.accoun)t 
ORDER BY a.rank DESC

Answer 3

What you need is a table join. What table joins do is that they query 2 tables, in your case Table1 and table2. Here is the query and it will be followed by the explanation.

SELECT `t1`.`username`, `t1`.`email`, `t2`.account 
FROM `Table1` `t1`, `table2` `t2` 
WHERE `t1`.`id` = `t2`.`account` ORDER BY `rank` DESC
LIMIT 0,3

LINE 1: SELECT... t1.username means username column from t1., and so on...and the t1, t2 notation comes from...

LINE 2: FROM... Table1 t1 means I am querying from Table1, and assigned it an alias or pointer t1. This is the same for how we assign table2 to t2.

LINE 3: WHERE... This means that you join the tables based on a common column. In this case, both Table1 and table2 share the same set of values - id for Table1 and account for table2. Hence, you used the above line.

ORDER BY... This means you want to arrange the records based on a certain criteria, in this case rank. There are 2 directions - ASC which means Ascending (smallest top) or DESC which means Descending.

LINE 4: LIMIT 0,3 This means I want to get the first row (0) and only 3 records. Hence, LIMIT 0,3

This is the most comprehensive explanation I could give.

Answer 4

Try this.

SELECT 
t1.username as userName, 
t1.email as email, 
concat(t2.name, '(', t2.rank, ')') as name
FROM table1 t1 
INNER JOIN table2 t2 ON t1.id = t2.account 
ORDER BY t2.rank DESC

Answer 5

You can try this:

SELECT a.username, a.email, c.name
FROM Accounts a, characters c
WHERE a.id=c.account
ORDER BY MAX(c.rank) DESC
