mysql join query order by two columns

Question

I am trying to join two tables and in both tables I have 2 same column names like agent_id and date both tables have agent_id and date actually I join tables based on agent_id and now I want to order by date column but as both tables have date column so it's showing that date column twice I want it should be shown once and order by date here is an example of my tables:

Table 1 (sales_report)
date          agent_id  agent_name  agent_commission
01-Jan-2016   1         Jhon         200   
02-Jan-2016   2         Smith        250 
03-Jan-2016   3         Tracy        150
04-Jan-2016   4         Sam          120

Table 2 (payments)
date          agent_id  paid
02-Jan-2016   1         200   
03-Jan-2016   2         150 
04-Jan-2016   3         100
05-Jan-2016   4         50

I tried to join these both tables by agent_id now my question is how can I order by date ?

Here is the query I have:

SELECT *
FROM `sales_report`
INNER JOIN `payments`
ON `sales_report`.`agnt_id`=`payments`.`agnt_id` ORDER BY date

Which date do you want to order by? From sales_report or payments? — mmmm, Aug 19 '16 at 11:52
As i understand you belongs right, you should use Union instead of join. But it will be clearer if you can Show us the expected result — Jens, Aug 19 '16 at 11:53
Actually I just want to combine the results and order by date of both tables for example if table 1 date value is '01-Jan-2016' and table 2 date value is '02-Jan-2016' so system should print first table values and then values from 2nd table this was all the records will be appear — SimulationCode, Aug 19 '16 at 11:58

I just want to combine the records of two tables and order by date of each table. — SimulationCode, Aug 19 '16 at 12:12
Actually union is the answer of my question but I can't use union because both tables have some different columns and I want to select all not only specific columns records — SimulationCode, Aug 19 '16 at 12:20

    SELECT sr.*,pm.paid
    FROM `sales_report` as sr
    INNER JOIN `payments` as pm
    ON sr.`agent_id`=pm.`agent_id` 
    ORDER BY sr.date, pm.date

Will get you date from first table and order by 1st table date then 2nd table date.

2nd table result show appear bellow the first table's row. I don't want all columns of each tables into one row – SimulationCode Aug 19 '16 at 12:13
In other words I just want to combine both tables and show them older first and newest after – SimulationCode Aug 19 '16 at 12:14

    SELECT * FROM
    (
         SELECT sr.date
            FROM `sales_report` as sr
         UNION
         SELECT pm.date
            FROM `payments` as pm
        )
    ORDER BY date

I think this is what you wanted,Both sales_report and payments need be considered as a table.then sort it.
