I'm getting error
#1222 - The used SELECT statements have a different number of columns
If I remove UNION the sql query return result but if I keep UNION the error return
I'm trying to search the number in different tables in c.title or in name from jos_user and return the result
As #danblack points out in comments, the error
#1222 - The used SELECT statements have a different number of columns
is saying that there's a different number of columns on the two SELECT statement. In
SELECT DISTINCT a.*,
categories_2625729.title AS category_title,
categories_2625729.id AS category,c.id as cid,
c.title,
'' as `introtext`,
'com_hpj_content.ad' as content_type,
'' as banner,
'' as `fulltext`,
'' as sheettext,
c.publish_up,
c.publish_down,
c.price,
c.advertiser_id,
c.seller_id,
c.sold,
c.soldupdated,0 AS is_favorite
FROM ...
..you're select a lot more columns than in this
SELECT name
FROM ...
The number of columns of those two SQL statements have to match in order for UNION to be able to add the results of the second query to the result of the first.
So this will work:
SELECT DISTINCT c.title
FROM ...
UNION
SELECT name
FROM ...
because now both individual SELECT statements return just one column.
I am new at mysql. I have code but it is displaying byte array why ?
Sorry about my english :(
SELECT p.city_id,p.name city, CONCAT("[",

it must be show json data but. The result is

MySQL Find Most Recent/Largest Record Per Group by order by, and how can i minimize / shorten this query and every time it returns the first row value of the group, whereas i like to select the last row value of a group, and sort the values based on ja.id ? I know this is a bad query can anyone suggest or provide me solution to shorten this query . I have used all the necessary Column Indexes in all the tables. How to shorten the query without the use of union all .both the queries in union all are same expect in the where statement.

It sounds like a "groupwise-max" problem. I added a tag that you should research.
At least get rid of the columns that are not relevant to the question.
Try tossing the tables other than jrtm and jr to see if the performance problem persists. (I'm thinking that the LEFT JOINs may be red herrings.)
Try with one part of the UNION, then with the other. This may identify which of the two is more of a burden.
Some indexes to add:
rja: (referby_id, create_date)
jrtm: (status, referto_email)
jrtm: (rid, status, referto_email)
jr: (referby_user_id, refer_on)
DISTINCT is not a function. Don't use parents in DISTINCT(jp.id).

Is there any way to modify this query and to make it possible to add a condition on those three aliases?
use alias in where condition .. is not allowed . because .is not possibile
the query code is evaluted based on a specified order .. starting from FROM then
WHERE clause and last the SELECT and the column alias so .. when the where is performed the column alias is not available at the query
You could try with an having condition because having work on the result of the query and not on the raw rows value .. (this could have effect on performance ..because all the query is performed and only the result is filtered by having)
