SUM query's result which contain UNION ALL and CTE - sql

Question

Even though I found something similar to what I was needed, I wasn't able to work it out.
So, I'll ask using my example.
(It is in continuation to my prev question: select if there are more than n results but with conditions)
My Table:
| TimeId | Work_Role | User_Name |
----------------------------------
| 1 | users | Oran |
| 2 | admin | Ray |
| 3 | users | Oran |
| 4 | servs | Amit |
| 5 | admin | Oran |
| 6 | users | Ray |
| 7 | users | Oran |
| 8 | servs | Amit |
| 9 | admin | Oran |
| 10 | users | Oran |
I've used CTE to display a list for user_name = "Oran" and Work_Role = "users" ONLY if there are more than 2 in the table.
In addition, I used Union all to gather another part that it's condition is: user_name = "Oran" and Work_Role = "admin".
The result is:
| TimeId | Work_Role | User_Name |
----------------------------------
| 1 | users | Oran |
| 3 | users | Oran |
| 7 | users | Oran |
| 10 | users | Oran |
| 5 | admin | Oran |
| 9 | admin | Oran |
My second part (which there I have the problem) is to count how many lines the result above has.
In this case I expect: 6
My code for the first result (which is working fine):
WITH CTE AS(
SELECT *, cc = COUNT(*) OVER(PARTITION BY User_Name) FROM Table
)
SELECT *
FROM CTE
WHERE
Work_Role = 'users'
AND User_Name = 'Oran'
AND cc > 2
UNION ALL
SELECT *
FROM TABLE
WHERE
Work_Role = 'admin'
AND User_Name = 'Oran'
How can I summarize the lines' number of the final result?
Can it even be done while using CTE?
NOTE:
This is just an example. In my real code I must use the "UNION ALL" :-(
10X!

Answer 1

First, you can simplify the query to:
WITH CTE AS (
SELECT t.*, cc = COUNT(*) OVER(PARTITION BY User_Name) FROM Table t
)
SELECT *
FROM CTE
WHERE (Work_Role = 'users' AND User_Name = 'Oran' AND cc > 2) OR
(Work_Role = 'admin' AND User_Name = 'Oran');
The nice thing is that this will also work, because the two subqueries have the same columns.
If you want to count the number of rows, just use select count(*):
WITH CTE AS (
SELECT t.*, cc = COUNT(*) OVER(PARTITION BY User_Name) FROM Table t
)
SELECT COUNT(*)
FROM CTE
WHERE (Work_Role = 'users' AND User_Name = 'Oran' AND cc > 2) OR
(Work_Role = 'admin' AND User_Name = 'Oran');

Answer 2

Ok, eventually I've found an answer, lol
It is based on the first answer of this question: Sum a union query
I had to alias my derived table.
Set the additional select (with the SUM) between the "THIS" and it's "SELECT".
Change to COUNT for each query and alias it.
Like so:
WITH CTE AS(
SELECT *, cc = COUNT(*) OVER(PARTITION BY User_Name) FROM Table
)
SELECT SUM(my_dervied_table.total_lines) FROM (
SELECT COUNT(*) as 'total_lines'
FROM CTE
WHERE
Work_Role = 'users'
AND User_Name = 'Oran'
AND cc > 2
UNION ALL
SELECT COUNT(*) as 'total_lines'
FROM TABLE
WHERE
Work_Role = 'admin'
AND User_Name = 'Oran'
) my_dervied_table
So instead of counting the lines in this output:
| TimeId | Work_Role | User_Name |
----------------------------------
| 1 | users | Oran |
| 3 | users | Oran |
| 7 | users | Oran |
| 10 | users | Oran |
| 5 | admin | Oran |
| 9 | admin | Oran |
I'm actually summing the 'total_lines' column's content of the "my_derived_table": 4+2 = 6
| total_lines |
---------------
1) | 4 |
2) | 2 |

shalom yael-try this code-
WITH CTE AS
(
SELECT *
FROM tbl
WHERE
Work_Role = 'users'
AND User_Name = 'Oran'
AND ( select COUNT(user_name)
FROM tbl
WHERE user_name='oran') > 2
UNION ALL
SELECT *
FROM tbl
WHERE
Work_Role = 'admin'
AND User_Name = 'Oran')
SELECT count([User_Name]) total_lines
from cte
GROUP BY [Work_Role],[User_Name]

Answer 4

Are you looking for this,
Declare #t table(TimeId int,Work_Role varchar(50),User_Names varchar(50))
insert into #t values
(1 , 'users','Oran' ),
( 2 ,'admin', 'Ray'),
( 3 ,'users', 'Oran'),
( 4,'servs', 'Amit'),
( 5,'admin', 'Oran'),
( 6,'users', 'Ray'),
( 7,'users', 'Oran'),
( 8,'servs', 'Amit'),
( 9,'admin', 'Oran'),
( 10,'users', 'Oran')
;With CTE as
(
select *,
ROW_NUMBER()over(partition by User_Names,Work_Role order by timeid)rn
from #t
)
select * from CTE where Work_Role = 'users'
AND User_Names = 'Oran'
AND exists
(
select User_Names from CTE where rn>2
and Work_Role = 'users' AND User_Names = 'Oran'
)
UNION ALL
select * from CTE where Work_Role = 'admin'
AND User_Names = 'Oran'
