list values ​that are duplicated more than 4 times - sql

Question

I am making a join between 2 tables, where they bring me number_phone that have a relationship and I bring the times that these are repeated, however, I am trying to make a condition to the count, so that it only lists those that are repeated more than 4 times, I tried with having account and it brings me the counter all in null.
It is worth mentioning that I did not occupy group by for the count because it brought me wrong values.
SELECT
REPLACE(REPLACE(t.id_contrato,'0999',''),'0998','')as contrato ,
t.num_telefono,
conc.valor_actual,
(
SELECT COUNT('x')
FROM TBL_TELEFONO ct
WHERE ct.num_telefono = t.num_telefono
AND ct.origen_tel='TELEFONO CONTRATO'
-- HAVING COUNT(*) > 4
) as counter
FROM TBL_TELEFONO t
INNER JOIN CAM_TBL_ALERTA_CONCENTRADO conc ON t.num_telefono = conc.valor_actual
WHERE id_contrato IS NOT NULL
AND id_contrato NOT IN ('N/A')
ORDER BY 4 DESC
How can I list only those that are repeated more than 4 times?

Answer 1

I don't like debugging code with no sample data, so I'll try to illustrate it on Scott's sample EMP table. "Jobs" will act like your "telephone numbers".
SQL> select deptno, ename, job
2 from emp
3 order by job;
DEPTNO ENAME JOB
---------- ---------- ---------
20 SCOTT ANALYST --> 2 analysts
20 FORD ANALYST
10 MILLER CLERK --> 4 clerks
30 JAMES CLERK
20 SMITH CLERK
20 ADAMS CLERK
30 BLAKE MANAGER --> 3 managers
20 JONES MANAGER
10 CLARK MANAGER
10 KING PRESIDENT --> 1 president
30 TURNER SALESMAN --> 4 salesmen
30 MARTIN SALESMAN
30 WARD SALESMAN
30 ALLEN SALESMAN
14 rows selected.
SQL>
According to that, we'd like to fetch all clerks and salesmen as there are 4 (or more) of them.
Instead of count aggregate function, use count in its analytic form:
SQL> select deptno, ename, job,
2 count(*) over (partition by job) cnt
3 from emp
4 order by job;
DEPTNO ENAME JOB CNT
---------- ---------- --------- ----------
20 SCOTT ANALYST 2
20 FORD ANALYST 2
10 MILLER CLERK 4
30 JAMES CLERK 4
20 SMITH CLERK 4
20 ADAMS CLERK 4
30 BLAKE MANAGER 3
20 JONES MANAGER 3
10 CLARK MANAGER 3
10 KING PRESIDENT 1
30 TURNER SALESMAN 4
30 MARTIN SALESMAN 4
30 WARD SALESMAN 4
30 ALLEN SALESMAN 4
14 rows selected.
SQL>
Now things become easier: use that query as a CTE (or a subquery), and apply where clause:
SQL> with temp as
2 (select deptno, ename, job,
3 count(*) over (partition by job) cnt
4 from emp
5 )
6 select deptno, ename, job
7 from temp
8 where cnt >= 4
9 order by job;
DEPTNO ENAME JOB
---------- ---------- ---------
10 MILLER CLERK
30 JAMES CLERK
20 SMITH CLERK
20 ADAMS CLERK
30 TURNER SALESMAN
30 MARTIN SALESMAN
30 WARD SALESMAN
30 ALLEN SALESMAN
8 rows selected.
SQL>
Applied to your query (again, can't test it without any sample data):
with temp as
(select
replace(replace(t.id_contrato,'0999',''),'0998','')as contrato ,
t.num_telefono,
conc.valor_actual,
count(*) over (partition by t.num_telefono) as counter
from tbl_telefono t
inner join cam_tbl_alerta_concentrado conc on t.num_telefono = conc.valor_actual
where id_contrato is not null
and id_contrato not in ('N/A')
)
select contrato, num_telefono, valor_actual
from temp
where counter >= 4;

Answer 2

Join to the selection that have more than 4
SELECT
REPLACE(REPLACE(t.id_contrato,'0999',''),'0998','')as contrato ,
t.num_telefono,
conc.valor_actual,
ct.counter
FROM TBL_TELEFONO t
INNER JOIN (
SELECT num_telefono, COUNT(*) AS counter
FROM TBL_TELEFONO
WHERE origen_tel='TELEFONO CONTRATO'
GROUP BY num_telefono
HAVING COUNT(*) > 4
) ct
ON ct.num_telefono = t.num_telefono
INNER JOIN CAM_TBL_ALERTA_CONCENTRADO conc
ON t.num_telefono = conc.valor_actual
WHERE id_contrato IS NOT NULL
AND id_contrato NOT IN ('N/A')
ORDER BY ct.counter DESC

Answer 3

Wrap the query in another to return only where count > 4
select *
from (
<your query, but without order by>
) x
where count > 4
order by count desc
