Can anyone do more simplify this query

Question

Following are ddl of two tables
1.CREATE TABLE EMPL (
     SNO NUMBER,
     ENAME VARCHAR2(25),
     JOB VARCHAR2(25),
PRIMARY KEY (SNO)
2.CREATE TABLE EMPL_DET (
     SNO NUMBER,
     SAL VARCHAR2(25)
Following are DMLs of tables
INSERT INTO EMPL(SNO, ENAME, JOB) VALUES (1, 'SMITH', 'CLERK');
INSERT INTO EMPL(SNO, ENAME, JOB) VALUES (2, 'SMITH', 'MANAGER');
INSERT INTO EMPL(SNO, ENAME, JOB) VALUES (3, 'TOM', 'CLK');
INSERT INTO EMPL_DET(SNO, SAL) VALUES (1, '1000');
INSERT INTO EMPL_DET(SNO, SAL) VALUES (2, '10000');
INSERT INTO EMPL_DET(SNO, SAL) VALUES (3, '900');
I want to calculate TotalSAL(column:empl_det.SAL) of each employee(empl.ename) with job-description(empl.job).
Means i want following rows in output
1.(JOB,TotalSAL,ENAME)-->(CLERK,11000,SMITH)
2.(JOB,TotalSAL,ENAME)-->(MANAGER,11000,SMITH)
3.(JOB,TotalSAL,ENAME)-->(CLK,900,TOM)
I tried to write down for single ename
select JOB,x.sal,ename from empl,
select sum(sal) sal from empl_det where sno in
(select sno from empl where ename ='SMITH')
)x
where ename ='SMITH'
order by ename
for each ename i have to fire this query. How can i pass ename list(SMITH,TOM) to this query?
Or can anyone do more simplify this query?

Hi,
When you put some code please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
Please read <a href="https://forums.oracle.com/forums/thread.jspa?threadID=2174552#9360002">How do I ask a question on the forums?</a>
In order to do this you can use a IN.
i.e.ename IN ('SMITH', 'TOM') etc.
However your code can be simplified as it seems redundant to me.
Please double check it and try to understand what you can improve.
Just a hint: use join and group by without subquery.
Regards.
