PL/SQL :: Count Number Of Employees In Every Department - Group By Clause Not Working
Oct 31, 2012I have two columns Department and EmpName:
Department EmpName
____________________________________
Sales empname1
Sales empname2
Marketing empname3
Development empname4
Now I want to count the number of employees in every department. I want the output to be
Department Total
______________________
Sales 2
Marketing 1
Development 1
I am retrieving names of the department through a subquery
The query I am trying to execute is:
SELECT Department, Employee FROM
( SELECT ...query from other table) AS Department, count( A.EmpName) AS Employee
FROM Employer A, EmployeeInfo B
WHERE (A.EmpID = B.EmpID AND A.EmpCategory like 'Category2')
GROUP BY Department
I know that you cannot group by using aliases and hence a little work around, but still the query isn't working.
Performance Tuning :: Create Statements On A Highly Fragmented Disk
Nov 24, 2010On Oracle 10g, I create, delete and drop a lot of tables. Therefore, the disk is highly fragmented.The execution of a very simple create statement takes more than a minute. If I execute the same statement but first truncate the table and insert the data, it takes less than a second!
I think this has to do with the high fragmentation of the disk. Obviously, I can defragment the disk, but I will always have a high fragmentation since I use a lot of create, delete and drops.
how I can improve the performance of create statements on highly fragmented disks?

I want to idenitfy the VP for each employee. The logic I have to apply is check for hte supervisor of each employee to see if the supervisor has designation starting with 'VP'. If no, I have check the supervisor of the supervisor and so on. I tried using a recursive query using connect_by_root but in the above example for employee ND it lists the VP as both MD and SK. I need it to show on MD who is the lower in the hierarchy.

SQL & PL/SQL :: How To Get All Employees Under Same Manager
Sep 27, 2010For table employees with
EMPLOYEES
__________________________________________
EMPID NAME MANAGERID
------------------------------------------
34 Amy
17 Ben 34
5 Chris 34
10 Don 5
...
How can we use SQL to get all employees under one manager , either direct or indirect
I only can think the following SQL to get the first direct employee.
select e1.empid
from employees e1, employees e2
where e1.managerid = e2.empid
and e2.empid = '34';
Perhaps we could put it in PL/SQL procedure to do recursive call?

SQL & PL/SQL :: Update Job-id Of Employees Table Of HR Schema?
Jan 8, 2012I am trying to update of job_id column of employees table for employee number 205 two times one after another. First time job_id column of employees table for employee number 205 is updated with new job_id. But second time job_id column of employees for employee number 205 table can not be updated. Oracle returns the following errors
HR:orcl > update employees set JOB_ID='AC_MGR' where employee_id=205;
update employees set JOB_ID='AC_MGR' where employee_id=205
*
ERROR at line 1:
ORA-00001: unique constraint (HR.JHIST_EMP_ID_ST_DATE_PK) violated
ORA-06512: at "HR.ADD_JOB_HISTORY", line 10
ORA-06512: at "HR.UPDATE_JOB_HISTORY", line 2
ORA-04088: error during execution of trigger 'HR.UPDATE_JOB_HISTORY'
As there is composite primary key using employee_id and start_date column.how to update same employee job_id twice.AS we can see from job_history table, the record for employee 200 is as follow
EMPLOYEE_ID START_DATE END_DATE JOB_ID DEPARTMENT_ID
----------- ----------- ---------- ---------- -------------
200 17-SEP-1987 17-JUN-1993 AD_ASST 90
200 01-JUL-1994 31-DEC-1998 AC_ACCOUNT 90
So how can i do the same for employee 205 without changing hire_date after first job_id update. Since for every update of job_id fires trigger. To insert row in job_history table employee id and start_date must be unique each time. HERE hire_date of employees table is used as start_date of job_id table. how it was possible for employee id 200 to change job_id twice?

View 2 Replies View RelatedSQL & PL/SQL :: Display Count Of Employees That Belongs To Different Categories?
Sep 21, 2010I have to display count of employees that belongs to different categories.
is the situatio There is a category table CATEGORY with three columns (PK,NAME,TREEPOSITION) and we have categories A, B, C these three categories can further have sub-categories so the treeposition for the sub categories will be followed by their root category with _ 'symbol'
Now I have table for the employees with 3 columns (pk,name,category_id), where employees.category_id=category.pk So I want to calculate the number of employees in each category or sub-category.
since the number of categories will be large and each will be having different names so going through names will be bad option left is grouping through the treepostion
the problem is I cant use like using IN for the TREEPOSITION. .
TABLE EMPLOYEES ( PK,NAME,CATEGORY_ID)
TBALE CATEGORIES (PK,NAME,TREEPOSITION)
