I 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.

How can i retrieve which tables have composite primary keys, and only one of the primary key columns is a foreign key to another table?
Like:
CREATE TABLE club (
clubId NUMBER,
name VARCHAR(20) NOT NULL,
PRIMARY KEY (ClubId)
);
CREATE TABLE team (
teamid NUMBER(10),
clubid NUMBER(10),
teamname VARCHAR(10) NOT NULL,
PRIMARY KEY (teamid, clubid),
FOREIGN KEY (clubid) REFERENCES club (clubid));So in this case, the team table

I am trying to get information about the columns of tables in Oracle databases. In MySQL, show columns provides good deal of information.But in Oracle, we do not have such equivalent call."describe" shows only the primary key.
But it does not show whether any column has unique constraint or an index.
I created a column in a table with unique constraint (but not a primary key), but it was not listed with CONSTRAINT_TYPE = 'U' in dba_constraints view, but was listed with CONSTRAINT_TYPE = 'C' - Check constraint.

table was defined as below & indexes are also created on name /dept columns, data is also available :
create table test (
name varchar2(10),

Now the requirement is that the parition keys has to be changed to 'dept' from the existing 'version' . How to accomplish this without any implication on the indexes and other constraints.

I have employee interface table something like this.
emp_idemp_name Job_title supervisor_name
1AJ Engineer BJ
2CK Analyst ND
3BJ Manager TR
5TR VP IT JD
6ND S Manager MD
7MD VP Telecom SK
8SK VP Eng JR
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.
I am a Java person but since my app uses the Oracle DB I am to do this task.

Using the HR schema, I'm trying to write a query which will display the names and salaries of those employees who earn the highest salaries in their respective departments.
I wrote the query:
SELECT first_name, last_name, salary
FROM employees
WHERE salary =
(SELECT department_id, MAX(salary) FROM employees GROUP BY department_id);
However, this query does not execute correctly but I'm not sure why?

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?

I borrowed some code fragments from other posts and put together a sql query. I think there is a better method in other posts but I couldn't get them working.
I'm trying to get the count of hired employee(s) using the EMP table. I want from the first hire to the last and ALL in between. If there were no hires in that window, I want 0.
WITH minmax AS
(SELECT MIN(last_day(hiredate)) fmonth, MAX(last_day(hiredate)) lmonth
FROM emp),
cal AS
(SELECT add_months(fmonth, LEVEL - 1) mnth
FROM minmax
CONNECT BY LEVEL <= months_between(lmonth, fmonth) + 1),
vals AS
(SELECT extract(YEAR FROM mnth) YEAR, extract(MONTH FROM mnth) MONTH
FROM cal),
data AS
(SELECT extract(YEAR FROM hiredate) YEAR,
extract(MONTH FROM hiredate) MONTH,
COUNT(*) hired_cnt
