assigning values to a particular variable that i need for my button trigger. I Understand that you can assign multiple values to a variable that has a varchar or char data type....is there a way to assign multiple values to a variable that has a 'number' data type?? I need this for my 'where' clause
declare usergrade varchar(4) := 'pass'; user_unitcode number(6) := ;--needs three unit codes to equal pass

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 [code]...
I 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
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?
I want TO find out FIRST two employee joined IN A particular department WITH department information.THE relation IS basically FROM THE scott SCHEMA.I tried LIKE AS follows. IS there ANY other way FOR best PERFORMANCE.
SELECT deptno,dname,loc, Max(Decode(rn, 1, hiredate))hiredate1, Max(Decode(rn, 1, ename)) employee1, Max(Decode(rn, 2, hiredate))hiredate2, Max(Decode(rn, 2, ename)) employee2 FROM (SELECT d.deptno,dname,loc,hiredate,ename,Row_number() over(PARTITION BY e.deptno ORDER BY hiredate) rn FROM dept d, emp e WHERE d.deptno = e.deptno(+)) GROUP BY deptno,dname,loc;
I 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. .
I want to update the names of employees by concatenating with A for DEPT 20. For that I have written the following PL/SQL block. But instead of one A the ename are concatenating with five AAAAA s.
DECLARE TYPE lt_emp_arr IS TABLE OF t_emp.deptno%TYPE; l_emp_arr lt_emp_arr; BEGIN SELECT deptno BULK COLLECT INTO l_emp_arr [code].......

I WANT to RETRIEVE all the INFORMATION of DEPT ALONG with TWO EMPLOYEES of each DEPARTMENT.is any OTHER WAY to DO THIS due to performance in Oracle 10g
I had as source a set of actions where I have to assign the end date, the general rule is that each action has the same end date to start date of next action, if there is no next action it will be assigned the default('35001230').
I can do the assignment with the date of order:
NVL (LAG (DAT_INI) OVER (PARTITION BY ID_CLIENT DAT_INI ORDER BY DESC, DESCCOD_SEVERITY), TO_DATE ('35001230 ',' YYYYMMDD ')),
However, I have an exception to the rule, if the action have COD_SEVERITY = 3 or 4 and the next action have the COD_SEVERITY = 3 or 4, the end date will be for the previous day. If in the same day I have actions with COD_SEVERITY 3 and 4, the end date of actions with COD_SEVERITY = 3 will be DAT_INI -1 and the action with COD_SEVERITY = 4 will have the same date of the next action or DAT_INI -1 if the next action had COD_SEVERITY = 3 or 4
The source SELECT 1 as ID_CLIENT, 20111201 as DAT_INI, 1 as COD_SEVERITY, 100 as VALUE FROM DUAL UNION ALL SELECT 1 as ID_CLIENT, 20111201 as DAT_INI, 3 as COD_SEVERITY, 100 as VALUE FROM DUAL UNION ALL SELECT 1 as ID_CLIENT, 20111204 as DAT_INI, 4 as COD_SEVERITY, 101 as VALUE FROM DUAL UNION ALL [code].......
begin declare tmdate DATE; select TO_DATE(TO_CHAR(MAX(DATERANGE),'DD-MON-YYYY')) into tmdate from table_check_date_range; dbms_output.put_line(tmdate); end;
