SQL & PL/SQL :: How To Find Minimum Salary Holders
Nov 7, 2012
in this query, i am stuck in this little query but cant get answer lets suppose
select * from emp;
EMPNO ENAME JOB SAL
---------------------- ---------- --------- ----------------------
7788 SCOTT ANALYST 3000
7902 FORD ANALYST 3000
7876 ADAMS CLERK 1100
7934 MILLER CLERK 1300
7900 JAMES CLERK 950
[Code]....
now if i want to see min salary takers group by job then i use
select x.job, min(x.sal), count(*) from emp x group by x.job;
JOB MIN(X.SAL) COUNT(*)
--------- ---------------------- ----------------------
CLERK1 800 1
SALESMAN 1000 5
CLERK 950 3
PRESIDENT 5000 1
MANAGER 2450 5
Developer 2975 1
ANALYST 3000 2
The above result give me minimum salary but total number of JOB holders, You can see only one SALEMAN getting 1000 but count show total number of SALESMAN. Similarly 3 MANAGERS are getting minimum and same salary but count show total number of MANAGERS.
My question is how can i get number of person on min salary?
Possibly my data should be like as this
JOB MIN(X.SAL) COUNT(*)
--------- ---------------------- ----------------------
CLERK1 800 1
SALESMAN 1000 1
CLERK 950 1
PRESIDENT 5000 1
MANAGER 2450 3
Developer 2975 1
ANALYST 3000 2

I have a table structure as follows Student(Id,First_Name, Last_Name, email, Contact, Address1 ,Address2, City, Edit_Date,Create_Date,Archived)
Now if there is more than one row with same email the one with the latest edit date should be updated with missing fields by using same field value other rows (if the field is present in more than one row, the one with the next latest edit date is to be considered) and
the archived status of all rows with same email except this master row must be set to 1.The Create_Date must be set to the minimum of all the create_date values of rows with same email value

SELECT
REF.REFERRAL_TO,
REF.LOCAL_PATIENT_NUM,
REF.REFERRAL_REFERENCE_NUM,
TO_CHAR (REF.REFERRAL_DTE, 'DD/MM/YYYY') REFDATE,
TO_CHAR (OPC.CONTACT_DATE, 'DD/MM/YYYY') CONTACTDATE,
TO_DATE (OPC.CONTACT_DATE, 'DD/MM/YYYY') - TO_DATE (REF.REFERRAL_DTE, 'DD/MM/YYYY')
FROM
PAS.REFERRAL_DETAILS REF
FULL JOIN
PAS.OUTPATIENT_CONTACT OPC
[Code]...
This calculates the difference between a set date and a contact date, I only want it to return the minimum of the results set for each patient, how can this be achieved? At the moment it pulls off several records for each patient as there are several contacts.

I have the following case:
create table try_o
(pk1 NUMBER, pk2 NUMBER, fld1 VARCHAR2(10), fld2 NUMBER,
PRIMARY KEY (pk1, pk2));
insert ALL
into try_o values (1,1,'f1',5)
into try_o values (1,2,'f1',5)
[Code]....
I need to get the row that contains the least pk2 among the group of records with the same fld1 and fld2. but if I used
select min(pk1), min(pk2), fld1, fld2
from TRY_o
group by fld1, fld2;
I get a record that doesn't exists as the min(pk1) and min(pk2) are from different records. I need to get the min(pk1) and its corresponding pk2.

i am trying to enable flashback on in my database and i am getting the below error.
idle> alter database flashback on;
alter database flashback on
*
ERROR at line 1:
ORA-38706: Cannot turn on FLASHBACK DATABASE logging.
ORA-38708: not enough space for first flashback database log file
my db_recovery_file_dest_size is 1g. If i change it to 20g i am able to "alter database flashback on".
Why does a size of 1g give this proble? Any simple steps or recommendation that i am missing? Or is the size of the DB which impacts the db_recovery_file_dest_size also?
idle> select *from v$version;

I am trying write a script that will return all values (based on the minimum tarif) from the Germany table for any duplicate values. Duplicate values are any values with the same UFI, ZC,limitid,depot. The German table also contains the fields tarif, city, supplier, etc.
Below is the script I have previously used to sort out duplicates. I have tried 50 different ways get it to return just lines for the minimum tariff but haven't been successful.
select *
from Germany t
where (ufi,zc,limitid,depot) in (
select ufi,zc,limitid,depot from (
select ufi,zc,limitid,depot, count(*) n
from Germany t
group by ufi,zc,limitid,depot)
where n<>1
)

I have following data
select rowid,object_name,object_type from do;
ROWID OBJECT_NAME OBJECT_TYPE
------------------ ------------------------------ ------------------
AAA/wuAAHAAAW73AAA CON$ TABLE
AAA/wuAAHAAAW73AAB I_COL2 INDEX
AAA/wuAAHAAAW73AAC I_USER# INDEX
AAA/wuAAHAAAW73AAD C_TS# CLUSTER
AAA/wuAAHAAAW73AAE I_OBJ# INDEX
AAA/wuAAHAAAW73AAF I_CON2 INDEX
6 rows selected.
I want it in the following manner
select rowid,object_name,object_type from do;
ROWID OBJECT_NAME OBJECT_TYPEGROUP
------------------ ------------------------------ ---------------------------
AAA/wuAAHAAAW73AAA CON$ TABLE2
AAA/wuAAHAAAW73AAB I_COL2 INDEX1
AAA/wuAAHAAAW73AAC I_USER# INDEX1
AAA/wuAAHAAAW73AAD C_TS# CLUSTER1
AAA/wuAAHAAAW73AAE I_OBJ# INDEX1
AAA/wuAAHAAAW73AAF I_CON2 INDEX1
6 rows selected.
Here the GROUP is changing when the data type is changing and thus for same data type the group shall remain the same As of now this is achieved by - first selecting distinct object_type, then it's mod(rownum,<input variable) and this result of 'mod' is doing the grouping which is the retrieved along with rowid of all individual record
Present query is as following and it is not much efficient
SELECT DO.ROWID RWID, RID
FROM DO,
(
SELECT OT,CASE MOD(ROWNUM,:v) WHEN 0 THEN :v ELSE MOD(ROWNUM,:v) end as RID
FROM(
(SELECT DISTINCT OBJECT_TYPE OT
[code]....
I tried using sequence with cycle but it gave different results. Even I tried following but it did not gave satisfactory results
select d.rowid,d.object_type,x.x1 from do d,(select distinct object_type,mod(rownum,:v) x1 from do where
created>'01-jan-2008')x where d.object_type=x.object_type and created>'01-jan-2008';
In short the query needs Distinct with mod(rownum) and individual records in a single pass The mod(rownum) i.e. group shall change when the object_type changes but then shall remain constant through out the particular object_type.

A.Create object to get the salary hike of an employee on the basis of completion of years in an organization.
Conditions:-
Create two tables with name as "Employee_yourname" and "Employee_Hike_Yourname".
"Employee_yourname" can have columns like EMPID, NAME, SALARY, DATE_OF_JOIN.
"Employee_Hike_Yourname" will have 3 more columns for new salary, Current salary and completed period in organization.
Consider the employees who have completed minimum one year in organization.
Salary hike for employee with tenure >= 1yr and < 2yrs should be 10% of current salary.
If tenure is greater than or equal to two years and less than 3 years then salary hike should be 20% of current salary.
For employees having tenure more than 3 years hike should be 30% % of current salary

I want to display the maximum sum of salary among sum of salary of each department.
deptno sal
10 1000
10 500
10 100
20 2000
20 200
30 500
30 1500
30 2000
30 200
Sum of salary for each department.
10 1600
20 2200
30 4200
The output should be
30 4200
Because this the highest sum of salary compare to sum of salary of reaming departments.

I am trying to restore to a backup instance on a backup server. When I try to recreate the tables I keep getting ORA-01659: unable to allocate MINEXTENTS. The tablespaces and datafiles on both servers show as the same size in OEM.
I have dropped all tables and OEM shows tablespaces are empty. Then I run a script to recreate all tables. Most of the tables don't get created because their TS is full. After the script to recreate all tables runs, the main tablespaces are full, more full than on the production machine. I have also tried ALTER TABLESPACE xxx COALESCE; on each tablespace right after dropping all tables and before recreating them to reclaim free space. Why is it full? I've only dropped and created the tables, there shouldn't be any data in them yet.
ORA-01659: unable to allocate MINEXTENTS beyond 2 in tablespace PLUS_T...The backup instance was already there, all I did was drop the tables. Here's what I ran on prod to build a script to recreate the tables on backup server. Got it off Burleson somewhere.
SELECT DBMS_METADATA.GET_DDL('TABLE',u.table_name) ||'; '
FROM USER_TABLES u;

what is the Minimum datafile size required for creating a non-system tablespace?
I am trying to create a tablespace by giving the syntax like,
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 72k;
create tablespace t1
*
ERROR at line 1:
ORA-03214: File Size specified is smaller than minimum required
SQL> create tablespace t1
2 datafile '/home/data/t1.dbf' size 73k;
Tablespace created.
The blocksize for my database is 4096, as i have heard that the minimum size of the datafile is decided by blocksize, but i want to know that how it is calculated as by giving the above syntax the other values will be default. I am trying the syntax in oracle 9.2.0.1.0 version.
