select field1,field2,field3 from table2
In the query from table2 i am getting duplicate rows, HOW can i retrieve only distinct rows...Using distinct keyword did not work...if i have to post create and insert statements for this one...
I've read so many different pages on this topic but I can't seem to get my query the way it needs to be. Here's the query:
select admitnbr, lastname||', '||firstname||' '||finitial, hphone, mobile, wphone, med_rec, dob from patients join schedule using (key_patien) join adtmirro using (key_patien) where appt_state = 'ON HOLD'
Because patients in my database can have multiple appointments "on hold" there are duplicates in the results. I only need 1 record per patient in order to forward this information into an automated dialer to contact that patient. I do NOT want to call the patient over and over again. Once will suffice. I'm trying to make a distinction on the column 'med_rec'. One row per 'med_rec' will be awesome but I can't find a way to create a distinct on that column.
select distinct c.process_id a.role_id,a.email_address,c.process_name from role a, notification_role b, process c where a.role_id=b.role_id and b.process_id = c.process_id
I have had a google around and can't seem to find an answer as to how do do the following Select statement. i am wanting to Select the following fields from across multiple tables.
My task is to test a field in a certain database. We shall refer to the field as ship_to. There is an algorithm for which the field ship_to is populated and higher up in the algorithm, a variable we shall call X is created. The algorith states that I should assign the variable to ship_to unless X is = -1. If X is = -1, the algorithm continues with multiple joins and assignments. What would be the best way to go about coding this solution. There are 4 individual paths. I have only described the first path, but they are similiar in structure. I was thinking of using either Case's or decodes?The field ship_to is a number. I have already created a statement to test the sum of the Target, but now I need to test the entire algorithm to see if it too sums the Target.
insert into TEST (ENT_SIG, EMP_ID, DATE_START, DATE_END) values ('014', '120', TO_DATE('20080101','YYYYMMDD'), TO_DATE('20080131','YYYYMMDD')); insert into TEST (ENT_SIG, EMP_ID, DATE_START, DATE_END) values ('014', '121', TO_DATE('20080201','YYYYMMDD'), TO_DATE('20080228','YYYYMMDD')); [code].....
I'm asking if there's a way to do this:
update test a set (date_Start, date_end) = (select date_start, date_end from test2 b where b.emp_id = a.emp_id [code].......
Without using the WHERE EXISTS. I don't want to make two accesses to table2, I would like instead to do something like "If subquery returns a row, use it, else keep what you have in destination table".
Is there a way to do it without entering test2 twice?
Note: The ... in the tables are just placements symbolizing that there are multiple irrelevant (to this thread) fields.
The problem is with the field highlighted in italics whilst the primary keys are in bold. I need to somehow retrieve that ID, but I can't create a many-to-many relationship.
I need to take the distinct values from VARRAY.. I have wrote following simple example. But it does not work. how to get the distinct value from VARRAY.
declare type t is varray(10) of varchar2(10); t1 t; type r is table of varchar2(10) index by binary_integer; r1 r; begin t1 := t('A','B','A','B','A','B','C'); select distinct * into r1 from table(select * from t1); END;
I have following query which gives currency code from two different tables. I would like to get the distinct count of currency codes from these two different columns.
SELECT eb.person_seq_id, eb.bonus_amount, eb.currency_cd, ed.currency_cd_host FROM fr_emp_bonuses eb, fr_emp_details ed, fr_periods p WHERE eb.person_seq_id = ed.person_seq_id AND ed.period_seq_id = eb.period_seq_id AND ed.period_seq_id = p.period_seq_id AND p.period_status = 'CURRENT' AND eb.bonus_amount >= 0 AND eb.person_seq_id = 3525125;
I need to select multiple columns but only have 2 of them which are distinct. For instance if i have
userid lastname firstname city country time 1 jones tom lon gb 2:25 2 wall paul la usa 2:30 1 jones tom lon gb 2:50 3 smith jane ny usa 2:55
what i would want to do is select all the columns but avoid duplicate lastname-firstname combination rows. The problem is if i use a group by i have to include all the columns and because time is different i will get tom jones twice. a way of getting round this so i can select all the columns but only 1 row of tom jones.
I have got the following error while executing below Query.
ORA-01791 'Not a SELECTed expression'
select distinct sgbstdn_levl_code from sgbstdn,spriden where spriden_pidm = sgbstdn_pidm and spriden_id = '200076543' order by sgbstdn_term_code_eff desc;
The above Query is not working with Distinct & Order By clause are present and by joining two tables. I need the distinct values of levels in Descending order of Terms.
The table creation and Data insertion script is attached with the message.Basically I want to sort all the data based on the order by clause and then remove duplicates from the TSKID column and get distinct TSKIDs in the same order.I have below query to sort data:
SELECT * FROM piwingetworkitems_vd ORDER BY profilepriority, authdptpriority, returnpriority ASC, priority DESC, effdate, tskid
But when I add a DISTINCT to the query, it does some kind of random sort and doesn't return the data as per above ORDER BY query and ignoring the SORT order.
SELECT DISTINCT tskid FROM (SELECT * FROM piwingetworkitems_vd ORDER BY profilepriority, authdptpriority, returnpriority ASC, priority DESC, effdate, tskid)
Is there any way to select the DISTINCT taskids ordered as per requirements?
I had to create a new column in a particular table now i want to insert the values in that column though the other columns are already populated I entered the command (insert into Product(STANDARD_PRICE) values(895.99) when i hit return it says cannot enter null value into (SYSTEM .PRODUCT. PRODUCT_ID) product_id is the PK which is the first column STANDARD_PRICE is the last column in my table...how do i enter the values into that column without receiving this error or having to effect the other columns?
I have a collection of objects built in a PL/SQL program.
I want to keep only the distinct elements of this collection for the rest of the program.
I failed to find the correct way to do it
For instance (the actual object is far more complex containing object attributes itself), with the following types:
drop type t1b / drop type t1a / create or replace type t1a as object ( v1 integer, v2 integer ) / create or replace type t1b as table of t1a / I have the following variable:
v t1b := t1b(t1a(1,2),t1a(1,2));
And I want to get only one "t1a(1,2)" in my collection.
My first idea (actually the second one but it does not matter) was to use DISTINCT:
SQL> declare
2 v t1b := t1b(t1a(1,2),t1a(1,2)); 3 begin 4 select distinct t1a(v1,v2) bulk collect into v from table(v); 5 dbms_output.put_line(v.count); 6 end; 7 / declare * ERROR at line 1:
ORA-22950: cannot ORDER objects without MAP or ORDER method ORA-06512: at line 4
As I said the object is far more complex and builting a MAP function is quite tedious (but I will do it if there is no other way).
The next idea was to use multiset operators:
SQL> declare 2 v t1b := t1b(t1a(1,2),t1a(1,2)); 3 begin 4 select v multiset intersect distinct v into v from dual; 5 dbms_output.put_line(v.count); 6 end; 7 / 1
PL/SQL procedure successfully completed.
This works well but I suspect this is not the correct way and there is one to do it in PL/SQL but currently failed to find it.
From the above duplicates I would like to get only 1 distinct record based on latest update time (when using distinct on a sub-query since OBID is unique again returning all recds)
I am expecting results like: DocNo|Title| Revs|UpdateTime|OBID DOC-101|DESCRIPTION1|1|2/28/2004 11:37|6108-9 DOC-201|DESCRIPTION2|0|4/24/2005 16:47|7900-1 DOC-301|DESCRIPTION3|3|2/21/2007 7:26|6869-4 DOC-304|DESCRIPTION4|3|8/22/2007 9:31| 39208-1
