I have a table as follows.
Id Code Indicator
1 AB
1 CD Y
1 EF
2 BC Y
3 AB
4 GH
4 AB Y
5 CD
5 BC
Now I need to retrieve the ID's which do not have any indicator associated to them. In this case, the retrieved rows should be
ID Code Indicator
3 AB
5 CD
5 BC
Thanks to y'll I got it in sql but I have the same table as a view in Oracle discoverer. How do i write a report to get the same result?All help much appreciated!!
This should do it (Warning: Untested):
select id, code
from table
where id not in (select id from table where indicator='Y')
SELECT *
FROM TABLE t1
WHERE T1.ID in (SELECT
t2.ID
FROM Table t2
GROUP BY t2.ID
HAVING MAX(t2.Indicator) = 'Y')

EXPLAIN SELECT S.ITEMID, X.STATUS
FROM
(select itemid,itemdescription from A WHERE parent_itemid IN(SELECT ITEMID FROM A WHERE itemtype='CT') AND itemtype='SK' AND id='02') S,
(select s1.itemid from s1,s2 where s1.itemid=s2.itemid and status='RC' ) X
where S.itemid=X.itemid
It is not correlated subquery that makes problems, but syntax. Not just explain, but explain plan for.
I don't have your tables so I used Scott's (properly joined):
SQL> explain plan for select s.dname, x.ename
2 from (select d.deptno,
3 d.dname
4 from dept d
5 where d.deptno in (select b.deptno
6 from dept b
7 where b.deptno = 10
8 )
9 ) s join
10 (select e.deptno,
11 e.ename
12 from emp e
13 where e.deptno = 10
14 ) x
15 on s.deptno = x.deptno;
Explained.
SQL>
In your case, presuming that everything else is correct,
explain plan for select s.itemid, x.status
from (select a.itemid,
a.itemdescription
from a
where a.parent_itemid in (select b.itemid
from a b
where b.itemtype = 'CT'
)
and a.itemtype = 'SK'
and a.id = '02'
) s join
(select s1.itemid
from s1 join s2 on s1.itemid = s2.itemid
where s1.status = 'RC' --> which table does STATUS belong to?
) x
on s.itemid = x.itemid;
I'd also suggest you to always use table aliases because it is not clear what belongs to which table. For example, status = 'RC' - without alias, it is impossible to know which table has it. If both, you'd have ambiguity.
Finally, write formatted queries. Mess you posted is difficult to read and understand. Most modern GUI tools have built-in formatters; I suggest you use it. Or, use one of online formatters. Or, format it manually. Just try not to do what you're doing now.
The correct syntax for EXPLAIN is:
EXPLAIN PLAN FOR
SELECT...
Also in the 2nd subquery you must select the column status because you want to select it in the outer select:
EXPLAIN PLAN FOR
SELECT S.ITEMID, X.STATUS
FROM
(select itemid,itemdescription from A WHERE parent_itemid IN(SELECT ITEMID FROM A WHERE itemtype='CT') AND itemtype='SK' AND id='02') S,
(select s1.itemid, status from s1,s2 where s1.itemid=s2.itemid and status='RC' ) X
where S.itemid=X.itemid
Also status should be qualified by the table's name just to avoid any ambiguities.
I have a table A in Schema1 and table B in Schema2.
The tables have different columns.
Table A:
ID1 Name Code
-------------------------------
1 Skyler A0
2 Amanda A1
3 Rachel B0
4 Harvey C0
5 Louis B1
Table B:
ID Names Enterprise Modified_Date
------------------------------------------------------
1 Amanda 1 2018.08.10
2 Skyler 1 2018.08.11
As depicted, Schema1.A.Name = Schema2.B.Names
I want to insert the values "Rachel,Harvey and Louis" from A.Name into B.Names.
For b.ID, i have a sequence in place. Enterprise column is always 1 and modified date can e sysdate.
How can i achieve this in PL/SQL?
use insert Statement with select statement
insert into tabB (names,Enterprise,Modified_Date )
select Name,1,sysdate from tabA where Name in ('Rachel','Harvey','Louis');
You can do this by using below query.
insert into tableB (names,Enterprise,Modified_Date )
select Name,1,sysdate from tableA where Name not in (select distinct(Name) from tableB);
I have Two table T1 and T2.
T2 is Making From T1.
T1 table:
ID Country Name
1 Bangaldesh
2 India
3 USA
4 UK
T2 table making from T1 ID
ID From T1 table C1 From T1 table C2
1 1(Bangladesh) 2(India)
2 2(India) 3(USA)
3 2(India) 1(Bangladesh)
4 2(India) 1(Bangladesh)
How can i Joining now Two Table for laravel query builder?
I need to show country name by ID
Thanks for Advance.
Check the documentation on joins.
DB::table('T2')->join('T1', 'T1.id', '=', 'T2.id_column')->get();
Assuming that the column in T2 that has the T1 id is called id_column.
I need help with my SQL Query I have Two tables that i need to join using a LEFT OUTER JOIN, then i need to create a database view over that particular view. If i run a query on the join to look for name A i need to get that A's latest brand "AP".
Table 1
ID name address
-----------------------
1 A ATL
2 B ATL
TABLE 2
ID PER_ID brand DATEE
--------------------------------------------
1 1 MS 5/19/17:1:00pm
2 1 XB 5/19/17:1:05pm
3 1 AP 5/19/17:2:00pm
4 2 RO 5/19/17:3:00pm
5 2 WE 5/19/17:4:00pm
I tried query a which returns correct result but i get problem 1 when i try to build the database view on top of the join. I tried query b but when i query my view in oracle sql developer i still get all the results but not the latest.
query a:
SELECT * from table_1
left outer join table_2 on table_1.ID = Table_2.PER_ID
AND table_2.DATE = (SELECT MAX(DATE) from table_2 z where z.PER_ID = table_2.PER_ID)
Problem 1
Error report -
ORA-01799: a column may not be outer-joined to a subquery
01799. 00000 - "a column may not be outer-joined to a subquery"
*Cause: <expression>(+) <relop> (<subquery>) is not allowed.
*Action: Either remove the (+) or make a view out of the subquery.
In V6 and before, the (+) was just ignored in this case.
Query 2:
SELECT * from table_1
left outer join(SELECT PER_ID,brand, max(DATEE) from table_2 group by brand,PER_ID) t2 on table_1.ID = t2.PER_ID
Use row_number():
select t1.id, t1.name, t1.address, t2.id as t2_id, t2.brand, t2.datee
from table_1 t1 left outer join
(select t2.*,
row_number() over (partition by per_id order by date desc) as seqnum
from table_2 t2
) t2
on t1.ID = t2.PER_ID and t2.seqnum = 1;
When defining a view, you should be in the habit of listing the columns explicitly.
I have a table X
ID A B
--------------
1 abc 27
1 - 28
2 - 33
3 xyz 41
3 - 07
I need output as
ID A B
--------------
1 abc 27
2 - 33
3 xyz 41
I tried doing
max(A) OVER (PARTITION BY ID) as the_value
but it did not work. I can still see all the rows in the output table.
I was wondering if somebody has come across a similar situation and has a solution to this ?
you can use this simple trick for getting the full record for which some column is maxed:
select original.* from
(select ID,max(B) as B from Tbl group by ID ) maxB
inner join
(select * from Tbl ) original
on original.ID = maxB.ID and original.B = maxB.B
now this is of course an overkill code. you can also do:
select Tbl.* from
(select ID,max(B) as B from Tbl group by ID ) maxB
inner join
Tbl
on Tbl.ID = maxB.ID and Tbl.B = maxB.B
but the first version is more of a template to do whatever you want with further columns, fields, conditions joins etc.
