Sub query problem
Hi all

Problem with sub query.

Select * from where the team team_id in (team_id region selection);

If I run the query above is the length, but the problem is that I don't have team_id in the region table. How oracle to run this query. Please explain.

If I run select region team_id;

I got error like team_id invalid.

I'm using the version of oracle 10g.

Thank you.

Because of the determination of the scope.
Oracle uses the "team_id" of the outer query.

If you were to use:
```
select * from team  where team_id in (select region.team_id from region);
```
THEN, you will get an error.

Need help to write a sub query

Our environment - Oracle 10 g

Hi all
Need help to write a sub query to reach him here are examples of data using which iam trying to replace the value column in the table based on two other columns in the same table

Examples of data

ClaimNo flag LineNo Procedurecode
100 01 N MN4567
100 02 Y 7863
100 03 N MN8976
100 04 Y 9000
101 01 Y 8954
101 02 N MN6754
101 03 N MN7654
101 04 Y 8976
102 01 Y 1234
102 02 Y 2345
102 03 Y 3456
102 03 Y 4567

Each column of ClaimNo has several rows of data. But if column procedurecode for a claimNo starts with MN then all values associated with the claimno for the flag column should replace N

If the data must become like below

ClaimNo flag LineNo Procedurecode
100 01 N MN4567
100 02 N 7863
100 03 N MN8976
100 04 N 9000
101 01 N 8954
101 02 N MN6754
101 03 N MN7654
101 04 N 8976
102 01 Y 1234
102 02 Y 2345
102 03 Y 3456
102 03 Y 4567

Thank you

Order By in the Sub query

We cannot use ORDER BY in the Sub query.

select * from emp where emp_no in (select emp_id from dept order by dept_no )

Get the below error

ORA-00907: missing right parenthesis

Hello

user13024762 wrote:
To get the number of EMP table for maximum number of dept dept

If this is what you want, then do something like this:

select  *
from      emp
where      emp_no in (
                      select    MAX (emp_no) KEEP (DENSE_RANK LAST ORDER BY dept_no NULLS FIRST)
               from      dept
            )
;

or maybe

select  *
from      emp
where      emp_no  = (
                      select    emp_no
               from      dept
               where     dept_no = (
                                                SELECT  MAX (dept_no)
                             FROM    dept
                                             )
            )
;

Depending on what you want in the case of a tie.

select * from emp where emp_no in (select emp_no from dept where rownum =1 order by dept_no desc)

The subquery that you posted above does not necessarily return the line containing the largest dept_no, since ROWNUM is affected before ORDER BY is done.

I hope that answers your question.
If not, post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all tables and also post the results desired from these data.
Explain how you get these results from these data.

Problems with Sub query

Hello, I'm looking to create a sub query to display certain information. On the form that the information is entered, the user has the option to enter a phone number extension, as appropriate. If this is the case, I want the phone number to show as 555-867-5309 (x 1234). However, without the problem of controls, the (x) will be displayed without worrying and seems sloppy. Here is the code I have, please notify.

There will be two places, it will be necessary - for the telephone number of the applicant and the app (SME) contact information manager.

Thank you.

I think you can avoid the sub query thing simply by using the NVL2 function:

select ...
     , NVL2( pm.requester_ext
           , pm.requester_phone|| '(x'||pm.requester_ext ||')'
           , pm.requester_phone) "Requesters Number"
       ...
     , NVL2( pm.app_manager_ext
           , pm.app_manager_phone|| '(x'||pm.app_manager_ext ||')'
           , pm.app_manager_phone) "Manager Number"
       ...
  from protrac_master pm
     , ...

Performance issue with Sub query

Hi all
I have a requirement as there are two tables.
Columns in the table T1
-----------------------------------
enter_time TIMESTAMP - partitioned column
loc_num INDEX of index column-
Table T2
---------------------------
number of loc_num
VARCHAR2 (20) type1
VARCHAR2 (20) type2
Table T1 is to have 30,00000 files
Table T2 is to have 4 records
There is no application between T1 and T2.
Try to get one day date of the T2 based on the results of query sub.
Query:
SELECT * FROM T1
WHEN trunc (enter_time) = July 22, 15 '
and loc_num IN (select loc_num FROM T2 where = "XYZ" type1 and type2 = "PPP");
I tried with the sup of CO-RELEATED query, but it takes more than 30 minutes.
Do you have any idea to rewrite the query to make it faster in this scénarion.
Thanks in advance.
Kind regards
Sanjib

Hello

Columns in the table T1

-----------------------------------

enter_time TIMESTAMP - partitioned column

loc_num INDEX of index column-

Table T2

---------------------------

number of loc_num

VARCHAR2 (20) type1

VARCHAR2 (20) type2

Table T1 is to have 30,00000 files

Table T2 is to have 4 records

Do you have any idea to rewrite the query to make it faster in this scénarion.

Implementation plan would be useful here.

Assuming that enter_time is indexed, you can remove this trunc function.
```
select * from t1
where enter_time  >=  to_date('07/22/2015', 'mm/dd/yyyy')
  and enter_time  <   to_date('07/22/2015', 'mm/dd/yyyy') + 1
  and loc_num     in  (
    select loc_num from t2 where type1='XYZ' and type2='PPP'
  )
```

Hello

what you trying to do? A decree by a subselect in the useless statement.

Also use an order you need to add an option and change the IKM

Write the result of a query in ODI in file
Hi friends,

I'm using ODI 11 g.

In ODI I want to write the output of the query to a file unix below.

SELECT "H" | RPAD('SB9KT.) KTPRTO. EBSDATA. D0000000 ', '30', ' ') | RPAD (to_char (sysdate, 'YYYYMMDDHHMMSS'), 16, ' ')
DOUBLE;

Please suggest any entries.

Thank you

Select ambiguous column in Sub query
I get an error "ambiguous column" when I question using a sub select. Here's my query:

Select *.
(select
c.custody_id,
c.person_id,
n.first_name,
n.last_name,
z.usms_number,
c.start_date,
c.end_date,
c.district_office_id,
CBC.custody_id,
c.update_date,
c.update_user_id
Guard c,.
custody_booking_pkg_components Radio-Canada,
z_migrate_usms_number z,
district_office do,
District d,
person p,
n name
where
c.person_id = p.person_id and
z.person_id = p.person_id and
z.Ordinal = 1 and
c.custody_id = cbc.custody_id (+) and
p.name_id = n.name_id and
do.district_id = d.district_id and
c.district_office_id = do.district_office_id and
d.district_id = 99 by c.update_date desc order)
where rownum < = 10;

I understand why "ambiguous column" average error, but I don't see which column is ambiguous. I ran the select sub by itself and it works correctly, but when combined with the external selection it fails.
Hello

You have two columns called custody_id.
It is normal to have names duplicated in a query, but not in a table or view (and which includes a view online, you have).

Type a unique name for each column.

query in odi
Hello

How to implement this query (select * from tab1 less select * from tab2) in ODI.
Hello

Sure. :)

1. in your underlying DB for example used DB run the query below

Create view odi_minus in select * from tab1 less select * from tab2.

2 open the designer of-> -> reverse-> check the view (United Nations check all and click APPLY).

Then go on selective audit data reverse selective reverse tab, new store, objects to reverse.

3. in the list, select the view whose u created odi_minus in our case, click on on the back.

4. you will find views as data store in your model tree, use it as a source in your interface.

Hope it's clear now.

Thank you

FETCH ONE RECORD IN THE SECOND TABLE OF CORRELATED SUB QUERY

Hi all
I have provided the script below, I want to single fecth record in the second table in the join query,
based on the example below, I want to go get one record of the table emp2 what matches with the emp_id of table emp1, please note emp2 may contain more record for the emp_id emp1 which respects
all records can be selected in the table emp2.
DROP TABLE emp1.
CREATE TABLE emp1 (emp_id NUMBER);
INSERT INTO emp1 VALUES (1);
INSERT INTO emp1 VALUES (2);
COMMIT;
DROP TABLE emp2.
CREATE TABLE emp2 (emp_id NUMBER, emp_name VARCHAR2 (100));
INSERT INTO emp2 VALUES (1, 'Name1');
INSERT INTO emp2 VALUES (2, 'Name2');
INSERT INTO emp2 VALUES (1, 'Name3');
INSERT INTO emp2 VALUES (2, 'Conjoint4');
COMMIT;
SELECT * from emp1.
SELECT * from emp2.
SELECT T1. EMP_ID, MIN (T2. EMP_NAME)
FROM EMP1, EMP2 T2 T1
WHERE T1. EMP_ID = T2. EMP_ID
GROUP T1. EMP_ID;
My output should be the same as the result set of query above, but I don't want this logic, please provide the solution by using a different logic, thanks in advance.

Thanks for your comments :-)

My business logic will change to 'Fetch N second timeline table', that's the reason why I asked for a different approach, if I use max, min to achieve this does not allow me to evolve dynamically.

Although logic has not been expressed at all in your original question, so good job I asked.

You could do something like:

1 with emp1 (select 1 as the emp_id of union double all the)
2. Select 2 double

7. Select 2, 'name 4' double union all.
8 select 1, 'name 5' from dual union all '.
9 select 2, 'name 6' from dual '.
10               )

12. end of test data

Help with sub query!

I have a question where the upper version value for an id is to be retrieved. I wrote a query but its time consuming. Please help me with this request.
Create feed table (c_id number, number, version number);
create the table of negotiations (identification number, the version number);
Query:
SELECT ID, VERSION
Feed, process t
WHERE a.c_id = 1 and a.id = t.id AND EXISTS (d.SELECT VERSION, d.ID
FROM (SELECT MAX (VERSION), ID
FROM (SELECT ID, VERSION
B power supply, treat the t1
WHERE b.c_id = 1
AND t1.ID = B.ID) c
GROUP BY ID) d
WHERE a.ID = d.ID AND a.VERSION = d.VERSION);

Please check this query:

Select q.id, q.version

from (select f,

DENSE_RANK() over (partition by f.id f.version desc order) rn

power f) q

Join (select *)

(select p,

DENSE_RANK() over (partition by order by p.version desc p.id) rn

process p)

where rn = 1) p

on p.id = q.id

and p.version = q.version

where q.rn = 1

A row of Sub query returns more than 1 row!
I'm trying to update the values in one table from another table and get the error: void line query returns More Than 1 row.

I want to PRV_NAME B chart updated in the table A PRV_NAME where A.PRVID = B.PRVID where B.PRV_TYPE = M"

The two paintings were all unique PRVID, however, table B has PRVID that have the same name. So the data in table B can look like this:

PRVID PRV_NAME
1234 PHOENIX MED
1235 MED BAG
1236 MED BAG
1237 OVERLAND
etc...

So, as you can see are the unique PRVID, but not the PRV_NAME. Is this the reason why I get this error?

I do not build the tables and have no control over what is put in them. If this is the reason for the error, is there a way to fix this?

For reference, here's the request. Maybe there's something wrong with that?
