Hi gurus,

If a SQL query with Inner, left to join external and external resources right how its works.

Thank you

Need help with joins Oracle

Hi all
Any new on Oracle Sql and I need expert input to solve a problem I have to join Oracle.
Have a requirement as below, my reading of request as below.
SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB
WHERE A.PRIMARY_CED = B.CED_ID (+)
AND B.LOB = C.LOB_DESCR (+)
AND B.LOB_IND (+) = 'Y '.
AND A.GCI IN
(
'339492963',
'339850821');
Output current:
GCI LOB_IND CED_ID LOB_DESCR
339850821 Y 7905108 banking services for businesses
Null Null null 339492963
Power required:
GCI LOB_IND CED_ID LOB_DESCR
339850821 Y 7905108 banking services for businesses
339492963 7859659 null null
In the table B (CLIENT) for a ced_id there will be several entries.
Select ced_id, LOB_IND from CLIENT b where b.ced_id = '7905108';
ced_id LOB_IND
7905108 IS
7905108 null
7905108 null
Select ced_id, LOB_IND from CLIENT b where b.ced_id = 7859659;
ced_id LOB_IND
7859659 null
7859659 null
so when writing of the main request, I took B.LOB_IND (+) = 'Y' condition, since I added this condition and catches of outer join.
the ced_id for "7859659" is not coming in the query below.
SELECT A.GCI, B.LOB_IND, B.CED_ID, C. LOB_DESCR OF CUSTOMER, CUSTOMER b, C from LOB
WHERE A.PRIMARY_CED = B.CED_ID (+)
AND B.LOB = C.LOB_DESCR (+)
AND B.LOB_IND (+) = 'Y '.
AND A.GCI IN
(
'339492963',
'339850821');
Output current:
GCI LOB_IND CED_ID LOB_DESCR
339850821 Y 7905108 banking services for businesses
Null Null null 339492963
Is it possible that the query can be modified to get the below output with CED_ID for B.LOB_IND-> case of Null.
Power required:
GCI LOB_IND LOB LOB_DESCR
339850821 Y 7905108 banking services for businesses

Your entered very necessary.
Thank you
Be great if someone could have provide some suggestions.

Use ANSI joins:

SELECT A.GCI, B.LOB_IND,
B.CED_ID,
C.LOB_DESCR
CUSTOMER A
LEFT JOIN
CLIENT b, C from LOB
ON)
A.GCI IN)
'339492963',
'339850821'
)
AND
A.PRIMARY_CED = B.CED_ID
AND
B.LOB_IND = 'Y '.
)
LEFT JOIN
C LOB
ON)
B.LOB = C.LOB_DESCR
)

While problems brought together three tables in Oracle
Hello

I'm trying to join the three tables in Oracle, but get unexpected results. Here it is the situation.

Table A has 10 rows and I want the line with Max date, table B has 20 rows and I want the line with Max date, so these 2 tables, I want 2 rows. Similarly, there are 10 tables with a huge amount of data.
So I created another table called table key and extract the name of the Table, the Table key (common across all the tables and plan called of code) and entered into force (it is a date max)

If key table now has a line of each table.

When I joined the table a (E221), table B (E227) and key table with query below, it does not result in any line. Can you please on how it should be resolved. Here it is the data from 3 tables.

Table A (E221)
PLAN_CODE DATE CAR GRP
12040005 19900801 1204 0005 20
12040005 19850201 1204 0005 19
12040005 19840801 1204 0005 20
12040004 20080806 1204 0004 20

12040004 20010730 1204 0004 20

TABLE B (E227)

12040005 19850201 1204 0005 0005
12040005 19840801 1204 0005 0080

12040004 20070901 1204 0004 6782
12040004 20051101 1204 0004 6782

Key table

12040004 20080806 E221
12040005 20080806 E221
12040004 20091001 E227
12040005 20091001 E227

Query used
SELECT E221.*,
E227.*,
KEY_PLAN_CODE.*
OF E221
JOIN INTERNAL KEY_PLAN_CODE
ON KEY_PLAN_CODE. EC_PLAN_CD = E221. EC_PLAN_CD AND KEY_PLAN_CODE. MAX_EFF_DATE = E221.cg_cvr_BS_EFF_DT
AND KEY_PLAN_CODE. EC_TRAN_CODE = E221. EC_TRAN_CODE
JOIN IN-HOUSE E227
ON (KEY_PLAN_CODE. EC_PLAN_CD = E227. EC_PLAN_CD
AND E227. PLAN_EFF_DT = KEY_PLAN_CODE. MAX_EFF_DATE
AND KEY_PLAN_CODE. EC_TRAN_CODE = E227. EC_TRAN_CODE)

Any suggestions would be helpful.
I'm still a little confused as to what should be returned.

Your key table includes:
12040004 20080806 E221
12040005 20080806 E221
12040004 20091001 E227
12040005 20091001 E227

I suppose you want returned:
E221 line with plan_code 12040004 and the date 20080806
E221 line with plan_code 12040005 and the date 12040004
Line E227 with plan_code 12040004 and the date 20091001
Line E227 with plan_code 12040005 and the date 20091001

Your query returns original nothing because, for example, the line containing plan_code 12040004 and date 20080806 can does not match anything in the E227 table with this plan_code and the date.

I think you are saying that what you want is, for each value of different plan_code, you want recording E221 corresponding to "E221" key_table folder with the date of the registration, and you also want to record E227 corresponding to "E227" key_table folder with the date of registration. I also guess that there must be a record E221 both INAT E227, otherwise nothing is returned for this plan_code.

I suppose also that there is no record more "E221" and no more a 'E227' record in key_table for any value special plan_code.

In this case, you want to do something like this:
```
SELECT K.*, E221.*, E227.*
FROM
(
  SELECT k221.ec_plan_cd, k221.max_eff_date AS e221_date, k227.max_eff_date AS e227_date
  FROM key_plan_code k221
  JOIN key_plan_code K227
  ON k227.ec_plan_cd = k221.ec_plan_cd
  WHERE k221.ec_tran_code = 'E221'
  AND k227.ec_tran_code = 'E227'
) K
INNER JOIN E221
ON (E221.ec_plan_cd = K.ec_plan_code AND E221.cg_cvr_bs_eff_dt = K.max_eff_date)
INNER JOIN E227
ON (E227.ec_plan_cd = K.ec_plan_code AND E227.plan_eff_dt = K.max_eff_date)
```
The subquery K Gets a line for each ec_plan_cd in key_plan_code with a record 'E221' and a «E227» folder

I'm assuning ec_tran_code is the column of key_plan_code with 'E221' and 'E227. " If this is not the case, use the correct name.

Hi Srikanth,

It is usually better to create a separate scheme for the scheme of work, but you can keep the data and schema of work even. Also in your error log, the error should now be to the right of the IKM? No LKM. Try changing the logical schema name and see if it works.

Thank you

How can I add data file to an existing table on Oracle RAC ASM with no OMF? Thank you!

Hello

So I guess you have some files in ASM, see your first existing file structure

Select file_name

from dba_data_files;

and to add to an existing table, the example below (even if you're better sticking with OMFs!)-is that what you are looking for?

SQL > create tablespace TEST1

2 datafile '+ DATA' size 1 M;

Created tablespace.

SQL > select file_name in dba_data_files;

Ongoing replication of the selected tables from Oracle to SQL Server

Hi all
How can we replicate selected tables to Oracle 11 g for SQL Server 2008/2012?
Is GoldenGate the only option
No matter who did it before or have the steps to do it?
Thank you

Define "replicate".

If you have no budget, you can open a connection directly from SQL Server to Oracle, or vice versa. In Oracle, they are called links DB; in SQL Server, they are called "linked servers".

Datanamic also have tools that claim to do the cross-DB replication. I have no experience with them and is not an endorsement - I know they exist.

Optimizer (?) excluded table join

Hello
I have a problem. We use 10.2.0.5.0 database. I discovered very weird behavior when running a very simple three-table join. I tried two forms of the same join. The first was:
SELECT
NVL(c.cen_za_ks,1) as a2,
NVL(c.cen_za_kg,1) like a3
Of
vymenny_urad VIEW
JOIN IN-HOUSE
Krajina K ON vu.vymur_krj_id = K.KRJ_ID
JOIN IN-HOUSE
CENNIK_090 C ON C.CEN_KR_KOD = K.KRJ_KOD
WHERE
vu.vymur_id = AND c.cen_kategoria = 369 has '
Execution plan for this selection is:
-----------------------------------------------------------------------------------------
| ID | Operation | Name               | Lines | Bytes | Cost (% CPU). Time |
-----------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT |                    |     4.    88.     5 (0) | 00:00:01 |
|   1. NESTED LOOPS |                    |     4.    88.     5 (0) | 00:00:01 |
|* 2 |   INDEX UNIQUE SCAN | IX_PK_VYMENNY_URAD |     1.       |     1 (0) | 00:00:01 |
|* 3 |   TABLE ACCESS FULL | CENNIK_090 |     4.    56.     3 (0) | 00:00:01 |
-----------------------------------------------------------------------------------------
Information descriptor (identified by the operation identity card):
---------------------------------------------------
2 - access("VU".") VYMUR_ID "= 369)
3 - filter("C".") CEN_KATEGORIA "(='D')"

Thus, for specific settings, I had 8 rows

If I added any column of krajina of table columns selected like this:

SELECT
krj_id,
NVL(c.cen_za_ks,1) as a2,
NVL(c.cen_za_kg,1) like a3
Of
vymenny_urad VIEW
JOIN IN-HOUSE
Krajina K ON vu.vymur_krj_id = K.KRJ_ID
JOIN IN-HOUSE
CENNIK_090 C ON C.CEN_KR_KOD = K.KRJ_KOD
WHERE
vu.vymur_id = AND c.cen_kategoria = 369 has '

the execution plan has been changed to:

----------------------------------------------------------------------------------------------------
| ID | Operation | Name               | Lines | Bytes | Cost (% CPU). Time |
----------------------------------------------------------------------------------------------------
|   0 | SELECT STATEMENT |                    |     1.    29.     6 (0). 00:00:01 |
|   1. NESTED LOOPS |                    |     1.    29.     6 (0). 00:00:01 |
|   2.   NESTED LOOPS |                    |     1.    15.     3 (0) | 00:00:01 |
|* 3 |    TABLE ACCESS BY INDEX ROWID | VYMENNY_URAD |     1.     8.     2 (0) | 00:00:01 |

4 - access("VU".") VYMUR_ID "= 369)
6 - access("VU".") VYMUR_KRJ_ID '=' K '. ("' KRJ_ID")
7 - filter("C".") CEN_KATEGORIA "= A"AND "C". ". CEN_KR_KOD '=' K '. ("' KRJ_KOD")
and result set had only 2 rows, because of the restriction imposed by the table "krajina", which was not in the first case considered by the optimizer.
Y at - it a reasonable explanation for this behavior? Have someone at - he found a reliable solution?
Thanks for help
Miro

I received your email

I saw something strange in the, but then realize that the elimination was logically invalid and created a simple demo.

If you look at the two surviving tables SEPARATELY it seems reasonable to eliminate the krajina - but when you look at the other two tables at the same time you realize that you have a line in krajina which corresponds to a line in vymenny_urad but not in cennik_090 and a line that does the opposite. In this case, the other two lines survive when you eliminate the krajina, but they disappear if krajina is located in the middle of the join.

The problem is solved by 11.1.0.7

You have received the reply above. Archive of flashback stores data.

See the link provided above to CREATE an ARCHIVE of FLASHBACK in the doc of SQL language

Specify the table space where the data archived for this flashback data archive referring to be stored. You can specify that a tablespace with this clause. However, you can then add tablespaces to archive flashback with a statement ALTER FLASHBACK ARCHIVE database.

The data is moved to storage of archives and restored from there when you query for archive flashback.

Save a table in Oracle R12
Dear members,

Are the steps to save a table in Oracle R12 is identical to the one off Oracle 11i?

I want to say can we use the same ADD_DD package and record all custom tables and their corresponding columns?

Can someone please shed some light on this.

Thanks in advance.
Yes - same as in 11i - pl see the documentation - http://docs.oracle.com/cd/E18727_01/doc.121/e12897/T302934T303920.htm#I_sx2Daoltabl

I am new to FDQM I need to connect from the table Source 'Oracle '...
This is the first time for me to do this, you have any Document to the connection on the Source table in Oracle, to any table target using FDQM
is it valid?
If valid how can I make the integration with FDQM...?
I called ODI,
Can be defined from any source to any target,
In FDQM I can set to take data from the Source of the table is Oracle to load in the EPM or any target system.

Published by: Joe on December 10, 2011 19:52
Please refer to paragraph "Example of Script integration" on page 200 of the FDQM 11.1.2 administration guide.
This example connects to a SQL Server table (you may have to tweak it a little so you can connect to Oracle table), but the example can give you a good impression of what is necessary to establish a direct link.

difference in size of the Table in oracle and timesten
Hi all

I have a large table with 2 million records,

I see no big difference in the size of the table in oracle and Timesten
In oracle table size to 4 GB, but in Timesten is arround 15 GB (using ttSize for 2 M lines)

Could you please tell me what could be the cause of this difference?
Is the size of the table in Timesten is always more than oracle?
What are the factors and parameters affecting the size of Perm?
It is typical for the storage needs for a DataSet to be significantly larger in TimesTen in Oracle. This is due to the Organization of the very different internal storage in TT from Oracle; Oracle is optimized to save space while TT is optimized for performance.

Ways to minimize these costs are:

1. make sure you use TimesTen 11.2.1. This has some characteristics compare compact (minor) and earlier versions.

2 assess the use of numeric types; native types TimesTen (TT_TINYINT, TT_SMALLINT, TT_INTEGER and TT_BIGINT) use less space than MANY and longer by the effective calculation as well.

3. check use of data of variable length (VARCHAR2, VARBINARY, NVARCHAR) and the trade-offs between online and online storage (see documentation for the compromise between these options stirage TT).

Even when you use the foregoing, you will still see a storage important "inflation" for TT from Oracle.

What are the different types of tables in oracle - please help
I want to know the different types of tables of orcle... Please help me
There are seven types of tables in Oracle.

1. organized bunch of tables
2 index organized tables
3 clustered index tables
4 hash clustered tables
5. nested tables
6. global temporary tables
7 tables of objects
Source: http://www.adp-gmbh.ch/ora/concepts/tables.html

But if you ask the types of tables in sense of the uses they are n types:
1 step tables
2. operational tables
3. functional tables
4. layout tables
5 archive tables
6. other tables

table join question
I have two tables joined via a pk/fk relationship. The main table has a field that indicates if a person entered the House (that's a request for home detention for minors) and to the left, or if it is still in the House.

1 = entered and left, 0 = always in the House.

The two tables are related through three fields (ID of the person, House ID, date of entry in the House)

I need a query to retrieve the records that exist in table 1 (the master) but do not exist in table 2 (retail) for (young) people who are STILL in the House. I need the query to run on the House n ° 2.

I tried a number of relationships to join, but none has been successful.

Any ideas on how to write this request will be appreciated.
The next time after table descriptions...

I think you're asking something like that:
```
select pt.*
from parent_table pt
where pt.field = 0
  and pt.home = 2
  and not exists
  (select 'a child row for this parent row'
   from child_table ct
   where ct.person = pt.person
     and ct.home = pt.home
     and ct.entry_date = pt.entry_date);
```

axis/axis here is the user and pwd to oracle 8i

Prakash is the name of a table in oracle 10g >

To export the database 10g PRAKASH table, use the 8i export utility.

log tables = prakash.log file = prakash.dmp exp = feedback = 100000 PRAKASH

Who is the owner of the table? You have the TNS entry for the 10g database in your NET80 folder. If this isn't the case, then put an entry in there. Then, when you are prompted for the user name

username:newcolsys@tns_alias/password

is that we can transform a GML table with oracle 11g?
I have a project with GML and this is the first time that I work with.
I just need to know if I can transform a normal table with oracle of GML.

I found that we can do this with xml using the simple features sql example:

SQL:
SELECT XMLElement (name 'Department',
XMLAttributes (deptno),
XMLAgg (XMLElement (name"employee", ename))) .getStringVal () as a RESULT
FROM scott.emp
GROUP BY deptno;

result:
< Department deptno '34' = >
ename < employee > < / employee >
< / Department >

< Department deptno = "35" >
ename1 < employee > < / employee >
< / Department >...

We can do something like this with oracle11g for GML instead of XML (when we have spatial data).

I hope that you have the answer or a reference that can help.
Thank you
Best regards
Hi, -.

We have the following conversion functions of GML and KML to/from SDO_GEOMETRY.
We both support GML2 and GML 3.1.1:

In 11.1.0.7, you will find the following functions:

SDO_UTIL. FROM_GML311GEOMETRY: Converts a fragment of geography markup language (GML 3.1.1) a spatial geometry.
SDO_UTIL. FROM_GMLGEOMETRY: Converts a fragment of geography markup language (GML 2.0) a spatial geometry.
SDO_UTIL. FROM_KMLGEOMETRY: Converts a KML (Keyhole Markup Language) of a Spatial geometry object document.

SDO_UTIL. TO_GML311GEOMETRY: Converts an object of spatial geometry to a fragment of language (GML version 3.1.1) geography markup based on the geometry types defined in the schema geometry.xsd Open GIS Consortium document.
SDO_UTIL. TO_GMLGEOMETRY: Converts an object of spatial geometry a geography markup language (GML 2.0) fragment based on the geometry types defined in the schema geometry.xsd Open GIS Consortium document.
SDO_UTIL. TO_KMLGEOMETRY: Converts a Spatial geometry object to a KML (Keyhole Markup Language) document.

See also User Guide Pro Oracle Spatial and Oracle Spatial for book of 11g Oracle database for more details and examples.

Please let us know if you have any other questions. We will be happy to help you.

I hope this helps.
