How to query with limited information

It is possible to query if I dont know the table's and column's name?
- I know the column's name but I dont know which table its belongs to, so how should I query? The purpose of this query to define which table its belongs to.
- I know the data's name but I dont know which column and table its belongs to, so how should I query? The purpose of this query to define which table and column its belongs to.
- I only know the database and schema where all the datas belongs to
Any suggestion to solve this problems?

select
table_name
from all_tab_cols
where column_name = :your_name
and owner = :your_schema_nameSeems like a reasonable starting point.

How to query table/comment information and lookup table names from PKs?

I am trying to figure out whether I can query the Oracle meta-data to look for:
a) comments on tables and fields matching a certain text pattern. If possible I would LIKE the text pattern matching not to be case-sensitive. Am I looking within the right meta tables?

b) I was trying to look up a text named 'PKa200030' which showed up within an application upon which we are developing. The application uses Oracle 11g Enterprise Edition. However, I could not find the name anywhere when querying all_constraints, so I am not sure how to trace back the table name / package name, by knowing what seems to be a primary key constraints, any ideas please?
select c.table_name,c.constraint_name, --c.r_constraint_name,
cc.table_name
from all_constraints c
inner join all_constraints cc on c.r_constraint_name = cc.constraint_name
See http://stackoverflow.com/questions/3210743/viewing-oracles-metadata-about-primary-foreign-key-constraints.
c) I am not sure whether it is possible to draw a database entity model, perhaps using software, assuming that the primary/foreign keys have been already defined within Oracle 11g. Is software available to do this?

Query with collective information from MD04 in detail

Hello gurus. I have a question about Infosets.
Iu2019ve being asked to create a query that shows the information from transaction MD04, but for multiple materials. It should be a list that essentially lists every MD04 record for material in our plant, one after the other.
I found a Function called MD_STOCK_REQUIREMENTS_LIST_API which contains this information. The problem is, this function exports the detailed data to a structure called MDEZ and the header data to a separate one called MDKP.
I created an Infoset using u201CData Retrieval by programu201D and I typed MDEZ as the structure. I then coded the retrieval of data under the u201CData Reading Programu201D tab.
The problem is, the MDEZ structure inside Function MD_STOCK_REQUIREMENTS_LIST_API doesnu2019t have the material number; this is exported to a separate one called E_MDKP.
My question is; how can I also have the contents of MDKP added to this Infoset? When I create it, it only lets me use one single structure, I cannot also add MDKP.
I tried creating an additional field just for the MATNR, but those extra fields cannot read what I coded under the u201CData Reading Programu201D tab. I tried to use a second internal table to drop the values of E_MDKP, and then loop it to fetch the MATNR, but I canu2019t add it to the additional field nor can I add it to a second structure.
I made a query and it shows the MDEZ data correctly; I get one line per item found in MD04 for the materials I imported from our Plant, but I donu2019t know which material is which because that info is in the other structure MDKP.

Thanks for your reply. if you don't mind me asking, how can I create my own structure to add it to the Infoset?
When I create the infoset, I can either make from a Table Join, a Logical Database or data Retrieval. In the Table Join I cannot use structures, and under Data Retrieval, I can only use one of them.
Is there a way to create a temporary (or permanent) structure that would contain MDEZ and the extra field MATNR that I need?
Please advise.

How to query with wild card

hi friends
we have a requirement where if the user enters a letter in a field of selection-screen, he is supposed to get the fields details with its prefix entered in the selection-screen
eg: if user enters P and give execute
he needs to get the details of the particular field starting with P
how to code this
with regards
s.janagar

Hi,
Here wildcard character '%' can be used as pattern code. Character and then the '%' sign signifies that all values with character as first letter will be searched upon.
In your case use of like 'P%' in the where clause of the select statementr should solve the issue. e.g.,
select * from <tabname> into table <internal table> where <fieldname> like 'P%'.
searches all entries from table <tabname> and places them in internal table <internal table> where the field <fieldame> begin with P.
Thanks and Regards,

Adaptor with State information

Hi
We are in the process of migrating legacy system to ESB architecture and would like to get your input in how to deal with state information.
Current system has one system (A) that takes input from another system (S) and outputs to many nodes of system (C).
S --> B ---> N number of C
System C is high load, read-only, parallel system (totally independent of each other). System A's job is to provide a buffer between System S, so only relevant changes will trickle to System C, hence removing any unnecessary processing/load to potentially hundreds of nodes of System C. System S is a repository of all the data, superset of what System C needs.
We are trying to re-architect system A to be an ESB adaptor that reads from System S and exports data to System C (The transport mechanism between system A and C are not to be changed. We will continue to use existing file distribution mechanism. And this isn't the issue; I am only mentioning it here for completeness.)
Question is, how would you create this adaptor that would know the state of System C (i.e. know what data has been already pushed out via file distribution) and compute relevant delta from the incoming changes from System S? As in the legacy system, this adaptor MUST provide only the deltas to System C, so to not create any unnecessary processing.
In the legacy architecture, System A had a DB that mirrored the data pushed out to System C. But now the proposal is to get rid of this DB and some how compute the same delta.
Other than using in-memory DB, what other ways are there? Does Oracle SOA Suite provide something to deal with this?
Thanks in advance,
JY

Infoset query with KNB1 customer's ADRC information

Hello,
An explanation into the problem:
I'm trying to create an infoset query with KNA1, KNB1 and ADRC which would do the following:
In KNA1-SORTL we hold customer numbers which can be found from KNB1. This query should:
Display KNA1-KUNNR and relevant address data for this customer via connection KNA1-ADRNR and ADRC-ADDRNUMBER. Then it should check KNA1-SORTL- field and if it corresponds to KNB1-KUNNR, it should go back to KNA1 with this KUNNR and display all this customer's relevant address data via this customer's KNA1-ADRNR to ADRC-ADDRNUMBER.
I'm relatively new to infoset coding and ABAP in general, plus I'm self- taught so please bear that in mind.
I'll give an example as to what I've managed to do so far. In SQ02 I joined tables KNA1(left outer join)KNB1 and KNA1(join)ADRC and created an extra field ZADRNR to see if I could display the ADRNR for the customer number found in KNB1.
Something along the lines of:
IF KNB1-KUNNR = KNA1-SORTL.
SELECT SINGLE ADDRNUMBER FROM ADRC INTO ZADRNR
WHERE ADDRNUMBER = KNA1-ADRNR.
ENDIF.
Obviously this doesn't work. Pseudocode would look like this:
Check field KNA1-SORTL
IF KNA1-SORTL = KNB1-KUNNR THEN
GO BACK TO KNA1 with this KUNNR and display it's ADRC.
KNB1 sadly doesn't maintain an ADRNR of it's own, or this would be much simpler.
Any help or advice is much appreciated, so far I've only been coding a few lines in infosets with ABAP so I'm not all that familiar with it. I've managed to create several queries through trial and error, mostly, and this forum and it's articles have helped a great deal.
Please let me know if I should provide any additional information, and my apologies if I posted this in the wrong forum area.

Hi Lalit, and thank you very much for your reply.
Unfortunately excluding space entries in selection screen wouldn't solve the issue, since we have KNA1-ADRNR for each entry, it's just that it would be different for customers found in KNB1.
I could probably solve this by making two separate queries and working on them in excel and that way we would have the necessary information.
But in order to do this in SAP seems to mean that I have to write a custom report. For that, it seems I'll be spending New Year's eve learning how to ABAP
Thank you for your help, at least we don't have to struggle with finding out a way to do this via queries so we'll just find alternative means for this.
Thanks again and have a happy new year!

Logging query with information about ip client machine address

Halo,
One of our most important requirements is logging user query (physical to database and logical) with following informations:
- USER
- SQL QUERY TEXT (logical/physical)
- DATE and TIME executing query
- IP ADDRESS client machine (or name of client machine) (this is very important information)
We have following configuration:
- BI Server with Presentation Servicess on one machine (AIX)
- Web server on second machine (BEA Weblogic 9)
I've tested [USAGE_TRACKING] mechanism but thera are three problems with it:
1. in S_NQ_ACCT in field NODE_ID is always written the same information: name of Web Server - WebLogic
2. in S_NQ_ACCT are storages only logical queries.
3. Length of field QUERY_TEXT is 1024. I'm sure that in many cases it'll be to short.
I've tested USER_LOG too (that logs to NQQuery.log file) but there are also some problems:
1. there is no information about ip client machine but is information about physical and logical queries and other necessary informations
2. oracle recommends turn off this mechanism on production system.
I've tested PRESENTATION SERVICESS log (it is configured at logconfig.xml file)
1. In file is information about ip client machine
2. In file are written only logical queries (this is big problem we also need physical queries)
Do you have some idea how to resolve my problem?
Regards

hi, you can use the sys_context function, like this:
select sys_context('userenv','current_user'),
     sys_context('userenv','os_user'),
     sys_context('userenv','host'),
     sys_context('userenv','ip_address'),
     sys_context('userenv','instance'),
     sys_context('userenv','sessionid'),
     sys_context('userenv','terminal')
from dual;
Is this what you 're looking for?

How to query Database with Parameters and configure null value response?

Hi,
1.When capture attributes from forms & after applying several logics, passing to a DB table using an API, how to get relevant values for a given parameter in another DB table ?
2.When a DB table is queried, if the value does not exist, how to configure the response message ?
Thanks.

Okay, you've provided exactly what John S. asked for - and no more. This is helpful, but not enough. I think we're going to need a use case to understand exactly what you are asking. What should the user see? What does the user do next? What should happen in the database and in the application when the user does this?
However, I'll try to read between the lines a bit, and get you part of the way there. To query the database with parameters in ADF BC, you need a View Object (VO). The simplest thing to do is create the SELECT command behind the VO with some bind variables and add the bind variables to your VO. At that point, you will get an ExecuteWithParameters operation in the Data Control. You can drag that operation onto a JSF page and it will give you an option to create a parameter form to let the user fill in the parameters to set the bind variables, and a button to execute the query with these values. Any table or form based on that same VO will show the selected data.
A Trinidad or ADF Rich Faces table will have an attribute to let you define some text to show the user if no data was retrieved by the query. But there are other ways to determine if data was retrieved which you can use to control other ways to display this information. For instance, I have a page that has an outputText component that has a "rendered" attribute to show the text only when there was no data retrieved by a query.

QUESTION: HOW TO WRITE QUERY WITH MANY TO MANY RELATIONSHIPS

Could someone help me out here?
I was sitting here looking at some tables ie table_name and synonyms and wondering.
If a table can belong to many synonyms and a synonym can belong to many tables how would one write a query where I would like to know which tables belong to each synonym or on the other hand which synonym belongs to what tables?
Would I try to develop an outside join for this, a corrolated query or a query with a subquery or would there be another format that would work better?
What would be the best method of attack on this?
Thanks for your thoughts on this.
al

Actually, the relationship is not many to many. A table can have many synonyms, but a synonym within a namespace (i.e. a PUBLIC synonym, or a private synonym created by a user) can only point to one table. The xxx_synonmys tables already contain the information about the table_name and table_owner.

RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE

제품 : RMAN

RMAN9I HOW TO RESTORE ARCHIVE LOGS WITH LIMITED DISK SPACE
==========================================================
PURPOSE
이 자료는 Oracle 9.2 이상의 RMAN에서 사용 가능한 MAXSIZE 기능에 대하여
설명할 것이다.
How to restore archive logs with limited disk space
Old Backup을 사용하여 RMAN으로 database를 recvoery할때, 모든 archived
redo logfile들을 Restore할 destination의 disk space가 모자란 경우를 종종 만난다.
이러한 경우 여러 개의 restore and recovery job으로 나누어 수행한다.
즉, 첫 번째 restore and recovery job이 끝나면 archived redo logfile들을 지우고
다음 적용될 것들을 restore한다. 그리고 다시 Recovery를 수행한다. 이러한 작업을
원하는 시점까지 recovery를 하기위해 반복적으로 수행한다.
Oracle 9iR2(9.2.0.x)부터 RMAN은 MAXSIZE option을 제공하는데 이것은 archive log
file이 restore될 disk의 space를 control할 수 있게 해 준다.
만약 disk space가 매우 제한적이라면, 즉 예를 들어 모든 archive log의 size 합보다
disk free space가 적다면 MAXSIZE option을 사용하는 것은 매우 유용하다.
이 OPTION이 기술되면 RMAN은 Media Manager에게 disk space 크기에 부합하는 만큼만
archive log들을 restore하도록 한다. 부가적인 restore operation들은 restore된
마지막 archive log가 적용될 때마다 발생한다.
MAXSIZE option은 이러한 작업들을 하나의 rman job으로 처리하게 해 주고
실수를 하지 않게 해 준다.
아래는 MAXSIZE를 설명하기 위한 예제이며 총 6 단계로 구성되어 있다.
STEP 1: Add data to the database to enforce log switches
STEP 2: Backup the database and archive logs and delete the logs
STEP 3: Add additional data to enforce new log switches
STEP 4: Remove the data file and simulate a database crash
STEP 5: Restore the data file from the backup
STEP 6: Recover the database using MAXSIZE
위 예제는 Unix와 Windows 모두에 적용될 수 있다.
STEP 6 는 다음과 같은 조건으로 두 번 수행될 것이다.
1) MAXSIZE가 archive log size보다 작은 경우:
이 경우 RMAN-6558 Error message를 만나게 된다.
그러므로 MAXSIZE를 archive log보다는 크게 설정해야한다.
2) MAXSIZE가 archive log size보다 큰 경우:
예를 들어 여러 개의 archive log를 포함할 수 있을 정도로 크게 설정하면
restore/recovery는 user에게 transparent하게 수행되어진다.
즉 archive log들은 restore된 후 applied되고 deleted되어 진다. 다시 새로운
archive log들이 restore되어지고 applied된 후 deleted 되어 진다. 이러한 작업은
recovery가 끝날 때까지 반복되어진다. 이러한 작업들이 진행되는 동안 RMAN은
아무런 Message도 발생시키지 않는다.
# Step 1: INSERT enough new data to generate log switches
create table rman_tst (col1 varchar2 (10));
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 2: BACKUP the database and the archive logs automatically
# and then delete the input
run {
backup database format='/web01/usupport/krosenme/admin/backups/db_%d%s%t'
plus archivelog format='/web01/usupport/krosenme/admin/backups/arch_%d%s%t'
delete input;
# Step 3: INSERT enough new data to generate new log switches
begin
for i in 1..30000 loop
insert into rman_tst values(i,'test');
commit;
end loop;
end;
# Step 4: REMOVE users01.dbf file and crash the database
mv users01.dbf users01.org
shutdown abort
# Restore is now needed as the data file is deleted. The backup was
# taken before the new data was added to it, thus archive logs are
# needed to bring the database up to date
# Step 5: RESTORE the data file from the full backup
run {
restore datafile '/web01/usupport/krosenme/oradata/kro_920/users01.dbf';
# Step 6: RECOVER
run {
recover database delete archivelog maxsize 10 K;
# This will fail with RMAN-6558 as the archived log has a size of 16 KB,
# which is bigger than MAXSIZE limit of 10 KB. So the error is expected
# and MAXSIZE works as designed.
# Now rerunning STEP 6: but with MAXSIZE 50 K
run {
recover database delete archivelog maxsize 50 K;

cold backup means offline backup, you shut database normally and copy datafiles to another location.
i think operating system does not matter that much but it is RedHat Linux Enterprise Server.
backing up archivelogs whith rman script which is:
run {
allocate channel c1 type disk format '$BKUPLOC/arch_%d_%u_%s_%p.bkp';
change archivelog all validate;
sql 'ALTER SYSTEM ARCHIVE LOG CURRENT';
backup archivelog time between 'SYSDATE - (30*60/(60*60*24))' and 'sysdate';
release channel c1;
so here is the details.
1. because everything is lost, we restored all files(datafiles, controlfiles, redologs etc) from offline backup meaning copied all files from another location to corresponding location.
2. want to apply archive logs which were created after cold backup till disk failure and we have these archive logs with backups which were taken by rman.
So
first of all, we want to register these archive log rman backups(because these backup information does not exist in restored controlfile)
and then restore them and then apply them.
we need rman commands to register these backups and restore them.

How to create an ABAP Query with OR logical expression in the select-where

Hi,
In trying to create an ABAP query with parameters. So it will select data where fields are equal to the parameters entered. The default logical expression is SELECT.. WHERE... AND.. However I want to have an OR logical expression instead of AND.. how can I attain this??
Please help me on this.. Points will be rewarded.
Thanks a lot.

Question Man

Hi Bhupal, Shanthi, and Saipriya,
Thanks for your replies. But that didn't answer my question.
Bhupal,
You cannot just replace AND with OR in an ABAP QUERY. ABAP QUERY is a self generated SAP code. You'll just declare the tables, input parameters and output fields to be displayed and it will create a SAP standard code. If you'll try to change the code and replace the AND with OR in the SAP standard code, the system will require you to enter access key/object key for that particular query.
Shanthi,
Yes, that is exactly what need to have. I need to retireve DATA whenever one of the conditions was satisfied.
Saipriya,
Like what I have said, this is a standard SAP code so we can't do your suggestion.
I have already tried to insert a code in the ABAP query (there's a part there wherein you can have extra code) but that didn't work. Can anybody help me on this.
Thanks a lot.
Points will be rewarded.

Query with bind variable, how can use it in managed bean ?

Hi
I create query with bind variable (BindControlTextValue), this query return description of value that i set in BindControlTextValue variable, how can i use this query in managed bean? I need to set this value in String parameter in managed bean.
Thanks

Put the query in a VO and execute it the usual way.
If you need to, you can write a parameterized method in VOImpl that executes the VO query with the parameter and then call that method from the UI (as a methodAction binding) either through the managed bean or via a direct button click on the page.

I recently updated my new iPhone by plugging it in to my laptop. However, it erased all of the texts, contacts and pictures associated with my phone prior to the update. How do I get that information back?

I owned an iPhone 4s a year ago before I unfortunately lost it. I have since then bought the iPhone 5 but had not plugged it in to my computer yet to download any music. I plugged in my iPhone today to my laptop and my iTunes store stated that it registered that it was a new iPhone and asked if I wanted to restore or update my new iPhone with the information that was backed up on my old one. I chose yes, that I did want to restore the old information in to my new iPhone. However, now that I did that, my new iPhone does not have any of the contacts, texts or pictures that I had already on my new iPhone.
I desperately want my information back that was lost on my new iPhone when I updated the phone. Is there any way to get those pictures and information back? I logged in to my iCloud account and it still did not help get my pictures, contacts or texts back.

BarnsleyMif wrote:

No such thing has occurred. iPhones do not backup to one another.
It is not possible to backup a different iPhone from the one being updated.
If the iPhone was restored with a backup from a different device, restore it again from the correct backup.

Pay attention when restoring the iPhone and select the correct backup to restore from.
