Help needed in SQL performance - Using CASE in SQL statement versus 2 query
Hi,
I have a requirement to find count from a bunch of tables.
The SQL I have gives the count of all members.
I have created 2 queries to find count of active and inactive members.
The key difference is only the active dates.
Each query takes 20 seconds to execute.
I modified the SQL to use CASE statement in the SELECT.
So after the data is fetched the CASE statement will evaluate the active date and gives 2 counts (active and inactive)
Is it advisable to use this approach. Will CASE improve SQL performance ? I have to justify this.
Please let me know your thoughts.
Thanks,
J
Hi,
If it can be done in single SQL do it in single SQL.
You said:
Will CASE improve SQL performance There can be both cases to prove if the performance is better or worse.
In your case you should tell us how it is.

SQL>HELP is appreciated as to where I am going wrong?Hi,
if you want to transform something to something else, you should declare, what is your source.
I would prefer to use plain XSL-Transformations, because you have a lot more options to transform your source and you can even better determine, how your output should looks like.
Kind regards,

Query help needed for querybuilder to use with lcm cli
Hi,
I had set up several queries to run with the lcm cli in order to back up personal folders, inboxes, etc. to lcmbiar files to use as backups. I have seen a few posts that are similar, but I have a specific question/concern.
I just recently had to reference one of these back ups only to find it was incomplete. Does the query used by the lcm cli also only pull the first 1000 rows? Is there a way to change this limit somwhere?
Also, since when importing this lcmbiar file for something 'generic' like 'all personal folders', pulls in WAY too much stuff, is there a better way to limit this? I am open to suggestions, but it would almost be better if I could create individual lcmbiar output files on a per user basis. This way, when/if I need to restore someone's personal folder contents, for example, I could find them by username and import just that lcmbiar file, as opposed to all 3000 of our users. I am not quite sure how to accomplish this...
Currently, with my limited windows scripting knowledge, I have set up a bat script to run each morning, that creates a 'runtime' properties file from a template, such that the lcmbiar file gets named uniquely for that day and its content. Then I call the lcm_cli using the proper command. The query within the properties file is currently very straightforward - select * from CI_INFOOBJECTS WHERE SI_ANCESTOR = 18.
To do what I want to do...
1) I'd first need a current list of usernames in a text file, that could be read (?) in and parsed to single out each user (remember we are talking about 3000) - not sure the best way to get this.
2) Then instead of just updating the the lcmbiar file name with a unique name as I do currently, I would also update the query (which would be different altogether): SELECT * from CI_INFOOBJECTS where SI_OWNER = '<username>' AND SI_ANCESTOR = 18.
In theory, that would grab everything owned by that user in their personal folder - right? and write it to its own lcmbiar file to a location I specify.
I just think chunking something like this is more effective and BO has no built in back up capability that already does this. We are on BO 4.0 SP7 right now, move to 4.1 SP4 over the summer.
Any thoughts on this would be much appreciated.
thanks,
MissyJust wanted to pass along that SAP Support pointed me to KBA 1969259 which had some good example queries in it (they were helping me with a concern I had over the lcmbiar file output, not with query design). I was able to tweak one of the sample queries in this KBA to give me more of what I was after...
SELECT TOP 10000 static, relationships, SI_PARENT_FOLDER_CUID, SI_OWNER, SI_PATH FROM CI_INFOOBJECTS,CI_APPOBJECTS,CI_SYSTEMOBJECTS WHERE (DESCENDENTS ("si_name='Folder Hierarchy'","si_name='<username>'"))
This exports inboxes, personal folders, categories, and roles, which is more than I was after, but still necessary to back up.. so in a way, it is actually better because I have one lcmbiar file per user - contains all their 'personal' objects.
So between narrowing down my set of users to only those who actually have saved things to their personal folder and now having a query that actually returns what I expect it to return, along with the help below for a job to clean up these excessive amounts of promotion jobs I am now creating... I am all set!
Hopefully this can help someone else too!
Thanks,

Thanks
RamRam,
I have had printing problems too a year and a half ago. I used all printing apis of java and I still find that it is something java lacks. Now basically you can try autosense. To check whether your printer is capable of printing the docflavor use this PrintServiceLookup.lookupPrintServices(flavor, aset); . If it lists the printer then he can print the document otherwise he can't. I guess that is why you get the error.

Charactersitic values to be used in IFTHEN ELSE STATEMENT IN QUERY
scenario: i need to use the characteristic values(not the attributes) to be used in an IF THEN ELSE STATEMENT in query. so i created a formula variable for the characteritic of processing type replacement path, replace with key.The values are not fetched in the result and is displayed as X.
what should i replace with key,lable, constant or other options whereas my requirement is the all the values present in the characteristc should be used.
eg. if char name is xyz and has the values 1,2,3,4,5 till -
20.
then in a calculated key figure :(formulavariable =1)* kefig1keyfig2 +not(formulavariable =1)kef2keyfig3.
this formula variable should have all the values of the characteristic values ie 1,2,3---20.
2. how should i do get the values of characterstics values in the equation give me the steps in detail..
3. i do not want to use the attributes, though i tried initally while creating the formual variable i replaced with attribute value, there is was an error and there were no reult.
i tried to create char. variable for the characteristic of manual entr , not ready for input values and gave all the values 1,2,3 --20 as default values and then created formaul variable and repalce with the variable, however this characteristic variable is not at all displayed from the list of variables which will be displayed while creating the formula variable.
help me out.
Thankshi srini,
i have includedthe char in rows. i want you to explain in detail how to use these values in the if then else statement in query.
i have created a calculated key figure 2= (formual variable =1 & keyfig a =0)* keyfig1kefig2 +not(formual variable =1 & keyfig a =0)keyfig2 *calculated keyfig1.
so this formula variable of replacement path have ref. to then char. and with what value should it replace, key, name, external char or attribut etc so that i should get the values of the char from 1 to20.
i donot to repalce with the attribute. i just want the char. values and not thier attributes (1. description 2. the second attribute has the values say abc1,efg2,ghi3 for respective charteristic values.
ie
char value desc 2nd attrib
1 hi abc1
2 bye defg2

Help needed - Planning Server 2012 solution, DC/Exchange/SQL/RDP host/Remote apps etc
Hi All,
I have a client needing me to provide a Windows server based solution for their business. I have limited experience with Server 2012, although I have worked with 2008R2 and SBS2011, I am needing some guidance with this 2012 project.
The client has about 8-10 local users who work at one office with an NBN connection, and 2 other locations that have 3-5 users at each location. I am needing to provide them with a server based solution to manage their data, remote access and also their
email. They are also likely to expand to another physical office soon.
I need to provide them with a DC controller, Exchange server and possibly an SQL server in the future. They currently use an Act database, but I have been told that once the database in ACT grows to 4G, a dedicated database is required?
I am currently thinking of having one physical server and virtualising the additional servers on this platform, however I come from a UNIX background and have not virtualised using Hyper V or ESXi before. I have read a little regarding the CLI and GUI Hyper
V options, but I really need advice on what will suit my needs best from someone that has done it.
I am thinking I maybe should recommend one physical machine with Server 2012 Std which, from what I understand, will allow me to install the host hyper V host on the physical machine and then I could possibly install an instance of Server 2012 as
the DC, Exchange and SQL server on one VM licence, however I have read it is not preferred to have the exchange server on the same VM as the DC but have read that limiting the memory usage of Exchange can negate these issues?
I will also need to have a terminal server/RDP session host in there as well which I could maybe use the 2nd VM licence for.
I suppose my question is, considering that I need to end up with a DC, Exchange server, terminal server/RDP session host and possibly a SQL server in the future, am I better off virtualising and running these on a Server 2012 Std licence, that allows a hyper
v host + 2xVM's or should I be splitting these roles up on different physical machines, keeping in mind costs need to be kept to a minimum.
Also I need to consider the Microsoft Office side of things. Is it more financially viable to use office licences and use remote apps from the terminal server, or just purchase Office H&B for the workstations/laptops and have their outlook connected
directly to the exchange server?
I am concerned from the performance viewpoint that if I run the DC/Exchange and SQL from one VM, then the TS/RDP Host from the other VM licence it may be too much for the DC/Exchange/SQL VM to handle.
I have used SBS 2011 in a few locations with Exchange and the SQL and DC roles installed on HP DL and ML gen 8 servers, and although they run a little slow on the console, they seem to serve the network clients fine.
If do end up running on one physical machine the Hyper V host, one VM as a DC, Exchange and SQL server, and the other VM licence as a RDP session host, what sort of spec'd machine would be recommended to be able to do this, keeping in mind
I usually lean towards HP servers.
Anyhow, thx in advance and any comments or suggestions will certainly be appreciated.
MkmHello,
sorry but in your case without the knowledge of all major requirements i would suggest that you or your client contact an expert and not work with the forums to get this amount of information and setup requirements.
Exchange on DCs is NOT recommended, even not from Microsoft. Also it is highly recommended to run at least 2 DC/DNS/GC per domain for failover and redundancy, of course NOT on the same physical machine.
RDS servers should also run on dedicated machines and not be used for anything else.
SQL should also run on a separate server.
You cannot compare SBS version with regular server versions, the concept behind is different.
With that small amount of users you should consider using an Office365 solution where you could use a plan that fits your needs and have just computers for your client employees.
But as stated above therefore you should find an experienced consultant.

Help needed with condition based joins in pl\sql
Hi,
I need to get data from 6 tables,
Scenario 1 : I need to join 4 tables and join this result set to 5th table
Scenario2: resultset of join of 4 tables to 6th table
In this case how do i save the intermediate result set of 4 tables to use it in further joins.Welcome to the forum.
Your question is broad.
http://tkyte.blogspot.com/2005/06/how-to-ask-questions.html
A more detailed example would help.
Mention your database version as well and see the FAQ http://forums.oracle.com/forums/help.jspa when it comes to posting formatted examples using the {noformat}{noformat} tag
However, i think using the WITH clause or a subquery ( a.k.a. inline view) is what you're looking for.
Do some searches on http://asktom.oracle.com to find many examples.

Help needed in business logic implmentation in oracle sql.
I got a requirement from customer that i need to generated numbers based on first value which is entered by users but not second values..
for example:
c1 c2
1 1
2 1
3 1
4 1
1 2
2 2
3 2
4 2
1 3

2 5
3 5
4 5
unlimited..
the user input only first column values which comes from UI and i need to provide second column values when records are getting inserted into db table.
user always enter only 1-4 values in first column but never input second values in second column of table.. both columns are numerical.
the second values should be provided automatically or programmatically when records are getting inserted into table and automatically... how this can be done?
Can any one help me out to get this done either using sql,plsql concept?
thanks a lot in advance.Hi,

Request some help, over procedure's performance uses regular expressions for its functinality
Hi All,
Below is the procedure, having functionalities of populating two tables. For first table, its a simple insertion process but for second table, we need to break the soruce record as per business requirement and then insert into the table. [Have used regular expressions for that]
Procedure works fine but it takes around 23 mins for processing 1mm of rows.
Since this procedure would be used, parallely by different ETL processes, so append hint is not recommended.
Is there any ways to improve its performance, or any suggestion if my approach is not optimized? Thanks for all help in advance.

Many Thanks,
ArpitRegex's are known to be CPU intensive specially when dealing with large number of rows.
If you have to reduce the processing time, you need to tune the Select statements.
One suggested change could be to change the following query
SELECT
REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,t2.COLUMN_VALUE) str
FROM
DUAL t1 CROSS JOIN
TABLE
CAST
MULTISET
SELECT LEVEL
FROM DUAL
CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
AS SYS.odciNumberList
) t2
to
SELECT REGEXP_SUBSTR(P_EXCEPTION_RECORD, '([^^])+', 1,level) str
FROM DUAL
CONNECT BY LEVEL <= REGEXP_COUNT(P_EXCEPTION_RECORD, '([^^])+')
Before looking for any performance benefit, you need to ensure that this does not change your output.
How many substrings are you expecting in the P_EXCEPTION_RECORD? If less than 5, it will be better to opt for SUBSTR and INSTR combination as it might work well with the number of records you are working with. Only trouble is, you will have to write different SUBSTR and INSTR statements for each column to be fetched.
How are you calling this procedure? Is it not possible to work with Collections? Delimited strings are not a very good option as it requires splitting of the data every time you need to refer to. -
Help needed for file processing using FTP
Hi All,
I am new to ODI tool and currently we are implementing one project in ODI. Could you please, any one help me on the following requirement... how to implement it?
Scenario:
i) I need to pick a file from remote host 'outbox' dir using FTP process, and place into local 'temp' dir. (I can do it with odiFTPGet tool)
ii) Change the file as per target business requirement.??? ( this step challenging me)
for ex:
if source file name : <project name>_<source ID>_<transaction name>_<unique id>.txt
target name should be : 1234_<transaction name>_<sysdate in yyyyMMddhhmmss>_<unique id>_2345.txt ( here 1234 and 2345 are hard coded values)
iii) Later move to local 'temp' to local 'outbox' dir. ( I can do it with odiFileMove tool)
iv) After successful process move the file from remote 'outbox' to remote 'archive' dir ??? (again this is challenging me).
For this my questions are:
1) How to get file name into a variable ( In one of the post , it says we need to create data model and data stores, and interface to get the file names into a file. apart from is there any easy way i can implement it in package it self?)
2) How to tokenize a long string ( i.e., need to tokenize the source file to get <unique id> and <transaction name> and map to target file name)
3) How to define implementation for Java in user function?? do we need to use class declarations and import statements?? I need a sample user function in Java.
4) How to move/rename a file in remote server?? ( need to move file from remote 'outbox' server to remote archive' dir)
5) If any step in package fails, How to get the error msg into a variable which i can use for sending mail and raise a ticket in remedy?? ( I will pass that variable to as content to mail and remedy ticket)
6) How to handle list type data (string list) by variables in ODI?? (As we can define single variable not as list.)
I am sorry to ask all my queries I a single post. But I need to solutions for all to implement this in my project.
Thanks in advance. Appreciate early response.

Kiran.NCan any one share your thoughts for my request.
Thanks in advance.
