• Select previous date table

  Hi all
  
  My need is to choose the present previous date in the table. For example, I select '' 2012-03-30 in my first article, Sun' 2011-12-30' should be in the second column. How can I make it?
  

  with t1 as (
  select date '2012-03-30' as arcdate from dual union all
  select date '2011-12-30' as arcdate from dual union all
  select date '2011-09-30' as arcdate from dual union all
  select date '2011-06-30' as arcdate from dual union all
  select date '2011-03-31' as arcdate from dual union all 
  select date '2010-12-31' as arcdate from dual 
                 )
  select arcdate, '' as previous_date_from_table  
  from t1 
  where arcdate = date '2012-03-30' 

  Hello

  Use analytics LAG fucntion, like this:

  WITH    got_prev  AS
  (
       SELECT  arcdate
       ,      LAG (arcdate) OVER (ORDER BY arcdate)     AS previous_date_from_table
       FROM      t1
  )
  SELECT     arcdate
  ,     previous_date_from_table
  FROM     got_prev
  WHERE      arcdate     = DATE '2012-03-30'
  ;
  

  Analytical functions are calculated after the clause WHERE is applied; This is why a subquery is needed here. If we use the same query as the LAG

  WHERE      arcdate     = DATE '2012-03-30'
  

  then the result set will that one line, and LAG returns NULL.

• user input windows OS when loading data using sql loader

  Hello
  I have the oracle 11g Linux database.
  I have excel sheets with data that must be loaded into the database.
  I have oracle running on my windows client11g.
  
  When I or anyone else is running the load sql script to load the data, I need to capture the user OS (the one that runs the script of their windows login) and pass it via the sql loader and insert into the table as a column value outside the columns in the excel sheet.
  
  I think that this could be a very simple solution, I did some research but not just anywhere.
  Can someone guide me on this.
  
  Thanks in advance.
  Philip.

  Well, I built this example on the fly to show the answer. But it is based on documentation and previous experience with sql * loader or sys_context.

• calculation on line data

  Hello world

  I have just started using the tiara and I have no idea how I can do a few calculations, I want to have chanell with result depends on the other chanells, but not the same data line, I can use the SMC (line, no.) and I can do to make it function in a cell with my result chanell (example for the first row of data (: SMC (1, Ch("[4]/Channel1")) = (ChD (1, Ch("[4]/Channel")) + SMC (2, Ch("[4]/Channel"))) / 2), but I don't know how I can do this function automatically for the other line (for example, line 2 ChD (2, Ch("[4]/Channel1")) = (ChD (2, Ch("[4]/Channel")) + SMC (3, Ch("[4]/Channel"))) / 2) I have a line of 500,000 of data so I need know some functions that will be clalculated this function on the lines of my data. I will be grateful for your help.

  Hello!

  For performance of good calculations on your data of type long, you must use a formula in tiara. In the past, it was the FormulaCalc command. Today, the ChnCalculate is recommended. The similar oddity in the two commands, they can only do calculations on one line (it's repeat them verry fast for all lines). For you the problem this behavior results in a no aproach obvoius. You must copy your data to a second channel, remove the number of values that gives your shift and then use the two channels for the calculation. Here's the script for offset = 1:

  Call ChnCopy("[1]/Channel","[1]/ChannelCopy")
  Call DataBlDel("[1]/ChannelCopy", 1, 1)
  Call ChnCalculate("Ch(""[1]/Result"" )= Ch(""[1]/Channel"" ) + Ch(""[1]/ChannelCopy"" )/2")

• cannot restore from the previous date says computer is unprotected I just get rid of the virus of audit system

  rid of virus check system but cannot restore the computer to the previous date

  You never said how you got rid of the "System Check" malware. As far as we know, he is still there. Follow these instructions (if you have not already done so):

  http://www.bleepingcomputer.com/virus-removal/remove-system-check
  Also, as Jose pointed out, there are programs that are designed to interfere with the system restore (Norton is one of the most common). But there are really two questions. First of all, we will treat your malware problem. We can always revisit SR at a later date.
  Finally, even once as Jose pointed out, you NEVER run the system restore after the removal of the malware! Which could only bring him back! That you have to turn it off and then put it again, which will REMOVE all previous restore points. You really all gone!

  This issue is beyond the scope of this site (for consumers) and to be sure, you get the best (and fastest) reply, we have to ask either on Technet (for IT Pro) or MSDN (for developers)

• Loading data from SQL to Essbase table

  Hello

  I'm loading data from SQL to Essbase table by using a rules file. Number of rows in the source table is 7 million. I use the SUNOPSIS MEMORY ENGINE as area transit, LKM SQL for SQL and SQL IKM for Hyperion Essbase (DATA).

  Question:

  1 can I not use any other LKM as MSSQL for MSSQL (PCBS) to load data to the staging instead of LKM SQL for SQL? What I have to change the transit area then? Loading data using LKM SQL for SQL seems quite slow.

  2 it is mandatory to use LKM SQL for SQL, can someone please tell me what I can change to make this quick support parameters?

  3. is it compulsory to use the SUNOPSIS MEMORY engine loading data from SQL server to Essbase?

  Thank you...

  (1) Yes, I highly recommend watching using a KM which uses native as database technology these will usually be more efficient than the generic (like LKM SQL for SQL) KM especially when large volumes of data are involved. Your staging will change depends on where you organize data for example if you are using a SQL server specific KM as - MSSQL for MSSQL (PCBS) - you must have a lay-by available on a MSSQL database and have access to the utility of PCBS.

  (2) it is not mandatory to use this KM you can use a KMs supported by your database technology

  (3) it is absolutely not obligatory to use the SUNOPSIS MEMORY engine. This should only be used when you have relatively small amounts of data, as well as all the processes in memory, or in the case where you have no other relational technology to perform the staging on. However, in your case to use wherever you are processesing these large volumes of data you should be staged on a physical such as SQL Server or Oracle database if they are available.

• Loads of parallel data through SQL connect and replace existing data

  I'm doing a load of multiple data through SQL Connect using the following statement.  Just try to put in place a .bat file to automate the process but not sure that whenever it executes this statement adds data to existing or replaces the data? I tried to write an override for this but it works for instructions which contain the import section.

  Import of database data App.DB connect as username identified by password

  with the help of several rules_file, rul1, rul2, rul3

  load_buffer_block starting with buffer_id 10 on error write to 'C:\\dataload.err ';

  We can add spec commit buffer such as "replace all data ', 'create group', 'Add' to this import statement? The default declaration overrides the value whenever the data is loaded?

  Thanks in advance!

  you have an option in the rules file "Overwrite out of values."

• view the data in SQL

  I was able to use ASP to retrieve data from SQL database by using something like the one below:

  SQL = "SELECT PageName",

  SQL = SQL & "CONVERT (NUMERIC (6,2), AVG(Rating * 1.00))" AVERAGE ".

  SQL = SQL & 'COUNT (Rating) AS Total',

  SQL = SQL & "SUM(CASE WHEN Rating = 1 THEN 1 ELSE 0 END) AS [Star1Total]"

  SQL = SQL & "SUM(CASE WHEN Rating = 2 THEN 1 ELSE 0 END) AS [Star2Total]"

  SQL = SQL & "SUM(CASE WHEN Rating = 3 THEN 1 ELSE 0 END) AS [Star3Total]"

  SQL = SQL & "SUM(CASE WHEN Rating = 4 THEN 1 ELSE 0 END) AS [Star4Total]"

  SQL = SQL & "SUM(CASE WHEN Rating = 5 THEN 1 ELSE 0 END) AS [Star5Total].

  SQL = SQL & "FROM [SDBI]. [dbo]. [GnieRatePage] "

  SQL = SQL & "GROUP BY PageName".

  SQL = SQL & "ORDER BY PageName".

  I then post on the help page:

  Response.Write ("PageName") Recordset

  What I need, it of to transmit these data to Flash and let Flash to view the coast. How to do by way of ASP?

  Thank you

  I don't use the proper syntax for writing couples variable/value with asp, but, if this is the case, use:

  var myTextLoader:URLLoader = new URLLoader();

  myTextLoader.dataFormat = pouvez;

  myTextLoader.addEventListener (Event.COMPLETE, onLoaded);

  function onLoaded(e:Event):void

  {

  for {(var s:String in e.target.data)

  trace (s, e.Target.Data [s]);

  }

  myTextLoader.load (new URLRequest ("read_page_rating.asp"));

• data via sql dev store

  Hello
  I've given cluster and can store files and it is clustering ID in the new database using the ODM. I group these data via SQL dev. Oracle again but I'm not for any folder for the storage of cluster ID. How do I? can I put something in response or detail node?

  Hi Nasiri,
  In your description, you have only the Cluster node as entry in the node to apply it. You should also connect a node type of source of data as well. Just to get this to work, why not connect the source of input data to your Cluster node to the node to apply it. If the node to apply it should have 2 inputs, a node of type of data source, but also a model node.
  Thank you, Mark

• How only migrate data between SQL Server 2008 Oracle 11?

  According to our requirement, we only have to migrate data from a SQL Server database to an existence
  Oracle database user.
  (1) I tried to do with the wizard of Migration SQL Developer 3.0.04, but find a problem.
  My SQL Server database name is SCDS41P2 and my Oracle database user name is CDS41P2;
  When I used SQL Developer move offline data by the Migration Wizard, I found all the oracle user
  name in movedata files who obtained by running the Migration Wizard
  is dbo_SCDS41P2. If the Oracle user name is not the same as my Oracle username existed.
  the data cannot be moved to my user Oracle existed when I run oracle_ctl.bat in the command line window.
  So I had to change the Oracle username in all the movedata files, but it is difficult to change because there are a lot of tables in
  databases. So could you please tell me how to get the movedata files which is the name of user oracle in them my
  WHEREAS Oracle user name?
  
  (2) I also tried to use the "copy to Oracle" to copy the data to SQL Server database tables
  the user database was Oracle. When you click on 'copy to Oracle', I selected the option 'Include data' and 'replace '.
  But I found some tables cannot be copied, the error info is as below:
  SPSSCMOR_CONTROLTABLE table failed. Message: ORA-00955: name is already used by an existing object
  
  Could you please tell me how to deal with this kind of mistake?
  
  Thank you!

  Hello
  After following with development the following should work too-

  1 use the migration option to capture and convert the SQL * database server
  2. go in SQL * Developer and remove the converted model.
  3. click on the captured model and choose 'convert '.
  4. click Next and you should get a screen with 2 options - "Data Type Mapping" and "Object Naming.
  5. choose "Object Naming" and scroll down the list until you see the name of the user who will be transformed. For example, in my test, I got the names scott_test and dbo_test - where the owners are 'scott' and 'dba' and 'test' was the name of the database.
  6. change the name of oner_database to just owner - scott_test to scott
  7 complete the conversion process and the owners must be created without the name of the database.
  8. you should now be able to generate the SQL * scripts of charger with only the name of the owner in the CTL files.

  Please try this and let us know if it works for you.

  Kind regards
  Mike
