• Align the text of the varchar2 column data

  Hello
  
  It is in reference below thread:
  Re: Align the text of varchar2
  
  I think I should post my question in this forum, rather than General database,
  
  I created a table and inserted the same that in the thread that above, and when I said:
  Select ID, FILLED_TEXT(DESCRIPTION,30) FROM T;
  
  It does not show the data in the column as aligned in 30 word boundaries. I thought, that I would be able to resolve the issue with the help of the http://soft.buaa.edu.cn/oracle/bookshelf/Oreilly/prog2/ch11_02.htm link, but failed.
  
  Kindly help me more.
  
  Kind regards.

  Okay, so you're saying there is already a tags in the code to indicate where the line breaks are necessary, so a small adjustment of the data to include these tags and also the code...

• Need to convert the Varchar2 column number for the extraction of data based on the range of values.

  Hello

  I have a ZIP column which is the Varchar2 data type, it has values such as 2345, 09485, 10900, 07110, 06534.

  I have to go look up records from the range of values for the ZIP column as between 00000 and 07500.

  Could you give a logic.

  Thank you.

  Hello

  I think you can use the following code:

  SELECT T.*

  OF t

  WHERE the to_number (ZIP) between TO_NUMBER('0000') and TO_NUMBER('07500')

• How to set the time of data collection for information Publisher report

  Hello everyone,

  So, I'm trying to set up a report, which contains some information of tablespace. The report must be sent to my e-mail account around 07:00 every day, so I have an overview if we run into a few problems with some full tablespaces. the report and mail notification works well but my only problem is, the data are not updated. There is a comment under each data table in my report which said that the data had been updated on 8 to 13 hours ago according to the target database. is there a way I can trigger the update of data report on a specific time? So I can update the data before you run the report job every morning around 07:00? I'm totally noob, so I hope someone can help me, I tried to google it but I couldn't find anything useful.

  Unfortunately, there is really no good way to 'schedule' collection for this because it is perceived with a dozen of other data points and likely to cause problems.   What you could do, is create a metric custom extension with query data file you need (simple Dungeon it do not go beyond what you really need to prevent performance problems), deploy the metric on all target databases, then disable collection of gui (metrics and collection parameters) and cron the collection to run at a period determined using emctl control agent runCollection : .   You can then create a report about the data collected in mgmt$ metric_current.

• What is the difference between the "Received" column &amp; "Date"?

  The entries in the columns of "Receipt" and "Date" of the re CT should be the same; When they differ, it is no more than a few minutes. I wonder, that these columns show exactly? Why do these two categories? It obviously has something to do with the header lines, but I could not find it.

  one is the date of the sending of the message, the other the arrival time. Usually it is only a minute or two different these days, hours were not uncommon in the past and even now, Google, will try and deliver a week. If your server down lovers and it takes 5 days to fix or the submarine cable is blown, you will get the google mail which takes days in the date but also fresh column like today in the received.

  I have only the date. By clicking on the right-hand column headings allow you to customize the columns are displayed

• ODI 12 - problem with missing data in the store column data types

  Hello world

  We have recently installed Studio 12 on Oracle RDBMS ODI. We have created some topologies, contexts and the logical architecture. We have created the necessary templates and made reverse engineering. The strange thing is when a model data store opening, we have noticed, the data types of its attributes are not displayed and cannot be selected in the drop-down list because they do not exist yet. You can see the image below.

  

  So the mappings are not correctly executed because on the stage of the creation of work tables CREATE script was not generated correctly. (It's something like "CREATE TABLE < name > ()")

  Anyone can give an idea what could be the reason for this and how might be solved?

  Any ideas would be appreciated.

  The data type of an expression of DECODE() is determined by that of his first return value. Oracle has decided that a NULL value is a VARCHAR2 data type (because there must be something ).

  The changes to your code are extremely intertwined and twisted out and frankly too hard to work through. However, I think at some point the changes that you have implemented it had that effect.

• Need for clarification to varchar2 column

  I get xml that will be inserted in the local table messages
  It is, I don't really know the size of the incoming xml message data.
  Design of the structure of the table is now difficult.
  If I design the column in the table for column varchar2 with VARCHAR2 (4000) and if the message contains the value
  as 'SAM', 'GEORGE' (no more than 10 characters) then it does not seem good for the VARCHAR2 COLUMN (4000)
  Oracle does not create the table with VARCHAR2 (without specifying the size)

  Any suggestions?

  S

  There's no real difference if you use varchar2 (4000) or varchar2 (100). Apart from the obvious that you can store up to 4000 bytes, against only 100/characters multibyte.

  However, there are a few minor side effects. Few of them and a comparison of the performance is described here: http://arjudba.blogspot.de/2009/08/does-oversize-of-datatype-varchar2.html

  (1) the varchar2 column indexing 4000 could be a problem (the ora-01450 exceeded max key length).

  (2) the size of the table could be actually smaller for tables with many sparesly populated varchar2 4000 columns. I can't find the source for that at the moment, but it had to do with the way oracle reserves future space required for the column.

  (3) migration of rank is more likely to happen if the great texts are added (= update) later.

  (4) If you define a variable with % rowtype in the table, it will use more expensive space PGA

  (5) some tools like TOAD could get questions or need of more resources to operate on 4 k columns.

• How to read the two columns of data from the Port series

  Hello

  I'm reading two columns of data from the serial port.

  I want to both sets of chart data.

  I enclose my VI.

  Thank you for your help.

  The analysis of string function takes a "Format string" on top (with the right button of the function and choose Help, which explains all the entries).  In particular, you can say 'Give me two numbers separated by a tab' and the output will be two numbers (whole or floating, depending on the chosen format).  In particular, %d\t%d specifies a decimal integer, , whole decimal.

  Thank you.

  Specification of column names is required, but you can omit the declaration of data types.

  See: the function XMLTABLE SQL/XML in Oracle XML DB

  XMLTable is used with storage XML based on a schema of XMLType data type is optional. If absent, the data type is inferred from the XML schema. If Oracle > XML DB is unable to determine the right type of a node, a default type VARCHAR2 (4000) is used.

  It is an Oracle extension; in the SQL/XML standard, the data type is always required.

  Note:
  The alleged data type might change as a result of the application of a patch or upgrade of Oracle XML DB. In particular, a new set of release or patch might be able to > determine the data type when the previous version was unable to do so (and therefore not reimbursed to VARCHAR2 (4000)). To protect against such an eventuality, specify an explicit data type with the data type.
