Regular expression to extract the date

• Use regular expressions to extract .llb file from the path name

  I'm trying to be smart (always a dangerous thing) and use a regular expression to extract the name of a library to a filepath converted to a string.   While I appreciate there are other ways to do this, regex seems to be a very powerful way of neat, I would be able to operate.

  IE, if I have a string of type, C:\applications\versions\library.llb\toplevel.vi, I want to be able to extract the library.llb of the string, because it will be of variable length, may include the numbers & spaces and may be located in a file of variable depth hierarchy.   In other words, I want to extract the part of the string between the last-which ends with .llb

  The best I managed so far is \\+.*llb who all returned less the drive letter and the toplevel.vi

  Can someone help me to achieve this goal, or I'm better by using an alternative method (for example filepath string in array, search for .llb)

  Thank you

• Foglight v6 - FaultException: impossible to extract the data of inventory of the collector

  After having modernized our virtual center to V4, the foglight fails to report all the details and only has the following alert:
  "FaultException: impossible to extract the data of inventory of the collector: the parameter name cannot be null or an empty string."
  ' Parameter name: key to make sure the collection agent service is running.

  Hi Joviyach,
  I logged a call with Vizioncore and the resolution is as follows:
  the problem you have is related to a VMware problem experienced during the upgrade to vSphere 4.0 as detailed in: kb.vmware.com/.../search.do
  Bascially, you must run a SQL command of your Virtual Center via MS SQL Management Studio that will identify one or more VMs who have a missing entry in the VPX_VIRTUAL_SCSICONTROLLER table. Once this information is determined that you would follow the steps 2 to 6 of the reolution... basically remove these virtual machines of the inventory and adding them back.
  When these steps are complete, you will re-start the vFoglight Collector of Vmware and Vmware vFoglight connector services.

  I tried the "REGEXP_SUBSTR' but my version of the database is 9i, and it is available only from 10 g.
  
  Thanks in advance.

  Hello

  You can use SUBSTR and INSTR
  This should work in Oracle 9:

  WITH     cntr     AS
  (
       SELECT     LEVEL     AS n
       FROM     dual
       CONNECT BY     LEVEL <= 3
  )
  ,     got_pos          AS
  (
       SELECT     x.txt
       ,     c.n
       ,     INSTR (x.txt, '[', 1, c.n)     AS l_pos
       ,     INSTR (x.txt, ']', 1, c.n)     AS r_pos
       FROM           table_x  x
       CROSS JOIN    cntr     c
  )
  SELECT        txt
  ,        n
  ,        SUBSTR ( txt
                 , l_pos + 1
              , r_pos - (l_pos + 1)
                 )     AS sub_txt
  FROM        got_pos
  ORDER BY   txt
  ,             n
  ;
  

  Sorry, I don't have an Oracle 9 database now; I had to test this in Oracle 10.

  It's true. Regular expressions are very useful, but they are not available in Oracle 9 (or earlier).
  Oracle 9 has a package supplied by Oracle, OWA_PATTERN, which provides regular expression features:
  http://docs.Oracle.com/CD/B12037_01/AppDev.101/b10802/w_patt.htm
  I know it's the Oracle 10, documentation, but there are in Oracle 9, too.

  Oracle 9 is very old. You should consider the upgrade.

• Extract the data from the ReadyNAS Duo 3 to disk?

  Hello

  I have a ReadyNAS Duo chassis crashed with two drives of 3 TB in it. Both discs seem to work very well.

  How can I do to retrieve the data from disks of theses? they were in a RAID 1 configuration, so I guess I just need to extract one of the disks. Does it matter which drive is it?

  I started to connect one of the disks to an installation of Ubuntu and I can find from the disc with respect to the available partitions, but I get no info on the file system used, only that it is flagged as RAID.

  Because I don't want ot destroy all the data I was very careful when working with the partitioning tool. So far, I've installed and looked parted, gparted, gdisk and a few others.

  Since I'm really new to Linux, I need more detailed assistance with indicators to be used to access the drive.

  Any input is highly appreciated.

  m_model-> insert(data.value() .value ("data") .toMap ().value("weather").toList () .at (0) .toMap ());

  Using the above line, I am able to extract relevant data from "current_condition and"weather".

  What should I add to the line above to also extract data from 'weather_desc '?

  Any help would be appreciated. Thank you.

  Thank you! It is much easier to read when formatted, it's the first thing I did.

  To access weatherDesc in usage by time:

  Data.value.value("data").toMap ().value("weather").toList () .at (0) .toMap ().value("weatherDesc").toList () .at (0) .toMap .value ("value") ())

  This will return "Sunny."

  For readability, I suggest if this string to:

  QMap  dataMap = data.value().value("data").toMap();
  
  QList weatherList = dataMap..value("weather").toList();
  
  QVariant firstWeatherEntry = weatherList.at(0);
  
  QMap weatherEntryMap = firstWeatherEntry.toMap();
  
  QList weatherDescList =
  weatherEntryMap.value("weatherDesc").toList();
  
  QVariant firstWeatherDescEntry = weatherDescList.at(0);
  
  QMap weatherDescEntryMap = firstWeatherDescEntry.toMap();
  
  QString value = weatherDescEntryMap.value("value").toString(); // "Sunny"
  

  Also, you can check intermediate outcomes at each stage by calling

  qDebug()< weatherlist="">< "\n";="" and="" so="">

  Thank you
  a large part

  Hello

  Something like

  WHERE TO_CHAR (entrydate, "MMDD") > '0901'

  I hope that answers your question.

  If this isn't the case, please post a small example of data (CREATE TABLE and only relevant columns, INSERT statements) for all of the tables involved and also publish outcomes from these data.

  Explain, using specific examples, how you get these results from these data.

  Include special cases, you need to manage; for example, entrydate is exactly 1 September (before or after him), or entry_date is 06:00 on 1 September.

  Always say what version of Oracle you are using (for example, 11.2.0.2.0).

  See the FAQ forum: Re: 2. How can I ask a question on the forums?

• Portlet cannot extract the data

  Hello

  I created an adf application that retrieves data from the Employees table.

  I run to the local wls and everything works fine.

  I created an entry portlet.

  I have deployed my portal (right click on the application--> deploy...).

  I created a page to add my portlet here.

  I ran the page and it is impossible to extract all the data.

  From the console, I had a reference of message incomplete connection for connection object: op

  Any ideas how I can retrieve the data?

  Christos

  The first thing that the error message complains of a connection named "op" while your server has set 'opekepeDS '. Second thing, it is that jdbc, data sources are defined with a tiny "jdbc" instead of the uppercase 'JDBC' you used.

  Check the connection of the application. The name of the data source must match the name defined on the server.

• Regular expression to remove the space in the HTML tag

  Hi all

  My HTML string is as below.

  Select ' < CityName > RICHMOND < / Nom_ville >

  < StateCd > ABCD CDE

  < StateCd / >

  < CtryCd > CAN < / CtryCd >

  < CtrySubDivCd > BC < / CtrySubDivCd > ' double Str

  Output desired is

  < CityName > RICHMOND < / Nom_ville > < StateCd > ABCD CDE

  < StateCd / > < CtryCd > CAN < / CtryCd > < CtrySubDivCd > BC < / CtrySubDivCd >

  I want to remove these spaces of the tag value box with only spaces otherwise leave it as what. Please help to implement the same using regular expressions.

  Hello

  We don't know what you want.  This site seems to be formatting your message in a weird way.

  As the statement

  SELECT «...» "THE DOUBLE;

  without formatting, to show your entry and after the exact output desired friom as, with as little in shape as possible.  It might be useful if you use some character like ~ instead of spaces (just for viewing; we will find a solution that works for spaces).

  To remove the text which consists of spaces and nothing else between the tags, you can say

  REGEXP_REPLACE (str

  , '> +<>

  , '><>

  )

  How is this string generated?  Maybe there is an easier and more effective way to keep the bad wrtings sub off the chain in the first place.

• Impossible to extract the data of an additional column in the table advance

  Hello

  We have an obligation to add an extra column to the table of advanced search. In addition, we need sort the table using this additional column.

  Now, we have achieved the following:

  1. the required VO was already extended previously and the additional column (LAST_UPDATE_DATE) is already present in the definition of the EO. So, we just added the tag for LAST_UPDATE_DATE in YOUR XML in the form:

  < ViewAttribute

  Name = "LAST_UPDATE_DATE".

  IsPersistent = "false".

  Type = "Oracle.jbo.domain.date"

  ColumnType = "DATE".

  AliasName = 'LAST_UPDATE_DATE. '

  Expression = "LAST_UPDATE_DATE."

  SQLType = 'DATE' >

  < / ViewAttribute >

  2 added a new MessageStyledText column, and updated the following property:

  Prompt = LastUpdateDate. Discover the Instance = TaskPerzSumVO. Display attribute = LAST_UPDATE_DATE. Sort Allowed = true

  The field is now visible in table advance and whenever we seek, attaches the value as ' 1901-01-01'. While I checked manually in the respective table, we have the appropriate data. But in the front end we do not get the data in our additional column of table in advance. In addition, if we try to sort the table by clicking the column LAST_UPDATE_DATE, we get the NPE error. Spec of NullPointerException is as follows:

  # # 0 in detail

  1. java.lang.NullPointerException

  at sun.misc.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:989)

  Kindly help us to obtain the appropriate data in the additional column. Thank you!

  Kind regards

  Zahid

  Hi Zahid,

  This is the error:

  29000: unexpected exception caught: oracle.jbo.NoObjException, msg = Houston-25003: TaskEO.LAST_UPDATE_DATE object of type entity activity not found

  Tag entity by its use should have only name of EO and not the name of the attribute.

  Use instead under the tag:

  EntityUsage = "TaskEO".

  Also, I mentioned that rather tags manually, add it please try Wizard VO to add this attribute in EO attributes available list.
