• How to display the three months by guest

  Hello
  I have a requirement in the dashboard,
  
  There is a prompt of the month, if I select a month, it will show three months of data.
  
  example, if I select '201108', it appears 201107,201108,201109.
  
  If I use '+' or '-' in the calculation of the month, he has a problem, as in the whole of the year two, 201012,201101,201102.
  
  So, how can I achieve this requirement?
  
  Thank you!

  example, if I select '201108', it appears 201107,201108,201109.

  If I use '+' or '-' in the calculation of the month, he has a problem, as in the whole of the year two, 201012,201101,201102.

  I know that's not easy, but you have to think about it more logically. I know you got it to the point that you select month Jan or Dec as 201112 GOLD 201101.

  FOR EXAMPLE: SUPPOSE I CHOSE 201112
  Here you must create a report MID with 3 passes as CURR MTH, PRV MTH, NEXT MTH
  In the COMING MONTHS apply a logic, such as:
  -Convert "CURR MTH + 1' TANK '.
  -2 EXTRACT CHARACTERS RIGHT
  -EXTRACT IF = 13 THEN CONCAT (EXTRACT 4 TANKS LEFT - convert INT and add 1.) This will give you 2012 and concat with 01). New change to INT
  Report: 201112, 201201, 201111

  FOR EXAMPLE: SUPPOSE I CHOSE 201101
  PRV MTH apply logic as:
  -Convert CHAR 'CURR MTH - 1'.
  -2 EXTRACT CHARACTERS RIGHT
  -EXTRACT IF = 00 THEN CONCAT (EXTRACT 4 TANKS LEFT - converted to INT and minus 1. This will give you 2010 and concat with 12). New change to INT
  Report: 201101, 201102, 201012

  Thank you

  Ok. Wasn't sure. Thank you for that clarification.

  .. .but please make an attempt with XMLTABLE XMLQUERY, XMLCAST (or CAST) and other XML functions that support XQuery and not to use the engine of 'old '... I hope that these features will keep things as it should...

  .. .If not... create an SR with support of Oracle on this issue. Changes, if you base your SR on these 'old' operators XML/SQL and functions that are her will not be able to help, mainly due to the fact that your last version and stuff like EXTRACT / getStringVal() etc. are announced officially discouraged in this 11.2.0.2.0 version. As far as I know the t.xmldata.extract, the xml_type.extract and the other syntaxes, outlaw count of 10.1 (although I know, he appealed to java / OO people kind).

• Extracting columns with non-English characters?

  Hello
  
  I have a query using SQL Developer on a table that contains several names of companies from different countries, and is one of the controls I should do to ensure consistency of data to find all the rows that the company name contains special or non-English characters (such as c, a, as example).
  
  I don't know what can I use to do this. I tried to gather using NLS_SORT, but it did not work.
  
  Is there a way to select only the lines that contain these special characters or non-English, excluding the results the lines containing only English characters? Please have in mind that we have a lot of languages in this table.
  
  The area that I would like to make the conditions is VARCHAR2.
  
  Please let me know if there is any additional information I should give you so that you can help me.
  
  Thanks in advance for the help.
  
  Kind regards
  Luis

  Just list all characters that or not special for you, use something like

  with test as
  (
  select 'Behringer Harvard Eldridge Venture, LLC' txt from dual
  union select 'Behringer Harvard Redwood, LLC' from dual
  union select 'Behringer Harvard Lovers Lane Venture I, LLC' from dual
  union select 'Atlas Pipeline Mid-Continent KansOK, LLC' from dual

• How to: Extract the first three characters of a text field

  Greetings-
  
  What is the best method to extract the first three letters of a text field?
  
  I need to extract the first three letters of a text field (surname in this case),
  so I add other components to create an identification number for
  a person.
  
  This identification number which must be created consists of the
  date of the person by birth, last 4 digits of social security number and
  the first three letters of the person's first name.
  
  Example:
  == > Date of birth: 15/11/45
  == > Last 4 SSN: 6654
  == > Name: Smith
  
  Identification number would be:
  == > 1115456654SMI
  
  Leonard B
  
  
  

  That should do the trick:

  I put your values in the variable, simply replace the names, according to the needs
  
  
  

  This removes all the string of the / your birthday (if it's a string!) and puts it in the variable id:
  

  It takes the 4 last letters/digits of your social security number string and adds it to the id:
  

  It takes the first thre letters/numbers from your last name variable, capitalizes and adds to the identification string
  

  It will be useful.

  Unless the site you develop is for the Asian market, I don't know why you want to use that particular font. The Basic, standard and digital alphabet punctuation glyphs has sans serif, Roman characters, but the rest is thousands of Kanji characters. While you can use the font .ttf and .otf and web fonts, it would be very unusual to use one so great. Pages should load quickly and 78 MB, with a value of faces to download for those who have connections slow Internet is not fast.

  I would take a different font without serifs. There are literally thousands who look identical or virtually identical to Yuanti.

  131 free and high quality without font serif to choose here. I'm sure you can find a desired.

• Separation of the characters in a string

  I have a string in which all characters are separated by a space. I want to extract each of these characters to different substrings. Is there a way to do this?

  need =>

• Regular expression help please. (extraction of a subset of the string between two markers)

  I haven't used regular expressions before, and I can't find a regular expression to extract a subset of the string between two markers.

  The chain;

  Stuff of header I want
  Stuff of header I want
  Stuff of header I want

  Stuff of header I want
  Stuff of header I want
  Stuff of header I want

  6 ERRORS
                       
  Info I want to line 1
  Info I want line 2
  Info I want line 3
  Info I want to line 4
  Info I want to line 5
  Info I want line 6
  END_ERRORS

  From the string above (it is read from a text file), I try to extract the subset of string between ERRORS 6 and END_ERRORS. The number of errors (6 in this case) can be any number from 1 to 32, and the number of lines I want to extract will correspond with this number. I can provide this number of a caller VI if necessary.

  My current solution, which works, but is not very elegant;

  (1) using Match Regular Expression for the return of the string after you have synchronized the 6 ERRORS

  (2) uses the Regular Expression matches to return all characters before game END_ERRORS of the string returned by (1)

  Is there a way this can be accomplished using 1 Regular Expression Match? If so someone could suggest how, as well as an explanation of the work of the given regular expression.

  Thank you very much

  Alan
  

  

  I used a character class to catch any word or whitespace characters.  This put inside parentheses a substring matching the criteria that you can get by developing the node for regular expression matching.  The \d matches the numbers and the two * s repetition of the previous term.  So, \d* will find the '6', as well as "123456".

• Extract ODBC data Long field names

  I need to extract some data created by the 4 lookout data logging (files .thd).  Is it possible to do so. I use a PC that does not have installed belvedere, I only database files

  What I got so far is to export some fields whose names are less than 62 characters (using the program Logos 4.5 and driver ODBC database of 4 of Citadel by strict limitation of the field at 62 names). If I increase the limit to about 100 required to extract all the fields I can't export to Microsoft Query or any other software (which supports the import of ODBC database). I've tried several programs but usually they jump a message you can read that one point in time (or they do not see the fields or values at all)

  Please, can you tell me a way I can extract the data?

  The lifecycle of database is not applied in an aggressive manner. The database do not try and remove data simply because life has expired. On the contrary, the life expectancy is applied only when new data are currently recorded in the database and the log would need to increase the size of the database to store incoming data. The rate at which data are removed from the database may vary according to the rate at which new data are recorded in the database. If the frequency of recording is slow, it may take a long time for the data to be deleted.
