  Hello
  
  I want to extract the second sysdate value using the EXTRACT function.
  When I run the following query I get an error;
  
  SELECT extract (second OF SYSDATE) FROM dual;
  
  ORA-30076: field of invalid extract for the source of the extract.
  
  When I do to extract the month I get the correct result.
  
  Is there some necessary formatting by specifying the sysdate (or any other date value) in the query. ?

• How to extract the string values

  Hello

  }

  ]

  }

  ]

  }

  Hello

  Too bad, that you do not have version 12. Then, you can use the function JSON_VALUE mentioned previously.

  Here's something you can do in your version:

  SELECT LEVEL AS n

  , REGEXP_SUBSTR (: str)

  , ' "propertyvalue": "([^"]*) "

  1

  LEVEL

  NULL

  1

  ) AS propertyvalue

  OF the double

  CONNECT BY LEVEL<= regexp_count="" (:str,="">

  ;

  If you want to know that adapts to your specific problem, post CREATE TABLE and INSERT statements for some sample data and the exact results you want from these sample data.

• How to extract a string from a varchar column value

  Hello
  I have a varchar2 column that got the xml data. I want to extract the value of a tag < test > < / test >
  
  I can't use EXTRACT because the column is not XMLTYPE.
  
  Please suggest.

  Insert first only the first two columns:

  INSERT INTO TESTXML (id,name) VALUES(1, 'ABCDEFTEST');
  INSERT INTO TESTXML (id,name) VALUES(2, 'XYZUVWTEST');
  INSERT INTO TESTXML (id,name) VALUES(2, 'XYZUVWTES');

• How to extract a string from a TextRange

  Dear Experts,

  How can I retrieve the string "=? UTF - 8? B? LDvGhsLCBGcmybYk? ="between the markers of coding?

  Currently, I am able with the help of code as

  \starttext = activeDoc.Find (startText.beg, findParams);

  to find the exact begins and demand an end to the chain and I created the Base64TextTextRange.

  With the statement activeDoc.TextSelection = Base64Text; I can highlight the text in my document.

  I tried further with

  Base64Item = activeDoc.GetTextForRange(Base64Text,Constants.FTI_String);

  Base64String = Base64Item.toString ();

  But still, I am not able to see the string in the object of the Toolbox browser.

  Note that I do not use the GetText method because the string is only part of the paragraph.

  Thanks for the tips.

  The GetText method, you get an array of text elements. You need to assemble the parts of the string of the text element of individual objects in a single string, then fing encoding markers. Assuming that your Base64Text is a range of valid text, your code should look like this:

  var saTextItems = activeDoc.GetTextForRange (Base64Text, Constants.FTI_String);

  var i;

  var sFullText = ";

  for (i = 0; i< satextitems.length;="" i++="">

  sFullText += saTextItems [i] .sdata;

  var iPos1 = sFullText.indexOf ("=?") + 2 ;    / * assuming =? is the beginning marker and adding 2 to point to the first position behind it * /.

  var iPos2 = sFullText.indexOf ('? ') =", iPos1);   / * Add the start shifted for good measure, but that may not be required here * /.

  var sBase64String = sFullText.substring (iPos1, iPos2);

  Alert (sBase64String);

  I would like to know if it works for you. And mark the answer as correct if it does.

• How to extract the string

  I know that I did it in before CVI...

  Only, I don't remember how I did it...

  (braindead today?!?)

  Here goes:

  FindPattern "little."

  resulting string: "" Mary had a lamb.

  What I have works to find the model and it is place.

• How to extract string in JSON data where the value in a table

  Hello

  Structure of JSON string

  {'name': 'John', 'name': 'kumar', 'address': [{'Address1': 'value', 'place': 'value'}, {'address2': 'value', 'place': 'value'}]}

   

  
  How to extract the value of the address of the list.

  If you have control over the format of data, it is best to rename address1 and address2 to have the same name, for example "address". Then, it can be analyzed that way (I've also simplified other code a bit):

  JsonDataAccess jda;
  QVariant v = jda.loadFromBuffer(jsonString);
  QVariantMap m = v.toMap();
  QString name = m["name"].toString();
  QString surname = m["surname"].toString();
  QVariantList addresses = m["address"].toList();
  foreach (QVariant addr, addresses)
  {  QVariantMap addrMap = addr.toMap();
    QString addressValue = addrMap["address"].toString();
    QString place = addrMap["place"].toString();
  }

• How can I get the text value of an element XML in MXML?

  Hello

  
  

  I have the following XML loaded into a variable of XML type:

  Properties of <>
  the RIMpro data collector Configuration < comment > < / comment >
  < key="server.pear.username"/ entry >
  < key = "enter server.apple.retry.times" > 5 < / entry >
  < Enter key = "rdc.proxy.host" > http://192.168.1.2:8080 < / Entry >

  /Properties >

  I can easily get the key attribute displayed in a DataGridColumn by setting the dataProvider my variable and the data in "@key" area  But I don't know how to get the text value in a second column...  Is it possible or do I have to change my XML to something like this:

  Properties of <>
  the RIMpro data collector Configuration < comment > < / comment >
  < key="server.pear.username"/ entry >
  < key = "enter server.apple.retry.times" value = "5" > < / entry > "

  /Properties >

  Thanks in advance.

  Yes, you'd better change your XML structure to fit the internal mechanisms of the DataGrid.

  As model dataField require each element of the grid line to have a named property to display, otherwise you will be forced to overcome this model to the custom help labelFunction for the particular column that will implement your custom actions on how to extract the appropriate data for this column of the grid line item. It will be much more complicated that just reorganize your xml structure.

• Need urgent help! In my Vision Application, how to extract the parameters of the geometric model specified curve was generated by the template editor OR?

  I have an application of machine vision, in which the geometric pattern match technique was used to find the target in the images of type variant.

  as we know, we do a geometric model by model OR editor in the editor we can adjust the parameters of the curve specified settings to get the desired curves and we derive the custom box to ignore during the match. then we save the use of the same model in our application of vision.

  Now my question is coming. When I program my request for the geometric game. I have specified the parameters of the curve for the entrance of the IMAQ Advanced Setup learn ringtone 2, of course, I have to adjust this identical to the model, but I don't know how we extract the geometric model. I tried all the methods, for example, I can read data custom, IMAQ get characteristics of the geometric model(it's just for the basic functionality? so is there even a VI based edge?), even at anasys PNG file formats! But I can't read the info of the geometric model by myself!

  It is also illogical to adjust the CURVE SETTINGS manually again for the " IMAQ Advanced Setup Learn Pattern 2" after that I already have in the template editor OR!

  Hello

  Why do you need to specify the curve settings once again, if you have already built a model using the template editor? You don't need to use "IMAQ Advanced Setup learn geometric model 2 VI" to find games (see the attached example).

  You can wire the 'curve settings' control to 'IMAQ configuration geometrical game model 2 VI', but the values are not used if wire you a Boolean true to the node "use learning curve settings" (it's like that by default). To prove it, I enclose a small program with pre-created model (using the template editor) for a geometrical alignment. The model and the test of three images are also included.

  Try changing the settings of the curve with the 'use know curve settings' enabled, and you will see the corresponding score remains the same. Disable the Boolean control, then try to change the curve settings.

  Also take a look at the detailed help for "IMAQ configuration geometrical game model 2 VI", specifically the "learning curve parameters of use."

  I hope this helps.

  Best regards
