• "ORA - 01489:result of concatenation of string is too long" (the chain is small)

  Hello
  
  I am using the listagg as follows function but get ORA-01489: result of concatenating string is too long.
  
  SELECT LOCATIONID, LISTAGG (TO_CHAR (WHICH |)) ',' || (POSITIONY), ',') ADR WITHIN GROUP (ORDER BY SEQUENCENUMBER)
  OF POSITIONPOINTS
  GROUP BY LOCATIONID
  AFTER HAVING COUNT (SEQUENCENUMBER) = 20;
  
  When I try to run this in Oracle Sql Developer, he shows the lines first in 1550, then reports the error ORA-01489. In total 2612 lines must be returned, all values in ADR having a length of approximately 440 characters. An example of one of the lines that developer Sql is back is:
  
  22372682 410434.801,551142.885,410434.784,551142.875,410439.801,551141.922,410439.991,551141.795,410439.293,551138.303,410438.531,551137.668,410429.768,551134.302,410427.228,551133.159,410426.212,551132.143,410425.196,551129.667,410421.957,551114.3,410414.972,551081.28,410413.639,551076.136,410412.94,551073.66,410412.94,551072.326,410413.639,551071.628,410415.798,551070.612,410416.369,551069.469,410416.877,551068.834,410433.23,551061.795
  
  There are a few LocationIDs in table PositionPoints that have more than 20 entries (max is 254), and for these lines, I want the concatenated string more than the maximum of 4000 characters. However, where count (sequencenumber) = 20, the length of the concatenated string would be less than 500. Oracle running concatenations even for places that I've excluded with my HAVING clause and an error on these?
  
  I tried to run the query at the time Oracle Sql Developer and SQL Plus.
  
  Would be grateful if someone could shed some light on this issue.
  
  Thank you

  Yes, that's the explanation.
  HAVING is not WHERE it is applied after the grouping is performed.

• Unexpected error "the result of the concatenation of string is too long."

  Hello
  
  I use the Oracle 11.2.0 database.
  
  When querying my database with a common table expression that concatenates strings VARCHAR2, I get an error ORA-01489 even if I suspect that I am concatenating more 4000 characters.
  
  To be more precise, I have a table entity which basically stores the XML elements, including their parent element and their position of brother among his brothers and sisters. The CREATE statement for this table is listed below.
  
  CREATE TABLE (entity
  ID NUMBER (10,0) NOT NULL PRIMARY KEY,
  Name VARCHAR2 (100) NOT NULL,
  Parent NUMBER (10,0) REFERENCES Entity (ID),
  Sibling_Pos NUMBER (2.0) DEFAULT 0
  )
  ;
  
  Now, I would like for all items to be concatenated with their ancestors elements to a structure as follows:
  
  "(/ root_element(sibling_pos)/.../ancestor_element(sibling_pos)/parent_element(sibling_pos)/current_element(sibling_pos).
  (where root_element, ancestor_element, parent_element and current_element are fair values in the name column of the table of the entity)
  
  To do this, I use a common table expression that concatenates the values of name and sibling_pos as shown below:
  
  WITH entity_cte (lvl, id, path) as)
  SELECT 1 AS lvl, id, ' / '. name | ' (0' | sibling_pos |) ')' IN the path
  OF the entity
  WHERE parent IS NULL
  UNION () ALL THE
  SELECT lvl + 1 lvl, e.id, entity_cte.path | '/' || e.Name | ' (': cast (e.sibling_pos AS VARCHAR2 (2)) |) ')' IN the path
  Of entity_cte, e entity
  WHERE entity_cte.id = e.parent
  )
  )
  SELECT lvl, id, path
  Of e entity_cte
  ;
  
  After the insertion of certain values, I get the error ORA-01489, the result of concatenating string is too long. The maximum is called as 4,000 characters for VARCHAR2 in the oracle documentation and various Web sites. Of course, it is clear to me just by using the common table like that expression, I could run in such an error. However, because of the structure of XML documents, I doubted that channels resulting would be since a long time more than 4000 characters.
  
  So I reorganized my query to count the characters to concatenate instead of actually concatenate. The query is listed below, that the changes are marked in "BOLD":
  
  WITH entity_cte (lvl, id, path) as)
  SELECT 1 lvl, id, length ('/ ' | name |)  ' (0' | sibling_pos |) ') IN the path
  OF the entity
  WHERE parent IS NULL
  UNION () ALL THE
  SELECT lvl 1 lvl, e.id, AS entity_cte.path + length ('/ ' | e.name |) ' (': cast (e.sibling_pos AS VARCHAR2 (2)) |) ') IN the path
  Of entity_cte, e entity
  WHERE entity_cte.id = e.parent
  )
  )
  SELECT lvl, id, path
  Of e entity_cte
  Way to ORDER BY DESC
  ;
  
  The result of the query gives me a maximum length of 319 characters.
  
  To be sure, I also checked the maximum level (indicated by the column named lvl in the common table expression), which means that the maximum number of items in my way (the concatenated string). The result is 18. As I use VARCHAR2 (100) for the name column and add 5 charcaters in each level, the maximum number of characters expected to 18 levels would be 1890.
  
  So, now I wonder is the ORA-01489 may have triggered another reason? Or is there something else I'm missing?
  Any help would be appreciated. Other suggestions to track down the error are more than welcome. Thanks in advance.

  I found by trial and error that launch the query anchor seems to work, but I don't know why, then you can try this.

  with entity_cte (lvl, id, path)
  as
      (
      select
          1 lvl,
          id,
          cast('/' || name || '(0' || sibling_pos || ')' as varchar2(4000))  path
      from
          entity
      where
          parent is null
      union all
      select
          lvl + 1 lvl,
          e.id,
          entity_cte.path || '/' || e.name || '(' || cast(e.sibling_pos as varchar2(2)) || ')' path
      from
          entity_cte,
          entity e
      where
          entity_cte.id = e.parent
      )
  select lvl, id, path
  from entity_cte e
  ;

• Concatenation of strings to form an INSERT INTO statement

  I am trying to build an insert statement by concatenating strings. Basically, that's what I do:
  < cfset string1 = "INSERT INTO #tablename # (" > ").
  < cfset string1 = string1 & #colname # >
  < cfset string1 = string1 & ")" > "
  < cfset string2 = "VALUES ('" > ").
  < cfset string2 = string1 & #coldata # >
  < cfset string2 = string1 & "')" > "
  
  < cfquery = "insert" datasource name = "db" >
  # String1 string2 # #.
  < / cfquery >
  
  
  -----------------------------------------
  Also, if I change the < cfquery > tags to < cfoutput > I get a valid INSERT statement:
  INSERT INTO Habitat (AREA, ARTID, BIOTOP) VALUES (43, 37, ' text')
  
  But when I have the tag < cfquery > I get this error:
  Syntax error (missing operator) in query expression "' text"'.
  
  I tried to change the (' #coldata # ') to ("#coldata") and also tried ("#coldata #") and ("' #coldata # '"), but I get errors all the time...
  
  So. How can I do this?
  
  

  I'm not asking why you do this :)

  but you will need to use preserveSingleQuotes(). probably right around string2, but may not be wrong to just wrap the whole.

  
  #preserveSingleQuotes (string1 & string2) #.

I concatenated two strings and then participating in a housing structure. Nothing graphic when have two concatenated options, but it does not work when it's just the different types of wave are chosen.

  Hello

  ORA-01489 is one of these error messages that really means what he says. The error message you posted pretty much sums up the situation.

  What version of Oracle are you using?  (You must still include this whenever you have a question.  See the FAQ forum: Re: 2. How can I ask a question on the forums? )

  From 12.1 of the Oracle, there is an option to allow VARCHAR2s in SQL to be as big as 32767octets.  (The default is 4000).

  Otherwise, if you can't change the code, either do not run. or ensure that the concerned channels are quite short so the error does not occur.

  That the script is that it will update the 'FIELD_XML' (CLOB) field in the table "material". I know that it exceeds the maximum size. Is there another way to do this?

  You can try with CLOB variable declaration and concatenate the value you want in it.

  For example:

             tt.column5,
             tt.column6,
             tt.column7,
             tt.column8
      FROM material m, tmp_text tt
      WHERE m.NAME like tt.column2 || '%'
      AND tt.column9 = 'SI';
  
      v_clob CLOB;  
  
              begin  
  
    for u in material loop
      v_clob := '
                          
                            
                           
                           
                           
                           ';

• Select string?

  I have the string as # 456 123 and select (4) [as the second figure either] to add with others not.
  What should I do?

  What to do? What do you mean by "add with the other not? You mean you want to add mathematically the 4 and the 5 to get 9 or perform the concatenation of strings to get '45'? You want to add the 4 and the 56 123?

  To select a subset of a string, you can use the function of the subset of the string. There is a zero based index entry and one length. Index 0 is the # 1 index is 4. There is also a default length for entry, the rest of the chain. Wire 1 to that.

• Insertion of several strings in a 1 d array

  Hi all

  I am a beginner new to LabVIEW, so go easy on me. I tried to do for far too long and I thought I'd give forums a shot. I'm taking a picture 2D channels and their entry in a 1 d table. Sounds pretty simple, but for some reason, I just can't get it. The table then feeds into a ring of text. Thus, for example, say I have a table of dimensions 4 x 2 [a b c d e f g h], the output I want is a 1 x 2 [abcd, efgh] matrix. However the table could be 4 x 4 or 4 x 6, so this is not fixed. The ring of the text allows the user select among the options (2 in this case).

  I hope that I have described my problem clear enough for people. Taking the strings in the 2D array and put them in a chain are as close as I got what I want. I also tried the table to a spreadsheet string, but he gave me a long string. Unless there is something blatantly obvious that I'm missing, could someone give me some advice? Also, I would just add that everyone telling me to go read the tutorials, etc. of source material. Believe me, I have. Carefully.

  I have included a picture of the section of code that I'm trying to make it work. And Yes, I realize that it will not be anything to the ring of text entry right now, which is currently just how I saved it.

  Replace the while loop with a loop For.

  Do not use the subset of the array, simply use the tunnels of automatic indexation.

  Use the concatenation of strings on your table 1 d and you will have a single string.

  Use the automatic indexation on the exit tunnels and you will have a table 1 d of these channels.

  (You may need to convert the 2D table before feeding it into the loop For).

• Concatenate the strings from VISA

  Hello people,

  I'm still fairly new to LabView, please bear with me.

  I'm interested in doing a Subvi, which will receive bytes on a VISA from serial port and write each line to a greater (concatenated) string, so it can later be stored in a file. In simple terms, I want to save all the data on the serial port for 8 tests to be completed. There will be 6 cases of this in the parent VI, so he needs be modular.

  I expect a series of 8 channels of the source serial communication, each line begins with "Success" or "Failed" then the test. for example:

  Past test1

  Failure of test2

  Past of test3

  Past of test4

  .

  .

  .

  The current method I use must react when there are present bytes in the buffer in series, and then identify a match (currently it only identifies a match of 'Success').

  Is it possible to get a match for the substring to 'Success' OR 'failure '?

  How can I place all these strings on a chain? Concatenation of strings do not work because I'm having the same input string of the VI...

  Any help/input would be welcome, thank you.

  Here is a basic example of using to concatenate strings. Since it is always very difficult to know if you call your Subvi several times or if you call once and want to to read all the results I won't comment much more on it. This example would read all the results and the output format string you want to write to a file later or do whatever you want with it. The basic constructs of what you will need are illustrated here. How to encorporate in your application will be difficult to say without any code beyond the wick you have posted.

• String ActiveX Server property

  Hello world

  I am developing an application using LabWindows/CVI 8.1 on a machine WinXPSP3. To enable easy automation of functions in my application, I decided to add an ActiveX Server interface to my request and the first tests look very promising. However, after I introduced a property of type string to my ActiveX Server I get a strange error when the get method is called by the customer. The code generated automatically from the ActiveX server receives the application string and converts it to a BSTR that is returned to the client. The string pointer returned by the demand function is converted to this type BSTR and later in auto genereated the string pointer is freed with a call to CA_FreeMemory (). Generally that it works fine but when I run my application in mode Debug execution is interrupted at this point (even when there is no breakpoint) and the debug window displays the following message:

  Heap [application_debug.exe]: invalid address specified to RtlFreeHeap (00140000, 027995E0)

  In fact, the allocated memory is not released.

  I have generated a small sample project that reproduces the issue. The error occurs in autotest_axs.c on line 71, a breakpoint is set for convenience. The attached VI LabVIEW is used to serve the client ActiveX and makes the necessary calls to reproduce the effect. Simply build the CVI project in debug mode and start the VI during execution of the implementation of the CVI.

  At the moment I don't think I'm doing something wrong, maybe everyone at OR has an idea.

  Thanks in advance!

  In the AutotestApplicationget_String function in the autotest.c file, you should use the function library ActiveX CVI CA_AllocateMemory to allocate memory for the string. Instead, you use the ANSI C malloc function. This affected memory is released later by calling CA_FreeMemory call to the CaSrvrAutotestApplicationget_String function in the autotest_axs.c file. It is allocated in the memory manager and deallocated in another.
