Variable-length string

• Stuck on query Substr() for variable length strings

  I have these sample data:
  

  GET sampledata
  WITH sampledata AS
       (SELECT '/customizations/ams/apps/oracle' v1 FROM DUAL
        UNION ALL
        SELECT '/customizations/webui/main/repository/developer/cz/apps/oracle' FROM DUAL
        UNION ALL
        SELECT '/customizations/webui/audit/oie/ap/apps/oracle' FROM DUAL)
  SELECT sampledata.v1 aa
    FROM sampledata;
    
  AA
  ------------------------------------------
  /customizations/ams/apps/oracle
  /customizations/webui/main/repository/developer/cz/apps/oracle
  /customizations/webui/audit/oie/ap/apps/oracle

  What I would really like to do is to extract the value between the slashes appearing before "/ apps/oracle /.
  
  If in the examples above, I want to extract:
  

  ams
  cz
  ap

  The problem is that the position of this element varies. In the sample data "AMS" appears after the 2nd slash, 'cz' after the 6th and "ap" after the 5th.
  
  I can get the value by one simple example:
  

  GET sampledata
  WITH sampledata AS
       (SELECT '/customizations/ams/apps/oracle' v1
          FROM DUAL)
  SELECT sampledata.v1 aa
       , substr(sampledata.v1,17, instr(substr(sampledata.v1,17),'/')-1) aj
  from sampledata;  
  
  AA                              AJ
  ------------------------        ---------------------
  /customizations/ams/apps/oracle ams

  But of course, it is useless, that the segment I want to put the hand isn't always in the same place.
  
  Any advice much appreciated!
  
  Thank you

  Hello

  If you're on g 10 (or higher), try regular expressions:

  SELECT sampledata.v1 aa,
         regexp_replace(v1, '^.*/([^/]+)/apps/oracle.*$', '\1') aj
  FROM sampledata;
  

• Format analysis of the measurement data of variable length for Newport THP/N

  I try to analyse the response of a sensor of zED-THP/N of Newport. The answer is back with ID SEQ TYPE TEMP C HUMD %.

  ID = 1, SEQ is constantly changing, TYPE = 15, temperature = nnn.n

  I am trying to capture the Temp, and this presented a challenge. (The humidity is easy, I'm reading after the C - 5 has 'C')

  The SEQ number starts as n and evolves to nnnn... so using 7x4a does not work due to the changing length of the SS.

  When I use '15' 4, because the Type is still 15, and SEQ contains a 15 in the number, which also becomes a problem.

  Everything that I have which is constant is that there are spaces between each value and the value of temperature I'm looking begins after the 3rd space.

  Any help would be great

  Great... progress is good.

  If you use the single command, tol ERDG00A return all my sensors in a given request:

  The request channel data that must be completed is channel 0. All other channels should be empty. Not \r, just empty. I should have mentioned that in the original post. Then configure the channels as before, ensure that each channel of moisture is a\r\n. The next channel group must be a\x20.

  To explain, just one tells DASYLab to find the number of variable length, and he still needs a delimiter to put end. many devices use a comma, but they use a space. The hexadecimal ASCII for space is 20, so say us DASYLab to find numbers in a string of ASCII and stop when he finds a space, using the notation of DASYLab to hexagonal \x20.  notation for the carriage return character (\r isor hex 15), and \n is the notation for the line break ( or hex 12).

  15 84 0 18.5 C 64.5%
  1 50 15 C 18.4, 64.2%
  2 214 15 18.5 C 64.7%
  3 237 15 18.3 C 64.3%
  

  I like the idea of a single data request command for all four channels - less necessary communication protocol. In interpreting the device number, you will be able to ensure that the analysis works correctly.

  CH 0: a\x20

  CH 1: a\x20

  CH 2: a\x20

  CH 3: a\x20

  CH 4: a\r\n

  CH 5: a\x20

  CH 6: a\x20

  CH 7: a\x20

  CH 8: a\x20

  CH 9: a\r\n

• Record and play variable a string will not copy

  I have a variable of string - serialization of an xml variable result - in a process.

  It has a length of 'unlimited '.

  When I opened the recording and playback, there is text indicating the beginning of sequenced xml:

  < node_x

  That's all that I can see.

  Unfortunately, the option 'copy value' in the menu contextual is dimmed, just at the moment where I most need!

  This is normal behavior for a scenario like this?

  Is there anyway that I can get to copy...

  Thanks in advance!

  At least try to open and close the variable perspective.

• Get the bind variables name string SQL or the cursor

  Hello
  
  Is there way to get of the bind variables name string SQL or the cursor?
  
  Example of

  DECLARE
    l_sql VARCHAR2(2000);
    desctab DBMS_SQL.DESC_TAB;
    curid   PLS_INTEGER;
  BEGIN
  
    l_sql := 'SELECT * FROM emp WHERE mgr = :X and deptno = :Y';
  
    curid := dbms_sql.open_cursor;
    dbms_sql.parse(curid, l_sql, dbms_sql.NATIVE);
    ....
  END;

  What I mean with the SQL string:
  I love to get using some functions from above code variable l_sql all the bind variable.
  In this case the function should return array where is for example: X and: Y
  
  Back to bind the cursor variable names, I mean same but rather string I pass number of cursor.
  
  Y at - it sucks ready function or some may share a code customized for this purpose?
  
  Thanks
  
  Kind regards

  I found there are wwv_flow_utilities.get_binds of the function not documented in APEX packages that do what I want.
  Usage example

  set serveroutput on
  DECLARE
    binds DBMS_SQL.varchar2_table;
  BEGIN
    binds := wwv_flow_utilities.get_binds('select :P1_TEST from dual');
    FOR i IN 1 .. binds.count
    LOOP
      dbms_output.put_line(binds(i));
    END LOOP;
  END;
  /
  
  anonymous block completed
  :P1_TEST

  But I would not use these functions without papers as those who can change or there is no future versions APEX.
  Is there a documented function or the custom function that do the same thing as wwv_flow_utilities.get_binds?

• Pass arguments of variable length to an another variable length arguments

  Do not pass an argument of variable length to another argument of variable length

  For example

  public void call(name:String,..._params):Object

  {

  ExternalInterface.call("saveglobalscore",score) (name, params);
  }

  call ("test", "param1");

  "param1" is considered to be an argument with the type of array in the second function of «call», but is what I want to treat it as an argument as a string.

  The result is:

  < call name = 'test' returntype = "xml" > < arguments > <table > <property id = '0' > < name String > < / string > < / property > </ array > </ arguments > < / call >

  But what I want is

  < call name = 'test' returntype = "xml" > < arguments > < String > name < / String > < / arguments > < / call >

  I have to do is:

  public void call(name:String,..._params):Object

  {

  If (params.length == 1)

  {

  ExternalInterface.call("saveglobalscore",score) (name, params [0]);

  } Else if (params.length == 2)

  {

  ExternalInterface.call("saveglobalscore",score) (name, params [0], params [1]);

  } Else if (params.length == 3)

  {

  ExternalInterface.call("saveglobalscore",score) (name, params [0], params [1], [2] params);

  } else

  throw new Error ("I'm crazy");

  }

  This is a terrible solution, if it no work around?

  The compiler must can handle this situation.

  Try:

  public void call(name:String,..._params):Object

  {

  params.unshift (Name);

  ExternalInterface.call.apply (ExternalInterface, params);

  }

• Analysis of the variable format string

  Question, I have a string I need to analyze in separate string variables. Analysis errors out string if the string is parsed cannot fill every type defined in the string format. The problem I have is that the string length varies depending on multiple strings separated by spaces up to 13 different string types sometimes and sometimes only 6. Is there another way to scan the string in different channels with the command of token or something and not use this as the format varies?

  I've attached an example of what I'm trying to do.

• Global Variable length problem

  Hi all
  
  I'm moving a group of a pll key values.
  I'm holding all the key values in a text field that can contain up to 10000 bytes and I'm assigning the text field values to a global variable.
  This value of the global variable is read by pll and fetch the records using these key values.
  
  But I'm getting ORA-06502 error. This is a question about the length of the variable.
  Form builders help I got to know that this global variable can hold only up to 5000 bytes.
  
  Suppose that
  New_id is a text field that has more than 7000 bytes values separated by comma
  
  New_id is that a text field of type char length is 10000,
  
  +: global .new_cust_id: = Block.new_id +;
  
  On this line, I get ORA-06502 error, because this value is used by other packages.
  
  Can someone help how do I fix this
  
  Use forms [32 bit] Version 11.1.1.4.0 (Production) and Oracle database 11 g R2
  
  Thank you
  malandain

  Citing the Globals online documentation:

  A global variable is a variable of Oracle Forms whose value is available for the triggers and the subprogrammes in any module that is active in the current session. In previous versions of Oracle Forms, a global variable stores a string of length, for all uses up to 255 bytes. In Oracle 10g form, global variables are now limited to 4000 bytes when they are set or referenced using PL/SQL bind variable notation. for other uses, no limit is imposed.

  This means: If you access the global variable like this:

  :global.variable := value;
  

  You can store up to 4000 bytes in length. If you use the copy and name_in built ins you should be able to store up to 32767 bytes in a global variable.

• Can join us variable liquids with other variables or/strings of data in the declarations of liquids

  Can join us liquid variable with other channels for use in conditions or other liquid or variable methods?

  For an example simple Assembly variable/data with a string:

  {% assign newVar = globals.get.id + "#anchor" %}

  to get the result:

  newVar = / page-name #anchor

  or two variables in a conditional Assembly:

  {% assign var1 = "xy" %}

  {% assign var2 = 'z' %}

  {% If xyz is var1 + var2 %}     (but not + as in addition to math, actually join the 2 resulting from the chains of var1 and var2)

  so the if statement would be true.

  You don't need to capture Robert

  Adam,

  First is the sign + - in a liquid, it is 'more '.

  {{500 | more: 20}}

  And combine a string:

  {% assign var1 = "xy" %}

  {% assign var2 = 'z' %}

  {% assign combine = var2 | append: var1 %}}

  {{combine}}

  Capture is a double pass less effective.
