  Code required? This is NOT a coding service. This is a forum to help people with their questions on SQl, PL/SQL, or problems they have with the code THEY have written.

  See the doc of the PL/SQL language - he has examples of use of these three methods of parameter.

• Procedure with a variable number of columns

  Hi, I have a procedure that looks like this:
  
  PROCEDURE PROC (p_cursor sys_refcursor OUTPUT)
  
  In the procedure, I build query dynamically and the number of columns varies during execution.
  
  In the end I do
  
  OPEN for REQUEST P_cursor
  
  
  Then I do call it,.
  
  call PROC (?)
  
  My question is, how could I go on the running query of this procedure, and then adding lines or by modifying the existing results, then return the changed data?
  
  I want to do is add a new rank based on a condition, so I still need to return any number of columns, but I need to modify the results before I return them.
  
  Is it possible to do? I need to do some calculations on columns (variable columns), create a new line, insert in the result set and return this new set of results.

  A sys_refcursor is ideal to return to a front end gui such as .NET or Java, which can then use this cursor to retrieve data.

  In PL/SQL, there is no point in using a sys_refcursor unless you know, at the time of the design/build the columns returned are going to be.

  If the columns resulting are dynamic, so you have no choice but to use the package DBMS_SQL, where you can analyze and run any SQL statement you like and then use the package DBMS_SQL to describe what are the columns that result and how they are. From this, you can reference the columns by position, rather than by name.

  for example

  CREATE OR REPLACE PROCEDURE run_query(p_sql IN VARCHAR2) IS
    v_v_val     VARCHAR2(4000);
    v_n_val     NUMBER;
    v_d_val     DATE;

    c           NUMBER;

    d := DBMS_SQL.EXECUTE(c);
    --
    -- Describe the columns returned by the SQL statement
    DBMS_SQL.DESCRIBE_COLUMNS(c, col_cnt, rec_tab);

  11 g, you can create a sys_refcursor and the DBMS_SQL package then allows you to convert this refcursor in a DBMS_SQL cursor so that you can get the description of results and do the same thing. It is not available before 11 g well.

  However_ before any of this, you should really ask yourself if there is a real need to create queries dynamically. There is rarely a need to do and if you find that it is common in your application, then it is often a sign of poor design or bad defined the needs of the business (leaving the technical side to try to be 'flexible' and hence leading to unmaintainable code etc..).

• How to perform procedures with REF CURSOR & PLSQL settings table in SQL Dev?

  I have 3 SQL Developer. I create a procedure with a set of tables/PL/SQL as an input parameter and a SYS_REFCURSOR as output parameter.
  
  When I press the green arrow (Run button) block the dialog box run PL/SQL PL/SQL has no place at the PL/SQL table with records of entry and also to see the output of the SYS_REFCURSOR.
  
  I get the error ORA-06550 and many other errors when I run the present.
  
  How to do this please?

  In the debug code, lose the ABS. Prefix the SYS_REFCURSOR QC_SQL_DEVELOPER_TEST.
  Also, do not use same name of your settings on your bind variable (so e.g.: OUT_REF_CURSOR).
  REF CURSOR is supported output types, so you will get the output of their share in the output tab.
  However the output system does not recognize your own types as your PL/SQL table. You need to write an exit procedure yourself, indexing correctly, using the DBMS_OUTPUT.

  Have fun

• Call the PL/SQL procedure with different parameters?

  I use PL/SQL for web development. I have a page of PL/SQL which collects information and returns the user off site with one return url (another PL/SQL procedure).
  
  I have the return procedure with every documented return variable (default null) in order to always take the return. However, there are (reported... cannot reproduce because of the nature of the business) cases where a 404 error is returned because of the incompatibility of parameter.
  
  Is it possible to proceed regardless of the parameters? Someone at - it suggestions?
  
  Thank you!

  My problem is that they sometimes send back of settings that do not match what I expect.

  Use the interface "+ flexible +" mod_plsql - see the Oracle® HTTP Server mod_plsql user's Guide for the documented details.

  The signature of the procedure parameter is as follows (it is called by mod_plsql using tables of name value pairs):

  create or replace procedure Scott.MyWebProc( name_array owa.vc_arr, value_array owa.vc_arr) is
  ...
  

  In your code, you just browse the berries to get the name values passed query string. You can even filled an associative array in your code (a table indexed by string and no number, where the index string represents the name of param)-this approach can make it pretty easy for the code make reference to a parameter, with little effort on your part to provide an interface to query by name for code to get the value of a parameter name.

  To enable the flexible (aka parameter 2) call interface, precede the call to web with an exclamation character. For example

  http://my-webserbver.my-domain.com/pls/dad/!scott.mywebproc?name-1=val-1&name-2=val-2..,name-n=val=n
  

• How to call a stored procedure with a REF CURSOR output parameter

  I'm looking forward to example calling a function/stored procedure with a REF CURSOR output parameter and get the result.
  In other words, I have a stored function/procedure that runs a SELECT statement using the OCI library and then he could get the values of each row and each column.
  
  I put a code snippet, it have only the main thing to call a simple stored procedure and to print the name of each column of the cursor, but I couldn t to print out values in the table that calls the stored procedure.
  I understand that the next step is to call an OCIStmtFetch.
  How to associate the slider with the OCIStmtFetch?
  
  If you need more information, just tell me.
  
  I use ANSI C with HP - UX (HP - UX C) operating system and Oracle 10 g.
  
  
  Kind regards.

  Hi Antonio,.

  I see this:

  c_buf=(ub1 **)calloc(sizeof(ub1 *),3);
  
  ...
  
  rc=OCIDefineByPos(pOciStatCursor,&pdef,(OCIError *)pOciError,pos,c_buf[pos-1],size+1,(ub2)type,(dvoid *)c_indp[pos-1],(ub2 *)0,(ub2 *)0,OCI_DEFAULT);
  

  That I don't understand. You allocate space for 3 pointers ub1 but I don't see where these pointers are then initialized to point to where the data is to be stored.

  I do not read correctly?

  Sorry for posting code long, but here is an example of code that I have. It is much more 'code' for your code, but maybe that will be enough...

  NOTE: This is just the code example and not rigorous. For example, I don't check the memory, allocations etc in this code!

  Kind regards

• I have an infinite number of folders in the bookmarks bar

  In my favorite, I have an infinite number of files "bookmarks bar". Not only is this annoying, but I think it can be causing my browser not meet often enough. How can I solve this?

  COR - el said

  Have you run a check of places.sqlite as I posted above?

  Yes, I did. I unfortunately did not work. The only thing that works so far is disabling iCloud and Sync and manually delete the bookmarks. The problem is that if I turn on Sync, files return

  Change your password synchronization using a camera, which will wipe your data from the sync server and allow a fresh load data not corrupted since this device "cleaned." And run Places maintenance on each device before plugging it back in sync with the new password on each computer in your office / portable computer devices.

  Scroll down and look at the Version information.
  Version 1.4.14.1 - signed
  Published on October 27, 2014 654,5 kB
  Works with Firefox 22.0 and later versions

  I wonder if this extension is still compatible with current versions of Firefox?
  Just a hunch, but since Firefox for iOS beta was released last summer, "we" seem to have had a "slight increase" the number of threads similar to this one - support describing the proliferation of bookmarks files that are not part of Firefox for desktop / laptop, but rather added by a "3rd party" or a mobile device.
  I can't test it, as I don't have mobile device not (and if I did it would be Android or based filed). I get suspicious when an add-on that "mess" with a feature that is as sophisticated as the database of places and/or participates with Sync is that long without an update.

  And considering that Sync 1.5 was part of the 29 of Firefox, I wonder how compatible iCloud bookmarks always support Firefox to Firefox 22 is with Firefox now-a-days. A bit of incompatibility or the corruption of data multiplied by Firefox by contacting the synchronization server whenever Firefox is started is not very far-fetched. And then synchronize re - corrupt Firefox once Firefox connects to Sync... See where I'm going?

  Try going into settings > FaceTime and turn off FaceTime. Then go to Messages and turn off iMessage.

  Turn off your phone and then new.

  RETURN to FaceTime and turn it on again, even with iMessage. He has to try to reactivate and your new number should appear (you can see this more down in the addresses to send & receive). You may need to log into your Apple ID for this operation.

• Electric trigger DAMA IQ &amp; check for new records to collect an infinite number of records

  Hi all

  I have some difficulties with the help of the trigger edge power IQ & questioning the DAMA if it has samples/records ready for pick up.  I have reviewed the documentation on the support to the screw and the examples provided with the driver of the ACCA and have not been able to solve my problem on my own.    What I'm trying to do, is to have this VI capture periodic RF bursts that are larger than a specified threshold.

  I go to this topic in the following way:

  I put the number of samples I captured (finished) for each burst which crosses the threshold
  I put the number of records to capture to be infinite
  I said that the rising slope and the appropriate threshold
  I have then to validate the configuration of the ACCA and start acquiring
  I have then go into a loop and check the backlog of samples as well as the acquisition is
  If either of the above is true then I get the samples with the IQ extract complex WDT vi
  I continue looping until the user stops the vi with a button on the front panel
  I went on this path that I didn't block indefinitely or for long periods of time

  What I see is:

  I'll take one shot and then nothing else
  what the samples never back above zero
  that acquisition is ever complete
  If I switch out the IQ extraction with equivalent IQ reading and ignore the completion back & I get documents like I expect

  My understanding is as follows:

  Electric trigger IQ does not have to be re-armed in VI
  that each trigger to fire IQ Power will create a new record containing the number of samples that I asked

  My questions:

  It seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?
  I receive multiple records pending upward on the ASB using this configuration?
  Why a record number is provided with the back of fetch get VI?
  Why would I pick any folder, but the record of zero?
  I'm doing something wrong here?
  Is there a better way to do this?
      
  Thank you
  Russell

  Hi Russell,

  You are on the right track to get your application do what you want. Instead of check to fetch back, I suggest that lets you read the property node DAMA the "' Acquisition > Fetch > Records made" property to know when a new record was acquired. "

  > it seems that when the number of records is infinite that the acquisition is never considered as carried out when the State of the acquisition is verified, is that correct?

  That is right.

  > I get multiple records pending upward on the ASB using this configuration?

  Yes

  > Why a record number is equipped with the rear of fetch get VI?
  > Why would I pick any folder, but the record of zero?

  You ask DAA for an infinite number of records. File 0 started the first trigger seen. Record 1 to the second outbreak (end of disk 0) and so on.

• Call Oracle procedure with variable

  Experts,

  I pass arguments through script to Oracle procedure, use the input value and pass to the procedure.

  Oracle procedure Gets the input value, run the query, and all connect to the log file.

  I am facing a few challenges, seems to be the error of syntax or data type

  1. even if I pass all the script parameter still run complains of wrong number or type of arguments.

  There are three numbers followed by a date variable

  2. how to pass a variable value with the INTERVAL function, it should take the value of the variable lThird for example "" AND date > = date + INTERVAL '30' MINUTE; "but somehow, after trying different variants still get error like interavl not valid."

  Error:

  PLS-306: wrong number or types of argument in the call to proc

  Hello

  With regard to your needs:

  My current problem is

  1. how to store the SELECT results in the log file, ask has several columns with multiple lines

  2. what happens when SELECT brings out no line?

  I have re-used, corrected and adapted to your procedure:

  Package:

  CREATE or REPLACE PACKAGE pkg

  AS

  PROCEDURE proc (lFirst in number,

  lSecond in numbers

  lThird IN varchar2,

  curReturn to sys_refcursor);

  Pkg of END;

  /

  CREATE or REPLACE PACKAGE pkg BODY

  AS

  PROCEDURE proc (lFirst in number,

  lSecond in numbers

  lThird IN varchar2,

  curReturn ON sys_refcursor)

  IS

  BEGIN

  OPEN FOR CurReturn

  SELECT *.

  WCP

  WHERE empno in (lFirst, lSecond)

  AND hiredate > = TO_DATE (lThird, 'YYYYMMDD');

  END proc;

  Pkg of END;

  /

  Shell script: test_sql.sh

  #! / bin/ksh

  V_user = scott

  V_pass = Tiger

  echo "Oracle procedure in progress"

  Req ='sqlplus-s $V_user / $V_pass<>

  var refcursor rc

  exec pkg.proc ($1, $2, $3,: rc)

  print the rc

  output

  EXPRESSIONS OF FOLKLORE"

  echo "$req" > logfile$ $

  PS:

  (1) you must put the name of your user/passwd name and table (I used the scott/tiger schema by default with emp table). This is just to show how to retrieve a refcursor output in a script.

  (2) I used logfile$ $ as output file; You can use any other file or method name to redirect the output to a file

  Call us at:

  19000101 7934 7900 test_sql.sh

  PS: As noted in the previous posts, you cannot define a VARIABLE of type DATE in sqlplus (or a Unix script); You can send a string and perform the conversion in the SQL section.

  If no line is not recovered, you get the following in the log file:

  PL/SQL procedure successfully completed.
  
  no rows selected

• CC of Dreamweaver on iMac very slow to open sites with a large number of files

  In recent weeks, a site I've worked regularly for several years began to take 10-15 minutes to open. A pop up says it checks the files, but the button that should allow you to escape this process does not work. The site has about 120 000 files located in different folders, and this was never a problem in the past. To access the site, the only way is to wait until the course ends and the spinning ball to go. I read the thread on the port of Skype settings, but I think that this may be a different problem because even though I have installed Skype I rarely running and only one of my sites is affected.

  Any ideas?

  With a large number of files, it would be a good idea to disable the cache of Dreamweaver for this site.

  1. Site > Manage Sites.
  2. Select the site, then click on the pencil icon to change site settings.
  3. Select Advanced settings > local news in the list on the left of the Site Setup dialog box.
  4. Uncheck the Enable Cache.
  5. Save > fact.

  Another possibility is that your Dreamweaver cache is corrupted (probably with as many files). See remove a corrupt cache file.

• How to get 2 out of procedure with sql dynamic param?

  Hello

  following my other question on the treatment in the ranks, so that I did a procedure defined ranges for the table I want to deal with;

  I did another procedure to obtain a particular range for treatment and that's where I have a problem;

  My data are:

  {

  CREATE THE TABLE PRECUBE. TEST_STG_TMO_RANGES

  (

  NUMBER OF GLASS FIBER,

  MIN_RID VARCHAR2 (18 BYTE),

  MAX_RID VARCHAR2 (18 BYTE)

  )

  tablespace UTI_DAT;

  Insert into TEST_STG_TMO_RANGES (GRP, MIN_RID, MAX_RID) values (0, 'AABKSxAAEAACW3pAAA', 'AABKSxAAEAADqCICcQ');

  Insert into TEST_STG_TMO_RANGES (GRP, MIN_RID, MAX_RID) values (1, "AABKSxAAEAADqCJAAA", "AABKSxAAEAAD + wICcQ");

  Insert into TEST_STG_TMO_RANGES (GRP, MIN_RID, MAX_RID) values (2, ' AABKSxAAEAAD/QJAAA', 'AABKSxAAEAAECyICcQ');

  Insert into TEST_STG_TMO_RANGES (GRP, MIN_RID, MAX_RID) values (3, 'AABKSxAAEAAEFQJAAA', 'AABKSxAAEAAEL8ICcQ');

  Insert into TEST_STG_TMO_RANGES (GRP, MIN_RID, MAX_RID) values (4, 'AABKSxAAEAAEMSJAAA', 'AABKSxAAEAAEPwICcQ');

  }

  my package:

  {

  create or replace
  PACKAGE C_UTI_BASIC AS
  procedure P_GET_RANGE (table_owner_in in varchar2
  TABLE_NAME_IN in varchar2
  range_no number
  Min_RANGE_OUT OUT varchar2
  max_range_OUT OUT varchar2
  );

  END C_UTI_BASIC;

  }

  My procedure:

  {

  procedure P_GET_RANGE (TABLE_OWNER_IN in varchar2
  TABLE_NAME_IN in varchar2
  RANGE_NO number
  MIN_RANGE_OUT OUT varchar2
  MAX_RANGE_OUT OUT varchar2
  )
  is

  DDL_STATEMENT varchar2 (4000);

  Start
  
  DDL_STATEMENT: ='select MIN_RID, MAX_RID in MIN_RANGE_OUT, MAX_RANGE_OUT in '. TABLE_OWNER_IN |'. ' || TABLE_NAME_IN | "_RANGES where PRV =' | RANGE_NO;

  immediately run DDL_STATEMENT;
  DBMS_OUTPUT. PUT_LINE (DDL_STATEMENT);
  DBMS_OUTPUT. Put_line ('Min_RANGE_OUT :'||) Min_RANGE_OUT);
  DBMS_OUTPUT. Put_line ('max_range_OUT :'|| max_range_OUT);
  end P_GET_RANGE;

  }

  I tried to call the procedure with:

  {

  declare

  V_MIN_RANGE_OUT varchar2 (30);

  v_Max_RANGE_OUT varchar2 (30);

  Start

  C_UTI_BASIC. P_GET_RANGE (TABLE_OWNER_IN = > 'PRECUBE')

  , TABLE_NAME_IN = > 'TEST_STG_TMO '.

  , RANGE_NO = > '4'

  , MIN_RANGE_OUT = > V_MIN_RANGE_OUT

  , MAX_RANGE_OUT = > v_Max_RANGE_OUT

  );

  end;

  }

  but it ends with the error:

  Error report:

  ORA-06510: PL/SQL: not supported by the user-defined exception

  ORA-06512: at "DWH_ADMIN. C_UTI_BASIC', line 2331

  ORA-00905: lack of keyword

  ORA-06512: at line 5

  06510 00000 - "PL/SQL: not supported by the user-defined exception.

  * Cause: A user-defined exception has been raised by PL/SQL code, but

  not been processed.

  * Action: Fix the problem that causes the exception or write an exception

  Manager for this condition. Or you may have to contact your

  Director of application or DBA.

  When I jump the "run immediately" just to see what is output through DBMS output here it is:

  {

  Select MIN_RID, MAX_RID in MIN_RANGE_OUT, PRECUBE MAX_RANGE_OUT. TEST_STG_TMO_RANGES where PRV = 4

  Min_RANGE_OUT:

  max_range_OUT:

  }

  the select statmetent seems OK for me, but the parameters are not met and have the value null;

  I would appreicate advice on where I went wrong here and how achieve a correct output

  Outside the use of SQL statements cr@p Dynamics (i.e. DML and not the DDL as implied by your code) and your total lack of variable bind...

  And that is your problem.  Your dynamic instruction seeks to select VARIABLES that are out of reach of the dynamic statement itself.  The IN such statements should be part of the EXECUTE IMMEDIATE for example

  EXECUTE IMMEDIATE ddl_statement INTO min_range_out, max_range_out;

• Procedure with input output and num_array sys_refcursor

  Hello

  I have to write a procedure with input of type of parameter num_array which will forward a list of IDs to the procedure and the output is sys_refcursor that will pass the id with the other columns in the table to the list of identifiers.

  operating system is the table with the id, os_name column with more than a few columns.

  create table os

  (identification number,

  OS_name varchar2 (30),

  .. .few more columns);

  I spend the os_name with id through the sys_refcursor.

  So I created the following procedure.

  num_array is a type of data defined by the user that is created as follows:

  create or replace type num_array in the table to the number;

  /

  create or replace procedure get_os_lang_dtls (num_array, id_os sys_refcursor id_num)

  is

  Start

  / * oses is the main table with id, os_name with other columns

  / * oses_gtt is the temporary table with id number data type varchar2 os_name * /.

  for indx in 1.id_num.count

  loop

  insert into os_gtt

  SELECT id, os_name

  of the operating system

  where id = id_num (indx);

  end loop;

  commit;

  Open the id_os for

  Select * from os_gtt;

  end;

  /

  
  

  I created a global temporary table with the column id and os_name.

  Insert in this table by using the id of i / p and setting os_name recovery operating system for this id in the loop.

  
  

  Then I open the exit sys_refcursor.
  

  
  

  Could someone please suggest me a better way to write the same logic?

  
  

  Thanks in advance
  

  No need of the TWG or anything too flashy here.

  Since you have a SQL type, you should be able to get away with...

  open out_ref_cursor for
  select 
  from os, table(cast(id_num as num_array)) nu
  where os.id = nu.column_value;
  

  A couple of notes apart from that. ID is not a great name for a column, why not OS_ID to be online with your OS_NAME? Second, always try to avoid use of the TWG, they are handy once in awhile, but not required nearly as often as find you them.

  A "rebate" in the casting of tables like that and their use in SQL is the cost based optimizer usually (depending on version) has no idea of how to do to optimize the query (it has no statistics on the table as it does on a table). In General, if you know that you have X items in this table, it is better to say Oracle. You can use the CARDINALITY indicator to tell Oracle about the number of lines, you expect your table to have on average. The default proposal is going to be your block size, so assuming that 8 k (standard) the estimate is going to be like 8000 items... probably not close to reality.

  See you soon,.

  HI all I would like to ask if you help me, I want to draw paths, but when I use options to mark with a pen or brush settings I lose quality when I Zoom, can someone help me with the settings for the pen?

  The work path is a vector and infinitely scalable, but when caress you, Photoshop sets the pixels on a layer following the path.  These pixels are rasterized and based and cannot be resized without loss of quality.  You have options.  If you want to enlarge the raster layer, transform the work path and stroking again.  Or work at a resolution higher, in the first place.

  Either incidentally, you can't trace a path with the pen, because it's a vector tool, and caressing is a matrix function based.
