• -You also get an invalid identifier error when executing this query sql for a data model, but not in TOAD/SQL Developer?

  Hello OTN.

  I don't understand why my sql query will pass by in the data model of the BI Publisher. I created a new data model, chose the data source and type of Standard SQL = SQL. I tried several databases and all the same error in BI Publisher, but the application works well in TOAD / SQL Developer. So, I think it might be something with my case so I'm tender hand to you to try and let me know if you get the same result as me.

  The query is:

  SELECT to_char (to_date ('15-' |)) TO_CHAR(:P_MONTH) | » -'|| (To_char(:P_YEAR), "YYYY-DD-MONTH") - 90, "YYYYMM") as yrmth FROM DUAL

  
  

  Values of the variable:
  

  : P_MONTH = APRIL

  : P_YEAR = 2015

  I tried multiple variations and not had much luck. Here are the other options I've tried:

  WITH DATES AS

  (

  Select TO_NUMBER (decode (: P_MONTH, 'JANUARY', '01',))

  'FEBRUARY', '02',.

  'MARCH', '03'.

  'APRIL', '04'

  'MAY', '05'.

  'JUNE', '06'.

  'JULY', '07',.

  'AUGUST', '08'.

  'SEPTEMBER', '09'.

  'OCTOBER', '10',.

  'NOVEMBER', '11'.

  "DECEMBER", "12."

  '01')) as mth_nbr

  of the double

  )

  SELECT to_char (to_date ('15-' |)) MTH_NBR | » -'|| (TO_CHAR(:P_YEAR), 'DD-MM-YYYY') - 90, "YYYYMM")

  OF DATES

  SELECT to_char (to_date ('15-' |: P_MONTH |)) » -'|| ((: P_YEAR, 'MONTH-DD-YYYY')-90, "YYYYMM") as yrmth FROM DUAL

  I'm running out of ideas and I don't know why it does not work. If anyone has any suggestions or ideas, please let me know. I always mark answers correct and useful in my thread and I appreciate all your help.

  Best regards

  So I thought to it. It seems that there is a bug/lag between the guest screen that appears when you enter SQL in the data model and parameter values, to at model/value data.

  Here's how I solved my problem.

  I have created a new data model and first created all my settings required in the data model (including the default values without quotes, i.e. APRIL instead "Of APRIL") and then saved.

  Then I stuck my sql query in the data model and when I clicked ok, I entered my string values in the message box with single quotes (i.e. "in APRIL' instead of APRIL)

  After entering the values of string with single quotes in the dialog box, I was able to retrieve the columns in the data model and save.

  In the data tab, is no longer, I had to enter the values in single quotes, but entered values normally instead, and the code worked.

  It seems the box prompted to bind the values of the variables when the SQL text in a data model expects strings to be wrapped in single quotes, but no where else. It's a big headache for me, but I'm glad that I solved it, and I hope this can be of help to other institutions.

  See you soon.

• Select quarterly data using SQL

  All-
  
  The database version that I use is 10.2.0.4.0
  
  This is probably simple, but for the life of me, I can't understand it. I have a table of approximately 200 Codes and a table that contains millions of records that are obliterated (data are from 1995 to sysdate). I need a query for a view to be used in a report that will show you the different codes used by the employee for specific areas based on a date parameter. If they have no data for this quarter I want to still show the quarter show 0 for the number.
  
  I created this simple example. If I see someone how I can integrate this logic in what I do.
  
  SQL for the test data:
  create the table bunch_of_codes
  (id_code number (12) primary key,)
  Description varchar2 (10));
  
  insert into bunch_of_codes
  values (1, 'APPLE');
  
  insert into bunch_of_codes
  values (2, 'ORANGE');
  
  insert into bunch_of_codes
  values (3, 'GRAPE');
  
  create the table bunch_of_data
  (id_code, number (12),)
  date of activity_date,
  CONSTRAINT data_id_code
  FOREIGN KEY (id_code) REFERENCES bunch_of_codes (id_code));
  
  INSERT INTO bunch_of_data
  VALUES (1, to_date('4/12/2011','MM/DD/YYYY'));
  
  INSERT INTO bunch_of_data
  VALUES (1, to_date('6/1/2011','MM/DD/YYYY'));
  
  INSERT INTO bunch_of_data
  VALUES (3, to_date('1/15/2011','MM/DD/YYYY'));
  
  INSERT INTO bunch_of_data
  VALUES (3, to_date('4/17/2011','MM/DD/YYYY'));
  
  INSERT INTO bunch_of_data
  VALUES (3, to_date('11/11/2011','MM/DD/YYYY'));
  
  COMMIT;
  
  What I see when I run the SQL statement is:
  DESCRIPTION QUARTER COUNTY
  ----------- ------- -----
  APPLE 1 0
  2 2 APPLE
  APPLE 3 0
  APPLE 4 0
  1 1 GRAPE
  1 2 GRAPES
  GRAPES 3 0
  4 1 GRAPE
  ORANGE 1 0
  ORANGE 2-0
  ORANGE 3 0
  ORANGE 4 0
  
  I need each printed code without worrying if it was not used. If it has not been used, I want to still see each quarter but show 0 for count.
  
  For this example, I can run this SQL to join the data:
  Select c.description,
  to_char(d.activity_date,'Q') quarter,
  Count County (d.id_code)
  of bunch_of_codes c,.
  bunch_of_data d
  where c.id_code = d.id_code
  C.description group, to_char(d.activity_date,'Q')
  order of description, quarter
  
  But if it is not no matter how much detail for the quarter then I don't get a row of data. I tried all sorts of things, but nothing seems to work.
  
  Please help if you have any ideas.

  Hi MLBrown,

  Here's a query that gives what you asked.
  Note: My table bunch_of_data has three lines that you have published, more a fourth line (the activity_date of this row is April 12, 2010, in the format DD-MON-YYYY).
  To account for the response you gave to the question of Etbin, a column Y (for data year) is included in the output. In this output, there is for the year, Q for the quarter and the total for the count.

• History of SQL do not sort by date; new format of TS v4?

  I was afraid that my history of SQL was not accumulating after upgrade, as it seemed not as I expected.

  
  

  I generally sort descending timestamp, but I find that hold since the installation of the version 4.0 production this different format of timestamp on the history of SQL took, ignoring the NLS settings that I put in my preferences (which were not those default to my territory and language, incidentally).

  I migrated all my settings from the previous installation, I had... .sqldev4 ea3.  previous migrations from v3 to v4 ea1 to v4 ai2 to v4 ea3 ever disturbed my history of SQL.

  Now my recent entries are buried in the history of SQL and show no longer on top, and sorting by date seems erratic, it is impossible to see a chronological order of the executed SQLs before and after migration.

  Y at - it shaped a command to put the SQL history timestamps or I have to go spelunking in the xml files to change a setting?

  Curiously,.

• Shows SQL ID, OEM, but says: * SQL text not available *.

  I'm a bit confused on this and was hoping that someone can help you.
  
  I use DBConsole to an Oracle 11.2 (on Solaris 10) database.
  
  I see really high momentary ' * + tips + * ' in an activity greater than about 20 to 30 minute intervals.
  When I try to understand which SQL is causing the Spike, I drag the section shaded the area containing the Spike and look at all the SQL statements during this period.
  I first try to look the SQL statements by highlighting, or by clicking on the entries in the column of ID of SQL in SQL from the top (bottom left of the page).
  Then I copy and paste the statements in my sqlplus session and see if it causes any sort of spike that I followed in another window OEM looking at key activities.
  Usually, I don't not even a blip on the radar, so I'm not find the SQL statement that causes the spikes.
  Sometimes, however, when I hover over an ID of SQL, it does not show the SQL statement and instead of it shows just the words: [SQL ID].
  
  Then, I run a report of ASH for the 5 minute window of the shaded area containing the Spike.
  When I look at the "full list of SQL text" ASH report, I found an entry or the Scriptures have to say: * SQL text not available *.
  
  So then I try to select sql_text from v$ sqlarea where sql_id = «...» "(whatever this sql_id is), and I get no rows found.
  for example,.

  SQL> select sql_text from v$sqlarea where sql_id = '99mjdv0hkh5km';
  
  no rows selected

  In fact, when I try other sql_id, I don't get them either and I guess that's because they are already old v $ sqlarea.
  If I check the v$ sqlarea for up-to-date notifications, they work fine.
  So, the first thing, what controls the duration of v$ sqlarea (pool size)?
  
  Then I chose to DBA_HIST_ACTIVE_SESS_HISTORY and it displays the information related to the ID of SQL, but of course, it does not show the sql text.

  If your application uses literals, SQL is simply disappeared from sqlarea until you know.

  Although it will certainly be when it is running, then maybe you should look at the right time :)

  However if I submit this a subsequent update trigger code in my form, the code runs without error, but my email is never received (the same parameter values would be conveyed to this trigger):
  

  begin
  
  -- Submit the email notification in the background so as to not slow down the screen while saving.    
  dbms_scheduler.create_job (  
       job_name            => 'IMMEDIATE_JOB',  
       job_type            => 'PLSQL_BLOCK',  
       job_action          => 'begin TTMS.dropperVacationConflict_Notify (:dropper_vacations.dropper_id, :dropper_vacations.begin_dt, :dropper_vacations.end_dt); end;',  
       number_of_arguments => 0,  
       start_date          => sysdate +1/24/59, -- sysdate + 1 minute  
       enabled             => TRUE,  
       auto_drop           => TRUE,  
       comments            => 'Immediate, one-time run');
  end;     

  Any ideas why this might be happening?

  Oh, and of course after that you have a lot of other type conversions that may fail.

  Let's take a look. You propose the work like this:

  job_action => 'begin TTMS.dropperVacationemailurl_new ('||p_dropper_id||','|| p_begin_date||','||p_begin_date||'); end;', 
  

  p_begin_date and p_begin_date (why 2 times start date? in any case). are concattenated in a varchar2, so a type conversion occurs; the date format used is the nls_date_format of your session. If this will result to

  begin TTMS.dropperVacationemailurl_new (1234,01-FEB-11,01-FEB-11); end;
  

  now take this block and run it in SQL * more. I can see miles it won't work, because the date data types that you pass are not yet passed as strings.
  It might work, if you pass them as strings:

  begin TTMS.dropperVacationemailurl_new (1234,'01-FEB-11','01-FEB-11'); end;
  

  but then I say I just change the nls_date_format of my session and break your code, because the implicit conversion from varchar2 to date will fail.

  the very ugly solution for this should be

  job_action => 'begin TTMS.dropperVacationemailurl_new ('||p_dropper_id||',to_date('''|| to_char(p_begin_date,'dd-mon-yy')||''', ''dd-mon-yy''),to_date('''|| to_char(p_begin_date,'dd-mon-yy')||''', ''dd-mon-yy'')'); end;'
  

  If you have a tank that is converted to a date that you go to the external procedure which then gets converted to a tank which then gets converted to a date once again. My head hurts. If simply insert you dates into a table and select the dates in dropperVacationemailurl_new instead of 10000 conversions and pass them you wouldn't make 10000 converts and don't care the date format.

  see you soon

• Strategic review of using Pro * C package vs embedded SQL Select

  Hello
  I have an old application package.procedure that I'm looking using proC call to get the necessary data through Oracle Package.Procedure. Real call to the package see below, 1 parameter, released as a REF Cursor, SQL Select is simple-nothing fancy.
  
  I was wondering what might be the benefits (if any) to do that instead of coding real SQL Select into my proC code?
  In the case of any change, you need to change the proC and body package, rather than just do it in place if used directly?
  
  Source control, PM, nice structure inside of the Oracle, departmental approach just? Everyone at least one list?
  
  Appreciate your opinion, thank you all.

  Hello

  This is not so much a direct answer to your question, but this thread AskTom discusses some of the advantages to using code in the database and the client.

  http://asktom.Oracle.com/pls/asktom/f?p=100:11:0:P11_QUESTION_ID:30732069210515

  If search you around you can find several other discussions about the same thing.

  The centralization and reusability are two factors that lead me to focus on the code that is stored in the database.

• Need help with SQL SELECT

  Hello
  
  I have a table named WORK_CODES
  There only a single column CODE
  The CODE values are
  YES
  NO.
  A
  B
  C
  
  I get a connection variable: var1
  If: var1 is TRUE = > YES, I'll be back
  If: var1 is NOT TRUE = > I would alternate record in the WORK_CODES table.
  
  The tricky part is that it must be managed in a SQL query.
  Any help on this is appreciated.
  
  Thank you
  Pradeep

  
  The first problem I see is that SQL does not support the Boolean data type. Then you must consider changing the data type of your variable binding.

  Assuming that you change it to integer where 1 = 0 = false and true, you can do
  

  I guess I misunderstood. You can do it simply.

  select *
    from 
   where (:var = 'TRUE' and code = 'YES') or (:var = 'NOT TRUE' and code != 'YES')

• NULL in PL/SQL SELECT statement..

  Hi all
  
  I need to use as a result of a SELECT statement in my function to get PCODE from the table. Cur_rec here. CODE comes from cursor that runs before the declaration.
  
  SELECT PCODE in v_pcode TABLE_XYZ where CODE = cur_rec. CODE and PCODE = 'VIEW '.
  
  
  Now the problem is the part of the CODE has all the information in the table TABLE_XYZ. In this case, it triggers an error NO_DATA_FOUND. To solve it, I can put a part of the EXCEPTION and handle it. But I think in another way...
  
  If there is no data for a CODE, the default value of v_pcode would be 'No Code'. I tried to use the NVL function, but it does not work here as a SQL SELECT statement.
  
  Can someone give an idea how to achieve this?

  Hello

  declare
    ...
    v_cnt number;
  begin
    SELECT count(*)
         into v_cnt
        from TABLE_XYZ
      where CODE = cur_rec.CODE
         and PCODE='SEE';
    if v_cnt=0 then
      v_pcode = 'No code';
    else
      v_pcode = 'SEE';
    end if;
  end;

• SQL does not work

  I posted this already, but I can't so I'm posting again so apologies...
  
  I downloaded Oracle Express. I used the utilities tab and downloaded a file. I can see the file with "select * from all_tables ' and I can't
  see that I am the owner. I have s/n privs, and using the object browser, I can see the data and and I have granted all privileges to the public.
  Although I can see the table of the dictionary with SQL, and object browser, I am the owner; but, SQL will not allow me
  describe the table
  Select from the table
  even remove the table, so I can recreate another way.
  
  All I get never the SQL tab or BACK SQL command line is "ORA-00942: table or view does not exist '- but it does not exist under my ownership and all privileges have been granted on the table. What's wrong? Thank you... Richard ([email protected])

• Tricky SQL - is possible using just SQL and not of PL/SQL

  Hi all
  
  Here's my data
  
  create table experience (exp_id number (10), exp_name varchar2 (20), root_exp_id number (10));
  insert into a values (642, 'Test', 5172) experience;
  
  create table experience_node (exp_node_id number (10), exp_node_type_id number (2));
  insert into experience_node values (5172, 1);
  insert into experience_node values (5173, 2);
  insert into experience_node values (5174, 2);
  
  create table experience_connector (exp_conn_id number (10), exp_conn_type_id number (2), exp_node_id number (10), parent_exp_node number (10));
  insert into experience_connector values (1, 5173, 4287 5172);
  insert into experience_connector values (4288, 2, 5174, 5173);
  insert into experience_connector values (2, 5175, 4289 5174);
  
  When you run these queries:
  
  Select parent_experience_node_id
  of experience_connector
  where experience_node_id = 5175;
  
  Select parent_experience_node_id
  of experience_connector
  where experience_node_id = 5174;
  
  Select parent_experience_node_id
  of experience_connector
  where experience_node_id = 5173;
  
  Select parent_experience_node_id
  of experience_connector
  where experience_node_id = 5172;
  
  gives 5174, 5173 and 5172 and null. exp_node_type_id = 1 and exp_node_conn_type_id = 1 indicates that it is at the root. Hope my explanation is useful. Is what I'm trying to get - to get the big concession to 5175 grandparent who is 5172. Is it possible to do it with SQL?
  
  Thank you very much for you help.
  
  Best,

  Well, you say that you need to root, not great great grandparent? If so, use:

  SQL> select  parent_exp_node
    2    from  experience_connector
    3    where connect_by_isleaf = 1
    4    start with exp_node_id = 5175

• Unable to connect to the selected mobile data Simulator service

  First of all, let me say that I am a newbie with BlackBerry and simulators.

  I just downloaded 9630_Verizon and 9630_Sprint simulators as well as the MDS Simulator package. I start the MDS Simulator and the DOS window opens and seems to work very well. I start be 9630 simulators and while it seems to work, when I click on the button of the browser and try to go to any web page, I get:

  Unable to connect to the selected Mobile Data Service, please try again later.

  The version of the 9630 Simulator is 2.12.0.47

  The MDS Simulator version is ' SCM 4.1.4.19 19 2007/07/10»

  I can connect to the MDS Simulator using my browser of desktop connection to localhost: 8080. Statistics show all values of zero, so it seems that the 9630 is not yet connect to the Simulator. Is there a configuration file somewhere that I have to change to make it work?

  After that I posted this, I continued to search the forums of possible solutions. One recommendation, I found was to delete the files ".dmp" and restart the device Simulator. That did the trick, things work now.

• reset_image_prefix. SQL does not work

  Hello

  My DB has two instances with two different versions of the top charge. One is the version 4.1.1 (works well) and I decided to upgrade the other 4.1.1 to 4.2. I created a new location in the httpd.conf file entry in my case of OSH to point to the new instance 4.2 referencing a new Alias image on the server. When I installed APEX 4.2 I showed the images the New Alias directory setting "i42' but it does not work. Applications always refer to is

  I ran the script reset_image_prefix.sql with /i42/ as an input parameter, but the applications are always reference/i /.

  There was a similar discussion in October 2012 and Patrick Wolf wrote on bug # 14785456.

  But the BUG seems to be fixed?

  After executeing the script Iget:

  SQL > select text from dba_source where owner = 'APEX_040200' and lower (name) = "wwv_flow_image_prefix";

  TEXT

  ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

  package wwv_flow_image_prefix

  is

  constant g_image_prefix VARCHAR2 (255): = ' / i42 / ";

  end wwv_flow_image_prefix;

  4 selected lines.

  Is there a solution?

  Kind regards

  Carola

  Hi Carola,

  What exact version of APEX 4.2 do you use? Are you using the latest 4.2.2? Because it includes the hotfix that you referenced. After installation of this version or the patch installed, it will automatically erase all the prefixes image-level asks if they are identical to the current instance image prefix. So in your case, you should set the prefix image back to / i /, install the hotfix and then reset_image_prefix again to set the parameter instance/i42.

  Joel has some useful information on this blog (YABAOAE) yet another Blog about Oracle Application Express: prefix of Image Exchange in Oracle Application Express 4.2.2

  Some background info on reset_image_prefix.sql. Who has never changed the image prefix used in applications, only the prefix of image for our application Builder.
