• SQL query simple SQL Developer takes, the wizzard of XE does not work

  Hello everyone
  
  I wrote this simple query that developer SQL works well, but when I try to run a report based on this sql query, it tells me invalid sql statement. It's true, maybe it's not valid because this IF clause in there... but Developer SQL seems to be very tolerant or includes more...
  
  I wrote this is because obviously if there is no Boss, ie = 0 then I would get an error when it division by 0, so I put that 0 just for selecting the right

  Ok. This should work:

  Select company, zip code.
  -case when count (staff)! = 0 here end sum (Boss/staff)

  Group of company, zip code

  If this does not work, could you please explain, how your table looks like?

• Clarification of the SQL query in 2 day + Guide APEX

  I worked through the Oracle Database Express Edition 2 day + Application Express Developer's Guide, and try to decipher the SQL query in Chapter 4 (building your app).

  The code is:

  SELECT d.DEPARTMENT_ID,

  d.DEPARTMENT_NAME,

  (select count (*) from oehr_employees where department_id = d.department_id)

  "Number of employees", he said.

  substr (e.first_name, 1, 1) |'. ' || Select 'Name Manager',

  c.COUNTRY_NAME 'place '.

  OEHR_DEPARTMENTS d,

  E OEHR_EMPLOYEES

  OEHR_LOCATIONS l,

  C OEHR_COUNTRIES

  WHERE d.LOCATION_ID = l.LOCATION_ID

  AND l.COUNTRY_ID = c.COUNTRY_ID

  AND e.department_id = d.DEPARTMENT_ID

  AND d.manager_id = e.employee_id

  AND instr (superior (d.department_name), superior (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0)

  I don't know exactly what is happening in the last line. I think I understand what the different functions but I'm not clear on the use of the: P2_REPORT_SEARCH string.

  What does this string? This code simply checking that d.department_name isn't NA?

  I have SQL experience but am not very familiar with the Oracle PL/SQL implementation. Can someone please give me a brief breakdown that check is doing in the context of the overall query? The application seems to work even if the conditional statement is not included.

  Thank you.

  Thanks for the reply. I apologize if the information I added was incomplete. The code came from the day 2 + Application Express (version 4.2) Developer Guide.

  In the section 'your own Application of 4 Buuilding' https://docs.oracle.com/cd/E37097_01/doc.42/e35122/build_app.htm#TDPAX04000 , they describe the creation of a report

  page that includes the "manager_id" and 'location_id '. The SQL query, I pasted above extracted from the data in other tables to substitute the real 'name of the Manager' and 'rent '.

  for the corresponding ID values. It makes sense, and the part of the SQL query that explicitly doing this makes sense.

  However, given that the document is a guide for the development of the APEX, I guess the command:

  AND instr (upper (d.department_name), upper (nvl (:P2_REPORT_SEARCH,d.department_name))) > 0

  done something valuable, and I do not recognize what is exactly the value.

  From a practical point of view why would I need to include this conditional statement?  Which only added to the application?

  Looking at the guide in question, it is clear that the

  AND instr(upper(d.department_name),upper(nvl(:P2_REPORT_SEARCH,d.department_name)))>0
  

  the line is completely unnecessary in the context of this tutorial, and it can be removed. The search in the tutorial app page is implemented by using a report filter interactive rather than a P2_REPORT_SEARCH element, which does not seem to exist at all. (It's a quirk of the APEX that bind variable references to non-existent items are replaced with NULL silently rather than exceptions). I thought that perhaps it would be legacy code a version of the tutorial prior to the introduction of interactive reports at the APEX 3.1, but I can't find explicit instructions to create such an element of filter in the 3.0 tutorial. I guess it must have been automatically generated by the application wizard when you create a standard report page.

  If you do not want to see the effect he would have (as described in the post above), leave it in the source report, add a text element of P2_REPORT_SEARCH, and a button "submit" on page 2 and experimenting to find different values of the element and clicking on the submit button...

• Pool pane there problem with long sql query?

  Hello

  I use Jdeveloper 11.1.2.2.0

  In the application I'm developing, there is a long sql query to call (it's a function from a package, which may take a few minutes to run) and I want to display a progress bar for the user.

  The progress bar component is a "progress indicator" and the percentage of achivement is refreshed by a component 'pool' with 1-second interval.

  The two components are connected in a javabean.

  The function with the sql query is the javabean too.

  To run the sql query that is long on background I am calling from a thread, and the pool component get the advancement of the percentage of a pipe filled with the sql function.

  If the function to run is just a long loop of java operations the progress bar works fine, but if I put my long sql query instead, stop listener pool should be performed to stop long, s sql queryo progress are updated only at the end of the long sql query.

  You have any ideas?

  Thank you

  Thanks for your replies. Unfortunately, it was not the solution to my case, sql procedures to block the entire application while ADF awaits them at the end...

  To solve my problem, I finally used a PL SQL Job to call my sql procedure (dbms_job.submit).

  The application is released right after the call and the component of the pool is not more secure!

• Dynamic SQL query in the DB adapter

  Hello
  I want to use the following custom SQL query in the DB adapter:
  
  SELECT EMP_ID, EMP_NAME, EMP_LOCATION FROM EMP WHERE EMP_ID IN (#iNPUT_PARAMETER)
  
  the problem I'm facing is that I don't know at the time of the development that EMP_ID how much will be passed to the process so that I can not use the input parameter specific number. I cannot use it IN the query within which statement I concatenate all the EMP_ID separated by comma and passed under INPUT_PARAMETER, but when running, he read the full concatenated string as a single string rather than identify them as a list of different: with comma separation. could someone help me in this case
  
  Thank you
  Sunil

  Use the following query with two parameters. Build the string with delimiter when running and pass this string and delimiter to query... (in this example, the input value would be the same for both Delimiter1 and Delimiter2.)

  Select * from EMP WHERE deptno IN (SELECT SUBSTR (STRING_TO_TOKENIZE, DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1), INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL)-DECODE (LEVEL, 1, 1, INSTR (STRING_TO_TOKENIZE, SEPARATOR, 1, LEVEL-1) + 1)) FROM (SELECT #StringToTokenizer | #Delimiter1 AS STRING_TO_TOKENIZE, #Delimiter2 AS DELIMITER FROM DUAL) CONNECT BY INSTR (STRING_TO_TOKENIZE SEPARATOR) ((, 1, LEVEL) > 0)

• Any difference between the separate function and aggregation in sql query cost?

  Hello
  I've run many models sql stmts - such as:
  one) using a single table
  (b) using the two tables, using simple joins or outer joins
  
  but I didn't notice a difference in sql stmts in cost and implementation plan...
  In any case, my colleague insists on only using the aggregate function is less expensive compared to
  separate... (something I've not confirmed, that is why I believe that they are exactly the same...)
  
  For the situation described above under 1 sql... We could for example use
  

  select distinct deptno
  
   from emp

  select count(*), deptno
  
   from emp
  
   group by deptno

  select distinct owner, object_type from all_objects

  select count(*), owner, object_type from all_objects
  
  group by owner, object_type

  Have you ever found no difference between the two...?
  
  Note: I use Ora DB 10g v2.
  
  Thank you
  SIM

  Alexandre Gelin says:
  function separate and aggregation are for different uses and can give the same result, but if you use the aggregate function to get the separate records, it will be expensive...

  really? I find them almost identical to 11g. Actually GROUP BY is almost always more fast for me in the old days.

  This applies mainly to the older oracle versions http://www.oracle.com/technology/products/rdb/pdf/distinct_derivedtables_groupby_sort_tech_article.pdf

• Tables and SQL query

  Hello
  
  I post this question for clarification. I have a report that is based on a SQL query area.
  
  Place automatically APEX sql in the tables, all THE results of a query if it is in a region of report? Or y at - it a step that the developer must do to retrieve the columns of the sql query in a table.
  
  I'm working with checkboxes, and I read up on top of the api APEX_APPLICATION. This part is still unclear.
  
  Your comments would be appreciated!
  
  Keisha

  Hi Keisha,

  You should have a read of: [http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/check_box.htm#CHDHFACG] that explains the use of checkboxes on the reports.

  I guess the 'picture' you refer to are APEX_APPLICATION. G_F01 up APEX_APPLICATION. Paintings of G_F50? If so, they are built when you submit the page and are based on elements with attributes of 'name' of 'f01' up to 'f50' in the HTML tags. You don't need to do anything beforehand to create these, which is done automatically for you by the Apex. But, notes, however, that only the checked boxes are presented with a page - so if your username is checked, say, 3 of the 10 boxes, table will contain only 3 points not 10 (with each element of the table that contains the attribute 'value' of a checkbox).

• Failed to parse the SQL query by user

  Hi all
  
  in my application, I have a piece of text with a button "submit". In this article, I type a name and a report after the element region show me the result (s). This works for all my users (> 2000) perfectly, but that users become an error in the area of the report:
  
  Failed to parse the SQL query:
  ORA-01403: no data found
  
  We try this with the same searchstring on the same computer/browser. If I connected the result is ok, if the logged on user, the error message appears. If I try this on the user's computer with me connected, ok result. If the user try this on another pc, error results.
  
  I have a production and a developer workspace. In the developer workspace the user can try this perfectly without errors. That in the space of productive work, clear the error.
  
  The SQL-Select in the ist verry simple reprirt:
  
  Select id
  name
  raum
  table
  where instr (upper (name), upper (:P60_SEARCH)) > 0
  
  However, all users can use this search box with report perfectly, only this one user has the error. There is no restrictions on this point or a State.
  
  Can someone help me?

  Hi Carsten,

  I don't think that there is a way to do it.

  Could you please mark the correct and useful answers in this thread? Otherwise I'll never get near Andy ;) :)

• Œuvres SQL query to MS SQL Server 2008, but not when you use the database kit

  I have this SQL query:

  DECLARE TABLE (@DataTypeTable)
  Name varchar (128).
  TypeID INT)

  -Add comma delimeted type data in the temporary table names
  INSERT INTO @DataTypeTable (name)
  SELECT * from WhatWeShouldDoRead.func_Split (@DataTypeTrimmed, ',')

  SELECT the name OF @DataTypeTable

  That takes a comma delimited by the string and returns the string as a table.  It works correctly in Microsoft SQL Server Management Studio.  When I run this as a stored procedure I return nothing.  There are no errors, SQL or otherwise.  I checked that I am connected to the correct database and the stored procedure is responsible without changing any error chain which is reported of this stored procedure (that code is not shown in the example above).  Has anyone seen this problem before, or have experience with SQL/Labview interfaces to tell me what I am doing wrong?

  Thanks in advance.

  Hello

  You have two cases:

  (1) connect to the database with string (link a string of connection information), and then type something like this:
  Driver is SQL Native Client;. Server = IP. Add.re.SS; UID = username; PW = *** ; Database = MyDatabase (depends on your database)

  (2) use a UDL file (you can configure it to connect to your database, with specific format). Remember that the connection is successful with test button.

  There is a UDL file that you can edit here: C:\Program NIUninstaller Instruments\LabVIEW 2010\examples\database\Labview.udl

  Edit: The connection dropped, you can set the path to an mdb file, and I think you can give the path of your accdb file.

  Kind regards

• SQL query for empty string

  I am trying to execute the following SQl query, SELECT * failure WHERE ID = '123 ' AND RepairAction =' '; using the DB tools run Query.vi. This query never find record in my database. My database contains a record where the registered ID contains the value '123' and the RepairAction field is an empty string. If I remove the declaration 'AND RepairAction' ';' my query text, the record is found. I think my problem is that I do not use the correct syntax to describe and an empty string. I tried the following: "," ",""," "and NULL as empty and none of these work string arguments.

  I was hoping someone might be able to tell me what the correct syntax is an empty string or if there is another approach that I take.

  Thanks in advance for your help,

  Jim,

  Just to be sure, have you used 'is' instead of '=' in this command?

  This makes all the difference in this command.

• Support of SQL query: what tasks are Sunday from 07:00 - 12:00

  Hello tide Admins.

  I need to do a SQL query that can give me a list of jobs that are running on a given (Sunday) day from 07:00 - 12:00.  Our environment is not a maintenance window.  Therefore, whenever there is application of patches or upgrades, it causes more work and risk of failure of the tide tasks.    By moving jobs over the period from 07:00 - 12:00 Sunday, patch can be completed without disrupting the calendar.

  Im not the best at the SQL script and can not get my script to work. any help would be great. Here's what I have so far.  I get the error ' could not find identifier multi-player jobmst.jobmst_name.  IM using Tidal 6.0.3 with SQL for DB Admeral table.

  SELECT dbo.jobdtl.jobdtl_id, dbo.jobmst.jobmst_prntname, dbo.jobmst.jobmst_name

  FROM dbo.jobdtl INNER JOIN

  dbo.jobmst ON dbo.jobdtl.jobdtl_id = dbo.jobmst.jobdtl_id

  WHERE (dbo.jobdtl.jobdtl_fromdt > 14 September 2016 06:00 ') AND (dbo.jobdtl.jobdtl_fromdt< '09/11/2016="" 012:00:00="">

  GROUP OF dbo.jobdtl.jobdtl_id, dbo.jobmst.jobmst_prntname, dbo.jobmst.jobmst_name

  Hi Jeff

  The time window from the jobdtl returns only jobs that have an early start time and windows of time from beginning to the end, so there may be some tasks which are not time bound but have dependencies on other jobs, variables, etc.

  Here are the 2 SQL queries against the table jobrun and jobmst:

  -The list of jobs that took place last Sunday between 07:00 and 12:00

  SELECT jobmst.jobmst_prntname, jobmst.jobmst_name, jobrun.jobrun_time FROM jobrun
  JOIN jobmst on jobrun.jobmst_id = jobmst.jobmst_id
  WHERE jobrun.jobrun_time > = 9/11/2016 07:00 ' and jobrun.jobrun_time<= '9/11/2016="" 12:00="">
  ORDER BY jobrun.jobrun_time

  -For a list of jobs that are scheduled to run on Sunday to come between 07:00 and 12:00

  SELECT jobmst.jobmst_prntname, jobmst.jobmst_name, jobrun.jobrun_esttime FROM jobrun
  JOIN jobmst on jobrun.jobmst_id = jobmst.jobmst_id

• Looking for a SQL query to retrieve callvariables + ECC to a RESULTS of SCRIPT EXECUTE (translation VRUS)

  Hi team,

  I'm looking for a SQL query check data (ECC + CallVariable) due to a RESULT of SCRIPT EXECUTE when you ask an external VRU with a translation route to VRU with a 'run external Script '.

  In my view, that the data are analyzed between the termination call detail + termination call Variable.

  If you have already such a SQL query I would be very grateful to have.

  Thanks and greetings

  Omar,

  respectfully, shorten the interval of a day might not be an option for a history report ;-)

  I recommend to take a look at the following SQL query:

  DECLARE @dateFrom DATETIME, @dateTo DATETIME

  SET @dateFrom = ' 2014-01-24 00:00:00 '

  SET @dateTo = ' 2014-01-25 00:00:00 '

  SELECT

  TCV. DateTime,

  TCD. RecoveryKey,

  TCD. RouterCallKeyDay,

  TCD. RouterCallKey,

  VME. EnterpriseName AS [ECVEnterpriseName],

  TCV. ArrayIndex,

  TCV. ECCValue

  OF Termination_Call_Variable tcv

  JOIN THE

  (SELECT RouterCallKeyDay, RouterCallKey, RecoveryKey IN Termination_Call_Detail WHERE DateTime > @dateFrom AND DateTime)< @dateto)="">

  THE tcv. TCDRecoveryKey = tcd. RecoveryKey

  LEFT OUTER JOIN Expanded_Call_Variable VME ON tcv. ExpandedCallVariableID = VME. ExpandedCallVariableID

  WHERE the tcv. DateTime > @dateFrom AND tcv. DateTime<>

  With variables, you can set up your code (for example, you could write SET @dateFrom =? and let the calling application to fill in the DateTime for you).

  In addition, join two large tables with all the lines, as you did (TCD - TCV) is never a good option.

  Another aspect to consider: all the ECC is actually arrays (always), is not good to leave aside the index value (tcv. ArrayIndex).

• DA on updatable report items Sql query using the class

  Request Express 4.2.5.00.08

  10-11 g Oracle

  I have a page, so it has a link/button when he clicks then modal region will appear. Modal region has a as a table (Type SQL Query (updateable report)). All work very well so far.

  
  

  However, I've now added some complex things.

  for example. My region is based on the query of SQL Type (editable report).

  SELECT id, name of family, Traghetti, area, d_date, start_time, End_time, displacement, role of table where id =: P10_ID;

  I can also add a new line of course.

  My problem is, (point) Shift display based on the value of Start_Time point) and so I made sure the class for two items.

  for example, Start_Time (' class = "st_tm" ') and Maj ('class to = "Shift_time" '). Start_Time is based on (LOV) and shift is off the point in the sql query, but change the Start_Time.

  And now, I created the DA.

  1. event: change

  Selection type: jQuery Selector

  jQuery Selector: .st_tm

  Condition: No.

  1. action: set value

  Set type: Expression Javascript

  The JavaScript Expression: $(this.triggeringElement) .val ();

  The element affected: P10_X1 (it is a hidden item)

  2. action: Plsql Code

  Code: start to null; end;

  Page items to submit: P10_X1

  3. action: Plsql Code

  Code: start

  If: P10_X1 between '03' AND '11' then

  : P10_X1: = 'EARLIES ';

  elsif: P10_X1 then '12' and '18'

  : P10_X1: = 'LATES ';

  on the other

  : P10_X1: = 'NIGHTS';

  end if;

  end;

  Page items to submit: P10_X1

  NOW another DA

  Event: change

  Article (s) P10_X1

  Condition (in list)

  value (HASTY, LATES, NIGHTS)

  Action:

  Set type: Expression Javascript

  The JavaScript Expression: $(this.triggeringElement) .val ();

  Affected item:

  Selection type: jQuery Selector

  jQuery Selector:. Shift_time

  Well, I look forward all the above work well, but I'm having a problem.

  If I have more than 1 lines on a modal region and if I change the Start_Time value for a row then MAJ (point) is changing but he effect on all lines.

  I want, if I make the changes on the line line # 2 while only 2 # MAJ (point) must be not performed any other lines?

  Help, please!

  Kind regards

  RI

  I found the solution me thank you.

  I removed all the DA mentioned above and created a new.

  1. event: change

  Selection type: jQuery Selector

  jQuery Selector: .st_tm

  Condition: No.

  Scope of the event: dynamic and light on page load.

  Action (Javascript code)

  ROW_ID = $(this.triggeringElement).attr('id').substr (4);

  If ($(this.triggeringElement). val() > = 03 &. val() $(this.triggeringElement))<= 11)="">

  .Val ('EARLIES') $(«#f11_» + row_id);

  }

  ElseIf ($(this.triggeringElement). > 11 val() & $(this.triggeringElement). val())<= 18)="">

  .Val ('LATES') $(«#f11_» + row_id);

  }

  ElseIf (. val() > $19 (this.triggeringElement)) {}

  .Val ('NIGHTS') $(«#f11_» + row_id);

  }

  also created another DA because I have a disabled report items.

  Event: before the page is sent.

  $('_:_disabled').removeAttr ("disabled");

  and finally created manual process of DML for tabular and everything works fine. (Insert, Update, and delete).

  Kind regards.
