  Thank you

  If the column was purely digital, why cast to CHAR? The OP can do everything suggested Robert Angel. My suggestion was where there was some other non-numeric values in the column that could be the reason why the column is CHAR, then using the SIMILAR filter operand would solve this problem.

  The first part of your suggesting was not necessary if the column is a numeric data type and the second part was just a repetition of what Robert.

  Yes, question
  1: is the database created?

  1. What is sure, is that your database is not registered in OCR because there are missing elements in crsctl stat res t exit for database instances.
  2. default DBCA trying to restore an RMAN backup to create a database. DBCA probably also try to connect to the new instance of the database to run scripts.
  3. you must use:

  srvctl start database -d demo
  

  This should start all database instances.

  But first try to check the DBCA logs that should be under $ORACLE_HOME/cfgtoollogs/dbca and to correct related errors.

  Hello

  It is actually quite easy.
  We knew that Oracle was looking for logsequence 1107. There is no archived log, it was deleted, or it has never generated. As you delete files, the 1st solution would be possible, BUT as there was only an instance crash so more old archived logs is not required for crash recovery. There is a need during the restoration of the old backup files, which is not our case.

  Thus, the missing log sequence has not been archived = > it is a redo log.
  To identify the required online redo log, we just to log query v$ as I suggest.

  Once the log identified file, we can recover it by specifying the redo log when you ask logsequence 1107.

  And it is on. We win! :)

• How to pre-fill a field before inserting the new record in the same block

  I'm obviously new to the forms and need help! I need to insert new records based on the lodge currently in the same block.
  
  In the block, I specify a lodge (lodge 0000) and run the query for this particular lodge. I want to insert new records
  for lodge 0000. The number of dressing room must be pre-fill with lodge 0000 and I have to do is enter the others
  provide the information.
  
  How to make a form to pre-fill the field lodge?

  Instead of global variables, why do you not use "Form settings" which are specific to your form? You can use them in the property 'Initial value' similar to global variables.

• How to filter a form with pagination?

  Hi all
  
  I converted an app to Apex 3.1 (thanks to helpful people here), but am stuck on the final form. I want to rationalize the form master / detail, ignoring the tabular report in detail. Here is (almost) a shell of what I'm trying to do:
  
  [http://apex.oracle.com/pls/otn/f?p=57085 | http://apex.oracle.com/pls/otn/f?p=57085]
  
  I would like to the selection list in the upper region to be able to filter the results in the lower region, showing a row of info at once in a form. The above example is not nearly as complex as the real form, which I am using, of course, but it should show what I'm trying to do.
  
  I've implemented the calculation for P1_EMPNO as:
  

  select min(empno)
  from "#OWNER#".emp
  where deptno like :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL

  .. .with a conditional P1_EMPNO is null. Similarly, the extraction of the line contains the same WHERE clause as above.
  
  I was turn in a circle, trying to debug this, prototyping, several formulas to test combinations of branches, SQL and such, but no luck.
  
  Did anyone done this before? I see a few semi closed discussions here, but they seem to end up in a report.
  
  TIA!

  Published by: socpres on December 1st, 2008 13:48 - minor change: changed SQL to use the code tag

  Hi rich,

  Sorry - just seen elsewhere.

  Yes, I did something like this before (although the filters were handled on a separate page, the principle would be the same thing).

  The important parts are the selection of the first record, the ID for the next and previous recordings, the conditional display of the next/previous buttons and how to set the current id EMPNO.

  1 - you already have a form on the page, the first record can be defined using a calculation of front page header that is conditional on the PK field is null and use your code as a source:

  select min(empno)
  from "#OWNER#".emp
  where deptno like :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL
  

  2. you should then have hidden items NEXT and PREVIOUS on your page. These must be calculated using calculation before header on EACH page load (IE not conditional) and using SQL queries:

  Previous (say name of the element of P1_PREVIOUS_EMPNO):

  select NVL(max(empno),0)
  from "#OWNER#".EMP
  WHERE DEPTNO LIKE :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL
  AND EMPNO < :P1_EMPNO
  

  Following (say name of the element of P1_NEXT_EMPNO):

  select NVL(min(empno),0)
  from "#OWNER#".EMP
  WHERE DEPTNO LIKE :P1_DEPT_FILTER OR :P1_DEPT_FILTER IS NULL
  AND EMPNO > :P1_EMPNO
  

  3 - your next button should depend on P1_NEXT_EMPNO is not 0 and your back button must be subordinated to P1_PREVIOUS_EMPNO is not 0

  4 - the next button should trigger a branch that sets the value of P1_EMPNO to P1_NEXT_EMPNO and your previous button must P1_EMPNO of P1_PREVIOUS_EMPNO

  5 - your branches has been triggered by the filter and Reset buttons must reset P1_EMPNO null (the calculation will calculate this new)

  Then, when the page is loaded, the first EMPNO which match the filter is determined and the previous EMPNO is automatically calculated and shown/hidden buttons as appropriate. By clicking next or previous made scroll through records and new Previous EMPNO are calculated each time. When a new filter is applied, or the page is reset, the EMPNO is cleared out and I recalculated according to the current filter.

• How to filter the file type and size during uploadind files in APEX

  Hello
  
  I was wondering how I can do to validate the size of a file, before moving in my table? I want to filter the type of file, but for this one, I think I can use regular expressions in a validation process.
  
  I don't know if there is a way to read the size of the file, even before sending it into the temporary table.
  
  Thank you
  
  Bodart

  Hi salma,

  As far as I KNOW, you need to create a validation APEX (PL/SQL Returns Boolean or returns error text), which interrogate the details of the table apex_flow_files file. Here you can get the file type and size etc.

  So just to validate and if the validation fails, then delete the apex_flow_files and riase error message file.

  Kind regards
  Hari

  P.S. Please note that, if there are other validations apex on your page, and if they fail, always apex will load the file in the apex_flow_files table. It is sensible to create a validation (PL/SQL) that will trigger (condition) when online validation errors occurred. Make sure it is the LAST commit on your page in the sequence. And here you can write code to delete the table apex_flow_files.

• How to filter the traces of tension TDMS after acquisition?

  Simple question. We have acquired a lot of electrophysiological data with express signal. We now need to filter data after the acquisition for later analysis. I can import the files TDMS tension of previous experiences, but can't seem to run the filters we used on the side of the acquisition to filter the existing traces. Is there a simple way to do this?

  -smb

  Hello Chinchilla,

  I enclose a few screenshots on how to add a step to an analog input filtering. You can select the type of filter and order too.

  

  In this screenshot you can check how to change the configuration of the filter

  

  Finally, you can access the TDMS of LabVIEW file with one of the examples of PDM. Please follow these instructions:

  1. open LabVIEW

  2 - go to help > find examples to open the Finder 'example '.

  3 - Go to Fundamentals > file Input and Output > TDMS > Standard Read and Write and select the VI named TDMS read Events.vi

  

  You will need to know the data present in the file to read correctly. For this, you can use the leading PDM Viewer VI:

  http://zone.NI.com/reference/en-XX/help/371361K-01/Glang/tdms_file_viewer/

  Or you can use the Toolbox for excel: http://www.ni.com/example/27944/en/ (allows you to transfer the data to Microsoft Excel).

  4. After reviewing the data, you will need to apply a filter. You can find the filter functions in the range of Signal Processing.

  

  Please let me know if you have any questions on this subject.

  Kind regards
