ADF 11 g: problem with cascade delete

• What way to go with cascade delete

  Hello
  I must compose intellegent delete to table with PK - FK constraints (3 tables involved in this relationship), these constraints always without "delete cascade > but it could be fixed as it still in DEV." I'm curious to know how to do, then it will work in the best way.
  I am bit new to Oracle and any option cascade on DELETE is not found, so confused how it works in Oracle, what I need to ALTER first letting fall the constraints and then delete the tables one by one, or...
  I also read that read on www on some problem with < on delete cascade >, while it brings more confusion and attention...
  
  I enjoy info or pointer to any good place to learn or any good sample.
  What is best solution starting with DB at the end DELETE definition.
  
  Thank you all very much.

  If you wanted to do a removal of the waterfall, you need to delete and recreate the foreign key constraint to specify that

  http://laurentschneider.com/wordpress/2007/08/on-delete-cascade.html

  In general, however, strongly hate the delete cascade option. I would have much preferred that the procedure that removes data from the company mother (you don't have such a procedure, right?) explicitly delete data by children (by calling another procedure in a different package). This makes it much more obvious for prospective developers what is happening, and what makes it much less likely that a deletion will have a perverse effect.

• Problems with changing/deleting of an adjustment layer

  First post here and I'm going a little crazy!  I use the latest version of CS5.

  I have some photos that I am currently having my subjects in color with the rest of the image in black and white.  This is a common trend, I do it with a lot of my photos, but for some reason I can't seem to remove the selected area, I created with the Quick Selection tool or the lasso tool.

  For you show how I always have done:

  I opened the image (these are jpg files) - the background layer is in color

  I add a hue/saturation adjustment layer.

  I adjust the saturation of the black and white layer.

  In general, I use the quick selection tool to highlight my topic, I want to be in color.

  When the subject is completely highlighted, I click on 'remove' and I see in the layer mask, the selected area black and my topic is the color of the background layer.

  I started to do that today and went through a handful of JPEG images using this same method, but now all of a sudden I try and do it, but when I click DELETE nothing happens and the layer mask is totally white without any modification whatsoever.

  Please please please help.  I have no idea why this method just stopped working all of a sudden.  I keep looking on Google to find similar problems, but does not.

  Maybe your background color is not black.

• ADF Mobile Browser: problem with rowSelection = property 'Single '.

  Hi all

  I use jdev 11.1.1.5.0 version.

  I'm setting up browser mobile ADF application. in my case, I created two pages jsp (pronounced on mobile). on the first page, I slipped master vo and on the second page I drag detail vo.

  and rowSelection value = "Single" another property in VO. master so when the user select table main line radio button, and then click the order link go to the details page and vo display detail record according to master vo.

    <tr:table value="#{bindings.PayDepartmentView1.collectionModel}"
                    var="row" rows="#{bindings.PayDepartmentView1.rangeSize}"
                    emptyText="#{bindings.PayDepartmentView1.viewable ? 'No data to display.' : 'Access Denied.'}"
                    width="100%" horizontalGridVisible="false"
                    selectionListener="#{bindings.PayDepartmentView1.collectionModel. makeCurrent}"
                    rowSelection="single">
                    
            <tr:column sortProperty="Name" sortable="false"

            </tr:column>
          </tr:table>
  

  but the problem is that I don't want radio button for selecting rows.

  If I disassembled rowSelection property box option is hide but not selected table then. and detail table show always record according to the first row of the table.

  Thank you

  Manish

  You don't need to display the key of the fields in the table, but do not add to your links page so that they are accessible - so you can reference them in your link. If you use a composite key, you may need to use the setCurrentRowWithKey instead of KeyValue #{row.rowKeyStr}

  See the section on the setCurrentRowWithKey here: Application Module Databinding tips and Techniques

• I have a problem with c:\users\myname\appdata\local\temp.

  Hello

  c:\users\myname\appdata\local\temp

  I plan to delete ALL/SOME of the files that are in this directory (NOT the files).  One of my applications is broken, and I suspect that it continues in this way due to a forced down while running.

  I read on another thread that is not a good idea to touch the contents of this file, in particular the FOLDERS that are in this folder. Apparently, it causes problems for other applications. http://answers.Microsoft.com/en-us/Windows/Forum/Windows_7-files/deleted-files-in-userappdatalocaltemp-downloads/9dca1f8b-9d37-4a46-a0af-e1fce2662718

  I will only delete FILES after a certain date and WILL NOT affect the files.

  What do you think. This will cause me any grief?

  OK, back again.

  I solved my problem of system by doing a restore of the factory system.

  I got good advice on the above question, and there is no problem with the deletion of everything in this folder. This is something I do on a regular basis as the maintenance of the system.

• Cascading deletion

  I activated on option delete cascade in a single table. What I want is when I delete a row in the AUDIT_PROCESS table, it deletes the row in the FEEDBACK_PROCESS table and the table MICC_AT_ANALISYS. I think I created the constraints on the table to foreign keys feedback_cod and cod_analysis very well audit_process, but when I delete a row in the audit_process table, it doesn't delete the table feeback_process and micc_at_analysis. I don't know if I have to make another step to trigger what I want. Please help me with this.
  
  Here's the code when I created the tables.
  
  I have this table with cascading delete enabled
  

  CREATE TABLE  "AUDIT_PROCESS" 
     (     "AUDIT_COD" NUMBER(5,0), 
       "COD_ANALYSIS" VARCHAR2(5), 
       "FEEDBACK_COD" NUMBER, 
       "AUD_SR" VARCHAR2(15), 
       "AUD_ERROR" VARCHAR2(5), 
       "AUD_OBSERV" VARCHAR2(300), 
       "AUD_OWNER" NUMBER, 
       "AUD_DATE" VARCHAR2(10), 
       "AUD_STATUS" VARCHAR2(5), 
        CONSTRAINT "AUDIT_PROCESS_PK" PRIMARY KEY ("AUDIT_COD") ENABLE
     ) ;ALTER TABLE  "AUDIT_PROCESS" ADD CONSTRAINT "AUDIT_PROCESS_CON" FOREIGN KEY ("COD_ANALYSIS")
         REFERENCES  "MICC_AT_ANALISYS" ("COD_ANALYSIS") ON DELETE CASCADE ENABLE;ALTER TABLE  "AUDIT_PROCESS" ADD CONSTRAINT "AUDIT_PROCESS_CON_FEEDBACK" FOREIGN KEY ("FEEDBACK_COD")
         REFERENCES  "FEEDBACK_PROCESS" ("FEEDBACK_COD") ON DELETE CASCADE ENABLE;

  This table below is one of the parents table

  CREATE TABLE  "FEEDBACK_PROCESS" 
     (     "FEEDBACK_COD" NUMBER, 
       "FEEDBK_AGREE" VARCHAR2(2), 
       "FEEDBK_OBSERV" VARCHAR2(250), 
       "FEEDBK_DATE" VARCHAR2(10), 
       "FEEDBK_STATUS" VARCHAR2(5), 
       "SR" VARCHAR2(15), 
       "ERROR" VARCHAR2(5), 
        CONSTRAINT "FEEDBACK_PROCESS_PK" PRIMARY KEY ("FEEDBACK_COD") ENABLE
     ) ;

  It's the other parent table
  

  CREATE TABLE  "MICC_AT_ANALISYS" 
     (     "COD_ANALYSIS" VARCHAR2(5), 
       "ANALISYS_DATE" VARCHAR2(150), 
       "ANALYSIS_OBS" VARCHAR2(150), 
       "ANALYSIS_STATUS" VARCHAR2(4), 
       "ANALYSIS_SOURCE" VARCHAR2(10), 
       "ANALYSIS_ERROR" VARCHAR2(4), 
        CONSTRAINT "MICC_AT_ANALISYS_PK" PRIMARY KEY ("COD_ANALYSIS") ENABLE
     ) ;

  Bernardo,

  This isn't a typical question of APEX.

  Suggested it was an option.

  CREATE OR REPLACE TRIGGER trg_adr_audit_process
    AFTER DELETE ON audit_process
    FOR EACH ROW
  BEGIN
    DELETE feedback_process WHERE feedback_cod = :old.feedback_cod;
    DELETE micc_at_analisys WHERE cod_analysis = :old.cod_analysis;
  END;
  

  However, if it is in the APEX, you might consider writing a page-process that manages all delete them for you:
  -remove the child
  -remove the parent
  and this process will be triggered by the action of DELETING your page.

  Kind regards

• Problems with the database, on delete cascade

  Hello

  I am in a project with the Flahs CS4 with air and as3. I create a database by code, everything is ok. I have 2 tables,
  a main table with a code field as primary key and other details of the table, named e.g. DetailTable, with 3 fields as the primary key. What I want to do, this is a deletion of a row in MainTable, all lines of DetailTable, where the field code is the same as the field in MainTable code should be deleted also.

  Here's the SQL code to create the tables.

  var sql2:String = "CREATE TABLE If NOT EXISTS MainTable ('+ '.
  "code INTEGER PRIMARY KEY AUTOINCREMENT, ' +.
  "quote," +
  'date ' +.
  "  " +
  ")";

  var sql3:String = "CREATE TABLE If NOT EXISTS DetailTable ('+ '.
  "code INTEGER, INTEGER position, type INTEGER, ' +.
  "path of TEXT, TEXT document, ' +.
  'PRIMARY KEY (code, position, type) +.
  'FOREIGN KEY (code) REFERENCES Detallesecuencia (code) ON DELETE CASCADE ' +.
  ")";

  
  Thus, when the tables are created, insert data. I connect without a problem, remove a line in MainTable (see code), to remove the line with the example code = 4, but in the DetailTable, all with code = 4 lines are NOT deleted, why?

  [CODE]
  Inside of a class

  private var conn: SQLConnection;

  public void constructorClass() {}
  Conn = new SqlConnection ();
  ConexionBD();
  }

  function ConexionBD() {}

  conn.addEventListener (SQLEvent.OPEN, openHandler);
  conn.addEventListener (SQLErrorEvent.ERROR, errorHandler);
  var dbFile:File = File.applicationDirectory.resolvePath ("mydatabase.db");
  conn.openAsync (dbFile, SQLMode.UPDATE);
  }

  function deleteRow() {}
  selectData:SQLStatement = new SQLStatement();
  selectData.sqlConnection = conn;
  selectData.text = "" DELETE FROM MainTable WHERE code =: param1 ";"
  selectData.addEventListener (SQLEvent.RESULT, resultHandler);
  selectData.addEventListener (SQLErrorEvent.ERROR, errorHandler);

  Delete line in MainTable code = 4, but not to delete all the rows in DetailTable with code = 4
  selectData.parameters [": param1"] = 4;
  
  selectData.execute ();
  }
  [/ CODE]

  Thanks in advance

  Hmmm, well then maybe it's you must go down the road of the old school and delete individual tables as needed, rather than rely on the cascade delete.

• Problem of memory in Cascade Delete

  Using JDeveloper and ADF 12.1.2.0.

  I have a master relationship / detail where there may be 200 000 or more details to one master.  In the database, I created the FK constraint with the CASCADE DELETE option.  In the ADF BC file, I put the object of the Association between the two EOs with Composition Association enabled, optimize the Cascade Delete database checked and implement Cascade Delete is automatically checked.

  The cascade delete works fine - when the user deletes a primary record, its details are also deleted.  It works at least as long as the private teacher only has say, 50 000 Details.

  But the more details there are, more memory is used on the server, when a master record is deleted.  With the larger sets of detail (for example, details more than 50,000), this can cause an "out of memory" error, and then the server (WebLogic 12.1.2.0) breaks down.

  I'm not sure I understand why it's behaving as if she brings ALL of the detail records in memory to do the deletion, when the real delete activity should be about the database.  All I can do about it?  Or do we simply give lots of server memory and hope for the best?

  Were not ignoring you - just attend to other priorities.

  I will continue this investigation with some of the suggestions on your part and Timo.

  Meanwhile, our application server administrator discovered that if he gave WebLogic Server 3 GB of memory, we can remove the largest set of detail that we never got into production without crashing the server. So that's what he will give to the production server.  So we have a good workaround solution, and I will mark this as answered.  Thanks for your help.
