try to catch the declaration?

What is the meaning of the following code?

Try (statement1;

statement2 ;) {

statement3;

statement3;

}

(} catch Exception e) {}

Statement of exception;

}

I know that the statement try-catch as follows:

try {}

statement1;

} catch (Exception e) {}

exception_statement;

}

Things have changed since the last time I looked. But why the first part of the code has been put in place?

You can instantiate resources that implement the interface that can close and the compiler add code to close when the try block terminates.

FIR example that comes to mind is this typical JDBC management:

//old code:
Statement stmt;
ResultSet rs;
try {
  Statement stmt=connection.createStatement();
  ResultSet rs = methodThatExcecutesJdbcStatemendCatchingTheJdbcExceptionOnItsOwn(stmt)
  List dtoList = new ArrayList<>();
  while(rs.next())
    dtoList.add(  new Dto(rs.getBigInteger(1),rs.getString(2)));
}(catch JdbcException ex){
  throw new RuntimeExceotion(ex.getMessage());
} finally{
  if(null!= rs) { try{ rs.close()}(catch JdbcException ex){throw new RuntimeExceotion(ex.getMessage());}}
  if(null!= stmt) { try{ stmt.close()}(catch JdbcException ex){throw new RuntimeExceotion(ex.getMessage());}}
}

// new code
try( Statement stmt=connection.createStatement(); ResultSet rs = methodThatExcecutesJdbcStatemendCatchingTheJdbcExceptionOnItsOwn(stmt)){
List dtoList = new ArrayList<>();
  while(rs.next())
    dtoList.add(  new Dto(rs.getBigInteger(1),rs.getString(2)));
}(catch JdbcException ex){
  throw new RuntimeException(ex.getMessage());
}

you see the difference?

Good bye

    Hello

    It's strange, maybe you can try to use the timestamp type rather type date and with the help of an offset in the case where the work already finished for example d = systimestamp - second interval '1'

    Another thing to watch is if you compare the dates in the same time zone, otherwise you must ensure that all sessions use the same time zone (setting the default_timezone attribute Planner can help).

    Hope this helps,

  • How to set a partialTriggers for the declarative component

    12.1.3 jdev

    I try to set partialTriggers for my component declarative.

    From another forum, people suggested using one different name other than partialTriggers to avoid override a final method in RichDeclarativeComponent.

    Then, I set this:

    < afc:attribute >

    < afc:attribute - name > myPartialTriggers < / afc:attribute - name >

    < afc:attribute - class > java.lang.String [] < / afc:attribute - class >

    < / afc:attribute >

    and

    "< af:selectOneChoice id = simple =" #{attrs.simple "dc_droplist_soc"} "readOnly =" #{attrs.readOnly} "disabled =" #{attrs.disabled} ' "

    value = "#{uploading." "Value}" label = "#{attrs.label}" binding = "#{dropListComp.selectOneChoice}".

    "autoSubmit =" #{attrs.autoSubmit} "required =" #{attrs.required} "visible =" #{attrs.visible} ' "

    valueChangeListener = "#{dropListComp.handleValueChangeListener} '"

    partialTriggers = "#{attrs.myPartialTriggers} ' / >"

    But it does not work. I don't see a partialTriggers work.

    Any suggestions?

    Thank you.

  • How to conditionally bind the declarative component custom ADF ADF Faces

    Hi gurus,

    I created the custom declarative component called "Historical Record", following the article of Frank Nimphus Oracle ADF Code corner: How to bind custom declarative ADF Faces components and it works perfectly find.

    But I want to strengthen further to make more generic, as in Oracle EBS we can go to all the blocks and choose Tools-> history of the record and it shows WHO columns to the currently selected record.

    The intention is conditionally bind the attributes of the component with columns of WHO bodies VO.

    The scenario is:

    * all tables have Created_Date, Modified_Date for columns of the WHO.

    * the page containing the 2 instances of VO with different source (for example:-> emp dept)

    * whenever I have navigate dept records it should display columns WHO selected dept and the same thing then to move through the records of the emp.

    Kind regards

    Well as I said, you shouldn't try to rebuild the Oracle Forms technology-specific behavior in some other technologies such as ADF (because it is not usually possible).

    It is probably best to have a separate button for each shape (square to a coherent position on all pages - as some form, toolbar header...)

    If you want to rebuild the behavior of forms, then you can use the combination of af: clientListener / af:serverListener to set a flag (as the name iterator) see scope that can be used by your 'global' button to retrieve the correct data. Therefore, add af:clientListener to each component entry...

  • Try to handle the exception of another block, do not get it... Precious need help please...

    Hi, fields,

    I want to RAISE an exception through my first procedure and want to manage it in the second procedure. [I think it's concept of reproduction or multiplication exception].

    Not able to do, need your valuable advice.


    create or replace procedure test_excep1 (a number, b number)
    is
    c number;
    external_exception exception;
    Start
    c: = a / b;
    dbms_output.put_line ('Came out' | c);
    exception
    When zero_divide then
    raise external_exception;
    end;

    Start
    test_excep (2,0);
    end;

    When executing procedure above with divisor of zero, I get the error message below

    ORA-06510: PL/SQL: not supported by the user-defined exception
    ORA-06512: at "SONARDBO. TEST_EXCEP', line 10
    ORA-01476: divisor is equal to zero
    ORA-06512: at line 2


    Now if I try to catch this exception by another procedure, it does not help me. -This is my exact requirement.


    Create procedure test_excep2 (in numbers, number e d)

    When running over block, get the message below.

    ORA-06512: at line 2

    Thanks a ton in advance for help.

    Everything simply because you called an undefined exception 'external_exception' in a unit of code, and then reuse the name in another--does not mean that the variables of these exceptions are for the same exception. Common names mean nothing in this case. Using the same name for the variables or constants and exceptions across modules/units of code, does not mean that they are now the same.

  • help to try to simplify the form table, based on the collection using dynamic measurements

    Hi everyone, I have tried cleaning and simplify an application designed in 2008 apex 3.2.  We have improved in 4.1.2 and want to take advantage of our understanding of the apex and the dynamic measures to simplify a large part of our code, get rid of the redundancies and make it easier for the programmer to debug and improve next.

    The application is for traders and commercial fishermen and currently has around 4100 users.

    The part that I'm trying to simplify is a tabular report, based on a collection.  Almost all areas in this tabular form has a logic linked to it... and in most cases, it is superfluous in that it executes a UPDATE_MEMBER on the collection.  I would like to remove as much of javascript and additional processes as possible.   I'm also still very new to jQuery and javascript, and faced with the two... but competent in pl/sql.

    tabular query is:

    {code}

    I am slow at first and just try to replace the ONCHANGE for apex_item 41 (retail price).   I hope that finally replace all the onblur/onchange to use the same dynamic action.

    The ONCHANGE for apex_item 41 is currently:

    {code}

    function setSalePrice (pRow, savePrice)

    {

    get var = new htmldb_Get (null, & APP_ID., 'APPLICATION_PROCESS is saveSalePrice', 0);

    Get.Add ('SETVALUE3', savePrice);

    Get.Add('ATTRNBR3','41');

    Get.Add ('SEQUENCEID', Prow);

    gResult = get.get ();

    }

    {code}

    the saveSalePrice application process is:

    {code}

    Start

    apex_collection.update_member_attribute (p_collection_name = > 'SPECIES_COLLECTION',)

    p_seq = >: SEQUENCEID.

    p_attr_number = >: ATTRNBR3,.

    p_attr_value = >: SETVALUE3);

    end;

    {code}

    I created two new hidden fields: P110_ID and P110_VALUE.

    I created a dynamic action: CHANGE COLUMN

    event: change

    selection type: jQuery Selector

    jQuery Selector: input [name = "f41"]

    real action 1 - records P110_ID with javascript expression: this.triggeringElement.id

    real action 2 - P110_VALUE value with javascript expression: this.triggeringElement.value

    true action 3 - run pl/sql code

    {code}

    declare

    number of v_member;
    number of v_seq;

    Start
    v_member: = TO_NUMBER (SUBSTR (: p110_id, 2, 2));
    Select ltrim (substr(:p110_ID,5,4),'0 ') in the double v_seq;

    safis_collections.update_column (v_seq,
    v_member,
    (: p110_value);
    end;

    {code}, where safis_collections.update_column is a package of db

    {code}

    Procedure update_column ()v_seq in varchar2

                            v_attr in number ,

                            v_value in VARCHAR2 )

    is

    Start

    apex_collection . update_member_attribute()p_collection_name=> 'SPECIES_COLLECTION'

                         p_seq = > v_seq ,

    p_attr_number = > v_attr ,

    p_attr_value = > v_value );

    apex_debug . message ()'put a day of column.seq ='| v_seq || 'attribute =' || v_attr || "with" || v_value );

    end ;

    {code}

    real action 4 - refreshment area

    I modified the query in a table to reference apex_item 41 to be

    Decode(C020,'Y',apex_item.) Text (41, TO_NUMBER (c041), 5, null), 'No,' N/a ') Sale_Price in the hope that it would fire the dynamic action.   I get the below error.  The value of P110_ID is null, the value of P110_VALUE seems to be correctly set.

    call returned Ajax Server ora error-sequence of 20103:member does not work
    There are in the collection 'SPECIES_COLLECTIO' application to run PL/SQL code

    I appreciate all thoughts/help on this.

    Thank you, Karen

    AHHA.  change the query to

    Decode (c050, 'Y', apex_item.textarea (28, c028, 3, null, null,,'f28_'| seq_id, cm), ' n ',' n/d "") explanation,.

    and that did the trick.  On the next item.

Can someone tell me please a tutorial or an example that works in the way to read a collection by using the checkboxes and manipulate? Normally, I uses a FRONT of Validations process to update the collection with the changes that the user has provided, then follow up with any validations, then run any what DB written/modifications/deletions in a page AFTER VALIDATION process.

    Here's what I have so far:

    Area to the left (list of items already included in the package)

    If anyone has a better way of doing things, I'm ready for it. The standard tabular forms appear not to be the right thing, because there will be TWO shapes on the page, that's why I went with a collection.

    Hello

    I just have a quick look and see what you're trying to do.

    One thing, you might want to consider, is that you use to identify each item (those who become G_F01, G_F02 etc.), index numbers can be any number you like up to a maximum of 50. So, your region on the left could use numbers from 1 to 25 and those rights could use 26 to 50 - little matter if there are gaps in the numbers.

    I'm actually about to close for the day because he went from 19:00 here now, so can't not consider this news right now - but if the above does not do, just update the thread and I'll have another look tomorrow.

  • DBAdapter: Impossible to catch "the database host is down" scenario as a flaw

    Hello

    I use a DBAdapter and try to test the scenario when the database is out of service.

    I have attached a tote within reach with the "systematically" to the DBAdapter and since he did not work an explicit fault Manager Catch so trying to catch a "remoteFault" with the data from the fault to be captured in a variable 'RuntimeFault' to type 'RuntimeFaultMessage '.

    The problem is that my fault handlers intercept not defects, and I get an errors of ORABPEL-11622/08033/05002 as pasted below:

    -----

    To simulate that my database is down, my DBAdapter wsdl I put my < jca:address > section as:
    -----
    < jca:address location = ' ist/DB/Unknown"UIConnectionName ="BPEL_DB_Server ".
    ManagedConnectionFactory = "oracle.tip.adapter.db.DBManagedConnectionFactory"
    MCF. DriverClassName = "oracle.jdbc.OracleDriver"
    MCF. PlatformClassName = "oracle.toplink.internal.databaseaccess.Oracle9Platform"
    MCF. ConnectionString="jdbc:oracle:thin:@172.16.205.120:1522:ETGLIT".
    MCF. UserName = "owf_mgr_temp".
    MCF. Password = "867BD34C5AE6EF60BEC0F888655A72920D60DCB1D74A4B78" / >
    -----

    Since then, there is no location "eis/DB/Unknown" Bpel would use other attributes defined here to connect to the database. But the IP database I specified here is incorrect to make sure that DBAdapter fails to connect.

    Now, I received the error "Network adapter could not establish the connection" but it appears in my logs to opmn with the above pasted stack trace. Why am I unable to catch this problem of connectivity as a bpelx:remoteFault in my capture explicit or CatchAll?

    Help, please!

    Kind regards
    Ravi

    I am surprised as well. I see you're on 10.1.3.1. There are a lot of problems with the DB adapter in this version. I suggest either install the following hotfixes or upgrade to 10.1.3.3 or 10.1.3.4 (recommended)

    What happens to the BPEL process, do go to manual recovery? Or just fail. Are you sure that the Tote was beyond the scope of the DB adapter. Have you implemented several scopes?

    see you soon
    James

  • Error when try to use the rowid with the table alias

    I tried using a table alias to test the functions of Manager of rules and met the following problems.

    1. I have clone from a schema HR employees and departments tables.

    2. create data as follows:

    BEGIN
    dbms_rlmgr.create_event_struct (data = > 't_a');
    dbms_rlmgr.add_elementary_attribute (data = > 't_a',)
    attr_name = > "a_employees"
    tab_alias = > exf$ table_alias ('employees'));
    dbms_rlmgr.add_elementary_attribute (data = > 't_a',)
    attr_name = > "a_departments"
    tab_alias = > exf$ table_alias ('departments'));
    END;

    3. create the class rule as follows:

    BEGIN
    dbms_rlmgr.create_rule_class (rule_class = > 't_as',)
    Event_Struct = > 't_a. "
    action_cbk = > 't_acb ',.
    rslt_viewnm = > 't_arv');
    END;

    4. After adding a rule to the rule class, I try to test as follows

    DECLARE
    r_emp ROWID.
    r_dept ROWID.
    CURSOR a_cur IS
    SELECT emp. ROWID, Dept. ROWID
    Employees OF ministries dept (IEM),
    WHERE emp.department_id = dept.department_id;
    I have NUMBER: = 1;
    BEGIN
    OPEN a_cur;
    LOOP
    EXTRACTION a_cur
    IN r_emp, r_dept;
    EXIT WHEN a_cur % NOTFOUND;
    dbms_output.put_line (i);
    i: = i + 1;
    dbms_output.put_line (r_emp);
    dbms_rlmgr.add_event (rule_class = > 't_alia',)
    event_inst = > r_emp,
    event_type = > 'employees');
    dbms_rlmgr.add_event (rule_class = > 't_alia',)
    event_inst = > r_dept,
    event_type = > "departments");
    END LOOP;
    END;

    But I got the following error

    SQL > DECLARE
    2 r_emp ROWID.
    3 r_dept ROWID.
    4 a_cur CURSOR IS
    5. SELECT emp. ROWID, Dept. ROWID

    7 WHERE emp.department_id = dept.department_id;
    8 I COMP: = 1;
    BEGIN 9
    10 a_cur OPEN;
    11 LOOP
    12 FETCH a_cur
    13. IN r_emp, r_dept;
    EXIT 14 WHEN a_cur % NOTFOUND;
    15 dbms_output.put_line (i);
    16 I: = i + 1;
    17 dbms_output.put_line (r_emp);
    18 dbms_rlmgr.add_event (rule_class = > 't_alia',)
    19 event_inst = > r_emp,
    20 event_type = > 'employees');
    21 dbms_rlmgr.add_event (rule_class = > 't_alia',)
    22 event_inst = > r_dept,
    23 event_type = > "departments");
    24 END LOOP;

    Hello

    ROWID for individual tables can be added as events only if the rule class is set up as a Composite. For all other cases, ROWID is treated as data and they need to be formatted as a string of instances of AnyData or name-value pairs. Your script is to think that you intend to create a composite rule class while you might add ROWID individually. If please, recreate the rule as a composite class and try again. The error message you received is incorrect and has been corrected to indicate that the error is with the format data point past.

    Hope this helps,
    -Aravind.

  • I called Amazon to try to recover the serial number of my old iPod classic two weeks ago, and they gave me a kind of account; They pronounce it account 'seen - It '.

    I called Amazon to try to recover the serial number of my old iPod classic two weeks ago, and they gave me a kind of account; They pronounce it account 'seen - It '. I don't have to ask how, because I thought I knew, but I was wrong. Would what type of account be? And how it's spelled? The name of the account is a tiny s followed a 7-digit number. (Of course I will not type the numbers.)

    I would go to a forum for Amazon, because they can be better equipped to answer a question on their system. If synchronize you the device with iTunes, the number can be there in the backup section.  Find the serial number of your Apple - Apple Support product

    Hello monorayfromportland,

    If you are unable to connect to the iTunes Store on your Apple TV, take a look at the troubleshooting steps below:

    If you cannot connect to the iTunes Store

    If you cannot connect to the iTunes Store on your Apple TV (4th generation):

    1. Make sure that your date and time are correct. Go to settings > general > Date and time.
    2. Check if your Apple TV software is up-to-date. To check the updates, select settings > system > software updates > software update.
    3. Make sure you have an active network connection. Go to settings > network.
    4. Check to see if other devices, such as computers or tablets, can connect to Wi - Fi and access to the Internet.
    5. Reset the wireless router by turning and then again.

    Take care.

    There is no sound when I try to play the songs in my library or radio.  The speakers are very well because I can play from iTunes radio on the internet and local music. I've deleted and reinstalled iTunes, restarted my computer and I know that the sound is turned on. Curiously, it seems that the song moving forward and does not in fact (the blue line streaming lights up blue when I select a song or an advance to the next song.
