use of the table list

Please let me know using the following line:

bufferedlist < q > ArrayList < BufferedImage > = new ArrayList < BufferedImage > (); < /q >

The simpler explanation: an ArrayList is created, which can contain only BufferedImage objects. If you try to save an object that isn't a BufferedImage, the compiler will tell you it's impossible.

  • Help setting up the table/list of choices

    Hello:

    I create an application where I use a custom authentication scheme and captures all user information in a separate table. When the user logs in he will refer to the table to identify a user name and password stored in the table.

    I am allowing users to create their own user accounts that will be default to basic access levels. Further along in the process, users will need to select a person to approve something. I want to use a list of choices so that the name of the approver is entered regularly every time. The user table has the following format:

    Default primary key Type Nullable data column name
    Username VARCHAR2 (8) No - 1
    PASSWORD VARCHAR2 (8) No. -
    FNAME VARCHAR2 (30) - No.
    LNAME VARCHAR2 (30) - No.
    E-MAIL VARCHAR2 (50) - No.
    ADMIN VARCHAR2 (1) Yes.
    APPROVER VARCHAR2 (1) Yes.


    I would like users to be able to choose from a list of choices that displays LNAME, FNAME. I don't know how to make the two fields appear in a list of choices.

    Furthermore, I would like to (if possible) to keep the two separate fields for the creation of user accounts so that I can get a coherent LNAME, FNAME format and people are not go backwards (e.g., Smith, Joe c. Joe Smith).

    If I can't show the two fields in the drop-down list, is there a way where I could add a free calculation filed to the table that will concatenate LNAME"," FNAME?

    Thanks for any help you can provide.

    RKD,

    Create a dynamic list of values.

    select lname||', '||fname displayed, username returned
    from user
    order by 1
    

    You can view what you want, regardless of the value returned. And that includes the concatenation of elements together (or do other calculations/manipulations).

  • Confusion about the use of the tables [was: tables]

    I was told, at some point by someone, that the new web site design uses no tables. I'm so confused that I just read in the Help Guide of Dreamweaver Reference Guide, Chapter 5 page layout and Design, there is a whole section for tables. Many help sites, I was told that my site does not even because it is built in the tables. I built it using the ancient DW in 2002. I don't know which version, but the most recent version was Dreamweaver 4 back then. I am trying the trial of 2015, making many tutorials to learn the latest that has completely changed what I learned 14 years ago.

    So, what I can, or may not, use arrays? Please see the reference guide for DW 2015, 5 ml

    Thank you, Deb

    Oh, my site is mainemadestuff.com

    [Edited by moderator subject line]

    Dreamweaver reference Guide is desperately obsolete. Because Dreamweaver is now updated several times per year, new features have been added, but the old material has not been removed. For example, Chapter 5 contains 12 pages on executives. Dreamweaver can't stand frames.

    Advice than a website "shouldn't even work because it is built in the tables" are nonsense. Your site does not, and will continue to work for many years to come.

    The problem with the page layout using tables, it's that it is rigid. The content is not redistributed when the site is displayed on a mobile device. Tables is also bad for technology assistance for the blind. A blind person trying to access your site would have great difficulty of navigation on every page.

    Tables should be used these days for their original purpose: to display data, such as sports or statistical results in tables of trade. Modern web design uses CSS to control page layout and styles. But do not worry about your existing site stop suddenly work. Spend the time learning the latest techniques and reorganize your site when you feel more comfortable with CSS. But forget the so-called Dreamweaver reference Guide. It will be much more to enlighten confused them.

  • Model for PK not used on the tables of objects

    When uttering a primary key for a table of objects, the model for the primary key name is not used. SDDM (3.1.4 and earlier versions) is the addition of the string 'Oid_' before the name of the primary key table by default. So instead of "TABLE1_PK", the default name is "Oid_TABLE1_PK". It looks like the model is used by the object tables.

  • variable binding can be used for the table in an explicit cursor

    I have an application that accesses a table on several different servers. I created a ref for the slider cursor variable and a varchar2 variable to define my query. variable I_server is a parameter to my procedure. Is it possible to rewrite the v_query using bind variable for the table/Server? I have included below v_query.

    v_query: = "SELECT rp.usr_id, rp.sun_sft_cat, rp.sun_start, rp.sun_hrs," |
    "rp.mon_sft_cat, rp.mon_start, rp.mon_hrs, |
    "rp.tue_sft_cat, rp.tue_start, rp.tue_hrs, |
    "rp.wed_sft_cat, rp.wed_start, rp.wed_hrs, |
    "rp.thu_sft_cat, rp.thu_start, rp.thu_hrs, |
    "rp.fri_sft_cat, rp.fri_start, rp.fri_hrs, |
    "rp.sat_sft_cat, rp.sat_start, rp.sat_hrs, |
    "rp.sun_sft, rp.mon_sft, rp.tue_sft, rp.wed_sft, |
    "rp.thu_sft, rp.fri_sft, rp.sat_sft, nvl (ei.wip_permanent_sched_seq, 0) ' |

    "AND wes.status = rp.wk AND"Y"= 1'; -wk = 1 is the schedule for next week

    Rp_sched_cursor OPEN FOR v_query;

    If your intention is to do this:

    v_query := 'SELECT rp.usr_id, rp.sun_sft_cat, rp.sun_start, rp.sun_hrs,' ||
    ' rp.mon_sft_cat, rp.mon_start, rp.mon_hrs,' ||

    ' rp.thu_sft, rp.fri_sft, rp.sat_sft, nvl(ei.wip_permanent_sched_seq, 0)' ||
    ' FROM ' || :b0 || ' rp, wip_emp_information ei,' ||      --- Note the bindvariable...
    ' wip_emp_status wes, wip_emp_status_type west ' ||
    ' WHERE rp.usr_id = ei.employee_id' ||
    ' AND wes.employee_id = ei.employee_id' ||
    ' AND wes.status_type = west.status_type' ||
    ' AND west.description = ''WAREHOUSE EMPLOYEE''' ||
    ' AND wes.effective_date = (SELECT MAX(wes2.effective_date)' ||
    ' FROM wip_emp_status wes2' ||
    ' WHERE wes2.status_type = wes.status_type' ||
    ' AND wes2.employee_id = wes.employee_id' ||
    ' AND wes2.effective_date <= trunc(SYSDATE))' ||
    ' AND wes.status = ''Y'' AND rp.wk = 1'; -- wk = 1 is next week's schedule
    
    OPEN rp_sched_cursor FOR v_query USING i_server;
    

    So the answer is: no, you can do that.

    But then, my question would be: why would you do that?
    I guess that you have many "different servers. A cursor on the server will not hurt you.

  • Name of the table list ALL_TABLES but not in TABS

    Hello

    I was trying to programatically check if a table is exist or not and insert the records if exist (via Java). I see a weired behaviour where when I check the metadata through my connection, I see this table_name in it (don't think there is an error in the logic), but when I try to insert a record after that, he lifts - java.sql.SQLException: ORA-00942: table or view does not exist.

    When I manually check the DB, I see this table to table ALL_TABLES but not in TABS (not sure what is the same difference between those two, and that is the right place to check), desc < table_name > is also a failure...

    I'm really confused if the table is exist or not...

    Any help is really appreciated.

    Hello

    Does it that way if you want to use the alias with the County, you must do the following:

    BindingContext bctx = BindingContext.getCurrent ();
    BindingContainer links = bctx.getCurrentBindingEntry ();
    AttributeBinding salaryBinding = bindings.get ("Salary") (AttributeBinding);
    Oracle.jbo.domain.Number salaryValue = (Oracle.jbo.domain.Number) salaryBinding. getInputValue();.
