How can i limit my rows in a query?

What SQL query could i use to limit rows for example from 5 to 5 rows?
for example:
Select EmpNo, Ename From Emp; (imagine it has 10,000 records) and i want to present them as 5 at the same time.
what SQL query or instruction should i use? (since CURSORS are not an SQL standard) how else could i achieve that?
thanks

  • How can I limit the number of rows returned by a select stat

    How can I limit the number of rows returned by a select
    statement. I have a query where I return the number of stores
    that are located in a given area.. I only want to return the
    first twenty-five stores. In some instances there may be over
    200 stores in a given location.
    I know is SQL 7 that I can set the pagesize to be 25....
    Anything similiar in Oracle 8i?

    : If you are in Sql*Plus, you could add the statement
    : WHERE rownum <= 25
    : Used together with an appropriate ORDER BY you
    : could get the first 25 stores.
    Watch out. ROWNUM is run before ORDER BY so this would only
    order the 25 selected

  • How can I limit the number of ros in TextArea?

    As I turn on the line wrap and having used setRows method,
    I cannot limit the number of rows of the textarea into 2.
    How can I limit it?
    Thanks.

    due to setText method So this implies that the text comes from somewhere, maybe a database, but the user does not type the text directly into the text area.
    If you define the text area with 2 rows, then the third row will not be visible, so I don't see the problem. Just don't add the text area to a scroll pane and the user will never know the third row is there.[http://i188.photobucket.com/albums/z55/nwoedf/temp/error.png ]
    it demonstrates the problem with excess line
    The third row is still visible even I have used setRow(2).

  • How can I limit the number of emails retained on my ipad air?

    How can I limit the number of emails that are retained on my iPad Air?  Because of legal requirements of a long-term project, I cannot permanently delete emails relating to that project from my ISP's mail server.  My gmail account contains over 17,000 emails and, upon setting up my new iPad, and updating to ios 7.1.1, I now have all 17,000+ emails taking up space.  I would like to limit the emails by count as I was able to do on my old iPad running ios 5.1.1 OR to retain them based on date range.  I have not found any instructions on the support discussions or general iPad blogs that allow me to do that.  Any way around this problem?
    I also miss the 5.1.1 mail search feature that allowed me to narrow the search by from/to/subject/all.  Does anyone know if that feature is available using some little-known ios 7.1.1 feature?
    Thanks for your help.

    If you have a decent mail provider like Microsoft Hotmail or Outlook.com mail it does.
    If you have Gmail it does not.  Quite right. Gmail is rubbish.

  • How can I use multiple row insert or update into DB in JSP?

    Hi all,
    pls help for my question.
    "How can I use multiple rows insert or update into DB in JSP?"
    I mean I will insert or update the multiple records like grid component. All the data I enter will go into the DB.
    With thanks,

    That isn't true. Different SQL databases have
    different capabilities and use different syntax, That's true - every database has its own quirks and extensions. No disagreement there. But they all follow ANSI SQL for CRUD operations. Since the OP said they wanted to do INSERTs and UPDATEs in batches, I assumed that ANSI SQL was sufficient.
    I'd argue that it's best to use ANSI SQL as much as possible, especially if you want your JDBC code to be portable between databases.
    and there are also a lot of different ways of talking to
    SQL databases that are possible in JSP, from using
    plain old java.sql.* in scriptlets to using the
    jstlsql taglib. I've done maintenance on both, and
    they are as different as night and day.Right, because you don't maintain JSP and Java classes the same way. No news there. Both java.sql and JSTL sql taglib are both based on SQL and JDBC. Same difference, except that one uses tags and the other doesn't. Both are Java JDBC code in the end.
    Well, sure. As long as you only want to update rows
    with the same value in column 2. I had the impression
    he wanted to update a whole table. If he only meant
    update all rows with the same value in a given column
    with the same value, that's trivial. All updates do
    that. But as far as I know there's know way to update
    more than one row where the values are different.I used this as an example to demonstrate that it's possible to UPDATE more than one row at a time. If I have 1,000 rows, and each one is a separate UPDATE statement that's unique from all the others, I guess I'd have to write 1,000 UPDATE statements. It's possible to have them all either succeed or fail as a single unit of work. I'm pointing out transaction, because they weren't coming up in the discussion.
    Unless you're using MySQL, for instance. I only have
    experience with MySQL and M$ SQL Server, so I don't
    know what PostgreSQL, Oracle, Sybase, DB2 and all the
    rest are capable of, but I know for sure that MySQL
    can insert multiple rows while SQL Server can't (or at
    least I've never seen the syntax for doing it if it
    does).Right, but this syntax seems to be specific to MySQL The moment you use it, you're locked into MySQL. There are other ways to accomplish the same thing with ANSI SQL.
    Don't assume that all SQL databases are the same.
    They're not, and it can really screw you up badly if
    you assume you can deploy a project you've developed
    with one database in an environment where you have to
    use a different one. Even different versions of the
    same database can have huge differences. I recommend
    you get a copy of the O'Reilly book, SQL in a
    Nutshell. It covers the most common DBMSes and does a
    good job of pointing out the differences.Yes, I understand that.
    It's funny that you're telling me not to assume that all SQL databases are the same. You're the one who's proposing that the OP use a MySQL-specific extension.
    I haven't looked at the MySQL docs to find out how the syntax you're suggesting works. What if one value set INSERT succeeds and the next one fails? Does MySQL roll back the successful INSERT? Is the unit of work under the JDBC driver's control with autoCommit?
    The OP is free to follow your suggestion. I'm pointing out that there are transactions for units of work and ANSI SQL ways to accomplish the same thing.

  • HT2729 I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

    I have limited space on my new ipad. How can I limit the number of songs from my itunes on my imac from going to my ipad when I connect the two?

    you can do this by keeping the external hard drive connected and doing the following
    -hold shift key down on computer while opening iTunes and a prompt will appear to choose a library
    -select choose library, iTunes should bring up your explorer windows where you can search for the external HD
    -after you find the external HD find the iTunes folder you just copied to it
    -after opening the iTunes folder look for the file that says iTunes library.itl or if you can't see that extenstion just look for a document looking thing in the iTunes folder that shows up as a database file
    -double click the database file and boom iTunes should load your library without having to copy it to the computer
    PS: do make sure that if you are going to do it this way, make sure that the external HD is connected at all times, because if you don't then you will get exclamation marks next to your iTunes songs
    double PS: if you are unsure how to find out if the iTunes library file is a database file just right click it and choose properties and under the type it should say database file
    hope this helps:)

  • Hi, how can I limit the number of emails I can see on my iPhone 5. Every time in delete one and older email gets added from my live.co.uk account (where I want to keep my 2500 emails) I just don't want many on my phone. Thanks

    You can't. Why on earth would you attempt to manage 2500 emails with setting up a folder structure or some means of doing so? Simply keeping them in an single inbox is not realistic, no matter what email client you use.

    Thanks

    No my question is how can I add and remove rows WITH buttons My point was the code is the same. You use the addRow(...) method. Why did you write an addRow(...) method if you aren't going to use it?
    I don't understand your problem. Do you not know how to write an ActionListener?

    How can I limit numeric codes in a text field? For example I want to list Industry SIC codes and I want to block someone from inputting an exlcuded industry code.

    We don't offer that type of input restriction for a text field. 
    Can you create a list of all allowed codes and use a Drop Down menu or Single/multiple Choice field?

    You can set the pref <b>browser.urlbar.formatting.enabled</b> to <i>false</i> on the <b>about:config</b> page.
    To open the <i>about:config</i> page, type <b>about:config</b> in the location (address) bar and press the "<i>Enter</i>" key, just like you type the url of a website to open a website.<br />
    If you see a warning then you can confirm that you want to access that page.<br />
    *Use the Filter bar at to top of the about:config page to locate a preference more easily.
    *Preferences that have been modified show as bold(user set).
    *Preferences can be reset to the default or changed via the right-click context menu.

    Yoel -
    We're talking about end users of applications you develop in Application Express, not users that login to the development environment.
    You do not have to use Application Express to create user accounts for your application. Your apps can authenticate using SSO, LDAP, or other methods. If you use Application Express user accounts, that is only for convenience which may not be convenient in the long run if you have to manage those accounts, but that's up to you.
    These Application Express accounts have no relation to database accounts. This situation is slightly different when using the XE database.
    Your application's authorization logic determines which users can access the application, pages, or other components, that is, it is not the user account properties, per se, that control application access but rather the application's determination about the properties of the authenticated account in use that allow it to control access. For example, you don't create an account and give it attributes that say this user can access application ABC and pages 1,2, and 7. Instead, you might give that account properties like SALES MANAGER ROLE and the the application would allow only users with SALES MANAGER ROLE (whatever that means) to access certain pages.

  • How can I add new row/column into existing jTable?

    Hi add!
    Can you help me how can I add new row/column into existing jTable?
    Tnx in adv!

    e.g
    Create two buttons inside the Table ( "Add New Row" ) and ("Add new Column")
    their handlers are:
    add new row:
    //i supose u already have
    DefaultTabelModel tablemodel = new DefaultTableModel(rowdata, columnNames);
    //and   
       JTabel jtable = new JTable(tablemodel);
    // Handler (row)
    jbtAddRow.addActionListener(new ActionListener(){
       public void actionPerformed(ActionEvent e) {
          if(jtable.getSelectedRow() >= 0 )
              tablemodel.insertRow(jtable.getSelectedRow(), new java.util.Vector());  
           else  
                tablemodel.addRow(new java.util.Vector());
        });to add new columns its the same but inside actionPerformed method:
    ask for e.g "Whats the name for the new column"
    then,
       tablemodel.addColumn(nameOfColumn, new java.util.Vector());   Joao
