Count the number of rows resulting from a select statement

Hi,
Is there any way of counting the number of rows resulting from a select statement. i.e I have a select distinct statement and I then want to perform an IF statement on the number of rows resulting from the select statement.
Any help appreciated
Thanks
Gary

Declare
var1 number;
Begin
select count(distinct column_name) into
var1 from table_name;
If var1 > x Then
End IF;
End;
Hope I understood the problem correctly

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

    : 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

  • Can I limit the number of rows returned on a Select?

    Can I limit the number of rows returned on a Select statement? I would be using JDBC in a Java program.

    Use Java prepared statements with the equivalent of this SQL*plus script:
    VARIABLE n number
    EXEC :n := 3;
    SELECT rownum FROM all_objects WHERE rownum <= :n;
        ROWNUM
             1
             2
             3
    EXEC :n := 5;
    SELECT rownum FROM all_objects WHERE rownum <= :n;
        ROWNUM
             1

  • How to count the number of rows in a resultser object?

    hi there
    how to count the number of rows in a resultser object which may contains millions of rows? besides using a while loop? thanks

    You don't, you execute a query whose result is the record count of those records that match the search and then you execute the actual query to create your record set. Typically you do
    select count(id) from YourTable where [filter]
    from the resulting ResultSet do
    int res.getInt(1);
    which gives you the count and then
    select id from YourTable where [filter]
    to produce the actual result set.
    in the second query the id part can be substituted with the actual fields you want.

  • How to count the number of Rows to be Updated before Update takes place..

    Hi all,
    I have a requirement, where i have to count the number of rows to be updated before updating it. SQL%ROWCOUNT gives the no. of rows updated ( after update takes place). How do i get to know the count of no. of rows to be updated/inserted/ deleted. I was looking for a simple solution, as above SQL%Rowcount. But i couldn't find any. I can use a Function and Return the value which will give me number of rows to be updated, But is there any Simple Logic other than this.. or any count function. Your Help is Appreciated. Thanks!

    If you really want to do this (I have no clue why you would need it), then you can piggy back on any existing pessimistic locking you may already have in place.
    However, it would require two loops through the records of which you want to know the count before you update, and a second pass to update them.
    I would really re-think the need for this, though.

  • Count the Number of Rows in Data form

    Hi,
    I want to count the number of rows in a data form.In my form there is a large number of rows.Is there any way to count it.
    Thanks.

    If you are on 11.1.2.x then you could look at adding a formula and using the CountA function - http://download.oracle.com/docs/cd/E17236_01/epm.1112/hp_admin/apcs03s06.html
    Otherwise it would be possible using custom javascript which you would have to had some experience in using.

  • Count the number of rows in a workbook.

    Hi Experts , I have a requirement to count the number of rows in a WorkBook.Will it be possible to do this by creating a KeyFigure?Or are there any options in BEx to count and display the number of Rows.Many thanks for all your help.

    Hi
    In the query create a calculated key figure called 'Count' and put a formula as =1, then use this count where ever applicable..you can very well count the no. of rec.
    with this.
    Hope this helps..
    assign points if useful..

  • How do you limit the number of rows return from query?

    How do you limit the number of rows return from query? Do all databases support this kind of feature?

    i think the standard is limit
    to get the top 30
    select * from mytable LIMIT 30;returns the first 30 rows
    also if you want a range
    select * from mytable LIMIT 10,30;returns 30 rows starting from 10
    this last one is useful for displaying ranges... something similar happens in these forums when viewing topics and messages

  • Can I "count" the number of rows excluding the header and footers

    I have some tables that consist of a different number of rows, as the number is part of an equation I need to know the number of rows excluding the header and footers. I have the work around in =ROWS(ColumnG)-3, but is there a tidier way? I want to be able to add footers (or headers) too and not have these counted.
    Many thanks
    Lee

    Hi Lee,
    Add a column to your table (for purposes of this discussion, the new column is placed before column C, and becomes the new column C). enter the formula below in all regular cells, but NOT in header or footer cells:
    =1
    Use the formula below, placed anywhere (except in a regular cell in column C) to get the number of non-header, non-footer cells:
    =COUNT($C)
    The first formula will automatically be placed in cells added to column C, and the results will change to reflect the added rows.
    Regards,
    Barry

  • Count the number of rows in an array

    Hi there,
    I'm quite new with Labview, maybe somebody can help me.
    I have a .vi that controls two pump with certain ratios (to make a composition gradient). I export the data to an ascii file, which write the displacement of the two pumps in 2 colums. However, the number of rows is related to the ms-counter, and thus related to the processor of the computer. Now I need, at the end of the vi, to get the number of rows written to the ascii file, to do some further calculations. Does anybody know how to do this?!
    Thanks

    You could wire the loop-counter to a variable outside the loop, so you can see the number of iterations (don't forget to add 1).
    You also can use the Array Size-Function. Here you get different outputs, according to the dimensions of the array to get the size of.
    Here you can see what you get if you use this function:
    1D-Array: one value
    2D-Array: array, item 0 = number of rows, item 1 = number of columns
    3D-Array: array, item 0 = number of pages, item 1 = number of rows, item 2 = number of columns
    So if (in your case) you wire a 2D-Array you can use the array-size function, select item 0 of the array you get and you get the number of rows.
    You can also have a look at the attachement.
    Hope it helps.

  • Getting the number of rows returned from ResultSet

    Hi,
    Does anyone know a method to get the number of rows returned with a query using the Resultset class?
    Thanks.

    Hi 281080,
    If your database and JDBC driver support it, in order to use the solution that da-alexj has suggested, you need to create a 'scrollable' "ResultSet" -- the javadoc for method "createStatement()" (in class "java.sql.Connection") has more details.
    However, I have found with Oracle 8.1.7.4 database and Oracle (thin) JDBC driver, that part of their implementation of the "last()" method (in class "java.sql.ResultSet") is to actually iterate through the entire "ResultSet" in order to reach the last row. If your "ResultSet" is very large (I tested it with a 100,000 row "ResultSet"), this will take a long time.
    Just wanted to make you aware of that.
    Of-course, this may be irrelevant to you since I didn't see any mention in your post of what database and JDBC driver you are using.
    Hope this has helped you, anyway.
    Good Luck,
    Avi.
