  • To get the count of records and able to access the column value in a single

    Hi
    Is there any way to get the number of records in the query and access the column values
    e.g
    select count(*)
    from
    (SELECT department, COUNT(*) as "Number of employees"
    FROM employees
    WHERE salary > 25000
    GROUP BY department ) a
    This wil only get the Count, if i want to access each row from the inline view how can i do that.

    Your question is not clear.
    Are you looking for total record count as well as count by department ?
    Something like this?

  • Need to get the count based on the column availability

    You get a set of table names from a query, say
    select table_name from all_tab_columns where column_name like 'DC_I’;
    TABLE_NAME
    A
    B
    C
    Now, for the above set of tables (A,B and C), you need to get the count(*) for a single dc_i value (say XXX DC)
    In simple words, its like framing the following 4 separate queries into one single one:
    select table_name from all_tab_columns where column_name like 'DC_I’; (Based on this o/p, following 3 queries..)
    select count(*) from A where dc_i=XXX;
    select count(*) from B where dc_i=XXX;
    select count(*) from C where dc_i=XXX;
    Thanks

  • How to get the count of each minutes

    Oracle 10 DB
    Hi All
    I using this query to get the count of records fetched by the concurrent program per min,
    select count (distinct b.attribute2)
    from oe_order_headers_all a,oe_order_lines_all b
    where a.header_id=b.header_id
    and b.flow_status_code ='AWAIT_QUINTIQ_BOOK'
    and to_Char(b.last_update_date,'DD-MON-YYYY HH24:MI:SS') between '19-JAN-2011 02:00:01' AND
    '19-JAN-2011 02:00:02'
    This is used to get the count of records fetched at one mins
    How to find the count of last 10 mins ie 1 mins count 2.00 to 2.10
    Thanks & Regards
    Srikkanth.M

    Try this:
    SELECT TRUNC(b.last_update_date, 'mi') time_mins, COUNT(DISTINCT b.attribute2)
    FROM   oe_order_headers_all a,
           oe_order_lines_all b
    WHERE  a.header_id = b.header_id
    AND    b.flow_status_code = 'AWAIT_QUINTIQ_BOOK'
    AND    b.last_update_date >= to_date('19/01/2011 02:00:00', 'dd/mm/yyyy hh24:mi:ss')
    AND    b.last_update_date < to_date('19/01/2011 02:10:00', 'dd/mm/yyyy hh24:mi:ss')
    GROUP BY TRUNC(b.last_update_date, 'mi');I'm not sure why you're bothering with the join to the oe_order_headers_all table, since you're not referencing that in the where clause or the selected columns list. I think you could probably do away with it.
    I've changed your code to take the last_update_date and truncate it to the minute level, and added that as a column, so you can see which count goes with which minute. Obviously, this has to be in the group by.
    I've also changed your date comparisons so that you're actually comparing dates to dates, rather than strings to strings - why would you deliberately take information away from the optimizer? Oracle does not treat strings the same as dates, and forcing it to use strings rather than dates could lead you to have a vastly differing execution path, which will most likely be less performant.
    Not to mention, coding like that leads you to assume that you can compare dates in strings without any problems, and that is just not the case. '19-FEB-2011' is counted as being earlier than '19-JAN-2008', as strings sort alphabetically.

  • Get the Count for each row

    I'm trying to get the count for each row to total count for each month
    Something like this
    Hardware     |      Jan
    Monitors       |       5
    Processors   |      137
    Printers        |      57
    etc........
    How can I write a query for this. I can get the Hardware column but don't know how to get the next column.

    If you can provide more data like sample input DML statements it would have been wonderful..
    Assuming is , you need a pivot. Here is an article on basic Pivot..
    http://sqlsaga.com/sql-server/how-to-use-pivot-to-transform-rows-into-columns-in-sql-server/
    something like this may be..
    DECLARE @Input TABLE
    Hardware VARCHAR(20),
    [Date] VARCHAR(20)
    INSERT INTO @Input VALUES('Monitor', '01/01/2014'), ('CPU', '01/01/2014'), ('Monitor', '01/03/2014')
    , ('ABC', '01/01/2014'),('Monitor', '02/01/2014')
    ;WITH CTE AS
    SELECT Hardware, LEFT(DATENAME(M, [Date]),3) AS [MonthName] FROM @Input
    SELECT *
    FROM
    SELECT Hardware, [MonthName], COUNT(Hardware) AS Count FROM CTE GROUP BY Hardware, [MonthName]) a
    PIVOT (MAX([Count]) FOR [MonthName] IN ([Jan], [Feb])) pvt

  • How to get the Count of a logic?

    Hi,
    Very new to CRM. I am trying to get the count of "activity start time" that are greater than current time stamp. Count(activity start time) work. I don't know how to add the time stamp condition to this. I can't add this condition as filter.
    Appreciate any responses.
    Thanks

    Raghu,
    Thanks for the help. It works to get the count.
    The problem is, i have some other filters set and can't combine this filter. Here is my scenario:
    get all activities on a contact that have greater than x $ amount as assets. I need to find the number of future appointments for that contact and start time of first pending future appointment. All has to be in one report.
    My columns are for example : contact name, activity start time, end time, subject, next pending appointment start time, total future appointments, some other related fields from contact
    So when I add the filter that you had given, it will not give me all activities. I am able to achieve all this in seperate reports and unnable to get it in single one.
    Thanks,
    GiGi

  • SQ01 - SAP List Viewer - Ability to get the count of the output records

    Hello All,
    I have a problem with the SAP List Viewer output for an SAP Query.
    I have created a SAP query (SQ01) for a table. Its a basic query that queries on just one table (VTBFHA)
    When I run the query, for the output in the SAP List Viewer (ALV) format, Could anyone kindly help me figure out how to get the count of the number of records displayed in the output?
    For Eg: when we run the T code SE16, It gives us the number of records displayed in the output.
    Similarly, does anyone know if there is a way I could display the count of the number of records displayed in the output of the SQ01 query?
    I have tried checking the "Counter" in the basic list tab, but it does not give me the count.
    Any help will be greatly appreciated
    Thanks
    Subhani

    Yes there is a solution. Follow these steps
    Select your query
    Hit the button InfoSet Query
    Go to Edit->Settings->
    Check the box "Count in the Output list" in the Output tab
    Hit Save
    In pop up box select the user group
    hit enter
    Hit the back arrow (F3)
    now Execute the query
    You should be able to see the count in the output.
    The count will appear on the right most column of the output. If it does not go to the "Change layout" option and make sure it is part of the "Displayed columns list".

  • Select Count(*) from Sample_table - how to get the count using JDBC?

    Hi All,
    It would be glad if anyone could help me with this. The problem is that I have to get the 'count' of records selected from a arbitrary table say, 'sample_table'. Is that possible to form the SQL in JDBC as
    Select Count(*) from Sample_table
    and get the value of the count? If yes, how?
    Thanks in advance
    Prabz

    stmt = con.createStatement();
    ResultSet recordcnt_rs = stmt.executeQuery("Select Count (*) as record_ctr From Sample_table");
    recordcnt_rs.next();     
    record_ctr = recordcnt_rs.getInt("record_ctr");
    hope this helps.

  • How do I get the layout guides (A,B,C column headers and 1,2,3 Row Headers) to print with my spreadsheet?

    How do I get the Layout Guides (A,B,C column headers and 1,2,3 Row Headers) to print on my spreadsheet? They are invaluable for discussing the data with my clients over the phone.
    They appear while I am editing, but don't print with the spreadsheet. I know how to do it in Excel, but I am transitioning to Numbers. I can't imagine I have to type them into their own columns and rows. It must be a difference in vernacular that I can't find the solution in the User Guide. Can anyone help?

    Hi ktjobauer,
    Numbers is not Excel and Excel is not Numbers. Numbers is WYSIWYG (at least in File > Print and the actual printout).
    I can't imagine I have to type them into their own columns and rows.
    No, you don't. You can use the charm of Numbers to create cell references for your Excel clients.
    In this Numbers Table, I have added some extra Columns that you can hide later.
    Column B =COLUMN(A2)
    Column C =HLOOKUP(B2,'Table 1-1' :: $1:$2,2,FALSE)      [explanation later]
    Column D =ROW(B2)
    Column E =C2&D2
    Add those formulas to the first Body Row (below the Header Row) and Fill Down.
    Column C refers to another Table which you need only create once, to convert a Column number to a letter:
    and so on from 1-26, A-Z.
    You can move the second Table to another Sheet to hide it. Formulas will automatically adjust to keep the links between Sheets.
    Now in the first Table, select and Hide Columns B,C,D. Formulas will continue to work with hidden cells:

    Ian.
