Select among the columns

I have a table A contains two date file - date1 and date2.. Is there a way to select the latest date on this table for each row? Thank you.

You can user with the this query to find the greatest date in each row
select decode(sign(date1 - date2),1,date1,date2) from table_name

  • How to select even the column names of a table?

    Hello All,
    Is there a way to select even the column names of a table in the select statement?
    My select from a table (say X) is in a SQL* Plus script that gets invoked by application tier and displays data in the application tier window. User's can then copy the data into a spreadsheet and do their processing. However, I need to give them the column names too along with the data.
    Thanks,
    Chiru

    If there is a middle tier that is selecting and
    displaying the data, and that's what the users are
    copying from, the middle tier would have to address
    its presentation of the data to allow users to
    include column names. If this is a common task, the
    application should probably be modified to give users
    the option of downloading the data in a spreadsheet
    directly rather than forcing them to copy and paste
    data.Thanks for the reply.
    The users don't have to copy paste. The application tier has an options in the "Tools" menu item which allows them to copy the entire output to a file (in my case a txt file which is a pipe delimited). Then they have to do text to columns to get the data into each column of the spreadsheet. I could have directly called the stored procedures from the application tier and created ".csv" files and FTP'd them to the user's folders. However, I am having to go this round about because, I am not getting enough support from the LAN team in FTP'ing etc.
    OK I'll think of another workaround.
    Thanks,
    Chiru

  • How to use the column names generated from Dynamic SQL

    Hi,
    I have a problem with Dynamic SQL.
    I have written an SQL which will dynamically generate the Select statement with from and where clause in it.
    But that select statement when executed will get me hundreds of rows and i want to insert each row separately into one more table.
    For that i have used a ref cursor to open and insert the table.
    In the select list the column names will also be as follows: COLUMN1, COLUMN2, COLUMN3,....COLUMNn
    Please find below the sample code:
    TYPE ref_csr IS REF CURSOR;
    insert_csr ref_csr;
    v_select VARCHAR2 (4000) := NULL;
    v_table VARCHAR2 (4000) := NULL;
    v_where VARCHAR2 (4000) := NULL;
    v_ins_tab VARCHAR2 (4000) := NULL;
    v_insert VARCHAR2 (4000) := NULL;
    v_ins_query VARCHAR2 (4000) := NULL;
    OPEN insert_csr FOR CASE
    WHEN v_where IS NOT NULL
    THEN 'SELECT '
    || v_select
    || ' FROM '
    || v_table
    || v_where
    || ';'
    ELSE 'SELECT ' || v_select || ' FROM ' || v_table || ';'
    END;

    || v_insert
    || ') VALUES ('
    || How to fetch the column names here
    || ');';
    EXECUTE IMMEDIATE v_ins_query;
    END LOOP;
    Please help me out with the above problem.

    I Built the statement as required but i need the column list because the first column value of each row should be inserted into one more table.
    So i was asking how to fetch the column list in a ref cursor so that value can be inserted in one more table.
    >
    Then add a RETURNING INTO clause to the query to have Oracle return the first column values into a collection.

    I have created a Rank for Total sales by Region wise i.e RANK(SUM(Dollars By Region)) in a pivot table.
    My pivot table looks like this
    COLUMN SELECTOR: TOTAL US , REGION , DISTRICT , MARKET

  • How to increase the column width when viewing a spreadsheet created by a concurrent request

    I have created a BI Publisher template to display the output from scheduled discoverer reports. It contains sixty three columns and the heading for each one is a variable but, in order to fit these on the page, each column is about a half a centimeter wide.
    When I use the Preview Template option from the RTF file and select Excel the columns are automatically sized to accommodate the data (which is what is required). However, when I upload the template and run a concurrent request and view the output, each column is shown as half a centimetre in width so the user can see very little of the data without resizing all columns. We do not think that this will be acceptable to our users.
    We are using Excel 2010 in both cases.
    I have looked at this forum and tried a few things without success so any help will be gratefully received.

    for ebs 12.1.3 you can create excel template by bip desktop 11
    i used bip desktop 11.1.1.5 with ms office 2010 for create excel template for ebs 12.1.2 and 12.1.3
    using excel template based on what do you want to do - if report contains complex visualization or many merging of cell and etc

  • Extending the columns in Data Prep Editor

    Hi Gurus,
    Is there any way to create more than 20 columns in Data Prep Editor.
    Any help on this appreciable.
    Thanks..

    Hi,
    just to be complete, I would like to add that a popular obstacle on creating a rules file with many columns is that if the last column does contain only NULL values (at least for the first N rows), it often doesn't show up in the data prep editor. This is a situation also described in other threads around here.
    To solve this, just ensure that the LAST column in your data source doesn't contain any NULL values. Change the selection of the columns in your Rules Files in a order which ensures that columns with NULL values do not appear at the last column.
    Hope this helps.

  • MSSQLServer4 - Accessing columns from a select with the same name

    The following describes a problem I'm encountering using the MSSQLServer4 driver...I have the following 2 tables (greatly simplified):
    Create Table BOOK( BookId int, Name varchar(50), AuthorId int )
    Create Table AUTHOR( AuthorId int, Name varchar(30) )
    and my select is
    Select BOOK.*, AUTHOR.*
    From BOOK Inner Join AUTHOR On BOOK.AUTHORID = AUTHOR.AUTHORID
    As you can see, the ResultSet from this select will have 2 identically named columns called "Name". I realize I could use an alias to differentiate the column names, but then I must list out every column in each table (quite ugly). I had EXPECTED to be able to do a resultSet.getString( "Author.Name" ), but that doesn't appear to work either. Next, I thought I could use the ResultSetMetaData.getTable()/ResultSetMetaData.getColumnName() to determine the ordinal value, but getTable() always returns "". Is there anyway to distinguish these two columns without using an alias?
    Any help is greatly appreciated.

    Regards...MarcHi. getTableName() will never work because the DBMS doesn't send the necessary metadata with the result
    set that the driver would need to implement that call. If you get 'Name' for multiple column names, JDBC specifies
    that getXXX("Name") will always return the first such named column. The only non-alias way is to know
    the columns you're going to get in order, and just do getXXX(1), getXXX(2) etc.

  • How to show the columns dynamically in OBIEE report based on the selection?

    Hi,
    I have a requirement where the columns should be dynamically shown in report based on what we select in propmt page.
    I'm creating a report in OBIEE where i want to give an option to the end user to select the columns whichever he wants to see in the report.
    For example I have the following columns in the report already:
    Customer Name,
    Customer Number,
    Bank Account,
    Address
    I want to give an option to the user to select 'Customer Mail ID' dynamically and see the column to be displyed in the report along with the existing columns.
    Through 'Column Selector' user can select a single column at a time, but if he want to select more than one column, how can we do this ?
    Please help me out in resolving this issue.
    Thanks,
    Chaithanya.

    Hi Chaithanya,
    there's not a straight solution for this. You can create different analysis containing different number of columns and then directing the user to this analysis using Action Links or you can also use View Selector to switch from one view (analysis) to the other. But it's not going to be very flexible nor dynamic.

For example, if the current record displays "Region","position", and "salary", I would like to add an additional column called "compared to" in which I can display the "salary" measure from another specific fact record whose attributes I know.
    Is there a function/statement that I can use to achieve this?

    Hi,
    It is similar to bug which is raised in Timesten 11.2.2.2.. BUG 13896607 - COLUMN NAME MISSING FROM A VIEW IN TIMESTEN 11.2.2.2 . If you have MOS access then you can view about this bug. The bug is going to be fix in the future release. The bug basically indicates that we are not displaying the column name properly when select list contains complex expressions. The column itself can be accessed and values are displayed correctly.
    Regarding your issue "column TIME_DIFFERENCE not found" , I would suggest you to access the column by position, not by name like below
    I believe you are trying to access your column like below
    resultset.getString(“TIME_DIFFERENCE”)
    Instead of this you can use : -- resultset.getString(2) ( this position should based on the position of the column you are using in the query)
    Hope this helps.
    Regards
    Rajesh
