Column Null value

I have some table which has more than 200 columns.
Instead of running query for each column I want to know which column has all null rows.
Any help will be appreciated.
simam

Table has more than 100 K number of rows.
Excel will not work because of the limitation of rows.
simam
No, You need to copy only column names in excel sheet. WE dont want to do anything with ROW data. Please look at the query, only the highlighted part alone you need to concatenate. Hope this will help you.
Select Sum(Case when Col1 is not null then 1 else NULL End),
Sum(Case when Col2 is not null then 1 else NULL End),
Sum(Case when Col3 is not null then 1 else NULL End)

  • From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    From two given tables, how do you fetch the values from two columns using values from one column(get values from col.A if col.A is not null and get values from col.B if col.A is null)?

    Hi,
    Use NVL or COALESCE:
    NVL (col_a, col_b)
    Returns col_a if col_a is not NULL; otherwise, it returns col_b.
    Col_a and col_b must have similar (if not identical) datatypes; for example, if col_a is a DATE, then col_b can be another DATE or it can be a TIMESTAMP, but it can't be a VARCHAR2.
    For more about NVL and COALESCE, see the SQL Language manual: http://docs.oracle.com/cd/E11882_01/server.112/e26088/functions119.htm#sthref1310
    I hope this answers your question.
    If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all tables involved, and also post the results you want from that data.
    Explain, using specific examples, how you get those results from that data.
    Always say which version of Oracle you're using (e.g., 11.2.0.2.0).

    I must say, when it's all working it looks great and it is very user friendly (end-user that is, NOT for developers!) but before you get to that stage… please please Oracle invest some time making Web ADI a bit more logical an coherent, get the obvious bugs out, please let us not have to update BNE tables anymore to get things done.

  • Crystal Report - NULL values mapped to Column names in reports

    Hai,
    I am using rows of data retrived from the SQL Server 2005 Express and sometimes the column names are NULL , I want to set a default value to this NULL value and set it as Data axes label / Group axes values, can some one please help me with this issue.
    Thank you in advance.
    Vijay

    I resolved this issue myself, this can be set as other Data Labels, Group Label or Series Riser's properties too, left-click twice until the blank item is selected and then right click and select "Edit Axis Label" item and here it can edited with the new value(text).

  • Sql query slowness due to rank and columns with null values:

        
    Sql query slowness due to rank and columns with null values:
    I have the following table in database with around 10 millions records:
    Declaration:
    create table PropertyOwners (
    [Key] int not null primary key,
    PropertyKey int not null,    
    BoughtDate DateTime,    
    OwnerKey int null,    
    GroupKey int null   
    go
    [Key] is primary key and combination of PropertyKey, BoughtDate, OwnerKey and GroupKey is unique.
    With the following index:
    CREATE NONCLUSTERED INDEX [IX_PropertyOwners] ON [dbo].[PropertyOwners]    
    [PropertyKey] ASC,   
    [BoughtDate] DESC,   
    [OwnerKey] DESC,   
    [GroupKey] DESC   
    go
    Description of the case:
    For single BoughtDate one property can belong to multiple owners or single group, for single record there can either be OwnerKey or GroupKey but not both so one of them will be null for each record. I am trying to retrieve the data from the table using
    following query for the OwnerKey. If there are same property rows for owners and group at the same time than the rows having OwnerKey with be preferred, that is why I am using "OwnerKey desc" in Rank function.
    declare @ownerKey int = 40000   
    select PropertyKey, BoughtDate, OwnerKey, GroupKey   
    from (    
    select PropertyKey, BoughtDate, OwnerKey, GroupKey,       
    RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]   
    from PropertyOwners   
    ) as result   
    where result.[Rank]=1 and result.[OwnerKey]=@ownerKey
    It is taking 2-3 seconds to get the records which is too slow, similar time it is taking as I try to get the records using the GroupKey. But when I tried to get the records for the PropertyKey with the same query, it is executing in 10 milliseconds.
    May be the slowness is due to as OwnerKey/GroupKey in the table  can be null and sql server in unable to index it. I have also tried to use the Indexed view to pre ranked them but I can't use it in my query as Rank function is not supported in indexed
    view.
    Please note this table is updated once a day and using Sql Server 2008 R2. Any help will be greatly appreciated.

    create table #result (PropertyKey int not null, BoughtDate datetime, OwnerKey int null, GroupKey int null, [Rank] int not null)Create index idx ON #result(OwnerKey ,rnk)
    insert into #result(PropertyKey, BoughtDate, OwnerKey, GroupKey, [Rank])
    select PropertyKey, BoughtDate, OwnerKey, GroupKey,
    RANK() over (partition by PropertyKey order by BoughtDate desc, OwnerKey desc, GroupKey desc) as [Rank]
    from PropertyOwners
    go
    declare @ownerKey int = 1
    select PropertyKey, BoughtDate, OwnerKey, GroupKey
    from #result as result
    where result.[Rank]=1
    and result.[OwnerKey]=@ownerKey

  • How to clear alert when a null value is returned for a metric column?

    Hey all,
    Recently, I've encountered a problem about clearing alert when a null value is returned for a metric column. From Oracle official doc, it seems that NO_CLEAR_ON_NULL could be used for this propose. However, it doesn't.
    Here is the line from doc, you can see when NO_CLEAR_ON_NULL is set as FALSE, the null value will clear alert, and the default value for NO_CLEAR_ON_NULL is FALSE.
    NO_CLEAR_ON_NULL: This attribute is used to control severity clearing when a null value is returned for a metric column. It defaults to FALSE with the behavior that a null value ends up clearing previous alert severities. With a TRUE value for this attribute, null values will be skipped in severity evaluations without clearing the severity.
    TRUE | FALSE (default)
    STATELESS_ALERTS: This attribute if set to TRUE indicates to EM that alerts on this
    column will not have corresponding clears. This allows the UI to decide whether to
    allow users to manually clear alerts on this column.
    TRUE | FALSE (default)Here is my code for the metric,
    -- meta definition

    SQL*Plus is a CLI (Command Line Interface) client tool. It has a very limited vocabularly, allowing you to (primarily):
    a) configure its local environment (e.g. size of the terminal ito number of characters per lines)
    b) configure its bevahiour (e.g. spooling data to a file)
    c) defining substitution and bind variables
    And that's it. It is not PL/SQL. It is not SQL. It takes the PL/SQL and SQL you enter, and submit that to the Oracle server. (it does some basic parsing of the data to substitute variables and bind variables where applicable)

  • Problem in summation on a column with possible null values

    Hi,
    I want to do summation on a column.
    If I use <?sum(amount)?>, if there is any null value,its giving NaN as output.
    From the forum I got the below syntax
    <?sum(AMOUNT[number(.)!='NaN'])?>
    but it is also not giving me the expected result. Its always displays 0.
    I want some thing like sum(NVL(amount,0)). Could some body please help me out?
    Thanks in Advance,
    Thiru

    If the column has many, many null values, and you want to use the index to identify the rows with non-null values, this is a good thing, as a B*Tree index will not index the nulls at all, so, even though your table may be very large, with many millions of rows, this index will be small and efficient, cause it will only contain index entries for those rows where the column is not null.
    Hope that helps,

  • Column values shift towards left for null values when export to excel

    Post Author: pssuresh
    CA Forum: Exporting
    All,
    I have a strange problem when using crystal report 10 export through C# Code. Consider in a row there are 3 columns and i am exporting to excel. ex.Student_id,Student_name,Student_Section. If Student_name values are null, then student_section values get displayed under student_name. There is a column shift towards left when there are null values. If anybody has already faced this problem, please post ur answer.
    Note:  When i just export to excel directly from crystal report, it works fine. i face problem only when i export through .Net code. I guess it is the problem with some formatting through code. if any body has fix, let me know.

    Are you using the "Grand Total" option that comes with the view?.I don't think there will be any issue , it will ignore the null values while calculating the total.

    The records are failing to load with null column values.
    I tried:
    col10 nullif col10 ="(null)"
    My control file is:
    load data
    infile 'abc.txt'
    into table XX_data
    fields terminated by X'09' optionally enclosed by '"'
    TRAILING NULLCOLS
    ( col1,
    col2 nullif col2 ="(null)",
    col3)

    Sample data is tab delimited file. For some reason, it has problem reading the second date (+time) column in the same record when there are null values in preceding columns. It says:
    ORA-01841: (full) year must be between -4713 and +9999, and not be 0
    Col1     Col2     Col3     Col4     Col5     Col6     Col7     Col8     Col9     Col10     Col11     Col12
