How to get datatype and label of columns in a record group

Hi all,
I need to create a generic block which displays data of any query. For this, I was thinking at runtime I'll create a recordgroup. For this I was hoping to get the datatypes and label of various columns in the records.
Please help me in this regard
Thanks

Hi everyone,
Can you please tell me that Is it possible to get the datatype and name of columns of a recordgroup during run-time or not. So that I don't waste my time in searching for this solution. If you are not getting my question then please let me know but I need this help very badly.
Thanks

How to Get ZERO and Non-ZERO Values in rowcount using Group by?

Dear All,
How can I get Non-ZERO and ZERO row count values in SQL using Group by? I can get non-zero values but when I want NULL should be returned to non-zero values it is ignoring ZERO values in output?
Any hint?
Thanks

Something like
select count(case col
                when 0
                then 1
              end) zero_count,
       count(case nvl(col,1)
                when 0
                then null
                else 1
              end) nonzero_countRegards

After the call of the methods GET_COLUMN_WIDTH or GET_ROW_HEIGHT
You need to add this command :
CALL METHOD cl_gui_cfw=>flush.
This will send back from the SAPGUI to your ABAP program the new values.
Found in this Thread : Method GET_ROW_HEIGHT

How to get ALV Display with First column alone in sort

How to get ALV Display with First column alone in sort

HI,
You can build Internal Table and send this to the parameter "IT_SORT".
eg:
"the sorting Internal Table structure is as whown below.
DATA: t_sort_info type slis_t_sortinfo_alv.
"Build the Sort Internal Table
t_sort_info-fieldname = 'CARRID'.
t_sort_info-subtot = 'X'.
append t_sort_info.
t_sort_info-fieldname = 'FLDATE'.
t_sort_info-subtot = 'X'.
append t_sort_info.
Then pass this "IT_SORT_INFO" table to the Function module "Reuse_alv_*". (Note send the body of the Internal table only like "<b>IT_SORT = IT_SORT_INFO[]</b>".
Here i am making ALV output sorted on CARRID & FLDATE.
You can specify only the First Column name for sorting.

Hello Jouko.
You can go into View > Toolbars and select the ones you want to see. If you can't see the menu bar you can simply tab ALT on your keyboard (I think F10 works too) to show it.

I think you want to get the latitude and longitude information of client accessing the web application. In the web application you cannot directly get the client location information as the nature of the web application is different from windows applications.
I advise you to develop a Silverlight component and in that Silverlight component use geolocation classes to get client location. Please refer this article for getting data in Silverlight http://www.c-sharpcorner.com/UploadFile/82b980/getting-geo-location-of-user-in-silverlight/
And once you get the location information you can send that data back to ASP.net webpage or call any javascript method as shown here http://ovaismehboob.wordpress.com/2013/06/22/bridging-data-between-asp-net-and-silverlight/
Hope this helps!

How to fetch Quartile and Comp Ratio columns

Hello all
How to fetch Quartile and Comp Ratio columns which are present in Enter and maintain -> Assignment screen -> Salary screen.Are they direct columns from any table or calculation columns.
Someone please suggest me how to fetch those columns
Thanks in advance

Can anyone help me in writing a procedure/dynamic SQL to fetch the column where the junk values appears and its value. Eg: If emp table contains ID and Name columns, and ID column contains junk values, the result should be the Id column and the junk value/s. It should be dynamic because next time if the other column contains junk values(like $,%...), the query should display the other column too..1. define "junk" values.
2. usually it does not matter what values are in ID, because it is used internally by application, to maintain uniqueness or relations, not having any semantical meaning. End users usually should not see IDs, such IDs are generated automatically. There is no need to cleanse them from "junk" values.
3. If you made a typo, and you are looking for "junk" values in Name column, it is a different story. You can use TRANSLATE to search such values, as already advised, translating all "junk" characters to one "junk" character and searching for the latter.
select id, name from T where translate(name,'?@#$%^<>','~~~~~~~~~') like '%~%';
