Finding the column names from a table.

I am on 10g
I would like to find out the columns of a table where there are null columns in a table.....this table contains about 300 + columns where i do not want to put where condition for all the columns
is there a way i can write a sql to find?
for a given table or the results set that i need to get, i will have same results for all the rows, so it
cant be like col1 is null on row1, but col2 is not null on row2 ...they are all identical....
example table, but it has 300 + cols
F_IND     H_IND     P_IND     DMA_IND
N     N
N     N
N     N
N     N          Thanks

select count(col1), count(col2), count(col3), ...
from your table;
The results with 0s are null throughout the table (or the table has no rows).

hi
You can use User_tab_columns or All_tab_columns
SQL>Select Table_Name,Column_Name From user_tab_columns
where lower(table_name) like '%emp%' or
lower(column_name) like '%dept%'

How to read the column name of a table from sap system using C#?

Hi!!
I am using SAP .NET connector and creating a windows application.
Now I wanna read the column name when a table name is given....
Connection is done, but I don't know the code to read the column names alone...
Can anyone help me with the code??

fine!!
So if i give the table name, which the RFC_READ_TABLE function module have, will it run properly? or i wanna change all the codes in order to support RFC_READ_TABLE function module?
Because from the beginning I was using BAPI_CUSTOMER_GETLIST function, but my client requirement is to use ERP function module RFC_READ_TABLE, he didn't give any table name also..
This is my code: What I have to change in this???
ECCDestinationConfig ECCDestination = new ECCDestinationConfig();
            RfcDestinationManager.RegisterDestinationConfiguration(ECCDestination);
            RfcDestination rfcDest = null;
            rfcDest = RfcDestinationManager.GetDestination(a);
                RfcRepository repo = rfcDest.Repository;
                IRfcFunction customerList = repo.CreateFunction("BAPI_CUSTOMER_GETLIST");
                IRfcTable addressData = customerList.GetTable("AddressTable"));
                int j = addressData.Metadata.LineType.FieldCount;
                for (int i = 0; i < j; i++)
                    RfcElementMetadata metadata = addressData.GetElementMetadata(i);
                    listallcolumn.Items.Add(metadata.Name);

Find the column name for a constraint

Hi Guru,

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 get only column names from different tables as single table columns

Hi All,
I have one requirement in which we want only column names from different tables.
for example :
I have three tables T1 ,T2, T3 having
col1 clo2 clo3 --> T1 ,
col3 col5 ,clo6 --> T2 ,
Clo6 col8 col9 --> T3
columns i want to get only all Column names from all table as single Resultset not any data from that how can i get that empty resultset
because this empty result i want to bind in datagridview(front end) as Empty resultset
Please tell me anyways to do this
Niraj Sevalkar

If I understand you want an empty result set, just with metadata. SET FMTONLY do the trick:
SET FMTONLY ON
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
SET FMTONLY OFF
Another alternative is to include an imposible contition
SELECT Col1, Col2, Col3, ....., Coln
FROM
T1 CROSS JOIN T2 CROSS JOIN T3
WHERE 1 = 0
If you are using a SqlDataAdapter in your client application. You can use the FillSchema method. the select command may be any select statement that returns the columns you want. Under the covers FillSchema will call SET FMTONLY ON.
If you are using SqlCommand.ExecuteReader you can pass SchemaOnly to CommandBehavior argument. SET FMTONLY ON is called under the covers. Again the select command may be any select statement that returns the columns you want.

Query the column names from Public database links

Greetings,
I would like to retrieve the list of all the column names from a public database link. A regular ALL_TAB_COLUMNS doesn't seem to be working.
Thanks
John9569

Hi,
I think your DBA needed to create a synonym for you to have access of that remote database view.
CREATE SYNONYM synonym_name
FOR view_name@db_link;Then you can find the column names by
DESC synonym_nameGuru's , please correct me If I am wrong.
Thanks

Column names from another table

Hi All,
I have a scenario where i need to get names of a column from another table
for eg,
Table EMP
EmpNo EmpName EmpContact EmpPhone
1 xyz [email protected] 345
2 abc [email protected] 897
3 ttp [email protected] 345
The column names of this table can be configurable from some other place and its value is stored in another table like
Table Config (2 Columns)
Column_Name Value
EmpName First name
EmpContact Email
EmpPhone Mobile
Now i want to fetch the values from Emp table but with column headers that are changed and have a value in Config table.
If a column name is not there in config table then the original column name should come.
As shown below
EmpNo First name Email Mobile
1 xyz [email protected] 345
2 abc     [email protected] 897
3 ttp [email protected] 345
Another eg, If EmpName is not changed and entered in second table , then i want to have the same name as the original EMP table has as shown below.
EmpNo EmpName Email Mobile
1 xyz [email protected] 345
2 abc     [email protected] 897
3 ttp [email protected] 345
In other words something like this,
select empno,
EmpName as (select value from config where column_name=EmpName),
               EmpContact as (select value from config where column_name=Empcontact),
               EmpPhone as (select value from config where column_name=EmpPhone)
     From EMP
Can some one please help me in providing a solution for this.
Edited by: 941386 on May 30, 2013 6:20 AM

Unfortunately, I think this is a job for dynamic sql ...
Build your "query" first:
(note this won't work "as is", fix the syntax - but you get the idea.)
lv_str := 'select empno,
EmpName as ' || (select value from config where column_name=EmpName) || ',
EmpContact as ' || (select value from config where column_name=Empcontact) || ',
EmpPhone as ' || (select value from config where column_name=EmpPhone) || '
From EMP;';
execute immediate lv_str;Not sure if there's a better way or not.
Only other way I can think of is to leverage the way UNION [ALL] works.
So the following query:
select a, b, c from dual
union all
select d, e, f from dual
/returns data in columns "named" : "a, b, c"
Effectively renaming columns d, e, f. You just need to turn your data on edge in that first query, then throw out the rows (I don't know how to get it to work, but perhaps somebody else does?)
[edit]
another thought is create a view over top of the table, query that view, then drop the view :P
that would work nicely - avoid the dynamic SQL. shrug

Set the column name of a table in a list box

is there any code to set the column name of a table in a list box at oracle devloper 6i?
pls help.

I dont want to go for pl/sql . It should work any table.You want Dynamic SQL without using PL/SQL? Tricky. I'm sure there's a possible way using some very complex and convoluted XML functionality of SQL but in reality you are asking for something that isn't natural to SQL queries, especially if you are expecting a dynamic number of columns to be produced for each row of data. SQL expects a table structure, including output formats, to be a defined number of columns with any number of rows, not a defined number of rows with any number of columns.
Perhaps if you explain why you need this sort of functionality then we may be able to offer a better solution.

How to find the form name from VA02 T.code

how to find the form name from VA02 T.code

Hi Rajyam,
I guess you are looking out for the formname which prints sales related documents.
If this is what you want,then go to the T-code NACE and select the option K1Sales activities and click on the Output Types button on the top.The new window has all the types of Output types listed.Select the most appropriate and double click on the Processing routines button in the left side screen.
The new window lists the program names and the forms associated with that output type.
In case you have any further clarifications,do let me know.

To find the lowest salary from a table

hello guys,
i need to find the lowest salary from a table. whats the easy way to do this.

How do you handle ties?
If you want multiple rows returned when there are multiple people with the same salary
SELECT *
FROM(
    SELECT a.*,
           rank() over (order by salary desc ) rnk
      FROM your_table a)
WHERE rnk = 1If you want to handle ties differently, use a different analytic function. Probably dense_rank or row_number.

How can I list all the column names of a table by programming?

Firstly, The function was given a parameter as table name.
Then, it will lists all the columns names of the table.

hi,
hope the below code helps u. Just take the headee which contains the field name and split it like below and compare it with the field name u want here 'last name'.
here,
'First name' will be in wt_filedata1 and remaining field names in wt_filedata2, so 'do' continues.
c_tab must be the separator, either , or + or tab etc..
CODE:
read table person into wl_header index 1.
do.
    split wl_header at c_tab into: wt_filedata1 wt_filedata2.
    if wt_filedata1 <> 'lastname'.
      cnt1 = cnt1 + 1.
      wl_header = wt_filedata2.
    else.
      exit.
    endif.
enddo.
Please reward if it is useful.
