Hi Friends,

I want to select columns based on condition
I have a table like

Table:

ID~Phone1~Phone2~Phone3~Phone4~Phone5
1~99~88~0~0~77

Now I want to select only the column and its value that is greater than 0 that is

Expected result:

ID~Phone1~Phone2~Phone5
1~99~88~77

If all phonenumber is < 0 then should return ID alone.

Regards,
RK

Hi Friends,

Here is what I have tried,

SQL

DECLARE @query VARCHAR(1000)=null;
SET @query = 'ID';
IF((select phone1 from tablename where id = 1459) > 0)
    SET @query += ',phone1';
    IF((select phone2 from tablename where id = 1459) > 0)
    SET @query += ',phone2';
    ..
    ..
    ..
IF (@query IS NOT NULL)
exec('SELECT '+@query+' FROM tablename WHERE id = 1459');

I do not know whether the above solution is optimal or not but it gives me expected answer.So I selected the above method.

Hope this may help someone too.
