Better watch out. I got voted down the other day for suggesting that the OP use the forums supplied by the third party vendor.

Hi,
I need to return column names only. My code works, but I am changing the initial column name to something more meaningful, like the ID field I changed to SKU like:
ID AS 'SKU'
Here is my code how I returned back only the column names:
' Create SQL statement
Dim strSQL = "SELECT ID AS 'SKU', ProductName AS 'Product Name' FROM bvc_Product;"
' Create instance of connection and command object
Dim conn As New SqlConnection(ConfigurationSettings.AppSettings("ConnectionString"))
Dim command As New SqlCommand(strSQL, conn)
Dim dr As SqlDataReader
Dim i As Integer
' Mark the command as a stored procedure
command.CommandType = CommandType.Text
' Execute the command
conn.Open()
dr = command.ExecuteReader(CommandBehavior.SchemaOnly)
For i = 0 To dr.FieldCount - 1
Response.Write("Column: " & dr.GetName(i).ToString() & "<br />")
Next
My problem is is that I need the result to return the original field name, and the new field name, in this case I need it to return ID and SKU, and ProductName and ProductName.
How do I do this?
Can someone please advise?
Regards
ma se

Hi
It is not possible to get actual column names if alias name is added. If you are passing SQL Statment from the code behind, you can write to split the query as array and extract using substring 'as' then you will get an actual column name. Make sure that you have added 'as' for every column. I think this is bit complicated.
Just try it out.

If transaction log is enabled, then you can try restoring from transaction log.
however i've never tried this. you have to refer to some articles on how to do.

Yes it may be possible to recover deleted files (if the disk space is not used by other files) with some data recovery tools.

As long transaction log is present, it is possible to recover. once is truncated or deleted, i don't think is possible.

Hi All,
There is a requirement to create a procedure with passing Table/View name, column names in a dynamic manner with a return of resultset, It is require both in SqlServer and Sybase.
For example I am creating here one procedure:
alter procedure dba.TestProc(in viewname varchar(30),in orderbycol varchar(30),in orderbytype integer)
/* RESULT ( column-name,... ) */
begin
if orderbytype = '1' then
execute immediate 'select '+orderbycol+' from '+viewname+' order by cast('+orderbycol+' as numeric)'
else
execute immediate 'select '+orderbycol+' from '+viewname+' order by '+orderbycol
end if
end
From above procedure I am getting the error when I am using in my .NET application that it is not returning Resultset.
Suppose I want to make a procedure for:
Select dynamicCol1, dynamicCol2 from dynamicTable
How I will create the procedure for above with passing dynamicCol1,dynamicCol2 and dynamicTable variable and how I will call in .NET application.
With regards

Hi
Try this in Northwind database. Assume you are passing two parameters @OrderBycol and @viewname from the front end.
use northwind<br />
go<br />
<br />
DECLARE @sql nvarchar(4000)<br />
DECLARE @OrderByCol nvarchar(4000)<br />
DECLARE @viewname nvarchar(100) <br />
<br />
set @viewname = 'Invoices' -- passed from front end <br />
set @OrderByCol = 'ShipName, ShipAddress' -- passed from front end <br />
<br />
SET @sql = 'SELECT ' + @OrderByCol + ' FROM ' + @viewname<br />
<br />
print @sql<br />
<br />
EXECUTE (@sql)
and make sure that you have given one space after SELECT in 'SELECT ' and also before & after the keyword FROM clause.

Thanks a lot.
I will try it. Have you any idea how I will create it in Sybase.
Is there any problem that to call the Procedure in front-end as it returns a result set not a single value?

Hi
I have not worked on Sybase.
I dont get you the last line ...

My web hotel has upgraded from MySQL 4.1.21 to MySQL 5.0.37. The only problem I have had with this is that a query doesn't return anything in the result any more:
select sum(i.FileSize) as TotalSize<br />
from Photos p<br />
inner join Images i on i.PhotoId=p.PhotoId and i.IsPublic=1<br />
where p.IsPublicArt=1 or p.IsPublicCommon=1
If I change "sum" to "max" or "count" the query return one row, with "sum" or "avg" it returns zero rows.
FileSize is int and can not be null.
If I test the query directly in the database (using phpmyadmin) it returns one row with all the aggregates.
My connection string looks like this (with a different uid and pwd of course): "driver={MySQL};server=mysql.loopia.se;uid=asdfasdf;pwd=asdfasdf;database=voidstation_com"
I have tried to add ";option=3" to the connection string, but that didn't make any difference.
The list of changes that the web hotel linked to:
http://dev.mysql.com/doc/refman/5.0/en/upgrading-from-4-1.html[^]
I don't see anything there that should affect this.
Anybody got any ideas?

I do not know about MySql.
But see what you can do with this hint:
sum will return a large value than count or max

Thanks for your reply.
When I use sum and run the query in phpmyadmin, the exact value that it returns is 609538140. It's larger than what count and max returns, but it's still way within the bounds of an int.
Anyway, it's not a problem with reading the value from the row, as the query doesn't even return a row. The result is empty. It doesn't contain any row to read from.
