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.

Procedure for Column and Table variable

Elena200612-Jun-07 21:54

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?

SQL query returning zero row in MySQL 5

Guffa12-Jun-07 8:57

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.
