Question

I am using file upload control..in asp.net..storing files first in temp directory
and then after when user clicks on save I move files from temp to my desired location.
Problem is I have to used for loop and make 5 times trip to database for my insert query to insert 5 records.But I want to write single query for that.
I know that I can send my image name as well as image path comma seprated.but since i dont have enough knowledge of sql,I dont know how to split comma seprated files in sql and then using cursor insert them.So i request some one write me a sample query over here.so that i can proceed.

Use can pass dataset as xml to stored procedure and in stored procedure you can insert multiple rows in one go using openXML

C# code for passing dataset object as xml to stored procedure

         ...................................

    DataSet ds = new DataSet(); // assume dataset has records(in table object)
    string xmlString = ds.GetXml();

    SqlCommand cmd = new SqlCommand("your procedure name", "your Connection object");
    cmd.Parameters.Add(new SqlParameter("@XmlString",xmlString);
             ...................................

stored procedure, bulk insert using openXML

      ...................................

  DECLARE @XMLDocPointer INT    
  EXEC sp_xml_preparedocument @XMLDocPointer OUTPUT, @XmlString    

   INSERT INTO Employee
   (Name, Email, PhoneNo)    
   SELECT Name,Email,PhoneNo   
   FROM OPENXML(@XMLDocPointer,'/ROOT/DATA',2)    
   WITH  (Name VARCHAR(50),-- '@Name',     
         Email VARCHAR(50),-- '@Email',     
         PhoneNo VARCHAR(50) --'@PhoneNo')     

   EXEC sp_xml_removedocument @XMLDocPointer    
        ...................................

if you looking for split string in sql
then below is the sql function that you need to create in sqlserver

create function f_split(@SourceSql varchar(8000),@StrSeprate varchar(10))
returns @temp 
table(a varchar(100))
begin    
 declare @i int    
 set @SourceSql=rtrim(ltrim(@SourceSql)) 
 set @i=charindex(@StrSeprate,@SourceSql)    
 while @i>=1    
 begin        
  insert @temp values(left(@SourceSql,@i-1))        
  set @SourceSql=substring(@SourceSql,@i+1,len(@SourceSql)-@i)        
  set @i=charindex(@StrSeprate,@SourceSql)    
 end    
 if @SourceSql<>'\'       
 insert @temp values(@SourceSql)    
 return 
end
go

and how to call

select * from dbo.f_split('1,2,3,4,5',',')

and then using cursor you can insert all
