Why not? What error is it showing?
Can you execute the query from Sql Managment Studio to verify that it is correct?
..and yes, the result of the query would be loaded into a single datatable; that's what a join would do. Can you show the code where you execute the sql and read it into memory?

The SQL=query does not accept variables from C# code. You'll have to find another way to do it. Thinking about it, it'll probably be simply called "Product" in the database-server, not "dtProduct". Try changing that

Dear Group Members,
I am using Lucene.net for building a search engine. In course of development I came across providing filters to the search.
As I went through the Lucene documentation I came across ChainedFilter. It is a way to combine multiple filters together. However this class is not available in any of the assemblies (ver 3.0.3). The same is confirmed by multiple blog-posts. But I didn't come across any post where it is mentioned, what can be the performant way to club multiple filters together and provide it to Search().
Can someone please provide some input related to this.
Regards,
Shubhanshu

You mean "minimized"? I wouldn't recommend that, as a minimized form should not be displaying stuff.
You might want to set the parent of the sub-form though;
fo.ShowDialog(this);

Quote: are you missing a using directive or an assembly reference?
Add the assembly (dll) where UserInfoaa is defined.
Make sure that that assembly does not have a "zone identifier" with the value of "Internet" (on the level of the NTFS file system).

Hi ALL !
I want to execute this by OledbDataReader when I want to take ... :
string CalcQuery = @"SELECT SUM(BuyAmount) From SubTblMetal WHERE IDMetal=" + int.Parse(txtId.ToString());
OleDbCommand cmdCacl;
cnnCalc.Open();
cmdCacl = new OleDbCommand(CalcQuery, cnnCalc);
OleDbDataReader dr;
dr = cmdCacl.ExecuteReader();
if (dr.HasRows==false)
{
txtBuyAmount.Text = "0";
throw new Exception();
}
else if (dr.Read())
{
txtBuyAmount.Text = dr[0].ToString();
}
But when my DataReader has not any row ,I have an error for the value of txtBuAmount.Text
please Help , how can get the value of Zero (0) , when dataRow has not any row(value).
Thanks a lot !
|
|
|
|

First off, please use a parameterized query rather than concatenating the value into the statement.
Next, don't trust HasRows.
Also, why is that throw in there?
As you are expecting at most one value, you might do better with ExecuteScalar and then test for DBNull.Value (for when ther are no matching records).
You'll never get very far if all you do is follow instructions.
|
|
|
|
|
Very nicely explained 
If You Never Try You’ll Never Know
|
|
|
|
|
I want To do This :
BuyAmount.Text = "0";
When there is No Row in dataReader
thanks
|
|
|
|
|
I understand, but are there ever no rows? Or do you get a NULL (DBNull.Value) when there are no matching rows?
Even if you do get no rows, it's better to handle that with an else on the other if. You don't need two ifs; you don't need to test HasRows.
HasRows is not a member of the IDataReader[^] interface so you can't count on it being in every database system you use (if you ever have to use multiple database system, like I do). Every time I've tried to use HasRows I got burnt.
You'll never get very far if all you do is follow instructions.
