Hi,
I am creating a simple SPROC in .NET (SQL Server 2005) and I want to send the content of a DataTable to the pipe. I'm not sure how to do this (all this is still quite new to all of us!).
Pipe.Send takes a SqlDataReader or SqlDataRecord as an argument. However, the DataTable can only return a DataTableReader with CreateDataReader.
Is there a way to cast something into something else to make this work? Casting the DataTableReader to a SqlDataReader doesn't work.
Thanks!

You need to create a sql server agent job an run it daily. You can't run a trigger on on insert update and delete.

After executing a select query the data provider returns the value in a varchar field in a .NET Unicode string, how does it determine the encoding conversion to perform? My guess is that it's determined by the collation setting on the column, but I'm not sure? For example, if the collation is SQL_Latin1_General_CP1_CI_AS, the Provider converts from code page 1252 to Unicode.
Does anyone know for sure the strategy applied here?

I have configured the table with the unique constraints but now I want to catch the error generated by SQL and then display or give it a meaningfull way to handle.
In other words, when the error occurs in SQL, I need to redirect the user to another page.

To handel the error in your page use the

Hi,
In a relational database, I would to like to know the performance difference between of using a string and an integer as the primary key field for the tabl;e. Will a column field of integer be indexed faster than a string column field ?
Thanks

Yes, simply because the key will be smaller. The smaller the key the faster it can be indexed and retrieved because the index will be smaller overall and it won't have to pull so much data off the disk in order to scan the index.

Thanks
Besides integer is smaller than string, will implicitly
the indexing of integer is faster than string, if they are of
similar length ?
How about for the retrievel after indexing, should be same ?

Hi,
I have written a VB6 program that uses a datagrid bound to a ADO data control. I do the following:
Adodc1.ConnectionString = "DSN=" & m_objSentryDB.DSN & ";uid=" & strUserID & ";pwd=" & strPassword
Adodc1.RecordSource = strSQL
Set DataGrid1.DataSource = Adodc1
This is working fine, however, when I want to close the program, how do i CLOSE the connection opened by the ADODC control? I am using a sybase database, and they is basically one ghost connection on the server remaining after each use of the program. I looked for a 'close' method on the ADODC object, but to no avail.
Also, what is the correct way to refresh the grid after the underlying table has changed? I use adocdc1.refresh, but this seams to knock out the display properties of the grid (size, caption etc).
Any ideas?
thanks

i was talking how to do it by code in c#.
can you help me with an example?
i have 1 table: person_id, person_name
second table: number_id, person_id, telephone no:
the relashion is 1 to many.
how can i add a record that the person_id to be in both tables automatically like in microsoft access?
do i have to use the DataRelation?

I was giving a higher lever overview because you insert/update it as two single tables rather than one joined table. I assumed you already knew how to do that.
Here is a simple example:
SqlCommand cmd = new SqlCommand();
cmd.Connection = myConnection;
cmd.CommandText = "INSERT table1(person_id, person_name) VALUES (@person_id, @person_name)";
cmd.Parameters.Add("@person_id", 1);
cmd.Parameters.Add("@person_name", "Joe Bloggs");
cmd.ExecuteNonQuery();
cmd = new SqlCommand();
cmd.Connection = myConnection;
cmd.CommandText = "INSERT table2(number_id, person_id, telephone_no) VALUES (@number_id, @person_id, @telephone_no)";
cmd.Parameters.Add("@number_id", 10);
cmd.Parameters.Add("@person_id", 1);
cmd.Parameters.Add("@telephone_no", "+44 131 332 4455");
cmd.ExecuteNonQuery();
Does this help?

yes this does help but i wanted to treat them as already in the relationship.
imagine a microsoft access form: in this case I would add only the person_name and telephone numbers without adding the person_id from the child table manualy.in this case it would be copied in the second table automatically due to the relationship.
I want to create an update form like in access.
do you have any ideea?
thanks very much for your fast help.
ex:
person_id 1 (autoseed-i don't have to insert)
person_name micu valentin
number_id 1(autoseed-i don't have to insert)
person_id (to update i have to copy this from the form-this is my problem-he must be copied from the parent table)number 123455
