This user[^] had the same problem.
A question that occurs to me is why it's using the Named Pipes driver. I can't recall whether Named Pipes is enabled by default on a new installation - I didn't think it was. I would have expected it to select Shared Memory. You could try checking to see whether there are any aliases configured in the Client Configuration tool (cliconfg.exe).

if any one know the code to view the tables in access database and display the data from any table plz send it quickly
|
|
|
|
|
What are you trying to accomplish and what language do you want to use?
|
|
|
|
|
to view tables try SELECT NAME FROM MSYSOBJECTS WHERE TYPE = 6
then run through the recordset one by one and use SELECT * FROM RECORDSET.Fields(0).Value

in a project i need some data for reporting, when i use same sentence in SQL server 2000 there is no problem, but in access i get "join clause error"
Select Sentence is here.
SELECT USR.USER_FULLNAME, CMP.C_COMPANYNAME, CMP.C_COUNTRY, CLRS.*,ORD.* FROM ORDERS ORD <br />
INNER JOIN COMPANIES CMP ON ORD.O_CUSTOMERID = CMP.C_COMPANYID <br />
INNER JOIN COLORS CLRS ON CLRS.C.ORDERID = O.O_ORDERID <br />
INNER JOIN USERS USR ON USR.USER_ID = ORD.O_WHOGET <br />
<br />
WHERE 1=1 ORDER BY ORD.O_ORDERDATE
 What s wrong ? ? ?
|
|
|
|

in Access SQL you have to set opening brackets after the from and closing after each join, when you have more than one join in the select.
you can also set the access mdb to ANSI 92 syntax (SQL Server) in extras/options/tables,querys then you dont have to set the INNER or the brackets.

thank u thomas for replaying,

I have posted this problem a few times now in other areas. I have received some repsoinses but all suggestions fail. I have placed many statments in the code to verify that the data is being read. IT is. The only issue is the dataBind statement. I'm getting very frustrated!
I have many examples of how to bind a dropdownlist but NONE match the code that is generated in VS .NET. Since I am new to .NET and web programming I am having difficulty following the gerneated code. I am convinced my problem is in the way I am binding the data. The eror I get is
"Index 0 is not non-negative and below total rows count."
and it ocurs in the following line
DropDownList1.DataBind();
Here is some of the code. If you are intereseted in helping me I can post all of it.
<br />

if (!Page.IsPostBack) <br />

Just a shot in the dark as I'm a sleft-taught hobbiest, but I would write your try catch like this:
private void BindListToDropDown()
{
try
{
oleDbConnection1.Open();
OleDbDataReader OleDbReader = this.oleDbSelectCommand1.ExecuteReader();
DropDownList1.DataSource=OleDbReader;
DropDownList1.DataTextField = "AirportName";
DropDownList1.DataValueField="AirportID";
DropDownList1.DataBind();
oleDbConnection1.Close();
}
catch(OleDbException ex)
{
Notice I don't close the connection until after the DataBind.
Let me know if that works.

Didn't work.
Thanks for the effort! i think it has something to do with the reader. Most examples I find do not use the reader.

Ok, it ws a shot in the dar.
Does the error point to either one of these lines of code?
DropDownList1.DataTextField = "AirportName";
DropDownList1.DataValueField="AirportID";

I am surprised that the previous code didn't work. I tried it using the pubs database and it worked fine. Make sure you close the database after calling DataBind. I tried closing before and got an error.
Following is my code:
<br />
private void BindListToDropDown()<br />
{<br />
string query = "select * from Authors";<br />
SqlCommand cmd = new SqlCommand(query, conn);
conn.Open();<br />
SqlDataReader dr = cmd.ExecuteReader();<br />
this.DropDownList1.DataSource = dr;<br />
this.DropDownList1.DataTextField = "au_lname";<br />
this.DropDownList1.DataValueField = "au_id";<br />
this.DropDownList1.DataBind();<br />
conn.Close();<br />
}<br />
|
|
|
|
|
If you want to bind the data to the dropdownlist you will need to use the dataset fill function.
Page_Load
sqlDataAdapter1.Fill(dataSet11);
DropDownList1.DataBind();
that's it!
Hope it helps...

Tried this and got the message
An invalid data source is being used for DropDownList1. A valid data source must implement either IListSource or IEnumerable.
Thanks for the effort!

Hello,
I have a problem with Interbase/Firebird database. I need to monitor the changes in database in specific select. Therefore I have created a view and a trigger after_update on that view. But if there´s an update made directly on the table which is included in the view, an event is not raised. It is raised only when I make the update on the view. This behavior seems to me strange.
I thank you for ideas.
|
|
|
|
|
Hey dats not a great problem. Its the property of a view. If u create a trigger in table dat will perfectly work for a view. But in case of creating a trigger for a view it will not work on a table as only changes done on view can have an impact on the table but not for the triggers raised.
|
|
|
|
|
Thanks for your reply, but I think it doesn't solve my problem. I want to database raises the event only if some of the columns included in my view are updated.
For example: I have got two tables in database. T1 and T2. T1 consists of columns C11 and C12, T2 constists of columns C21,C22,C23,C24.
The view is:
Select C11, C22, C23 from T1 one, T2 two where one.C12=two.C24
I want to create trigger, which is raised when some of C11,C22 or C23 are updated.
Of course I can create a trigger on both tables, on event notification refresh view and check if it changes, but this the way I'd like to avoid because of much code writing and much data downloading.
