Hello,
I have created 3 functions to insert, update and delete an Access
database record. The Insert and the Delete code are working fine.
The update is not. I checked and my database has all the necessary
records in it when testing it. I get the error "No value given for one
or more required parameters." when I try to update the database.
Can you tell me what am I doing wrong?
Thanks,
Miguel

Hi Miguel:
This is a Friday afternoon guess:
I believe with the OLE-DB provider parameters are based on position,
not name. Try adding an additional OleDbParameter for the @news_id in
the WHERE and see what happens.

Hi,
I did that:
' Set Query and Command
Dim queryString As String = "UPDATE [t_news] SET

[title_en-GB]=@title_enGB, [text_pt-PT]=@text_ptPT,

.Add(New OleDbParameter( "@text_enGB ", "Test UPDATE - text EN"))
.Add(New OleDbParameter( "@publication_d ate",
DateTime.Now.To String("dd-MM-yyyy HH:mm:ss")))
End With
I get the error: "Cannot update 'news_id'; field not updateable."
Remember that news_id is the primary key on my Access database and set
as "AutoNumber "
Then I tried the following query as i don't need to change the news_id
field:
Dim queryString As String = "UPDATE [t_news] SET
[title_pt-PT]=@title_ptPT, [title_en-GB]=@title_enGB,
[text_pt-PT]=@text_ptPT, [text_en-GB]=@text_enGB,
[publication_dat e]=@publication_d ate WHERE ([t_news].[news_id] =
@news_id)"
I don't get any error but there is no change in data!!!! And record 5 is
there!
I even placed a Response.Write( "Done") in the code:
' Update Record
dbConnection.Op en()
Try
dbCommand.Execu teNonQuery()
Finally
dbConnection.Cl ose()
Response.Write( "Done")
End Try
And it is displayed "DONE"!
My INSERT and DELETE codes are working fine.
What is going on with this UPDATE code?
Thanks,
Miguel

The @news_id parameter is getting populated with the publication date
- so the UPDATE statement never finds the record. As I mentioned in
the first reply, parameters are resolved by position for the OleDb
provider.
In other words:
OleDbParameters are not resolved by name.
OleDbParameters are resolved in the order they are added to the
OleDbCommand.
If your UPDATE looks like this:
UPDATE [t_news]
SET
[title_pt-PT]=@title_ptPT,
[title_en-GB]=@title_enGB,
[text_pt-PT]=@text_ptPT,
[text_en-GB]=@text_enGB,
[publication_dat e]=@publication_d ate
WHERE ([t_news].[news_id] = @news_id
Then you need to add to dbCommand.Param eters in the same order the
params appear in the query:
..Add(New OleDbParameter( "@title_ptP T", "Test UPDATE - title PT"))
..Add(New OleDbParameter( "@title_enG B", "Test UPDATE - title EN"))
'
' other params
'
..Add(New OleDbParameter( "@news_id", 5))
