C# VS 2005 - SQL Query Parameters to an ODBC DataSource

[jcrcarmo]

Hello everyone,

I used to have my MS Access 2002 DataBase placed in my application folder and connect to it through an OLEDB connection. Everything worked fine.

Now I decided to create an ODBC DataSource and suddenly I'm not able to pass parameters to the SQL Query the way I used to with the OLEDB connection.

Here's a sample code of the SQL Query and C# code on my form:

FillByClienteDataNumero query:

SELECT Data, Cliente, Tipo, Número, Espécie, Lote, Análise, Preço
FROM qryALL1
WHERE (Cliente = ?) AND (Data >= ?) AND (Data <= ?) AND (Tipo = ?)
ORDER BY Data, Número


Form code:

private void btnSeekBA_Click(object sender, EventArgs e)
{
try
{
this.qryALL1TableAdapter.FillByClienteDataTipo(this.sascrDataSet.qryALL1, cbCliente.Text, new System.Nullable<System.DateTime>(((System.DateTime)(System.Convert.ChangeType(DataIni.Text, typeof(System.DateTime))))), new System.Nullable<System.DateTime>(((System.DateTime)(System.Convert.ChangeType(DataFin.Text, typeof(System.DateTime))))), "Boletim");
}
catch (System.Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
}
}


Any ideas why the above SQL query and code work with an OLEDB connection but not with an ODBC DataSource? Thanks a million!

JC.

You can't use '?' when using an ODBC Datasource. Instead you need to use '@ParamName'.

Hope this helps.
