i have this query that i want to fill its result in a data table

VB

Dim datenow As Date = Date.Now.Date

        Dim sql As String = "SELECT DISTINCT cmp_user_id FROM tbl_campaign WHERE cmp_date =#" & datenow & "#"

i use this method to fill it in a data table :

VB

Public Shared Function ExecuteSelect(ByVal query As String) As DataTable
      Dim xx As DataTable = New DataTable()
      Using a1 As New OleDbDataAdapter(query, ConnectionString)
          a1.Fill(xx)
      End Using
      Return xx
  End Function

how could i fix the query or the method to fill the datatable so i could use each data returned alone thanks

Hi

You have a problem in your query string please change your query:

VB

Dim datenow As Date = Date.Now.Date
 
        Dim sql As String = "SELECT DISTINCT cmp_user_id FROM tbl_campaign WHERE cmp_date =#" & datenow.ToString() & "#"

But I suggestion to you check the cmp_date data type from your database and be sure it is a DateTime after you should check the format of this field, for example if your cmp_date fields format at database is "dd/mm/yyyy" you should set this format on your datenow variable too ;)

Best Regards.
