Run time error 3021 - EOF or BOF is true or the cu

问题:

rst.Open "SELECT * FROM Equipas WHERE ([ID - Funcionário] LIKE '" & idfunc & "' AND [ID - Tarefa] LIKE ' " & idtask & "' );", CurrentProject.Connection, adOpenDynamic, adLockOptimistic
rst.Delete adAffectCurrent
rst.Update
rst.Close

I receive the runtime error 3021 however the query is not empty.

Double check that point.

Dim strSelect As String
strSelect = "SELECT * FROM Equipas " & _
    "WHERE ([ID - Funcionário] LIKE '" & _
    idfunc & "' AND [ID - Tarefa] LIKE ' " & idtask & "' );"
Debug.Print strSelect
rst.Open strSelect, CurrentProject.Connection, adOpenDynamic, adLockOptimistic
If rs.BOF And rs.EOF Then
    MsgBox "recordset is empty"
Else
    rs.MoveLast
    MsgBox "recordset contains " & rs.RecordCount & " rows"
End If
'rst.Delete adAffectCurrent
'rst.Update
rst.Close

If that version of the code tells you "recordset is empty", go to the Immediate window (Ctrl+g) to examine the SELECT statement the code built. You can copy the statement text and paste it into SQL View of a new Access query for testing.

My best guess is the query returns no rows because it includes a space just before the value of idtask, and no [ID - Tarefa] values match space plus idtask:

idfunc & "' AND [ID - Tarefa] LIKE ' " & idtask & "' );"
