If I hard code my query...why do I need to built in my DB??

I have my query hard coded..

Public Sub querydef()
Dim db As Database, qdf As querydef, strSQL As String
Set db = CurrentDb
Set qdf = db.QueryDefs("Allot_Q")


Analyst = ""
For Each Item In Forms!AllotSearch_frm!lstEmployeeID.ItemsSelected
    If Analyst = "" Then
        Analyst = "'" & Forms!AllotSearch_frm!lstEmployeeID.ItemData(Item) & "'"
    Else:
        Analyst = Analyst & " , '" & Forms!AllotSearch_frm!lstEmployeeID.ItemData(Item) & "'"
    End If
Next
Analyst = "IN(" & Analyst & ")"


Org = ""
For Each Item In Forms!AllotSearch_frm!lstOrg.ItemsSelected
    If Org = "" Then
        Org = "'" & Forms!AllotSearch_frm!lstOrg.ItemData(Item) & "'"
    Else:
        Org = Org & " , '" & Forms!AllotSearch_frm!lstOrg.ItemData(Item) & "'"
    End If
Next
Org = "IN(" & Org & ")"

CostCenter = ""
For Each Item In Forms!AllotSearch_frm!lstCostCenter.ItemsSelected
    If CostCenter = "" Then
        CostCenter = "'" & Forms!AllotSearch_frm!lstCostCenter.ItemData(Item) & "'"
    Else:
       CostCenter = CostCenter & " , '" & Forms!AllotSearch_frm!lstCostCenter.ItemData(Item) & "'"
    End If
Next
CostCenter = "IN(" & CostCenter & ")"

Fund = ""
For Each Item In Forms!AllotSearch_frm!lstFund.ItemsSelected
    If Fund = "" Then
        Fund = "'" & Forms!AllotSearch_frm!lstFund.ItemData(Item) & "'"
    Else:
        Fund = Fund & " , '" & Forms!AllotSearch_frm!lstFund.ItemData(Item) & "'"
    End If
Next
Fund = "IN(" & Fund & ")"

PEC = ""
For Each Item In Forms!AllotSearch_frm!lstPEC.ItemsSelected
    If PEC = "" Then
        PEC = "'" & Forms!AllotSearch_frm!lstPEC.ItemData(Item) & "'"
    Else:
        PEC = PEC & " , '" & Forms!AllotSearch_frm!lstPEC.ItemData(Item) & "'"
    End If
Next

strSQL = "SELECT Distinct Final_Table.ID, dbo_tblOrgLook_master.Analyst, dbo_tblOrgLook_master.Org, dbo_tblOrgLook_master.OrgName, dbo_tblOrgLook_master.CostCenter, dbo_tblOrgLook_master.Fund, dbo_tblOrgLook_master.PEC, dbo_tblOrgLook_master.ProgramName, Final_Table.[Org Name:], Final_Table.CostCen, Final_Table.[Fund:], Final_Table.[Line Item:], Final_Table.[Item Number:], Final_Table.[Total Initial:], Final_Table.[BC1Change], Final_Table.[TotalBC1], Final_Table.[BC2Change], Final_Table.[TotalBC2], Final_Table.[BC3Change], Final_Table.[TotalBC3], Final_Table.[BC4Change], Final_Table.[TotalBC4]"
strSQL = strSQL & "FROM Final_Table LEFT JOIN dbo_tblOrgLook_master ON (Final_Table.CostCen = dbo_tblOrgLook_master.CostCenter) AND (Final_Table.PEC = dbo_tblOrgLook_master.PEC) WHERE dbo_tblOrgLook_master.Analyst " & Analyst & " AND dbo_tblOrgLook_master.Org " & Org & " AND dbo_tblOrgLook_master.CostCenter " & CostCenter & " AND dbo_tblOrgLook_master.Fund " & Fund & " AND dbo_tblOrgLook_master.PEC " & PEC

qdf.SQL = strSQL

End Sub
