Export data from Access to Excel

Hi,
I'm trying to export data from a table in Access to separate excel workbooks based on a conditional field. The code I have below errors on Runtime Error 3022: the changes to the table you requested were not successful becuase they would cause duplicate values. I think this refers to the zExportQuery but there is no primary key there so I'm not sure they there is this error.

Below is my code. Any help appreciated! Thanks.

Code:

---

Sub MonthlyUtil()

Dim qdf As DAO.QueryDef
Dim dbs As DAO.Database
Dim rstMgr As DAO.Recordset
Dim strSQL As String, strTemp As String, strMgr As String

Const strQName As String = "zExportQuery"

Set dbs = CurrentDb

' Create temporary query that will be used for exporting data;
' we give it a dummy SQL statement initially (this name will
' be changed by the code to conform to each manager's identification)
strTemp = dbs.TableDefs(0).Name
strSQL = "SELECT * FROM [" & strTemp & "] WHERE 1=0;"
Set qdf = dbs.CreateQueryDef(strQName, strSQL)
qdf.Close
strTemp = strQName

' *** code to set strSQL needs to be changed to conform to your
' *** database design -- ManagerID and EmployeesTable need to
' *** be changed to your table and field names
' Get list of ManagerID values -- note: replace my generic table and field names
' with the real names of the EmployeesTable table and the ManagerID field
strSQL = "SELECT DISTINCT EntityID FROM qryMonthRep;"
Set rstMgr = dbs.OpenRecordset(strSQL, dbOpenDynaset, dbReadOnly)

' Now loop through list of ManagerID values and create a query for each ManagerID
' so that the data can be exported -- the code assumes that the actual names
' of the managers are in a lookup table -- again, replace generic names with
' real names of tables and fields
If rstMgr.EOF = False And rstMgr.BOF = False Then
      rstMgr.MoveFirst
      Do While rstMgr.EOF = False

' *** code to set strMgr needs to be changed to conform to your
' *** database design -- ManagerNameField, ManagersTable, and
' *** ManagerID need to be changed to your table and field names
' *** be changed to your table and field names
            strMgr = DLookup("Entity", "Clients", _
        "EntityID = " & Chr(34) & rstMgr!EntityID.Value & Chr(34))
 
      ' *** code to set strSQL needs to be changed to conform to your
' *** database design -- ManagerID and EmployeesTable need to
' *** be changed to your table and field names
 
            strSQL = "SELECT * FROM qryMonthRep WHERE " & _
                  "EntityID = " & rstMgr!EntityID.Value & ";"
            Set qdf = dbs.QueryDefs(strTemp)
            qdf.Name = "q_" & strMgr
            strTemp = qdf.Name
            qdf.SQL = strSQL
            qdf.Close
            Set qdf = Nothing


 
             
                               
               

       

' Replace C:\FolderName\ with actual path

            DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, _
                  strTemp, "H:\SMART\HBG\Hospital Utilization\" & strMgr & Format(Now(), _
                  "ddMMMyyyy_hhnn") & ".xls"

            rstMgr.MoveNext
      Loop
End If

rstMgr.Close
Set rstMgr = Nothing

dbs.QueryDefs.Delete strTemp
dbs.Close
Set dbs = Nothing


End Sub

I wouldn't actually be creating a new query for each manager. Untested, but try this:

[vba]Sub MonthlyUtil()
Dim qdf As DAO.QueryDef
Dim dbs As DAO.Database
Dim rstMgr As DAO.Recordset
Dim strSQL As String, strMgr As String

Set dbs = CurrentDb
'NEW
Set qdf = dbs.QueryDefs("zExportQuery")

' I don't think you need this section at all
'strTemp = dbs.TableDefs(0).Name
'strSQL = "SELECT * FROM [" & strTemp & "] WHERE 1=0;"
'Set qdf = dbs.CreateQueryDef(strQName, strSQL)
'qdf.Close
'strTemp = strQName
strSQL = "SELECT DISTINCT EntityID FROM qryMonthRep;"

' not changing any data, so open snapshot rather than dynaset
Set rstMgr = dbs.OpenRecordset(strSQL, dbOpenSnapshot, dbReadOnly)
Do While rstMgr.EOF = False
strMgr = DLookup("Entity", "Clients", _
"EntityID = " & Chr(34) & rstMgr!EntityID.Value & Chr(34))

strSQL = "SELECT * FROM qryMonthRep WHERE " & _
"EntityID = " & rstMgr!EntityID.Value & ";"

qdf.SQL = strSQL
' changed to reference query name
DoCmd.TransferSpreadsheet acExport, acSpreadsheetTypeExcel9, _
qdf.Name, "H:\SMART\HBG\Hospital Utilization\" & strMgr & Format(Now(), _
"ddMMMyyyy_hhnn") & ".xls"
rstMgr.MoveNext
Loop
rstMgr.Close
qdf.Close
dbs.Close
Set rstMgr = Nothing
Set dbs = Nothing
Set qdf = Nothing
End Sub
