Looping thru Fields of a single row of data in a table

I am comparing the value (s) in a table that will always have a single row, but I need to check the value of different fields to see if it matches my criteria.

'Checks for which quarter needs to be updated in the tblSummaryQuartersFrozen
strSQL = "Select Year, FreezeQ1, FreezeQ2, FreezeQ3, FreezeQ4" & _
" FROM tblcurrent"
Set rs = curDB.OpenRecordset(strSQL)

see '>>>>> - also need to handle if the FreezeQ(i) = 0 - since they are checkboxes

and compare that field(FreezeQ & (i) and then check another table tblSummaryQuartersFrozen for the indicated quarter and is if the data already exists.

the problem I am currently having is it loops thru the first time on the strsql, but then get an "NO Current Record" error.

Private Sub CmdAppendFrozenQuarters_Click()
Dim curDB As DAO.Database
Dim strSQL As String, strSQL1 As String
Dim rs As DAO.Recordset, rs1 As DAO.Recordset
Dim i As Integer

If you have one row only, then there is no records to loop.

So cut it down to the For .. Next loop only.

but I need to compare the value of the fields within that row - so do you know the best method to check and see if any of the Freezeqtr = -1 and be able to handle if they = 0.

if FreezeQtr = -1 then

check the Quarter value in table Summary - if FreezeQtr1 = - 1 and summary.Qtr = 1 then move to the next FreezeQtr field to check for its value and loop thru -

Note Here is my latest attempt - however on the 2nd pass thru the loop it is not recognizing that the table has been updated from the previous pass

Private Sub CmdAppendFrozenQuarters_Click()
Dim curDB As DAO.Database
Dim strSQL As String, strSQL1 As String
Dim rs As DAO.Recordset, rs1 As DAO.Recordset
Dim i As Integer
Dim fld As Field

   On Error GoTo CmdAppendFrozenQuarters_Click_Error

Set curDB = CurrentDb
DoCmd.SetWarnings (False)

    Call _
        MsgBox("This function should only be performed after each Qtr End.", _
        vbCritical, "Quarterly Summary Update!!")
    
    'Checks for which quarter already exists in the tblSummaryQuartersFrozen
    strSQL = "SELECT Quarter" & _
                " FROM tblSummaryQuartersFrozen" & _
                " WHERE (((tblSummaryQuartersFrozen.[Year])=Year(Date())))" & _
                " GROUP BY Quarter"
    Set rs = curDB.OpenRecordset(strSQL)
    
    'Checks for which quarter needs to be updated in the tblSummaryQuartersFrozen
    strSQL1 = "Select Year, FreezeQ1, FreezeQ2, FreezeQ3, FreezeQ4" & _
            " FROM tblcurrent"
    Set rs1 = curDB.OpenRecordset(strSQL1)
    
    For i = 1 To 4
        If rs.RecordCount = 0 And rs1.Fields("FreezeQ" & (i)) = -1 Then
            curDB.Execute ("INSERT INTO tblSummaryQuartersFrozen" & _
                            " SELECT tblSummary.*" & _
                            " FROM tblSummary" & _
                            " WHERE (Quarter = '" & i & "') And ((tblSummary.[Year])=Year(Date()))")
   
        ElseIf rs.RecordCount > 0 And rs1.Fields("FreezeQ" & (i)) = -1 And rs.Fields("Quarter") = (i) Then
            curDB.Execute ("INSERT INTO tblSummaryQuartersFrozen" & _
                            " SELECT tblSummary.*" & _

Still getting no current record on second pass

still looking for a simple solution.

Can you post table structure? At what point do you exit the rs?
dim i as integer
for i = 0 to rs.fields.count -1
if rs.fields(i).name like 'freezeqtr*' then
if rs.fields(i).value = somevalue then
next i
else
exit for
endif
endif
next i
roughly speaking.

That's because you aren't updating anything. Your SQL inserts new records.
