subform does update on ms/access

I have a "framing" form where I have a control that, when changed, its contents change the "where" clause of a query. They do, and when I review the query, it is OK - the correct set of records is there. This query is the data source of a  subform, that should show the set of selected records.

However, even though I use the "requery" method:

   strSetSQL = "SELECT tabancasBase.codigoTabanca, tabancasBase.NomeTabanca, tabancasBase.Programa, tabancasBase.habitatTabanca, tabancasDemografia.projPop2014, ticketCA.fechoTicket, regioesGuineBissau.nomeRegia, sectoresGuineBissau.nomeSector, tabancasBase.codigoSector "
    strSetSQL = strSetSQL & "FROM ((regioesGuineBissau INNER JOIN sectoresGuineBissau ON regioesGuineBissau.codigoRegiao = sectoresGuineBissau.codigoRegiao) INNER JOIN (tabancasBase LEFT JOIN ticketCA ON tabancasBase.codigoTabanca = ticketCA.codigoTabanca) ON (sectoresGuineBissau.codigoSector = tabancasBase.codigoSector) AND (regioesGuineBissau.codigoRegiao = tabancasBase.codigoRegiao)) LEFT JOIN tabancasDemografia ON tabancasBase.codigoTabanca = tabancasDemografia.RefTabanca "
    strSetSQL = strSetSQL & " WHERE (((sectoresGuineBissau.codigoRegiao)='"
    strSetSQL = strSetSQL & Me.fld_regiao & "'));"
    Set Q44_selectTabancaDef = sireshDB.QueryDefs("Q44_selectTabanca")
    Q44_selectTabancaDef.SQL = strSetSQL
    Set Q44_selectTabancaSet = sireshDB.OpenRecordset("Q44_selectTabanca", dbOpenDynaset)
   
    Me.[sform_listaTabancas].Form.Requery


can anyone help?

I haven't ever seen this particular technique.  It might be not working because it isn't causing the subform to reload the actual query but merely rerun the existing query that it has in memory.

I use saved querydefs that reference form fields.  That doesn't require the query definition to be resaved each time.

So, the saved querydef would have the following where clause

Where sectoresGuineBissau.codigoRegiao = Forms!yourformname!fld_regiao

Another technique that I know works is to use SQL Strings as the RecordSource.  You would then replace the RecordSource --

Me.mysubformname.Form.RecordSource = strSetSQL

PERFECT solution. Thanks! (I have used the last option as I already had the SQL statement ready....
