Selection String still applied to Recordset

[jcfowl]

2 programers have 2 different ways of opening recordsets.

1st way - retrieve 1 record to Update

With DataEnvironment1.rstblLabs
        If .State = adStateOpen Then .Close
        .Open "SELECT * FROM tblLabs WHERE pkLab = " & p_pkLab, _
                , adOpenStatic, adLockOptimistic

2nd way - retrieve all records to fill a combobox
after the 1st way has already happened

With RS
        If Not .State = adStateOpen Then
            .Open , , adOpenStatic, adLockOptimistic

When the second query to this table is executed the only
record retrieved is the one from the 1st query. Is there any
way to clear out the selection string from the 1st query and
just retrieve all the records without passing a new selection
string? This code is everywhere in the program so a major
code change would be good to avoid.
