Disconnected Recordset Problem

I'm having a problem with a function I wrote.  Basically what it needs to do is run a select statement on one mysql database, if it returns empty, run the same select statement on a different mysql database.  The function then returns the recordset. The recordcount of the recordset is always -1.   If I take out     oDB.disconnect()   &  del oDB, it works.  Do I have to close the connection and delete the db object?  

def getRecordSet(conStr, sql, sysInfo):
    localDb = ""
    oDB = clsAdo()
    
    if (conStr.find("config") <> -1):
        localDb = sysInfo.configDbLocal
    elif (conStr.find("spd") <> -1):
        localDb = sysInfo.spdDbLocal
    
    if (localDb <> ""):
        if ( oDB.connect(localDb) == False ):
            displayErrorMsg("getRecordSet", "smt_utility.py", "Could not connect to the Database.", 1)
 
 
        oRS = oDB.getResultSet(sql)[0]
 
 
        if (oRS.EOF):
            oDB.Disconnect()
            if ( oDB.Connect(conStr) == False ):
                displayErrorMsg("getRecordSet", "smt_utility.py", "Could not connect to the Database.", 1)
 
    
            oRS = oDB.getResultSet(sql)[0]
 
            
    else:
        if ( oDB.connect(conStr) == False ):
            displayErrorMsg("getRecordSet", "smt_utility.py", "Could not connect to the Database.", 1)
 
  
    oRS = oDB.getResultSet( sql )
    
    oDB.disconnect()        
    del oDB
    return oRS
