It is used by DBOBuilder.

The following table shows the DBOFlatSelect attributes:

For example:

<?xml version="1.0" encoding="UTF-8"?>
<DBOFlatSelect class="it.greenvulcano.gvesb.datahandling.dbo.DBOFlatSelect"
               name="Partners_FinalReport-select" type="dbo">
   <FieldFormatters id="0">
       <FieldFormatter field-id="1,2" terminator-char=","  type="field-formatter"/>
       <FieldFormatter date-format="yyyyMMddHHmmssSSS" terminator-char=","
                       field-id="3" type="field-formatter"/>
       <FieldFormatter field-id="4" type="field-formatter"/>
   </FieldFormatters>
   <statement id="0" type="select">
       SELECT m.CAMPAIGN, c.MSISDN, c.EVENT_TIME, c.EVENT
       FROM CAMA.CDR_EVENT c, CAMA.MESSAGES m, CAMA.PARTNERS p
       where m.ID = c.MSG_ID
       and p.ID = m.PARTNER_ID
       and p.ID = @{{PARTNER_ID}}
       and c.EVENT_TIME <= to_timestamp('@{{MIN_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
       and c.EVENT_TIME >  to_timestamp('@{{MAX_REPG_TIME}}','YYYY-MM-DD HH24:MI:SS')
   </statement>
</DBOFlatSelect>

will generate the output:
