Why you need to convert the datetime column?

My this statement works well:

select distinct(RefNo), transactdate, totalamount from SalesTransactionTable order by transactdate

i need to make run the query i posted
what data type is the field "fechagen"?

regarding: "i need to make run the query i posted"

SELECT distinct(id)

"distinct" is not a function - so it does not accept a parameter

"id" is usually a unique identity for each row
if "id" is unique, then "distinct" is utterly redundant

Some Simple SQL Rules to Live By and look for "DISTINCT is *usually* bad"
A good rule of thumb -- if you need a distinct list of values in a single column or two, DISTINCT is the way to go.  But if your results "don't look right" or you see some duplicate rows and can't figure out why, do NOT just add DISTINCT to your SELECT to "fix it" !!  Step back, look at your joins, and re-write your query properly.  Even worse, I've seen people simply add DISTINCT to all their SELECT's right from the start, to preemptively "avoid duplicates".  Not good.  (Side note: If you are a DISTINCT abuser, try adding meaningful primary keys to your tables).
The effects of DISTINCT in a SQL query
Yes, I think in real life, Distinct is really seldom used. But if you really know that the statement result is what you want to achieve, try this:

SELECT distinct(id),Convert(Datetime, fechagen, 103) , estatus,fechagen,proyecto,reqnum,rev,tipoorden,tipmater,proveedor FROM requis ORDER BY  Convert(Datetime, fechagen, 103)
