sql server - Messed up SQL data - Select within update statement -

-

i accidentally ran query twice , points in database have messed (3000 records).

top 4 each result has fixed results points between last , 5th calculated (last 100pts).

click here more info

i need statement converting sql:

points = 100 + ((100 / (numberofresults - 4)) * (numberofresults - positionofresult))

how can select statement refer select , update table separately. doesn't work:

update    results r1 set       r1.points = 100 + ((100/((select top 1 r2.position results r2 r2.date = r1.date , r2.contestid = r1.contestid order r2.position desc)-4) * ((select top 1 r2.position results r2 r2.date = r1.date , r2.contestid = r1.contestid order r2.position desc)-r1.position)))     r1.contestid > 11 ,       r1.position > 4 ,       r1.position < (select top 1 r2.position results r2 r2.date = r1.date , r2.contestid = r1.contestid order r2.position desc)

i pre-calculate top values , store them in temporary table before performing update:

select     r1.date,     r1.contestid,     (select top 1 r2.position      results r2      r2.date = r1.date , r2.contestid = r1.contestid      order r2.position desc) topposition #temp     (select distinct date, contestid results) r1;  update results r set    r.points = 100 + ((100/((select topposition #temp t                                 t.date = r.date ,                                       t.contestid = r.contestid)-4) *                             ((select topposition #temp t                               t.date = r.date ,                                     t.contestid = r.contestid)-r.position)))  r.contestid > 11 ,    r.position > 4 ,    r.position < (select topposition #temp t                      t.date = r.date , t.contestid = r.contestid);

however, not sure how numberofresults , numberofplaces defined. selecting top position never calculating numbers. maybe can add select:

..., (select count(*)  results r2  r2.date = r1.date , r2.contestid = r1.contestid) numberofresults ...
