UPDATE  a AS a
  INNER JOIN c AS c  ON  a.id = c.id
  SET     a.total = 1
  WHERE b.x < c.y



this sql, in the table a total's field, insert the value 1 under certain 
conditions; in some rows the value already exists and will only insert 
in other lines;
is possible put in an array php only the id of the rows updated?

es nel caso sotto su 1  6 ho già il valore; con sql vado a d inserire
solo nella riga 3

example
table a
id     total
1       1 already there is
2	0
3	0 only here the sql will insert the new value
4	0
5	0
6	1 already there is
7	0
...
1000	0


I think is necessary, while sql loop the rows, when a row is updated,
capture the id and insert in the php array, but how?
