| tryselect count(distinct O.KEY), COUNT(distinct p.KEY)==========================================Cursors are useful if you don't know sql.SSIS can be used in a similar way.Beer is not cold and it isn't fizzy. |

ODETAIL and PDETAIL will produce a kind of CROSS JOIN since they share same key value.

You probably miss one more join condition between ODETAIL and PDETAILselect count(O.KEY), COUNT(p.KEY) from ODETAIL odjoin PDETAIL p on p.KEY = od.KEY AND p.somecol = od.somecoljoin ORDER O on O.KEY = od.OKEYwhere O.SHID = '1057'
