i have code here: select c.case_code,coalesce(c.case1, c.case2) case_def,aspm.userid cases c left join aspnet_membership aspm on c.case_def = aspm.userid and well, since there alias in on clause, won't recognize case_def. what need is, need take non null value between case1 , case2 , need left join in query. how do this? in advance. select c.case_code,coalesce(c.case1, c.case2) case_def,aspm.userid cases c left join aspnet_membership aspm on coalesce(c.case1, c.case2) = aspm.userid you can't specify alias used in select clause elsewhere in query. however, dbms' accept that.

the util/ordering module contains comment @ top of file fact bound of module parameter constrained have exactly bound permitted scope said signature. i have read few times ( here instance) optimization allows generate nice symmetry-breaking predicate, can grasp. (btw, respect the said post , right infer exactly keyword in module parameter specification here enforce explictly exact bound (while implicit in pre-4.x alloy versions)?) however, comment contains part not seem refer optimization issue has semantic flavour: * technical comment: * important constraint: elem must contain atoms permitted scope. * let analyzer optimize analysis setting fields of each * instantiation of ord predefined values: e.g. setting 'last' highest * atom of elem , setting 'next' {<t0,t1>,<t1,t2>,...<tn-1,tn>}, n * scope of elem. without constraint, might not true ord.last * subset of elem, , domain , range of ord.next lie inside elem. so, not understa...
