is there batch script compiler available? have big batch file , want check syntax going wrong. using @pause , echo can check what's going wrong compiler better option. i suppose best find syntax checker, not real compiler, in batch many constructs compile @ runtime. each %var% expansion needs compile in moment of expansion, content change everything. possibility of self modifying code makes problem bit tricky. perhaps someone, write batch debugger, should possible.

i read description of std::nth_element @ http://www.sgi.com/tech/stl/nth_element.html template <class randomaccessiterator> void nth_element(randomaccessiterator first, randomaccessiterator nth, randomaccessiterator last); note preconditions are [first, nth) valid range. [nth, last) valid range. my question is: is valid call std::nth_element(a.begin(), a.end(), a.end()) ? if so, what's effect? doesn't violate preconditions above, anyway. anywhere in language standard (or other documents) stated nth must pointing element in a ? it's valid , probably, not guaranteed standard, null operation. given data, 2 preconditions become: [a.begin(), a.end()) valid range. [a.end(), a.end()) valid range. which both true, second interval empty though. standard 25.3.2/1: after nth_element element in position pointed nth element in position if whole range sorted. iterator in range [first, nth) , iterator j in range [nth, last)...

i can see single logical volume can mounted on 2 different file systems -- can explain me pros , cons of this? why doesn't linux throw error when happens? ex: /dev/mapper/vgep0-lvol12 9.9g 9.2g 243m 98% /lsmw /dev/mapper/vgep0-lvol12 9.9g 9.2g 243m 98% /oracle/ep0/oraflash in linux device can mounted multiple times. from mount(2) man page since linux 2.4 single file system can visible @ multiple mount points, , multiple mounts can stacked on same mount point.

courses (cid, cname, description) professors (pid, pname) teaching (tid, cid, pid, year, semester, department) students (sid, lname, fname, b_date, department) enrolled_stud (sid, tid, enrollment_date, grade, grade_date) the question: query students names have highest average: select a.sname,a.avg (select s1.sname,avg(e.grade)as avg students s1 natural join enrolledstudents e group s1.sid ) a.avg=(select max(a.avg)) you can see results in sqlfiddle , , can see doing wrong, , dont what! seem correct me... since it's study, i'll post hint first. think clause - a current row. of course a.avg equals max(a.avg) . update try following: select s1.sname, avg(e.grade) avg students s1 natural join enrolledstudents e group s1.sid having avg = (select avg(e.grade) avg enrolledstudents e group e.sid order avg desc limit 1);
