sybase - how to select max top 10 (n) rows with there size? -

-

i have below query gets size of tables. intersted top 10 max size table there size.

how ?

select convert(varchar(30),o.name) table_name, row_count(db_id(), o.id) row_count, data_pages(db_id(), o.id, 0) pages, data_pages(db_id(), o.id, 0) * (@@maxpagesize/1024) kbs sysobjects o type = 'u' order table_name

searching similar: select top 10 max(datapages) sysobjects

edit:

also have size of indexes, adding sysindexes query enough or should add system table syscoments ?

writing such way giving me top table name:

select top 10 convert(varchar(30),o.name) table_name, row_count(db_id(), o.id) row_count, data_pages(db_id(), o.id, 0) pages, data_pages(db_id(), o.id, 0) * (@@maxpagesize/1024) kbs sysobjects o type = 'u' order table_name , kbs

this throwing error 

select top 10 data_pages(db_id(), o.id, 0) * (@@maxpagesize/1024) kbs , convert(varchar(30),o.name) table_name, row_count(db_id(), o.id) row_count, data_pages(db_id(), o.id, 0) pages sysobjects o type = 'u' order  kbs , table_name

this query works on ase 16.0 system:

select top 10 convert(varchar(30),o.name) table_name, row_count(db_id(), o.id) row_count, data_pages(db_id(), o.id, 0) pages, data_pages(db_id(), o.id, 0) * (@@maxpagesize/1024) kbs sysobjects o type = 'u' order kbs desc, table_name asc

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

mercurial graft feature, can it copy? -

-
there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
