SQL server Update using JOIN -

-

i used command in sql server update table using maximum data in other table innerjoin 

        update dbo.table2         set table2.lastgrantdate = max(table1.plannedprojstartdate)                  table1 inner join table2         on table2.serial = table1.fundingestablish

but doesn't work

it workes when use without max()

any way solve ??

you need use subquery. here 1 way:

    update t2     set t2.lastgrantdate = t1.maxppsd     table2 t2 inner join          (select fundingestablish, max(plannedprojstartdate) maxppsd           table1           group fundingestablish          ) t1          on t2.serial = t1.fundingestablish;

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...
