java - Using a Local Temp Table and such using SimpleJdbcTemplate (or Spring) -

-

first off, admittedly, no dba...so sql-fu weak.

i working on project had pretty hefty report did 10 inner joins. when ran against prod data (sql server 2005) using sql studio management client, query wasn't barn-burner, returned in under 20sec. however, when ran through spring, 31min.

so, got our dba ninja on it, , pointed out query plan different because jdbc method use prepared statement, passing in variables parameters, whereas in client hard-coded. so, re-worked query.

the resulting query sets declare variables top, uses create local temp table, uses local temp table part of ultimate report query. said should able send part of same query string (compound query????). looks (obfuscated protect innocent):

declare @startdate datetime declare @enddate datetime  set @startdate = dateadd (dd, 0, datediff (dd, 0, '2013-03-01 00:00:00.000')) set @enddate = dateadd (dd, 1, datediff (dd, 0, '2013-08-08 00:00:00.000'))  create table #latest_blah_action (     fk_blah_timestamp datetime,      fk_blah_id varchar(10),      blah_other_thing varchar(10),     [latest updated date/time] datetime   ) insert #latest_blah_action select fk_blah_timestamp, fk_blah_id, blah_other_thing,     max(blah_other_timestamp) [latest updated date/time]  blahtable                         blah_another_thing = 'some value' ,    blah_other_timestamp between @startdate , @enddate group fk_blah_timestamp, fk_blah_id, blah_other_thing  select    -- bunch of fields   latest_blah_action   -- bunch of crazy inner joins , such

however it's not working. if run out of sql management studio, results. if run out of java code using spring's simplejdbctemplate, no error no results.

is possible run (compound???) query using spring, , if so, how? have them individually, part of transaction? maybe use other simplejdbctemplate?

css - Which browser returns the correct result for getBoundingClientRect of an SVG element? -

this svg contains rect overflows svg element: <svg id='svg' width='10' height='10'> <rect x='-10' y='-10' width='30' height='30'/> </svg> chrome 28 , opera 12 return getboundingclientrect() svg element width , height of 10. firefox 23 reports width , height of 30. correct? jsfiddle the relevant spec cssom , delegates svg spec if svg element not "have associated css layout box". haven't found definition of "having associated css layout box", correct result seem hinge on definition, getbbox returns 30x30 rect in browsers. this firefox bug fixed now, fix in firefox nightlies , should make through firefox 33 released on 14 october 2014. see bug 530985 details.
