sql - How to use a total of a computed column as a value in another query? -

-

background :- have scenario find out value of items have quoted on projects have been named preferred supplier , value of items not named for.

the tables have @ disposal dba.lead -> dba.a_quotelne columns decide whether items specified or not : "dba"."a_quotelne"."altlineref" if altlineref = 0 not named, if = 1 have been named. first line of each group of items contains 1 or 0. rest null.

example

        "leadno"    "lead_desc"     "lineno"    "calc_value"    "altlineref"    "calc_groupingref"         1           canary wharf        1           10          0               1000         1           canary wharf        2           16          null            1000         1           canary wharf        3           12          null            1000         1           canary wharf        4           12          1               1001         1           canary wharf        5           13          null            1001         2           rosente lane        1           14          0               1002         2           rosente lane        2           14          1               1003         2           rosente lane        3           12          null            1003         2           rosente lane        1           15          1               1004         2           rosente lane        2           267         null            1004         2           rosente lane        3           298         null            1004

i used following code split specified , non specified values apart, need total of each , somehow use computed total in larger report.

  select "dba"."lead"."leadno",         "dba"."lead"."lead_desc",         "dba"."a_quotelne"."quoteno",         "dba"."a_quotelne"."lineno",         "dba"."a_quotelne"."calc_value" * max("dba"."a_quotelne"."altlineref") on (partition "dba"."a_quotelne"."calc_groupingref") spec_value,         "dba"."a_quotelne"."calc_value" - spec_value nonspec_value   "dba"."a_quotelne",         "dba"."lead"   ( "dba"."a_quotelne"."leadno" = "dba"."lead"."leadno" )  group "dba"."a_quotelne"."altlineref",         "dba"."a_quotelne"."calc_groupingref",         "dba"."a_quotelne"."calc_value",         "dba"."a_quotelne"."quoteno",         "dba"."lead"."lead_desc",         "dba"."lead"."leadno",         "dba"."a_quotelne"."lineno"

the results wish achieve follows

    "leadno"    "lead_desc"     nonspec value   spec value     1           canary wharf            38          25     2           rosente lane            14          606

as aware little out of depth here, massively appreciated - , if has better suggestion on how split specified , non specified values apart please include that.

many in advance

your situation have quote lines altlineref , calc_groupingref defined on them. several rows might have calc_groupingref same value, 1 has correct value of altlineref (all other have null values).

here alternative way formulate query. inner query aggregates quote lines lead , calc_groupingref. in doing so, finds maximum value , sum of values. outer query combines information lead:

select l.leadno, l.lead_desc,        sum(case when maxref = 0 ql.val end) nonspec_value,        sum(case when maxref = 1 ql.val end) spec_value dba.lead l join      (select ql.leadno, sum(ql.calc_value) val,              max(ql.altlineref) maxref       dba.a_quotelne ql       group ql.leadno, cal_groupingref      ) ql       on ql.leadno = l.leadno group l.leadno, l.lead_desc;

along way, introduced table aliases make query easier understand.

i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution:

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
