SQL Server Trigger on INSERT always ROLLED BACK -


i want create trigger not allow past client out usa.

so code is:

create trigger location_tr  on t1 insert, update begin     declare @country varchar(50)      set @country = (select country inserted);      if @country <> 'usa'     begin         print 'you cant add user out of usa!'          rollback transaction     end     else         commit transaction end

so now, can't update or insert on table t1.

i guess i'm going wrong commit/rollback commands. need help. thanks

the first issue trigger not support multiple rows. should use exists instead of setting value of variable. along these lines.

create trigger location_tr on t1 insert, update begin     if exists(select * inserted country <> 'usa')         begin             print 'you cant add user out of usa!'             rollback transaction         end     end

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
