oracle - Filter option using regular expression -


i have requirement filter names in table.

example table name :- student

columns :- name, class.

the date

name ----class

highspeed ---c

highspeed11 ---c1

highspeed22 ---c2

normal-------------n

normal1-------------n1

normal2-------------n2

like have data srq, pwe ...

my requirement need remove data using name...

select distinct name student upper (name) 'srp%' or upper (name) 'highspeed%' or upper (name) 'srq%' or upper (name) 'pwe%' or upper (name) 'spinterface%' or upper (name) 'srm%' instead of using or condition, please let me know other option... ?

thanks in advance.

i'm not oracle user, quick through docs indicates oracle supports posix extended regular expressions (ere). regular expression matches names in query be:

^(srp|highspeed|srq|pwe|spinterface|srm)

it looks oracle supplies regexp_like function, query re-written using regular expression as:

select distinct name student regexp_like(upper(name), '^(srp|highspeed|srq|pwe|spinterface|srm)');

i'm afraid don't have access oracle test that's regular expression like.

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 .
