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.
