special characters in SQL Query

Dear All,

if i have this organization_name : 'O/S & COUNTRY STN. MGRS' and i want its organization_id

query:

select name, organization_id  from hr_all_organization_units where name like 'O/S & COUNTRY STN. MGRS'

it gives "Enter value for country:" because it contains special characters.

so how can i write it to take the value of the string as is.

please advise
