Find and replace with AWK command

I have a file called sso_med.txt like

197: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160'); 
198: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',16,current_date, '502264160', current_date, '502264160'); 
199: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502689031',15,current_date, '502264160', current_date, '502264160');

But I want to make it like

insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160'); 
insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',16,current_date, '502264160', current_date, '502264160'); 
insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502689031',15,current_date, '502264160', current_date, '502264160');

I am trying the awk command

awk '{gsub(/^\d+:\s/,""); print}' sso_med.txt

But its not working.Any idea what I am doing wrong in Regex

To avoid removing similar patterns elsewhere in the string, use sub, which just replaces the first instance of the pattern:

# explanation of regex: "^"=line starts with pattern, "[0-9]+"=multiple numbers, ": "=colon and single space
awk '{sub(/^[0-9]+: /, "", $0); print $0}'

Example:

$ echo '197: insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values ('502683504',15,current_date, '502264160', current_date, '502264160');' | awk '{sub(/^[0-9]+: /, "", $0); print $0}'

Result:

insert into brs.user_components (user_name, component_id, created_date, created_by, last_updated_date,last_updated_by) values (502683504,15,current_date, 502264160, current_date, 502264160);
