Question

Will oracle stored procedure support the use of ‘strcspn’ and ‘strncpy’ inside the procedure ?

Answer 1

they are c functions not pl/sql. to get the IP + port from the string you’ve supplied its like this anonymous block sample

(sample code assumes there’s a “-” in the string, you may want to validate this up front!)

declare
  v_str  varchar2(1000) := '4000-10.1.1.1';
  v_port pls_integer;
  v_ip   varchar2(50);
begin
  v_port := substr(v_str, 1, instr(v_str, '-')-1);
  v_ip   := substr(v_str, instr(v_str, '-') + 1);
  dbms_output.put_line(v_port);
  dbms_output.put_line(v_ip);
end;
