NEXT_HTTP_RESPONSE_HEADER( header-name )

LONG VARCHAR

This function is used to iterate over the HTTP response headers returning the next HTTP response header name. Calling it with NULL causes it to return the name of the first response header. Subsequent response headers are retrieved by passing the name of the previous response header to the function. This function returns NULL when called with the name of the last response header, or if it is not called from a web service.

Calling this function repeatedly returns all the response header fields exactly once, but not necessarily in the order they appear in the HTTP response.

• HTTP_RESPONSE_HEADER function [Web service]
• HTTP request header management
• Web services functions
• Web services system procedures

When used within a stored procedure that is called by an HTTP web service, the following example displays the name and values of the HTTP response headers in the database server messages window.

BEGIN
  declare header_name long varchar;
  declare header_value long varchar;
  set header_name  = NULL;
header_loop:
  LOOP
    SET header_name = NEXT_HTTP_RESPONSE_HEADER( header_name );
    IF header_name IS NULL THEN 
      LEAVE header_loop
    END IF;
    SET header_value = HTTP_RESPONSE_HEADER( header_name );
    MESSAGE 'RESPONSE HEADER: ', header_name, '=', header_value TO CONSOLE;
  END LOOP;
