Pl/sql name_in function - Sql function.

Question

Hi, I try this in sql:
Declare
h_v_1 VARCHAR2(100) := 'test_1 ';
h_v_2 VARCHAR2(100) := 'test_2 ';
h_v_3 VARCHAR2(100) := 'test_3 ';
h_v_test VARCHAR2(300) := null;
BEGIN
FOR i IN 1..3 LOOP
h_v_test := h_v_test||name_in('h_v_'||i);
END LOOP;
END;
Problem is: name_in is a pl/sql function is there a function in sql to do the same or do i have to make a work-around for it?
Greetings.

Answer 1

I want to use an equal sql function that does the same like name_in() in pl/sql. I am trying to write a sql script where i read data from a table into a variable and I want to use the data from that variable to pick up an constant variable.
something like:
DECLARE
h_rgb_black constant VARCHAR2(100) := 'r0g0b0';
h_rgb_white constant VARCHAR2(100) := 'r255Gg55b255';
h_rgb_blue constant VARCHAR2(100) := 'r0g0b255';
CURSOR c_color
IS
SELECT color_id, visual_attr
FROM dnv_colors;
-- visualt_attr is like 'VA_KL_%'
h_color VARCHAR2(100);
h_rgb_bg VARCHAR2(100);
BEGIN
FOR r_color IN c_color LOOP
h_va := substr(r_color.visual_attr, 6, length(r_color.visual_attr));
h_rgb_fg := name_in('h_rgb_'||h_va);
UPDATE dnv_colors SET background_rgb = h_rgb_bg WHERE color_id = r_color.color_id;
END LOOP;
END;
name_in gives error now.
