Problem with execute immediate code

Question

I have the following anonymous block:
declare
v_id_char varchar2(50) := '2072018827821663';
trace_flg number := 0;
v_exe_imm varchar2(500) := 'univdb.EML_CAMPUS_200605(v_id_char, trace_flg)';
v_exe_imm2 varchar2(500) := 'univdb.EML_CAMPUS_200605(:v_id_char, :trace_flg)';
begin
--1) execute immediate v_exe_imm;
--2) execute immediate v_exe_imm2 using v_id_char, trace_flg);
univdb.EML_CAMPUS_200605(v_id_char, trace_flg);
end;
The compiled procedure that is getting called is defined like this:
CREATE OR REPLACE PROCEDURE univdb.eml_campus_200605(
hist_str IN VARCHAR2,
trace_flg IN NUMBER := 0) IS ...
As you might expect, when I execute the block without execute immediate it works.
But either of the execute immediate statements results in ORA-00900: invalid SQL statment.
I want to use execute immediate because the procedure that gets called will need to be dynamic.
Help appreciated,

Answer 1

For me, thats crude if you have a procedure thats
getting created dynamically.
anyway, you could try a
execute immediate ' begin ' || your_funny_proc || '
end;';But for sure the whole stuff is very error prone.Actually, the procedure itself isn't getting built dynamically, only which procedure to call. It's really quite clever in my opinion.
Anyway, I tried you suggestion:
declare
v_id_char varchar2(50) := '2072018827821663';
trace_flg number := 0;
v_exe_imm varchar2(500) := 'univdb.EML_CAMPUS_200605(v_id_char, trace_flg)';
v_exe_imm2 varchar2(500) := 'univdb.EML_CAMPUS_200605(:v_id_char, :trace_flg)';
begin
execute immediate 'BEGIN ' || v_exe_imm || '; END;';
--execute immediate v_exe_imm2 using v_id_char, trace_flg);
--univdb.EML_CAMPUS_200605(v_id_char, trace_flg);
end;
and got
ORA-06550: line 1, column 32:
PLS-00201: identifier 'V_ID_CHAR' must be declared
Did I misunderstand what you were trying for?
