SSRS multi-value parameter using a stored procedure

Question

I am working on a SSRS report that uses a stored procedure containing a few parameters. I am having problems with two of the parameters because I want to have the option of

Answer 1

Finally I was able to get a simple solution for this problem. Below I have provided all (3) steps that I followed.

I hope you guys will like it :)

Step 1 - I have created a Global Temp Table with one column.

CREATE GLOBAL TEMPORARY TABLE TEMP_PARAM_TABLE(
  COL_NAME  VARCHAR2(255 BYTE)
) ON COMMIT PRESERVE ROWS NOCACHE;

Step 2 - In the split Procedure, I didn't use any array or datatable, I have directly loaded the split values into my global temp table.

CREATE OR REPLACE PROCEDURE split_param(p_string IN VARCHAR2 ,p_separator IN VARCHAR2
)
IS
   v_string VARCHAR2(4000);
   v_initial_pos NUMBER(9) := 1;
   v_position NUMBER(9) := 1;
BEGIN
   v_string := p_string || p_separator;

   delete from temp_param_policy;

   LOOP
      v_position :=
                  INSTR(v_string, p_separator, v_initial_pos, 1);
      EXIT WHEN(NVL(v_position, 0) = 0);

      INSERT INTO temp_param_table
           VALUES (SUBSTR(v_string, v_initial_pos
                         , v_position - v_initial_pos));

      v_initial_pos := v_position + 1;
   END LOOP;
commit;

END split_param;

Step 3 - In the SSRS dataset parameters, I have used

=Join(Parameters!A_COUNTRY.Value, ",")

Step 4: In the start of your stored procedure executes the Procedure

Exec split_param(A_Country, ‘,’);

Step 5: In your stored procedure sql use the condition like below.

Where country_name in (select * from TEMP_PARAM_TABLE)
