Split function in oracle to comma separated values with automatic sequence

Question

Need Split function which will take two parameters, string to split and delimiter to split the string and return a table with columns Id and Data.And how to call Split funct

Answer 1

Best Query For comma separated in This Query we Convert Rows To Column ...

SELECT listagg(BL_PRODUCT_DESC, ', ') within
   group(   order by BL_PRODUCT_DESC) PROD
  FROM GET_PRODUCT
--  WHERE BL_PRODUCT_DESC LIKE ('%WASH%')
  WHERE Get_Product_Type_Id = 6000000000007

If you need a function try this.
First we'll create a type:

CREATE OR REPLACE TYPE T_TABLE IS OBJECT
(
    Field1 int
    , Field2 VARCHAR(25)
);
CREATE TYPE T_TABLE_COLL IS TABLE OF T_TABLE;
/

Then we'll create the function:

CREATE OR REPLACE FUNCTION TEST_RETURN_TABLE
RETURN T_TABLE_COLL
    IS
      l_res_coll T_TABLE_COLL;
      l_index number;
    BEGIN
      l_res_coll := T_TABLE_COLL();
      FOR i IN (
        WITH TAB AS
          (SELECT '1001' ID, 'A,B,C,D,E,F' STR FROM DUAL
          UNION
          SELECT '1002' ID, 'D,E,F' STR FROM DUAL
          UNION
          SELECT '1003' ID, 'C,E,G' STR FROM DUAL
          )
        SELECT id,
          SUBSTR(STR, instr(STR, ',', 1, lvl) + 1, instr(STR, ',', 1, lvl + 1) - instr(STR, ',', 1, lvl) - 1) name
        FROM
          ( SELECT ',' || STR || ',' AS STR, id FROM TAB
          ),
          ( SELECT level AS lvl FROM dual CONNECT BY level <= 100
          )
        WHERE lvl <= LENGTH(STR) - LENGTH(REPLACE(STR, ',')) - 1
        ORDER BY ID, NAME)
      LOOP
        IF i.ID = 1001 THEN
          l_res_coll.extend;
          l_index := l_res_coll.count;
          l_res_coll(l_index):= T_TABLE(i.ID, i.name);
        END IF;
      END LOOP;
      RETURN l_res_coll;
    END;
    /

Now we can select from it:

select * from table(TEST_RETURN_TABLE()); 

Output:

SQL> select * from table(TEST_RETURN_TABLE());

    FIELD1 FIELD2
---------- -------------------------
      1001 A
      1001 B
      1001 C
      1001 D
      1001 E
      1001 F

6 rows selected.

Obviously you'd need to replace the WITH TAB AS... bit with where you would be getting your actual data from. Credit Credit
