Oracle – Insert Comma separated string values into Table

This is a small demonstartion of how to insert the values of a comma separated string to a table as different rows. This is not something new, Tom Kyte has already demonstrated it lot of times in AskTom. However, I just want to keep it simple, just to insert values of a comma separated string into a table.

Let’s see the demo :

SQL> SET SERVEROUTPUT ON;
SQL> CREATE TABLE TEST (COL1 VARCHAR2(10))
  2  /

Table created.

SQL> DECLARE
  2    L_INPUT VARCHAR2(4000) := 'THIS,IS,A,COMMA,SEPARATED,STRING';
  3    L_COUNT BINARY_INTEGER;
  4    L_ARRAY DBMS_UTILITY.LNAME_ARRAY;
  5  BEGIN
  6    DBMS_UTILITY.COMMA_TO_TABLE(LIST => REGEXP_REPLACE(L_INPUT, '(^|,)', '\1x'), TABLEN => L_COUNT, TAB => L_ARRAY);
  7    DBMS_OUTPUT.PUT_LINE(L_COUNT);
  8    FOR I IN 1 .. L_COUNT
  9    LOOP
 10      DBMS_OUTPUT.PUT_LINE('Element ' || TO_CHAR(I) || ' of array contains: ' || SUBSTR(L_ARRAY(I), 2));
 11      INSERT INTO TEST VALUES
 12        (SUBSTR(L_ARRAY(I), 2)
 13        );
 14      COMMIT;
 15    END LOOP;
 16  END;
 17  /
6
Element 1 of array contains: THIS
Element 2 of array contains: IS
Element 3 of array contains: A
Element 4 of array contains: COMMA
Element 5 of array contains: SEPARATED
Element 6 of array contains: STRING

PL/SQL procedure successfully completed.

SQL>  SELECT * FROM TEST
  2  /

COL1
----------
THIS
IS
A
COMMA
SEPARATED
STRING

6 rows selected.

Hope it helps!
