Lihat Cara membagi string yang dipisahkan koma menjadi baris
1. Pendekatan REGEXP_SUBSTR
SQL> WITH DATA AS(
2 SELECT 'ac_Abc.88,ac_Abc.99,ac_Abc.77' str FROM dual)
3 SELECT regexp_substr(str,'[^,]+',1,level) str
4 FROM DATA
5 CONNECT BY regexp_substr(str, '[^,]+', 1, level) IS NOT NULL
6 /
STR
-----------------------------
ac_Abc.88
ac_Abc.99
ac_Abc.77
SQL>
2. Pendekatan XML
SQL> SELECT EXTRACT (VALUE (d), '//row/text()').getstringval () str
2 FROM
3 (SELECT XMLTYPE ( '<rows><row>'
4 || REPLACE ('ac_Abc.88,ac_Abc.99,ac_Abc.77', ',', '</row><row>')
5 || '</row></rows>' ) AS xmlval
6 FROM DUAL
7 ) x,
8 TABLE (XMLSEQUENCE (EXTRACT (x.xmlval, '/rows/row'))) d
9 /
STR
--------------------
ac_Abc.88
ac_Abc.99
ac_Abc.77
3. Fungsi tabel
SQL> CREATE TYPE test_type
2 AS
3 TABLE OF VARCHAR2(100)
4 /
Type created.
SQL>
SQL> CREATE OR REPLACE
2 FUNCTION comma_to_table(
3 p_list IN VARCHAR2)
4 RETURN test_type
5 AS
6 l_string VARCHAR2(32767) := p_list || ',';
7 l_comma_index PLS_INTEGER;
8 l_index PLS_INTEGER := 1;
9 l_tab test_type := test_type();
10 BEGIN
11 LOOP
12 l_comma_index := INSTR(l_string, ',', l_index);
13 EXIT
14 WHEN l_comma_index = 0;
15 l_tab.EXTEND;
16 l_tab(l_tab.COUNT) := SUBSTR(l_string, l_index, l_comma_index - l_index);
17 l_index := l_comma_index + 1;
18 END LOOP;
19 RETURN l_tab;
20 END comma_to_table;
21 /
Function created.
SQL> sho err
No errors.
SQL>
SQL> SELECT * FROM TABLE(comma_to_table('ac_Abc.88,ac_Abc.99,ac_Abc.77'))

4. Fungsi Pipeline
SQL> CREATE OR REPLACE
2 FUNCTION comma_to_table(
3 p_list IN VARCHAR2)
4 RETURN test_type PIPELINED
5 AS
6 l_string LONG := p_list || ',';
7 l_comma_index PLS_INTEGER;
8 l_index PLS_INTEGER := 1;
9 BEGIN
10 LOOP

12 EXIT
13 WHEN l_comma_index = 0;
14 PIPE ROW ( SUBSTR(l_string, l_index, l_comma_index - l_index) );
15 l_index := l_comma_index + 1;
16 END LOOP;
17 RETURN;
18 END comma_to_table;
19 /
Function created.
