How to get a data between vertical bar using PL/SQL - sql

Question

Table DATA:
id text
1 CLARE|FEMALE|PRESIDENT
2 SCARLET|FEMALE|MANAGER
3 FRANK|MALE|ANALYST
...
What I need to do is to get all data between vertical bar and put it in my variables(for insert to another table),
here what i tried :
DECLARE
v_NAME varchar2(100);
v_GENDER nvarchar2(100);
v_POSITION nvarchar2(100);
CURSOR c1
IS
SELECT *
FROM DATA
ORDER BY id;
BEGIN
FOR x IN c1 LOOP
v_NAME := REGEXP_SUBSTR(x.TEXT_NOTE, '[^|]+', 1, 1);
v_GENDER := REGEXP_SUBSTR(x.TEXT_NOTE, '[^|]+', 1, 2);
v_POSITION := REGEXP_SUBSTR(x.TEXT_NOTE, '[^|]+', 1, 3);
DBMS_OUTPUT.PUT_LINE(v_NAME ,v_GENDER ,v_POSITION); --test
END LOOP;
END;
Obviously I'm not doing this right as it doesn't work. Can somebody suggest a solution?
Thanks!

Answer 1

I think, there are two points to fix in your attempt :
In your LOOP you are referring to column "x.TEXT_NOTE" whereas it should be column "TEXT" from your table DATA.
You need to change that output line DBMS_OUTPUT.PUT_LINE(v_NAME ,v_GENDER ,v_POSITION) by DBMS_OUTPUT.PUT_LINE(v_NAME||', '||v_GENDER||', '||v_POSITION)
CREATE TABLE DATA_TO_SPLIT (id, text) as (
select 1, 'CLARE|FEMALE|PRESIDENT' from dual union all
select 2, 'SCARLET|FEMALE|MANAGER' from dual union all
select 3, 'FRANK|MALE|ANALYST' from dual
)
;
DECLARE
v_NAME varchar2(100);
v_GENDER nvarchar2(100);
v_POSITION nvarchar2(100);
CURSOR c1
IS
SELECT *
FROM DATA_TO_SPLIT
ORDER BY id;
BEGIN
FOR x IN c1 LOOP
v_NAME := REGEXP_SUBSTR(x.TEXT, '[^|]+', 1, 1);
v_GENDER := REGEXP_SUBSTR(x.TEXT, '[^|]+', 1, 2);
v_POSITION := REGEXP_SUBSTR(x.TEXT, '[^|]+', 1, 3);
DBMS_OUTPUT.PUT_LINE(v_NAME||', '||v_GENDER||', '||v_POSITION); --test
END LOOP;
END;

Answer 2

The string_split function should work.
SELECT * FROM STRING_SPLIT('CLARE|FEMALE|PRESIDENT', '|')

Answer 3

Indeed no problem seems with the current code except
the typo which needs column name conversion from text_note to
text
and adding an Insert statement for a presumed table (namely
data2) is missing
Btw, current DBMS_OUTPUT.PUT_LINEs syntax is wrong
So, use the following code :
DECLARE
v_name VARCHAR2(100);
v_gender NVARCHAR2(100);
v_position NVARCHAR2(100);
CURSOR c1 IS
SELECT *
FROM data
ORDER BY id;
BEGIN
FOR x IN c1
LOOP
v_name := TRIM(REGEXP_SUBSTR(x.text, '[^|]+', 1, 1));
v_gender := TRIM(REGEXP_SUBSTR(x.text, '[^|]+', 1, 2));
v_position := TRIM(REGEXP_SUBSTR(x.text, '[^|]+', 1, 3));
DBMS_OUTPUT.PUT_LINE(v_name||' - '||v_gender||' - '||v_position);
INSERT INTO data2
VALUES(v_name,v_gender,v_position);
END LOOP;
COMMIT;
END;
/
where TRIM() function stands for removing potential leading and trailing whitespaces
