Below Query will help to get the requery result from concated string.
Create Table Schema
CREATE TABLE "TBL_VKYC_CRMDETAILS"
(
"ID" NUMBER(10,0) NOT NULL ENABLE,
"PRODUCTTYPE" VARCHAR2(50 BYTE) NOT NULL ENABLE,
"REFNO" VARCHAR2(50 BYTE) NOT NULL ENABLE,
"CRMCASENO" VARCHAR2(50 BYTE) NOT NULL ENABLE,
"CREATEDDATE" VARCHAR2(50 BYTE) NOT NULL ENABLE,
"SQSREFID" VARCHAR2(100 BYTE) DEFAULT NULL,
"CRMDOCRESPONSEID" VARCHAR2(100 BYTE) DEFAULT NULL,
"SQSFILENAME" VARCHAR2(2000 BYTE) DEFAULT NULL
);
CREATE SEQUENCE SEQ_TBL_VKYC_CRMDETAILS
MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 CACHE 20 NOORDER NOCYCLE ;
CREATE OR REPLACE TRIGGER TBL_VKYC_CRMDETAILS_SEQ
BEFORE INSERT ON TBL_VKYC_CRMDETAILS
FOR EACH ROW
BEGIN
SELECT SEQ_TBL_VKYC_CRMDETAILS.NEXTVAL
INTO :new.id
FROM dual;
END;
/
ALTER TRIGGER TBL_VKYC_CRMDETAILS_SEQ ENABLE;
--================
Like string is concatenated with comma seperate string/value, get the comma seperate value from relational table in rows, later get values for all rows and again convert into single column on ORACLE
Create table tblFirst(Id int, Name VARCHAR2(50), CompanyIds varchar2(50))
insert into tblFirst(id, Name, CompanyIds) values (1, 'Murli', '1')
insert into tblFirst(id, Name, CompanyIds) values (2, 'User 1', '1,2')
insert into tblFirst(id, Name, CompanyIds) values (3, 'User 2', '1,2')
insert into tblFirst(id, Name, CompanyIds) values (4, 'User 3', '1,2,3')
insert into tblFirst(id, Name, CompanyIds) values (5, 'User 0', '1,2')
select * from tblFirst
Commit
--------------------------------
Create table tblCompany(Id int, CompanyName varchar2(50))
insert into tblCompany(id, CompanyName) values (1, 'Company A');
insert into tblCompany(id, CompanyName) values (2, 'Company B');
insert into tblCompany(id, CompanyName) values (3, 'Company C');
select * from tblCompany
Commit
------------------------------
select t1.*, (select listagg(CompanyName,',') WITHIN GROUP (ORDER BY 1) --product_variant_name, product_category,product_variant_id
from tblCompany C
where C.id in
(select regexp_substr(t1.CompanyIds,'[^,]+', 1, level)
from dual
connect BY regexp_substr(t1.CompanyIds, '[^,]+', 1, level)
is not null)) "Company Names" from tblFirst t1
order by t1.id desc
Output will look like this
