Inserting and manipulating data in object tables resulting from inheritance

Question

Dear All,
Let's say we have the following definitions:
create type t1 as object(x number) not final;
create type t2 under t1(y number);
create table t1t of t1;
create table t2t of t2;
If I want to insert a new row in t1t I can do insert into t1t values(t1(1));
How would I deal with the case of t2? I tried
insert into t2t
select z(12, select value(e).x from t1t e where e.x=12))
to no availability.
How can I run an insert in t2t without replicating the information of the parent object of t1?
Regards,
Jim

Hi Parmar18,
Regarding your description, the rows are having same pattern with tabs(CHAR(9)) as delimiter in between dates and amounts, what is the delimiter between in a date and amount pair then? I suppose that is a space(CHAR(32)), you can reference the below sample
to code to achieve your requirement.
DECLARE @Str VARCHAR(MAX)
DECLARE @T TABLE(ID INT, String VARCHAR(MAX))
INSERT INTO @T VALUES(1,'immediate due 14,289.00 04/15/15 5,213.00 05/15/15 5,213.00 06/15/15 5,213.00 07/15/15 5,213.00 08/15/15 5,213.00 09/15/15 5,213.00 10/15/15 5,213.00 11/15/15 5,210.00')
INSERT INTO @T VALUES(2,'04/15/15 5,213.00 05/15/15 5,213.00 06/15/15 5,213.00 immediate due 14,289.00 07/15/15 5,213.00 08/15/15 5,213.00 09/15/15 5,213.00 10/15/15 5,213.00 11/15/15 5,210.00')
SELECT ID,
SUBSTRING(StringLiteral,1,CHARINDEX(CHAR(32),StringLiteral)) AS DATE,
RIGHT(StringLiteral,LEN(StringLiteral)-CHARINDEX(CHAR(32),StringLiteral)) AS AMOUNT
FROM @T
CROSS APPLY
(SELECT REPLACE(StringLiteral,'immediate due',CONVERT(VARCHAR(8),GETDATE(),1)) StringLiteral FROM dbo.fnSplitDelimitedStringList(String,CHAR(9))) AS CAT
The User-Defined Function fnSplitDelimitedStringList is referenced from
here.
If you have any question, feel free to let me know.
