select left(patientName,3)+repalce(dob,'-','')+'01' from table1

'01' - what if you have more then 99 rows?
how do you link this two table?
i think you must have some primary key on first table and set it as foreign key in table2.

for example
create table table1 (idPN int, patientName varchar(150), DOB varchar(20), Age int, Sex varchar(1)
constraint pk_table1_idPN PRIMARY KEY(idPN))

create table table2(idPN int, regno varchar(50)
FOREIGN KEY (idPN) REFERENCES table1(idPN))

think about that

In order to help we will need a few things:

1. Sample DDL in the form of CREATE TABLE statements
2. Sample data in the form of INSERT INTO statements
3. Expected results based on the sample data

Please take a few minutes and read the first article in my signature for best practices when posting questions.

I would HIGHLY recommend NOT doing this. You are going to regret combining multiple datapoints into a single column at some point. Shoving multiple pieces of data into a single column violates 1NF. Why make things harder on yourself like this?
