Hi

You can get expected by modify the Table Schema by adding new Column for EmpCode like below

create  table tblEmpCodeTest (ID bigint identity(1 ,1),
EmpCode as 'CG'+Replicate('0', 3 - LEN(ID))+ cast(ID as varchar)  persisted not null primary key ,
FirstName varchar(10))

Note : MS SQL Server DB Query

Use IDENTITY (Property)[^] for auto increment.

Take a look at this article Auto generate auto incremented unique alphanumeric id or number in sql server[^] This article refer exactly same things you are looking for.
