How can we add a column to a table without altering the same?..

Answer / shoaib

you can add new column by using CAST keyword.

Eg:

Suppose your existing table say #EMP contain the following
Columns:

empid,
empname,
empaddr

you want to add empsal columns.

Query:
select
empid,
empname,
empaddr,
(null as decimal(18,2))empsal
from #EMP
into #EMP1;
