Various methods of copying a table with a new
name using a select statement in SQL Server. It takes a lots of time to create new empty
table and defining all field names again. Various methods are explained below.
Creating
Table in SQL Server
create table StudentDetails
(
roll_num int,
F_Name varchar(15),
L_Name varchar(15),
City varchar(15)
)
Insert
values in above table and table will look like below image
Method
I
Select all columns into new table but this way
of copying will not copy constraints and indexes. This technique will copy all
the columns of the source table (StudentDetails) to the destination table
(StudentDetailsCopy).
Method
II
Select only the columns we want into the new
table. Suppose we want to copy roll_num, F_Name, City columns from
StudentDetails table into the StudentDetailsCopy1 table. Constraints and
indexes will not be copied.
Method
III
To copy the structure of the source table into
another new table with new name. Constraints and indexes will not be copied.
Here, 1=2 will prevent the data from being
copied from StudentDetail to the StudentDetailCopy2 table.
