Create Customer table as below:

CustomerName varchar(100),
CustomerLocation varchar(50)
)
Execute above statements. Customer table will be created.
Now insert customer data into Customer table as shown below:
insert into Customer(CustomerID, CustomerName, CustomerLocation)
values(1, 'Microsoft', 'Hyderabad')
Execute above statements then you will get following error message.
"Cannot insert explicit value for identity column in table 'Customer' when IDENTITY_INSERT is set to OFF."
In order to insert CustomerID into Customer table we need to set IDENTITY_INSERT to ON.
Solution:
1) Set IDENTITY_INSERT to ON.
2) Insert customers data into Customer table.
3) Set IDENTITY_INSERT to OFF.
Set IDENTITY_INSERT Customer ON;
insert into Customer(CustomerID, CustomerName, CustomerLocation)
values(1, 'Microsoft', 'Hyderabad')
insert into Customer(CustomerID, CustomerName, CustomerLocation)
values(2, 'Oracle', 'Hyderabad')
Set IDENTITY_INSERT Customer OFF;
Execute above statements. Now data will be inserted.
