This is one of the tricky interviews. In one interview, the interviewer asks this question to my friend. He asked to write the insert script to insert a record a record into a table which has only one identity column.
Identity column: Identity column of a table is a column whose value increases automatically. The value in an identity column is created by the server. A user generally cannot insert a value into an identity column. An identity column can be used to uniquely identify the rows in the table.
See the example
I am creating a table with one identity column.
CREATE TABLE TestTable
( Id int identity(1,1) )
|
Table is created successfully.
Now I am trying to insert a record into this table.
For inserting the record we need to use “DEFAULT VALUES”
Let’s see the example.
See the result.
