如何更改数据类型SQL Server 2008 R2

Question

I am trying to change a column from identity(1,1) NOT null to INT NOT NULL?

What is the SQL command to alter this table?

i already try but not success , the data still auto increment.

Answer 1

After altering your column datatype you need to set Identity insert to on for you table, like below.

SET IDENTITY_INSERT YourTableName ON

After this you should be able to insert your values on the column that was an Identity column.
