How do I
auto increment the
primary key in a
SQL Server database table, I’ve had a look through the forum but can’t see how.
I’ve looked the the properties but can’t see an option, I have seen an answer where you go to the
Identity specification property and set it to yes and set the
Identity increment to 1, but that section is grayed out and I can’t change the no to yes.
There must be a simple way to do this but I can’t find it.
Make sure that the Key column’s datatype is
int and then setting identity manually, as image shows
Or just run this code
-- ID is the name of the [to be] identity column ALTER TABLE [yourTable] DROP COLUMN ID ALTER TABLE [yourTable] ADD ID INT IDENTITY(1,1)
the code will run, if
ID is not the only column in the table
