How do I determine if a column is an identity column in MSSQL 2000?

Question

I want to do this in code, not with ALT+F1.

Answer 1

Identity is the value that is used for the very first row loaded into the table.

There is a microsoft article which can provide good knowledge about Identity:

https://docs.microsoft.com/en-us/sql/t-sql/statements/create-table-transact-sql-identity-property?view=sql-server-2017

Now, there are couple of ways for identifying which column is an identity column in a table:

• We can use sql query: select columnproperty(object_id('mytable'),'mycolumn','IsIdentity')
• sp_help tablename
