I have a table I imported from Access to SQL Server, it didn't recognise that the column named ID was a primary key column, nor that it was an incrementing identity column.
How do I set 'is identity' to yes for incrementing id when rows of data already exist in the table? When I do this in the tables design using SQL Server Express 2008 r2 it says:
'Saving changes not permitted. The changes you have made require the following tables to be dropped and re-created'!! ...it's a lot of tables and a lot of data, so I need a way of doing this quickly and efficiently.
