Could anyone please tell me what will happen and what risk analysis we need to do if we want to add a column in an existing table in the database?

1) Generate new DCLGEN for the amended table if requires
2) Check for Bulk insert(From select statements)
3) Cursor declaration Fetch into variables need to be considered
