Schema - Do you create primary key on your tables?
6/11/2019 11:01 AM by
When you specify a PRIMARY KEY constraint for a table, SQL Server enforces data uniqueness by creating a unique index for the primary key columns. This index also permits fast access to data when the primary key is used in queries.
Although, strictly speaking, the primary key is not essential you can update tables in SQL Enterprise Manager without it - we recommend all tables have a primary key (except tables that have a high volume of continuous transactions). Especially, when you have a client like Access, it would help you to avoid the problems.
Do you feel this rule needs an update?
