table, even if the other columns allow the appropriate duplicates to occur. This type of primary key column is commonly referred to as a pseudo-primary key or surrogate key . Most databases provide an underlying scenario that is unrelated to the current transaction to ensure that a globally unique integer is generated every time as a pseudo-primary key, even if the client is initiating concurrent operations at this time. The role of the primary key exists: 1. Ensure that the data in one table d
