When a new row is inserted, the system will assign the Period Start time column with the current transaction start time-based on the system clock, and assign the Period End time column with the maximum datetime2 value equal to, and the row will be opened.

If you try to delete any row from the history table, you will get the (Cannot delete rows from a temporal history table ‘’) error, as it is only managed by the system. Take into consideration that no changes can be performed on the history table’s data. Specifying the history table name while creating the Temporal table will allow the system to create the history table with the default system configuration, with the ability to create your own history table and provide its name in the Temporal table creation statement. If you don’t specify the history table name as a parameter in the SYSTEM_VERSIONING clause, it will be named with the naming pattern MSSQL_TemporalHistoryFor_.

When you create a Temporal table, the History table will be created automatically. The main Temporal table will keep only the current version of the table rows, but it will be linked automatically to another table with the same exact schema, in which the previous versions of the modified rows will be stored automatically, this table is called a History table. Using a Temporal Table, you will be able to query the recent state of the row as usual, in addition to the ability to query the full history of that row, which is fully managed by the SQL Server Engine, as you can’t define the rows validity period explicitly.Įach System-Versioned Temporal Table should contain two datetime period columns that are explicitly defined in the table the Period Start column that will be used by the system to store the start time of the row, and the Period End column in which the system will store the end time of the row. In earlier SQL Server versions, user tables would enable you to hold only the most recent copy of the row, without being able to query the value before the UPDATE or DELETE operations. This new table type is called a System-Versioned Temporal Table. SQL Server 2016 introduces a new type of table that is designed to keep the full history of data changes, where row validity is managed by the system.
