This blog explains how to
truncate the system version enabled table (i.e. temporal table) and Stopping
System-Versioning on a System-Versioned Temporal Table
If you want to truncate the
temporal table, you will get below error message
truncate table dbo.Project
Msg 13545, Level 16, State 1, Line 21
Truncate failed on table 'dbo.Project'
because it is not a supported operation on system-versioned tables.
You want to perform any specific
DML operation on temporal table and you want to temporary disable system–versioned
table or you don’t need any version table anymore.
You can simple use SYSTEM_VERSIONING
= OFF option and history table will stop capturing the
updates
-- Disable the system version table
ALTER TABLE dbo.Project SET (SYSTEM_VERSIONING = OFF);
--Truncate data
Truncate Table dbo.Project
--Enable the system version table
ALTER TABLE dbo.Project SET ( SYSTEM_VERSIONING = ON );
