-- Create Memory Optimized System-Versioned Temporal Table Template
|
|
-- Use the Specify Values for Template Parameters command (Ctrl-Shift-M) to fill in the parameter values below.
|
|
--
|
|
-- This template creates a memory optimized system-versioned temporal table and indexes on the memory optimized table.
|
|
--
|
|
-- The database must have a MEMORY_OPTIMIZED_DATA filegroup before the memory optimized table can be created.
|
|
-- To learn about prerequistes for creating memory-optimized tables, take a look at "Creating a Memory-Optimized Table and a Natively Compiled Stored Procedure":
