SQL Server Management Objects Support for In-Memory OLTP

This topic describes items in SQL Server Management Objects (SMO) that support In-Memory OLTP.

SMO types and members

The following types and members are in the namespace Microsoft.SqlServer.Management.Smo, and they support In-Memory OLTP:

C# code example

Assemblies referenced by the compiled code example

  • Microsoft.SqlServer.ConnectionInfo.dll
  • Microsoft.SqlServer.Management.Sdk.Sfc.dll
  • Microsoft.SqlServer.Smo.dll
  • Microsoft.SqlServer.SqlEnum.dll

Actions taken in the code example

  1. Create a database with memory-optimized filegroup and memory-optimized file.
  2. Create a durable memory-optimized table with a primary key, nonclustered index, and a nonclustered hash index.
  3. Create columns and indexes.
  4. Create a user-defined memory-optimized table type.
  5. Create a natively compiled stored procedure.
