Lua table insert sorted inmemory code#
The following code sample requires a directory called c:\Data\. With interpreted stored procedures, these error conditions typically do not cause a failure when the stored procedure is created, but all executions will fail.

With natively compiled stored procedures, many error conditions can be detected at create time and will cause creation of the natively compiled stored procedure to fail (such as arithmetic overflow, type conversion, and some divide-by-zero conditions). One difference between interpreted (disk-based) stored procedures and natively compiled stored procedures is that an interpreted stored procedure is compiled at first execution, whereas a natively compiled stored procedure is compiled when it is created. For more information about migrating disk-based stored procedures to natively compiled stored procedures, see Migration Issues for Natively Compiled Stored Procedures. For more details about the native compilation process, see Native Compilation of Tables and Stored Procedures. Natively compiled stored procedures allow for efficient execution of the queries and business logic in the stored procedure. Natively compiled stored procedures are Transact-SQL stored procedures compiled to native code, and that access memory-optimized tables.

You can also use a traditional, interpreted Transact-SQL to access data in memory-optimized tables.Īs needed, migrate data from existing tables to memory-optimized tables.įor information on how to use SQL Server Management Studio to create memory-optimized tables, see SQL Server Management Studio Support for In-Memory OLTP. For more information, see CREATE PROCEDURE (Transact-SQL). For more information, see Statistics for Memory-Optimized Tables.Ĭreate natively compiled stored procedures to access data in memory-optimized tables. Load data into the memory-optimized table and update statistics after loading the data and before creating the compiled stored procedures. For more information, see CREATE TABLE (Transact-SQL). To enable an application to use In-Memory OLTP, you need to complete the following tasks:Ĭreate a memory-optimized data filegroup and add a container to the filegroup.Ĭreate memory-optimized tables and indexes. This topic contains a sample that introduces you to the syntax for In-Memory OLTP. Applies to: SQL Server (all supported versions)
