# ASP.NET Session State with SQL Server 2016
We are excited to offer two new SQL Server scripts (with and without retry-logic) to be used with the ASP.NET Session State provider!
The scripts take advantage of memory optimized tables and natively compiled stored procedures to create the necessary database objects that the ASP.NET session state provider requires when SQL Server is used as a storage option for session data. These scripts are based on work from early adopters that modified their SQL Server objects to take advantage of In-Memory OLTP for ASP.NET session state, with great success. To learn more, read the bwin.party case study [Gaming site can scale to 250,000 requests per second and improve player experience](https://www.microsoft.com/danmark/cases/Microsoft-SQL-Server-2014/bwin.party/Gaming-Site-Can-Scale-to-250-000-Requests-Per-Second-and-Improve-Player-Experience/710000003117).
**This is the recommended way to implement ASP.NET session state with SQL Server 2016**.

## About this sample
1. **Applies to:** SQL Server 2016 (or higher) Enterprise / Developer / Evaluation Edition, Azure SQL Database (Premium)
2. **Key features:**
- ASP.NET Session State Provider
- Memory Optimized Tables
- Natively Compiled Stored Procedures
4. **Programming Language:** T-SQL
5. **Authors:** Perry Skountrianos [perrysk-msft]
<a name=before-you-begin></a>
## Before you begin
**Software prerequisites:**
1. SQL Server 2016 (or higher) Enterprise / Developer / Evaluation Edition or Azure SQL Database (Premium)
2. .NET Framework 2.0 or higher
<a name=install-scripts></a>
## Install Scripts
There are two versions of the SQL Server script (with retry logic and without):
- [aspstate_sql2016 (no retry logic)](https://github.com/Microsoft/sql-server-samples/blob/master/samples/applications/ASP.NET%20Session%20State/aspstate_sql2016_no_retry.sql)
- [aspstate_sql2016 (with retry logic)](https://github.com/Microsoft/sql-server-samples/blob/master/samples/applications/ASP.NET%20Session%20State/aspstate_sql2016_with_retry.sql)
Based on your workload characteristics and the way your application handles session state you have to decide if retry logic is needed or not. [This](https://msdn.microsoft.com/en-us/library/mt668435.aspx) article explains the logic used to detect conflict and implement retry logic in the script. Currently, the two memory-optimized tables: **dbo.ASPStateTempApplications** and **dbo.ASPStateTempSessions** in both of the scripts are created with **DURABILITY = SCHEMA_ONLY** meaning that in a case of a SQL Server restart or a reconfiguration occurs in an Azure SQL Database, the table schema persists, but data in the table is lost. If durability of both schema and data is required tthe script needs to be altered and the two tables above need to be created with: **DURABILITY=SCHEMA\_AND\_DATA**.[This](https://msdn.microsoft.com/en-us/library/dn553122.aspx) article explains the two durability options for memory-optimized tables
Note: Although both of these scripts have been tested, we always recommend executing your own testing and validation to understand how these scripts behave in your specific environment.
Follow the steps below to configure SQL Server 2016 In-Memory OLTP to store ASP.NET Session State:
1. Follow [this](https://support.microsoft.com/en-us/kb/317604) link to configure SQL Server to Store ASP.NET Session State
2. Open the script in SQL Server Management Studio ([Download Link](https://support.microsoft.com/en-us/kb/317604))
3. Connect to the SQL Server that you want to use.
4. Execute (F5)
The script should execute with no errors and should create the **ASPState** database with the following objects:
Tables:
-
- dbo.ASPStateTempApplications
- dbo.ASPStateTempSessions
Stored Procedures
-
- dbo.TempGetStateItemExclusive3
- dbo.TempInsertStateItemShort
- dbo.TempUpdateStateItemLong
- dbo.TempUpdateStateItemLongNullShort
- dbo.TempUpdateStateItemShort
- dbo.CreateTempTables
- dbo.DeleteExpiredSessions
- dbo.GetHashCode
- dbo.GetMajorVersion
- dbo.TempGetAppID
- dbo.TempGetStateItem
- dbo.TempGetStateItem2
- dbo.TempGetStateItem3
- dbo.TempGetStateItemExclusive
- dbo.TempGetStateItemExclusive2
- dbo.TempGetVersion
- dbo.TempInsertStateItemLong
- dbo.TempInsertUninitializedItem
- dbo.TempReleaseStateItemExclusive
- dbo.TempRemoveStateItem
- dbo.TempResetTimeout
- dbo.TempUpdateStateItemShortNullLong

## About this sample
<!-- Delete the ones that don't apply -->
1. **Applies to:** SQL Server 2016 (or higher), Azure SQL Database
1. **Key features:** Dynamic Data Masking
1. **Workload:** OLTP
1. **Programming Language:** T-SQL
1. **Author:** Rick Davis
1. **Update history:** 20 October 2016 - initial revision
<a name=before-you-begin></a>
## Before you begin
To run this sample, you need the following prerequisites.
**Software prerequisites:**
<!-- Examples -->
1. SQL Server 2016 (or higher) or Azure SQL Database.
- With SQL Server, make sure SQL authentication is enabled.
2. SQL Server Management Studio
3. The WideWorldImporters database.
<a name=run-this-sample></a>
## Running the sample
1. Open the script DemonstrateDDM.sql in Management Studio and connect to the WideWorldImporters database.
2. Follow the instructions in the script.
## Sample details
The WideWorldImporters sample database leverages Dynamic Data Masking to mask sensitive banking data in the table 'Purchasing.Suppliers'.
When connecting to the database and running a query using a privileged user such as the database owner, you will see the sensitive data in the clear.
The user 'GreatLakesSales' is an example unprivileged user, and will only see the masked values.

SQL Server VSS allows ISVs to develop backup solutions using APIs exposed by VSS framework. One such API method which is commonly used while performing differential backup using SQL VSS is IVssComponent::GetPartialFile. While performing differential backup, IVssComponent::GetPartialFile is used iteratively to obtain the range of changed differential bytes for backup which changed since last full backup.
The output for GetPartialFile provides the file path, file name and pbstrRange which is a pointer to 64KB string buffer containing the comma-separated list of the form offset1:length1, offset2:length2, where each offset and length is a 64-bit integer specifying a file offset in bytes and length of the range in bytes, respectively.
The output for *GetPartialFile* provides the file path, file name and pbstrRange which is a pointer to 64KB string buffer containing the comma-separated list of the form offset1:length1, offset2:length2, where each offset and length is a 64-bit integer specifying a file offset in bytes and length of the range in bytes, respectively.
If the changed pages within a partial file is large enough to fall outside the tracking range limit of the 64 bit string buffer, pbstrRange returns the filename containing those ranges instead of the range and offset within the current partial file.
The ISV Backup code should be able to handle both the output for pbstrRange viz offset/length range string for backup range within the current file or filename containing the backup range if the range falls outside the current file.
