Syntax

public class MsSqlServerStorage : IStorage2, 
	IStorage

Public Class MsSqlServerStorage
	Implements IStorage2, IStorage

The MsSqlServerStorage type exposes the following members.

	Name	Description
	MsSqlServerStorage	Initializes a new instance of the MsSqlServerStorage class.

	Name	Description
	AcquireLock	Acquires a lock on a named resource.
	AddInSet	Adds a single string value to a set of values denoted from the given key.
	ClearAllData	Utility method. Clears all data from the storage data tables.
	CreateSchema	Utility method. Creates the data schema (tables and stored procedures) needed from the storage.
	Delete	Deletes a key with its value (string or byte array) from the storage.
	DeleteInSet	Deletes a single string value from a set of values denoted from the given key.
	DeleteMasterKey
	DeleteSet	Deletes a set of values denoted by the given key.
	Exists	Retrieves a value indicating if a single value (string or byte array) exists in the storage.
	ExistsInSet	Retrieves a value indicating if a set of values exists in the storage.
	GetAllMembersInSet	Retrieves all members in a set of string values.
	GetBytes	Retrieves a byte array value stored under particular key.
	GetCountInSet	Retrieves the count of the values in a set value stored in the storage.
	GetString	Retrieves a string value stored under particular key.
	SetBytes	Stores a byte array value under particular key.
	SetString	Stores a string value under particular key.

Remarks

MsSqlServerStorage connects to SQL server using the .NET Framework Data Provider for SQL Server (System.Data.SqlClient Namespace).

The storage needs a host database with specific tables and stored procedures which may be created in dedicated or shared database. The necessary SQL objects may be created using the DatabaseCacheConfigurator tool (located under the Telerik Reporting installation folder / Tools) or manually executing the follow DDL script. It adds all needed objects to an existing MS SQL database (execute in the context of existing database).
