Microsoft.SqlServer.Server Namespace

The Microsoft.SqlServer.Server namespace contains classes, interfaces, and enumerations that are specific to the integration of the Microsoft .NET Framework common language runtime (CLR) into Microsoft SQL Server, and the SQL Server database engine process execution environment.

Using the attribute classes in the Microsoft.SqlServer.Server namespace, you can create stored procedures, triggers, user-defined types, user-defined functions (both scalar and table-valued), and user-defined aggregate functions in any supported .NET Framework language. You can also register them in SQL Server.

Query the SqlContext class to determine whether the currently executing code is running in the SQL Server database engine process. This also provides the caller's context when a user calls a managed stored procedure or function on the server, or when a user's action fires a managed code trigger.

The SqlContext class provides a SqlPipe object, through which results are returned to the client from a stored procedure, a SqlTriggerContext object, which provides information about the operation that caused a trigger to be fired, and a WindowsIdentity object, which can be used to determine the identity of the calling client when the client used integrated security for authentication.

For more information about SQL Server CLR integration and the APIs in the Microsoft.SqlServer.Server namespace, see SQL Server Books Online.

  Class Description
Public class InvalidUdtException Thrown when SQL Server or the ADO.NET System.Data.SqlClient provider detects an invalid user-defined type (UDT).
Public class SqlContext Represents an abstraction of the caller's context, which provides access to the SqlPipe, SqlTriggerContext, and WindowsIdentity objects. This class cannot be inherited.
Public class SqlDataRecord Represents a single row of data and its metadata. This class cannot be inherited.
Public class SqlFacetAttribute Annotates the returned result of a user-defined type (UDT) with additional information that can be used in Transact-SQL.
Public class SqlFunctionAttribute Used to mark a method definition of a user-defined aggregate as a function in SQL Server. The properties on the attribute reflect the physical characteristics used when the type is registered with SQL Server.
Public class SqlMetaData Specifies and retrieves metadata information from parameters and columns of SqlDataRecord objects. This class cannot be inherited.
Public class SqlMethodAttribute Indicates the determinism and data access properties of a method or property on a user-defined type (UDT). The properties on the attribute reflect the physical characteristics that are used when the type is registered with SQL Server.
Public class SqlPipe Allows managed stored procedures running in-process on a SQL Server database to return results back to the caller. This class cannot be inherited.
Public class SqlProcedureAttribute Used to mark a method definition in an assembly as a stored procedure. The properties on the attribute reflect the physical characteristics used when the type is registered with SQL Server. This class cannot be inherited.
Public class SqlTriggerAttribute Used to mark a method definition in an assembly as a trigger in SQL Server. The properties on the attribute reflect the physical attributes used when the type is registered with SQL Server. This class cannot be inherited.
Public class SqlTriggerContext Provides contextual information about the trigger that was fired.
Public class SqlUserDefinedAggregateAttribute Indicates that the type should be registered as a user-defined aggregate. The properties on the attribute reflect the physical attributes used when the type is registered with SQL Server. This class cannot be inherited.
Public class SqlUserDefinedTypeAttribute Used to mark a type definition in an assembly as a user-defined type (UDT) in SQL Server. The properties on the attribute reflect the physical characteristics used when the type is registered with SQL Server. This class cannot be inherited.
  Interface Description
Public interface IBinarySerialize Provides custom implementation for user-defined type (UDT) and user-defined aggregate serialization and deserialization.
  Enumeration Description
Public enumeration DataAccessKind Describes the type of access to user data for a user-defined method or function.
Public enumeration Format Used by SqlUserDefinedTypeAttribute and SqlUserDefinedAggregateAttribute to indicate the serialization format of a user-defined type (UDT) or aggregate.
Public enumeration SystemDataAccessKind Describes the type of access to system data for a user-defined method or function.
Public enumeration TriggerAction The TriggerAction enumeration is used by the SqlTriggerContext class to indicate what action fired the trigger.
