Replacement |
|---|---|---|
Local cubes |
InsertInto connection string property |
Original connection string syntax for populating local cubes is replaced by the Create Global Cube statement. For more information, see CREATE GLOBAL CUBE Statement (MDX). |

CreateCube connection string property |
Original connection string syntax for populating local cubes is replaced by the Create Global Cube statement. For more information, see CREATE GLOBAL CUBE Statement (MDX). |
Data Mining |
SQL Server 2000 PMML |
The SQL Server 2000 PMML feature produced a form of PMML that had proprietary extensions to support unique features provided by Data Mining algorithms that were not available in the PMML specification. In SQL Server 2005, Analysis Services updated the PMML feature to the newer PMML 2.1 standard. As a result, the proprietary extensions added in SQL Server 2000 are no longer needed, although they are still supported in this release. |
MDX Statement |
Create Action statement |
This statement is included for backwards compatibility. It is replaced by the Action object. For more information about how to create actions in recent versions of Analysis Services, see Actions (Analysis Services - Multidimensional Data). |
MDX Statement |
Non_empty_behavior proeprty |
Avoid setting this property when creating a calculated member. Setting it incorrectly increases the chances of returning invalid results. Furthermore, the property is no longer as useful as it once was. Engine optimizations over the past several releases have improved operations over sparse data sets, making this property less relevant. |
Features Not Supported in a Future Version of SQL Server
The following Analysis Services features are supported in the next version of SQL Server, but will be removed in a later version. The specific version of SQL Server has not been determined.

MDX Function |
CalculationPassValue function |
None. The OLAP engine manages the calculation pass. This function is no longer needed. |
MDX Function |

None. The OLAP engine manages the calculation pass. This function is no longer needed. |
Multidimensional Expressions (MDX) |
NON_EMPTY_BEHAVIOR query optimizer hint was turned on by default. |
The NON_EMPTY_BEHAVIOR query optimizer hint will be turned off by default in a future release. It is an MDX optimization hint that can produce incorrect results when it is not used correctly. |
MDX |
Non_Empty_Behavior property |
None. When creating a calculated member, setting this property incorrectly increases the likelihood of returning invalid results. Recent optimizations to the OLAP engine have improved operations over sparse data sets, making this property less relevant. |
Other |
CELL_EVALUATION_LIST intrinsic cell property |
Originally provided a list of evaluated formulas that apply to a cell. It is blank in this release of Analysis Services. Solve order is now specified in MDX script. For more information, see Understanding Pass Order and Solve Order (MDX) |
Objects |
COM assemblies |
COM assemblies can pose a security risk. Support for COM assemblies will be removed in a future release. |
