主要参考：动态分区
一、前提准备：
1、一个日期存储过程，注意代码可以得到一个月中的最后一天，最终生成时间维度。

2、一个事实表：
3、构建好的Cube，并且无分区（有分区也无妨，这里只是排除干扰，容易理解）：
4、准备SSIS参数：
二、利用SSIS动态构建分区
最终效果
2.1 、执行SQL任务
SQLStatement代码：
SELECT 'DrugDW' AS DataSoureID,--数据源
'Drug DW' AS CubeName,--分区来自哪一个cube
'Drug DW' AS CubeID,
'Fact OP Fee Detail' AS MeasureGroup,--指定是一个度量值组
'Fact OP Fee Detail' AS MeasureGroupID,
'Fact OP Fee Detail ' + Cast(MonthInfo.YearMonth AS VARCHAR(6)) AS Partition,--分区名称=度量值组名称+年月
'SELECT * FROM [dbo].[Fact_OPFeeDetail] where_clause' AS SQL,--要进行分区的SQL
cast(MinDateKey as varchar(8)) as MinDateKey,--最小datekey
cast(MaxDateKey as varchar(8)) as MaxDateKey--最大datekey
FROM (
SELECT t1.YearMonth,
(SELECT Min(datekey) FROM dim_date t2 WHERE CONVERT(VARCHAR(6), t2.Date, 112) = t1.YearMonth) AS MinDateKey,
(SELECT Max(datekey) FROM dim_date t2 WHERE CONVERT(VARCHAR(6), t2.Date, 112) = t1.YearMonth) AS MaxDateKey
FROM
(SELECT DISTINCT CONVERT(VARCHAR(6), Date, 112) AS YearMonth FROM dim_date) AS t1
)MonthInfo
WHERE EXISTS(SELECT * FROM [dbo].[Fact_OPFeeDetail] WHERE [VisitDateID] BETWEEN MonthInfo.MinDateKey AND MonthInfo.MaxDateKey)
SQLStatement执行结果：
设置结果集：
2.2、Foreach 循环容器便利结果集
2.3、编写脚本任务，处理每次的遍历结果：
2.4、 点击“编辑脚本”： 引用：Analysis Management Obejcts包
脚本代码(在SQL SERVER 2008请使用语句：(String)Dts.Variables["Partition"].Value;进行强制，不要使用Dts.Variables["User::Partition"].Value.ToString(); )：
#region Help: Introduction to the script task /* The Script Task allows you to perform virtually any operation that can be accomplished in * a .Net application within the context of an Integration Services control flow. * * Expand the other regions which have "Help" prefixes for examples of specific ways to use * Integration Services features within this script task. */ #endregion #region Namespaces using System; using System.Data; using Microsoft.SqlServer.Dts.Runtime; using System.Windows.Forms; using Microsoft.AnalysisServices; #endregion namespace ST_4038a8110570463994b546d9f7d48b3d { [Microsoft.SqlServer.Dts.Tasks.ScriptTask.SSISScriptTaskEntryPointAttribute] public partial class ScriptMain : Microsoft.SqlServer.Dts.Tasks.ScriptTask.VSTARTScriptObjectModelBase { #region ScriptResults declaration /// <summary> /// This enum provides a convenient shorthand within the scope of this class for setting the /// result of the script. /// /// This code was generated automatically. /// </summary> enum ScriptResults { Success = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Success, Failure = Microsoft.SqlServer.Dts.Runtime.DTSExecResult.Failure }; #endregion public void Main() { // TODO: Add your code here String sPartition = Dts.Variables["User::Partition"].Value.ToString(); String sCubeName = Dts.Variables["User::CubeName"].Value.ToString(); String sMeasureGroup = Dts.Variables["User::MeasureGroup"].Value.ToString(); String sServer = "localhost"; String sDataBaseID = Dts.Variables["User::DatabaseID"].Value.ToString(); String sCubeID = Dts.Variables["User::CubeID"].Value.ToString(); String sMeasureGroupID = Dts.Variables["User::MeasureGroupID"].Value.ToString(); String sDataSoureID = Dts.Variables["User::DataSoureID"].Value.ToString(); String sSQL = Dts.Variables["User::SQL"].Value.ToString(); String sMaxDateKey = Dts.Variables["User::MaxDateKey"].Value.ToString(); String sMinDateKey = Dts.Variables["User::MinDateKey"].Value.ToString(); String aSql = sSQL.Replace("where_clause", "where VisitDateID >=" + sMinDateKey + " and VisitDateID <=" + sMaxDateKey); ConnectionManager cm = Dts.Connections.Add("MSOLAP100"); cm.ConnectionString = "Provider=MSOLAP.4;Data Source=localhost;IntegratedSecurity=SSPI;Initial Catalog=" + sDataBaseID; Microsoft.AnalysisServices.Server aServer = new Server(); aServer.Connect(sServer); Microsoft.AnalysisServices.Database aDatabase = aServer.Databases.FindByName(sDataBaseID); CubeCollection cubeCollection = aDatabase.Cubes; foreach (Cube item in cubeCollection) { string name = item.Name; } Microsoft.AnalysisServices.Cube aCube = aDatabase.Cubes.FindByName(sCubeName); Microsoft.AnalysisServices.MeasureGroup aMeasureGroup; try { MeasureGroupCollection collection = aCube.MeasureGroups; aMeasureGroup = collection.FindByName(sMeasureGroup); } catch (Exception ex) { throw ex; } if (aMeasureGroup.Partitions.Contains(sPartition)) { Dts.Variables["User::IsNotePresent"].Value = false; Dts.Variables["User::Xmla_script"].Value = ""; Dts.TaskResult = (int)ScriptResults.Success; } else { Dts.Variables["User::IsNotePresent"].Value = true; Dts.Variables["User::Xmla_script"].Value = "<Create xmlns="http://schemas.microsoft.com/analysisservices/2003/engine">" + "<ParentObject>" + "<DatabaseID>" + sDataBaseID + "</DatabaseID>" + "<CubeID>" + sCubeID + "</CubeID>" + "<MeasureGroupID>" + sMeasureGroupID + "</MeasureGroupID>" + "</ParentObject>" + "<ObjectDefinition>" + "<Partition xmlns:xsd="http://www.w3.org/2001/XMLSchema" " + " xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:ddl2="http://schemas.microsoft.com/analysisservices/2003/engine/2" xmlns:ddl2_2="http://schemas.microsoft.com/analysisservices/2003/engine/2/2" xmlns:ddl100_100="http://schemas.microsoft.com/analysisservices/2008/engine/100/100" xmlns:ddl200="http://schemas.microsoft.com/analysisservices/2010/engine/200" xmlns:ddl200_200="http://schemas.microsoft.com/analysisservices/2010/engine/200/200">" + "<ID>" + sPartition + "</ID>" + "<Name>" + sPartition + "</Name>" + "<Source xsi:type="QueryBinding">" + "<DataSourceID>" + sDataSoureID + "</DataSourceID>" + "<QueryDefinition>" + aSql + "</QueryDefinition>" + "</Source>" + "<StorageMode>Molap</StorageMode><ProcessingMode>Regular</ProcessingMode>" + "<ProactiveCaching><SilenceInterval>-PT1S</SilenceInterval><Latency>-PT1S</Latency><SilenceOverrideInterval>-PT1S</SilenceOverrideInterval><ForceRebuildInterval>-PT1S</ForceRebuildInterval>" + "<Source xsi:type="ProactiveCachingInheritedBinding" /></ProactiveCaching>" + "</Partition>" + "</ObjectDefinition>" + "</Create>"; Dts.TaskResult = (int)ScriptResults.Success; } } } }
处理脚本返回值：如果@IsNotePresent是ture:就会将参数Xmla_script中的字符串传给下面的"Analysis Services 执行DDL任务"由它为度量值组生成分区；如果是false就返回null，不生成分区;
2.5、添加Analysis Services 执行 DDL 任务，处理返回值（即为度量值组生成分区）：
2.6、执行SSIS任务，查看分区生成情况：
