MDX函数使用介绍（四）：字符串函数&元组函数

       字符串函数

函数	描述
CalculationPassValue	返回在多维数据集的指定计算传递上对 MDX 表达式求得的值。
	with member measures.test as ' CalculationPassValue ( membertostr ([sales average]) , -1, RELATIVE)' select  {measures.test, [sales average] } on columns ,   { [Time] .allmembers } on rows from Sales 上面的语句按理是对的，但不能运行！待改！
CoalesceEmpty	将空单元值合并为字符串或数字。
	with member measures.test as ' CoalesceEmpty (Time .currentmember.Parent.Name , "EMPTY" )' select  {measures.test } on columns ,   {time .allmembers } on rows from Sales 能运行但不是预想效果
Generate	返回通过在集合上对字符串表达式计算而创建的连锁字符串。
	看上面的
IIf	返回由逻辑测试确定的两个字符串或数值之一。
	with member measures.test as ' iif ( isempty (Time .currentmember.Parent )   , "EMPTY" , "exist" )' select  {measures.test } on columns ,   {time .allmembers } on rows from Sales
LookupCube	返回在同一数据库中另外一个指定的多维数据集上对 MDX 表达式求得的值。
	看上面的
MemberToStr	从某个成员构造一个字符串。
	with member measures.test as ' MemberToStr ([store Sales]) ' select  {measures.test } on columns ,  { [Time] .allmembers } on rows from Sales
Name	返回维度、层次结构、级别或成员的名称。
	略
Properties	返回包含成员属性值的字符串。
	with member measures.test as 'store .currentmember.Properties ( "Store Manager" ) ' select  {measures.test } on columns ,  { Descendants ([Store].[All Stores].[USA],[Store].[Store Name])} on rows from Sales
SetToStr	用集合构造一个字符串。
	select  {measures.[store sales] } on columns ,  { strtoset ( SetToStr ({[Time].[1997], [Time].[1998]}))} on rows from Sales
TupleToStr	用元组构造一个字符串。
	with member [measures].[TupleToStr] as ' TupleToStr (([Measures].[Sales Count], [Store].[All Stores].[USA])) '    SELECT  { [measures].[TupleToStr] } ON COLUMNS , [Store] .allmembers ON rows from sales
UniqueName	返回维度、级别或成员的唯一名称。
	略
UserName	返回当前连接的域名和用户名。
	with member measures.test as ' username ' select  { measures.test } on columns ,  { [Time].[1997], [Time].[1998]}  on rows from Sales

 

元组函数

函数	描述
Current	返回迭代过程中集合中的当前元组。
	with set kkk as '{{[Time].[1997], [Time].[1998]}*{[Store].[All Stores].[Canada],[Store].[All Stores].[USA]} }' member measures.jjj as ' TupleToStr (kkk .current )', solve_order =1 select  { measures.[store sales],measures.jjj } on columns ,  {kkk} on rows from Sales 待改！找不到current的用途！
Item	从集合中返回元组。
	with set kkk as '{{[Time].[1997], [Time].[1998]}*{[Store].[All Stores].[Canada],[Store].[All Stores].[USA]} }' member measures.jjj as ' TupleToStr (kkk .item (0) .item (0))', solve_order =1 select  { measures.[store sales],measures.jjj } on columns ,  {kkk} on rows from Sales
StrToTuple	用字符串构造一个元组。
	with member measures.jjj as ' StrToTuple ( "([store Sales], " +time .currentmember.uniquename + ")" )', solve_order =1 select  { measures.jjj } on columns ,  {time .allmembers } on rows from Sales
