View Full Version : Filter boolean values from properties

10-07-2003, 04:04 AM
i have the following problem with one of my mdx-queries:
i define a member like:
member [Measures].[Ueberweisung] as '[Store].CurrentMember.Properties("Ueberweisung")'
with the following snippet from my schema:
<Property name="Ueberweisung" column="ueberweisung" type="Boolean"/>
i want to filter in the mdx for true/false values like e.g.:
NON EMPTY { Filter ( Descendants( [Store].[xxx].[yyy], [Store].[Name] ), ([Measures].[Ueberweisung] = 'true') ) } on rows
how do i have to specify the expression? i tried:
([Measures].[Ueberweisung] = 'true')
([Measures].[Ueberweisung] = "true")
([Measures].[Ueberweisung] = true)
([Measures].[Ueberweisung]) -> would expect it to evaluate to true/false because the property is a boolean
but i always get an exception like:
Caused by: java.lang.ClassCastException
at mondrian.olap.fun.FunUtil.getStringArg(FunUtil.java:57)
at mondrian.olap.fun.BuiltinFunTable$127.evaluate(BuiltinFunTable.java:4665)
i browsed through my mdx-books but there is _no_ info on booleans through my whole literature!

Try to cast the property to String type in clause WITH MEMBER and then use it in FILTER (in logical expression in comparison with string 'true'/'false'), e.g.:

WITH MEMBER [Measures].[Ueberweisung] AS CAST([Store].CurrentMember.Properties("Ueberweisung") AS String)
NON EMPTY { Filter ( Descendants( [Store].[xxx].[yyy], [Store].[Name] ), ([Measures].[Ueberweisung] = 'true') ) } ON ROWS

It should also be possible to use the boolean directly without casting. Something like:

Filter ( Descendants( [Store].[xxx].[yyy], [Store].[Name] ), [Store].CurrentMember.Properties("Ueberweisung") = true )
