I need to create an OLAP View just from one table in MySQL.
I need to get information from the following columns in my table: Date, Machine, Level, Item, Code, Comment, Downtime.
So I created this Mondrian Schema:
<Schema name="ExampleSchema">
<Cube name="ExampleCube">
<Table name="example_table"/>
<Dimension name="Date">
<Hierarchy hasAll="true" allMemberName="All Date">
<Level name="Date" column="date" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Machine">
<Hierarchy hasAll="true" allMemberName="All Machine">
<Level name="Machine" column="machine" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Level">
<Hierarchy hasAll="true" allMemberName="All Level">
<Level name="Level" column="level" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Item">
<Hierarchy hasAll="true" allMemberName="All Item">
<Level name="Item" column="item" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Code">
<Hierarchy hasAll="true" allMemberName="All Code">
<Level name="Code" column="code" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Dimension name="Comment">
<Hierarchy hasAll="true" allMemberName="All">
<Level name="Comment" column="comment" uniqueMembers="true"/>
</Hierarchy>
</Dimension>
<Measure name="Downtime" column="downtime" aggregator="sum" formatString="Standard" visible="true"/>
</Cube>
</Schema>
My query looks like follows:
{[Item].[All Item]} * {[Measures].[Downtime]}
ON columns,
{[Code].[All Code]} * {[Comment].[All Comment]}
ON rows
from [ExampleCube]
WHERE
{([Date].[2011-11-31], [Machine].[1500], [Level].[AB])}
It works, but I want to have measures not for a single date, but for a period of time (from the start date till the end date).
Try using the range operator
:
Both dates
[Date].[2011-11-31]:[Date].[2015-06-25]
must exist within your cube.
