如下schema代码片段:
<?xml version="1.0" encoding="UTF-8" ?>
<Schema name="报表">
<cube name="cube_qc_pass_item" caption="报表1" encoding="UTF-8">
<table name="fact_qc_pass_record_item_join">
<Dimension name="models" foreignKey="model_id" caption="模板">
<Hierarchy hasAll="true" allMemberName="model_name" primaryKey="id" primaryKeyTable="dim_qc_model">
<Table name="dim_qc_model" />
<Level name="model_name" column="name" caption="模板"/>
<Level name="model_id" column="id" caption="model_id"/>
</Hierarchy>
</Dimension>
<Measure name="times" column="id" aggregator="count" formatString="#,###0" datatype="Numeric" caption="总量"/>
</cube>
</Schema>
我想要在使用mdx查询的时候,使用model_name显示,使用model_id作为查询条件限制某个model_id,该如何书写mdx语句?
已经有如下错误的mdx语句了
mdx查询语句1:
SELECT
NON EMPTY {Hierarchize({{[Measures].[times], [Measures].[notPass], [Measures].[pass]}})} ON COLUMNS,
NON EMPTY {Hierarchize([models].[model_name].Members)} ON ROWS
FROM [cube_qc_pass_model] where [models].[model_id].[5cda6afa-f837-4603-af27-0915cfb812fd]
如下查询报错:
MondrianException: Mondrian Error:Hierarchy ‘[models]‘ appears in more than one independent axis.
mdx查询语句2:
SELECT
NON EMPTY {Hierarchize({{[Measures].[times], [Measures].[notPass], [Measures].[pass]}})} ON COLUMNS,
NON EMPTY Hierarchize(Union(CrossJoin([models].[model_name].Members, CrossJoin([times].[minute].Members, [agent_nos].[agent_no].Members)), CrossJoin([models].[model_id].[5cda6afa-f837-4603-af27-0915cfb812fd], CrossJoin([times].[minute].Members, [agent_nos].[agent_no].Members)))) ON ROWS
FROM [cube_qc_pass_model]
结果: 无效过滤
一直没有找到好的解决办法,变向实现了需求,来分享下:
首先改写schema文件,将model_name和model_id拆分成两个维度:
<?xml version="1.0" encoding="UTF-8" ?>
<Schema name="报表">
<cube name="cube_qc_pass_item" caption="报表" encoding="UTF-8">
<table name="fact_qc_pass_record_item_join">
<Dimension name="models" foreignKey="model_id" caption="模板">
<Hierarchy hasAll="true" allMemberName="model_name" primaryKey="id" primaryKeyTable="dim_qc_model">
<Table name="dim_qc_model" />
<Level name="model_name" column="name" caption="模板"/>
</Hierarchy>
</Dimension>
<Dimension name="model_ids" foreignKey="model_id" caption="模板id">
<Hierarchy hasAll="true" allMemberName="model_id" primaryKey="id" primaryKeyTable="dim_qc_model">
<Table name="dim_qc_model" />
<Level name="model_id" column="id" caption="model_id"/>
</Hierarchy>
</Dimension>
<Measure name="times" column="id" aggregator="count" formatString="#,###0" datatype="Numeric" caption="总量"/>
</cube>
</Schema>
使用如下语句查询,是可以查询到数据并实现了过滤的:
SELECT
NON EMPTY {Hierarchize({{[Measures].[times], [Measures].[notPass], [Measures].[pass]}})} ON COLUMNS,
NON EMPTY CrossJoin([models].[model_name].Members, CrossJoin([times].[minute].Members, [agent_nos].[agent_no].Members)) ON ROWS
FROM [cube_qc_pass_model] where [model_ids].[model_id].[5cda6afa-f837-4603-af27-0915cfb812fd]
