我想在Pentaho bi服务器中通过CDA从ktr文件创建图表
<?xml version="1.0" encoding="UTF-8"?>
<CDADescriptor>
<DataSources>
<Connection id="weather" type="kettle.TransFromFile">
<KtrFile>farzanspoon.ktr</KtrFile>
<variables datarow-name="PHONE" variable-name="TEMP"/>
</Connection>
</DataSources>
<DataAccess access="public"
cache="true"
cacheDuration="3600"
connection="weather"
id="current"
type="kettle">
<Columns/>
<Parameters>
<Parameter default="9121901111"
name="PHONE"
type="String"/>
</Parameters>
<Query>current_conditions</Query>
<Output indexes="0,1"/>
</DataAccess>
</CDADescriptor>
在CDA中我发送电话号码作为TEMP(变量在ktr中定义)但得到此错误
&#34;执行查询时出错&#34;
this是我的ktr和db
