> -------------------------------------------
>
> Key: OODT-546
> URL: https://issues.apache.org/jira/browse/OODT-546
> Project: OODT
> Issue Type: Bug
> Components: xmlps
> Affects Versions: 0.5
> Reporter: Michael Joyce
> Fix For: 0.6
>
> Attachments: dump.sql, ps.xml

> When the default table is set to an existing table name, XMLPS tries to inner
> join the default table with itself, resulting in a failed query.
> Example
> With the following ps.xml file
> <oodt:xmlps xmlns:oodt="http://incubator.apache.org/oodt/0.1-incubating";
> name="CERC Query Handler" id="EDRN.CERC.CancerData">
> <!--<tables default="Table1">-->
> <tables default="Cancer_Data">
> <table name="Cancer_Data" join="STUDY_PARTICIPANT_ID_SITE_TEXT"
> tofld="STUDY_PARTICIPANT_ID_SITE_TEXT"/>
> </tables>
> <field type="dynamic" name="STUDY_PARTICIPANT_ID"
> dbname="STUDY_PARTICIPANT_ID_SITE_TEXT" />
>
> <field type="constant" name="BASELINE_CANCER-CONFIRMATION_CODE" value="1"/>
> </oodt:xmlps>
> A query to
> http://localhost:8080/web-grid/prod?q=RETURN%3DSTUDY_PARTICIPANT_ID
> Results in the following:
> WARNING: Error executing sql: [SELECT
> Cancer_Data.STUDY_PARTICIPANT_ID_SITE_TEXT as STUDY_PARTICIPANT_ID FROM
> Cancer_Data INNER JOIN Cancer_Data ON
> Cancer_Data.STUDY_PARTICIPANT_ID_SITE_TEXT =
> Cancer_Data.STUDY_PARTICIPANT_ID_SITE_TEXT ]: Message: Not unique
> table/alias: 'Cancer_Data'
> If the default table is changed to "Participant_Data" then the query
> functions fine.
