Class SubqueryConjunctionTest

java.lang.Object
ubic.gemma.persistence.util.SubqueryConjunctionTest
public class SubqueryConjunctionTest extends Object
A Subquery may carry several conjoined filters, so that they bind to the SAME element of a to-many relation.

The distinction this exists for: two separate subqueries ask "has a characteristic valued X" AND "has a characteristic categorised Y", which is satisfied by a dataset where those are two different characteristics. One subquery over two filters asks for a single characteristic that is both — the only form that can express "this gene URI, as a genotype".

    • bothConditionsAreRenderedInsideASingleSubquery

      @Test public void bothConditionsAreRenderedInsideASingleSubquery()
      Both conditions land in ONE subquery, joined by `and`, against one alias.

    • everyRenderedParameterIsBound

      @Test public void everyRenderedParameterIsBound()
      Rendering and binding derive parameter names independently; if they drift, the query builds and then dies at bind time. Conjunct 0 must keep the name it had when a subquery held one filter.

    • singleFilterSubqueryIsUnchanged

      @Test public void singleFilterSubqueryIsUnchanged()
      A single-filter subquery must render and bind exactly as it did before conjunctions existed.

    • getFilterRefusesToSpeakForAConjunction

      @Test public void getFilterRefusesToSpeakForAConjunction()
      getFilter() is only meaningful for a single filter; a conjunction must be read via getFilters().
