Description

A delete query against a view fails, when in WHERE clause there is a filter on non-directly mapped column. Please note, that the integer type is only example, this happens for any type (time/date/timestamp amongst other).

vdb

<vdb name="teiidVdb" version="1">
    <model name="Source" type="PHYSICAL" visible="false">
        <source name="jdg7-source" translator-name="infinispan-hotrod" connection-jndi-name="java:/jdg71HotrodDS" />
        <metadata type="DDL"><![CDATA[
             CREATE FOREIGN TABLE SmallA (
               IntValue string,
               StringKey string PRIMARY KEY
               ) OPTIONS(UPDATABLE true, "teiid_ispn:cache" 'jdg71_crud_null');
            ]]>
        </metadata>
        <metadata type = "NATIVE"/>
    </model>
    <model name="CRUD" type="VIRTUAL">
       <metadata type="DDL"><![CDATA[
           CREATE VIEW SmallA(
               IntValue integer,
               StringKey string PRIMARY KEY
           ) OPTIONS (UPDATABLE true) AS
           SELECT
               CONVERT(source.IntValue,integer), source.StringKey FROM Source.SmallA as source;
	   CREATE TRIGGER on SmallA INSTEAD OF INSERT AS FOR EACH ROW
	   BEGIN ATOMIC
               INSERT INTO Source.SMallA(StringKey,IntValue) VALUES (NEW.StringKey, CONVERT(NEW.IntValue,string));
	   END;
        ]]>
       </metadata>
    </model>
</vdb>

And following query:

DELETE query

DELETE FROM SmallA WHERE IntValue=13

I get an error:

This happens on both empty and non-empty cache.
For a column, which is directly mapped from a source column to view column, such problem doesn't exist.
Given the limited type support on JDG's side I consider this blocking issue, as there's no workaround for such operation.
