1. In postgresql create the test_nva and test_ table by the following script:

CREATE TABLE public.test_nva ( id integer, type character varying(4000), start_date date ); INSERT INTO public.test_nva(id, type, start_date) VALUES (1, 'str_val', '2015-07-02');

2. Add postgresql database configuration in standalone-teiid.xml

<datasource jndi-name="java:/test_pg" pool-name="test_pg" enabled="true" use-java-context="true"> <connection-url>jdbc:postgresql://localhost:5432/test?charSet=utf8</connection-url> <driver-class>org.postgresql.Driver</driver-class> <driver>org.postgresql</driver> <pool> <min-pool-size>2</min-pool-size> <max-pool-size>70</max-pool-size> <prefill>false</prefill> <use-strict-min>false</use-strict-min> <flush-strategy>FailingConnectionOnly</flush-strategy> </pool> <security> <user-name>postgres</user-name> <password>xxxxxx</password> </security> <validation> <check-valid-connection-sql>select 0</check-valid-connection-sql> </validation> <timeout> <blocking-timeout-millis>120000</blocking-timeout-millis> <idle-timeout-minutes>5</idle-timeout-minutes> </timeout> </datasource>

3. Add in test-vdb.xml java:/test_pg configured in previous step as datasource:

<model name="test_pg"> <property name="importer.useFullSchemaName" value="false"/> <property name="importer.tableTypes" value="TABLE,VIEW"/> <property name="importer.importKeys" value="false"/> <source name="test_pg" translator-name="myPg" connection-jndi-name="java:/test_pg"/> </model> <translator name="myPg" type="postgresql"> <property name="SupportsNativeQueries" value="true"/> </translator>

4. Configure in the test-vdb.xml the following virtual procedure:

<model visible = "true" type = "VIRTUAL" name = "views"> <metadata type = "DDL"><![CDATA[ CREATE VIRTUAL PROCEDURE pr0 (arg0 string) RETURNS (col0 integer, col1 string) AS BEGIN SELECT 1 as col0, '2017-01-01' AS col1 FROM (select '{"meta":1}' as val) w ,XMLTABLE( XMLNAMESPACES ('http://www.w3.org/2001/XMLSchema-instance' as "xsi") ,'/root/bounce_rate' PASSING JSONTOXML('root', w.val) COLUMNS col0 integer ,col1 string ) some_alias; END ]]> </metadata> </model>

5. Run the following query:

SELECT * FROM (SELECT 'League' AS type, 1 AS arg0) xxx, "test_pg.test_nva" dl, table(CALL "views.pr0"(arg0)) x JOIN "test_pg.test_nva" d ON d.type = 'str_val' ;;

or

SELECT * FROM (SELECT 'League' AS type, 1 AS arg0) xxx, "test_pg.test_nva" dl, table(CALL "views.pr0"(arg0)) x JOIN "test_pg.test_nva" d ON x.col1 = d.start_date AND d.type = 'str_val' ;;

It seems that in the x.col1 = d.start_date comparison the d.start_date must be converted to string explicitly but I don't know if it's a bug or not, if we indeed must use the conversion here explicitly.
