[teiid-issues] [JBoss JIRA] (TEIID-4244) Assertion failed error when joining duplicate rows to a table from other source

[ https://issues.jboss.org/browse/TEIID-4244?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-4244: ---------------------------------- Steps to Reproduce: 1. In postgresql create the test_a table by the following script: {code:sql} CREATE TABLE test_a ( a integer, b integer ); INSERT INTO test_a(a, b) VALUES (1, 1); INSERT INTO test_a(a, b) VALUES (1, 2); INSERT INTO test_a(a, b) VALUES (2, 1); INSERT INTO test_a(a, b) VALUES (2, 2); INSERT INTO test_a(a, b) VALUES (3, 2); INSERT INTO test_a(a, b) VALUES (3, 10); {code} 2. Add postgresql database configuration in standalone-teiid.xml {code: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> {code} 3. Add in test-vdb.xml java:/test_pg configured in previous step as datasource: {code:xml} <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> {code} 4. Run the query: {code:sql} select * from (select 3 as a, 3 as b union all select 1 as a, 1 as b union all select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a limit 10; {code} which will fail with ASSERTION FAILED error message. But the following query won't fail: {code:sql} select * from (select 1 as a, 1 as b union all select 3 as a, 3 as b) as t1 join test_pg.test_a t2 on t1.a=t2.a; {code} was: 1.
