1. Add file resource adapter configuration in standalone-teiid.xml <resource-adapter id= "file" > <module slot= "main" id= "org.jboss.teiid.resource-adapter.file" /> <connection-definitions> <connection-definition class-name= "org.teiid.resource.adapter.file.FileManagedConnectionFactory" jndi-name= "java:/files" enabled= "true" pool-name= "files" > <config-property name= "AllowParentPaths" > true </config-property> <config-property name= "ParentDirectory" > C:/testdata </config-property> </connection-definition> </connection-definitions> </resource-adapter> 2. Add translator "myFiles" in /deployments/test-vdb.xml <translator name= "myFiles" type= "file" /> 3. Add "files" model in /deployments/test-vdb.xml <model name= "files" > <source name= "files" translator-name= "myFiles" connection-jndi-name= "java:/files" /> </model> 4. Configure in /deployments/test-vdb.xml the following virtual view and procedure (the emptydateranges.csv is in attachment): <model visible = "true" type = "VIRTUAL" name = "testcase" > <metadata type = "DDL" > <![CDATA[ CREATE VIRTUAL PROCEDURE proc_web_avg_visit_duration_empty( domain string ) RETURNS (i integer) AS BEGIN select 1; END CREATE VIEW testcase.dim_md_date_ranges AS SELECT "csv_table.id" FROM ( call files.getFiles( '/emptydateranges.csv' )) f, TEXTTABLE( to_chars(f.file, 'UTF-8' ) COLUMNS "id" INTEGER DELIMITER ';' HEADER 1 ) "csv_table" ]]> </metadata> </model> 5. Running the following query: SELECT id FROM ( SELECT d.id FROM ( SELECT 'l1' as domain ) dim_md_domains_to_load, table ( CALL testcase.proc_web_avg_visit_duration_empty( " domain " => domain )) x JOIN testcase.dim_md_date_ranges d ON true UNION SELECT id FROM testcase.dim_md_date_ranges ) z when using the following procedure: CREATE VIRTUAL PROCEDURE proc_web_avg_visit_duration_empty( domain string ) RETURNS (i integer ) AS BEGIN select 1; END leads to the following error message: 2017-07-19 19:57:12,608 ERROR [org.teiid.PROCESSOR] (Worker1_QueryProcessorQueue15) FOgTHY5kk50l TEIID30019 Unexpected exception for request FOgTHY5kk50l.1: org.teiid.core.TeiidCo mponentException: TEIID30328 Unable to evaluate dim_md_domains_to_load.domain: No value was available at org.teiid.query.util.CommandContext.getFromContext(CommandContext.java:514) at org.teiid.query.eval.Evaluator.internalEvaluate(Evaluator.java:766) at org.teiid.query.eval.Evaluator.evaluate(Evaluator.java:726) at org.teiid.query.processor.proc.ProcedurePlan.evaluateExpression(ProcedurePlan.java:857) at org.teiid.query.processor.proc.ProcedurePlan.open(ProcedurePlan.java:225) at org.teiid.query.processor.relational.PlanExecutionNode.open(PlanExecutionNode.java:82) at org.teiid.query.processor.relational.RelationalNode.open(RelationalNode.java:254) at org.teiid.query.processor.relational.JoinStrategy.openLeft(JoinStrategy.java:95) at org.teiid.query.processor.relational.NestedTableJoinStrategy.openLeft(NestedTableJoinStrategy.java:74) at org.teiid.query.processor.relational.JoinNode.open(JoinNode.java:145) at org.teiid.query.processor.relational.RelationalNode.open(RelationalNode.java:254) at org.teiid.query.processor.relational.RelationalNode.open(RelationalNode.java:254) at org.teiid.query.processor.relational.UnionAllNode.open(UnionAllNode.java:123) at org.teiid.query.processor.relational.RelationalNode.open(RelationalNode.java:254) at org.teiid.query.processor.relational.DupRemoveNode.open(DupRemoveNode.java:53) at org.teiid.query.processor.relational.RelationalNode.open(RelationalNode.java:254) at org.teiid.query.processor.relational.LimitNode.open(LimitNode.java:146) at org.teiid.query.processor.relational.RelationalPlan.open(RelationalPlan.java:136) at org.teiid.query.processor.QueryProcessor.init(QueryProcessor.java:231) at org.teiid.query.processor.QueryProcessor.nextBatchDirect(QueryProcessor.java:138) at org.teiid.query.processor.QueryProcessor.nextBatch(QueryProcessor.java:114) at org.teiid.query.processor.BatchCollector.collectTuples(BatchCollector.java:164) at org.teiid.query.processor.BatchCollector.collectTuples(BatchCollector.java:146) at org.teiid.dqp.internal.process.RequestWorkItem.processMore(RequestWorkItem.java:477) at org.teiid.dqp.internal.process.RequestWorkItem.process(RequestWorkItem.java:349) at org.teiid.dqp.internal.process.AbstractWorkItem.run(AbstractWorkItem.java:51) at org.teiid.dqp.internal.process.RequestWorkItem.run(RequestWorkItem.java:275) at org.teiid.dqp.internal.process.DQPWorkContext.runInContext(DQPWorkContext.java:282) at org.teiid.dqp.internal.process.ThreadReuseExecutor$RunnableWrapper.run(ThreadReuseExecutor.java:119) at org.teiid.dqp.internal.process.ThreadReuseExecutor$3.run(ThreadReuseExecutor.java:210) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.
