JSON production functions JSONOBJECT and JSONARRAY_AGG producing CLOBs ---------------------------------------------------------------------- Key: TEIID-5728 URL: https://issues.jboss.org/browse/TEIID-5728 Project: Teiid Issue Type: Bug Components: Query Engine Reporter: Ramesh Reddy Assignee: Steven Hawkins Priority: Major JSON production functions like JSONOBJECT and JSONARRAY_AGG seem to be still returning a clob object rather than a 'json' object even though Teiid has the first class data type for json now. for ex: {code} CREATE VIRTUAL PROCEDURE CustomerJSON(IN p1 integer) RETURNS TABLE (json_out json) OPTIONS (UPDATECOUNT 0, "REST:METHOD" 'GET', "REST:URI" 'CustomerJson/{p1}') AS BEGIN SELECT JSONOBJECT(JSONARRAY_AGG(JSONOBJECT(SSN, Name))) AS json_out FROM accounts.customer; END {code} would fail with {code} Caused by: org.teiid.deployers.VirtualDatabaseException: TEIID40095 TEIID31080 virt.CustomerJSON validation error: TEIID31121 The expected result set of the procedure virt.CustomerJSON does not match the result set from returnable statement SELECT JSONOBJECT(JSONARRAY_AGG(JSONOBJECT(SSN, Name))) AS json_out FROM accounts.customer; use WITHOUT RETURN to indicate the statement should not be returned - The definition for virt.CustomerJSON has the wrong type for column 1. Expected json, but was clob. at org.teiid.runtime.EmbeddedServer.deployVDB(EmbeddedServer.java:845) ~[teiid-runtime-12.2.0-SNAPSHOT.jar:12.2.0-SNAPSHOT] at org.teiid.spring.autoconfigure.TeiidServer.deployVDB(TeiidServer.java:315) ~[classes/:na] ... 17 common frames omitted {code}
