[ https://issues.redhat.com/browse/TEIIDSB-227?page=com.atlassian.jira.plug... ] Fabian Knoll commented on TEIIDSB-227: -------------------------------------- [~shawkins]: So if it is a basically a blob I think the ST_GeomFromWKB() should work, as [~rareddy] shows in the example. Unfortunately  the following do not work. {code:java} package com.example.teidvdbless.teidvdblessapp; import org.locationtech.jts.geom.MultiLineString; import org.teiid.spring.annotations.SelectQuery; import javax.persistence.Column; import javax.persistence.Entity; import javax.persistence.Id; @Entity @SelectQuery("SELECT gid, ST_GeomFromWKB(geom), name FROM nyc.nyc_streets") public class Street { @Id int gid; @Column MultiLineString geom; @Column String name; {code} Error: {code:java} Caused by: org.teiid.deployers.VirtualDatabaseException: TEIID40095 TEIID31080 teiid.street validation error: TEIID30070 The function 'ST_GeomFromWKB(geom)' is a valid function form, but the arguments do not match a known type signature and cannot be converted using implicit type conversions. at org.teiid.runtime.EmbeddedServer.deployVDB(EmbeddedServer.java:854) ~[teiid-runtime-16.0.0-20201002.172031-63.jar:16.0.0-SNAPSHOT] at org.teiid.spring.autoconfigure.TeiidServer.deployVDB(TeiidServer.java:367) ~[teiid-spring-boot-starter-1.7.0-20200929.142219-2.jar:1.7.0-SNAPSHOT] ... 17 common frames omitted {code} -- This message was sent by Atlassian Jira (v7.13.8#713008)
