Stored procedure cannot be called using "Procedural Relational Command" ----------------------------------------------------------------------- Key: TEIID-1780 URL: https://issues.jboss.org/browse/TEIID-1780 Project: Teiid Issue Type: Bug Components: Server Affects Versions: 7.4.1 Reporter: Filip Nguyen Assignee: Van Halbert Priority: Blocker I wasn't able to call stored procedure using procedural relation command ([SOA Platform docs | http://documentation-stage-01.lab.eng.bne.redhat.com/docs/en-US/JBoss_Ent...], [teiid docs | http://docs.jboss.org/teiid/7.5.0.Final/reference/en-US/html_single/#proc...]). I was trying to do so on MySql 5.1 using this simple stored procedure: {code:title=Stored procedure|borderStyle=solid} CREATE PROCEDURE getEmployeeSurnames BEGIN SELECT surname FROM employees END {code} The VDB file contains following (I am attaching the vdb file): {code:title=DbData.xmi|borderStyle=solid} <relational:Procedure xmi:uuid="mmuuid:c4ebdcbb-87d9-4737-8107-f34481cb8406" name="getEmployeeSurnames" nameInSource="getEmployeeSurnames"> <result xmi:uuid="mmuuid:7620c452-417e-478b-a6bf-ee1529c98048" name="ResultSet"> <columns xmi:uuid="mmuuid:33f34ec9-4f4f-4d23-8cad-cc6184928b0d" name="surname" length="255"> <type href="http://www.w3.org/2001/XMLSchema#string"/> </columns> </result> </relational:Procedure> {code} The Java code I used to invoke the procedure: {code:title=Java snippet|borderStyle=solid} protected List<String> callGetEmployeeSurnames(boolean useCache) throws Exception { List<String> surnameList = new ArrayList<String>(); String[] connectionProps = useCache ? new String[] {"resultSetCacheMode=true"} : new String[] {}; String query = "select * from getEmployeeSurnames"; Connection conn = getTeiidConnection(VDBNAME, connectionProps); Statement cs = conn.createStatement(); cs.execute(query); ResultSet rs = cs.executeQuery(query); while (rs.next()) { surnameList.add(rs.getString(1)); } conn.close(); return surnameList; } public Connection getTeiidConnection(String vdbName, String ... props) throws Exception { StringBuilder connectionProps = new StringBuilder(); for (String p : props) { connectionProps.append(";" + p); } String url = "jdbc:teiid:" + vdbName + "@mm://127.0.0.1:31000" + connectionProps.toString(); Class.forName("org.teiid.jdbc.TeiidDriver"); Connection conn = DriverManager.getConnection(url, "admin", "teiid"); return conn; } {code} The exception on server was: {code:title=sever.log|borderStyle=solid} java.lang.NullPointerException at
