[teiid-issues] [JBoss JIRA] (TEIID-5380) Disallow the default option for a function parameter

Disallow the default option for a function parameter ---------------------------------------------------- Key: TEIID-5380 URL: https://issues.jboss.org/browse/TEIID-5380 Project: Teiid Issue Type: Bug Reporter: Jan Stastny Assignee: Steven Hawkins Currently there's no support in Teiid for default values for parameters of a Function. But [Function element in BNF for SQL Grammar|https://teiid.gitbooks.io/documents/content/reference/BNF_for_SQL_Grammar.html#createDDLProcedure] shares the definition with Procedure, which permits to deploy such a VDB, where there are DEFAULT values defined on a Function parameter. So a VDB with following DDL shouldn't deploy successfully: {code:sql} CREATE VIRTUAL FUNCTION f1(e2 string NOT NULL DEFAULT 'default') RETURNS string AS BEGIN RETURN e2; END; {code}
