[teiid-issues] [JBoss JIRA] (TEIID-5725) Please improve documentation on definition of stored procedures, virtual functions and virtual procedures

[ https://issues.jboss.org/browse/TEIID-5725?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-5725: --------------------------------------- There are two aspects here, one is if there is documentation for the base (non-odata) case. And the other is what is documented with regards to odata. The former is mostly covered. The latter is touched on only briefly. Do you mostly need an expanded section in the OData docs discussing actions and functions as they relate to teiid procedures? There is no concept of an OUT or INOUT parameter in OData. There is only IN and RETURN. A result set returned from a procedure is mapped to a complex return value. Are you asking from an OData or just sql perspective? OData metadata currently does not utilize Teiid defined functions. For core Teiid with a Java defined function see: http://teiid.github.io/teiid-documents/master/content/dev/Support_for_Use... For just DDL see: http://teiid.github.io/teiid-documents/master/content/reference/DDL_Metad... Create Procedure/Function - I'll update this page to use a table of contents and unfortunately it does not explicitly show the usage of a RETURN statement http://teiid.github.io/teiid-documents/master/content/reference/Procedure... {code} CREATE VIRTUAL FUNCTION CustomerRank(customerid integer) RETURNS integer AS BEGIN ... RETURN expression; END {code} Collections/arrays as parameters are not allowed in OData - I recall logging an issue against Olingo 2. A result set is mapped automatically to a complex type collection result. A array result will be mapped to a simple type collection. Multi-dimensional arrays are not supported by OData. -- This message was sent by Atlassian Jira (v7.12.1#712002)
