[ https://issues.jboss.org/browse/TEIID-5561?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-5561: --------------------------------------- Thanks. Forgot to check the ABNF. That clarifies what is expected. Using the referenced TSimpleIdentifier pattern confirms that most non-letter characters are not accepted. That is a problem for us in that it's much more restrictive than SQL identifiers. The olingo metadata layer does not apply any restrictions, so we can create invalid metadata that is not queryable. It is possible to choose a naming replacement strategy similar to what is done with sql/xml names, but that will be a big change at first glance given our assumptions about the 1-1 mapping between odata and teiid metadata names. -- This message was sent by Atlassian Jira (v7.12.1#712002)
