[ https://issues.jboss.org/browse/TEIID-5461?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-5461: --------------------------------------- SQL Server has the same restriction as well. So we'll assume those in the Teiid implementation. There are other hive/impala frame restrictions, such as requiring the full between specification (handled by the translator) and eliminating additional frames (such as current row to current row - which is not yet accounted for). SQL Server does not allow range with n preceding/following, which we may do as well. The initial commit for 11.2 is at https://github.com/shawkins/teiid/commit/4ce82d4358709156d68948e0b22e2a69... It is large for a back port, but does not introduce much in terms of complexity - and should not be breaking in any way. -- This message was sent by Atlassian JIRA (v7.5.0#75005)
