  e.revision <= :revision and (e.endRevision > :revision or e.endRevision is null)

Parameters:

globalCfg - the GlobalConfiguration

rootQueryBuilder - the QueryBuilder that will be updated

parameters - root parameters to which restrictions shall be added

revisionProperty - property of the revision column

revisionEndProperty - property of the revisionEnd column (only used for ValidityAuditStrategy)

alias2 - an alias used for subquery (only used for ValidityAuditStrategy)

inclusive - indicates whether revision number shall be treated as inclusive or exclusive
