DDSXTY14 — Add Unions to types supported in Queries and Filters

  • Key: DDSXTY14-1
  • Status: open  
  • Source: Object Computing, Inc. - OCI ( Mr. Adam Mitz)
  • Summary:

    "Member Names" ( is missing support for Unions. Union members can be accessed by name as long as a reserved name is specified for the discriminator. A valid filter expression needs to check the discriminator before accessing another member name (for example u.disc = 3 AND u.val < 100), however the implementation doesn't need to check for this. If evaluating a filter expression causes access to an inactive element of a union, the result is undefined.
