CMQL bug in 2015.3 and, 2016.1

[Michael Cohen]

The good news is that you get an error rather than an incorrect result.

The problem is with queries that include both a literal and a empty string. For example:

MV:LIST VOC WITH F1 "F" ""

[7012] CMQL: Fatal internal error - invalid query tree.

Please prepare the following information and contact Intersystems support:

  o As much detail as possible regarding the CMQL statement

  o As much detail as possible regarding the DICT of the file(s) in question

  o Provide the information between the == lines below

 ===========================================================================

  Exception message       : org.antlr.runtime.UnwantedTokenException

  Recognizer line         : 0

  Tree line               :

  Node description        :

===========================================================================

 

Same error for:

MV:LIST VOC WITH F1 EQ "F" OR ""

 

This problem happens in:

2015.3

2016.1

2016.2
