I would like to search for PR's that have an empty date field.  I have tried
a number of variations which do not match PRs.  I am using GNATS 4.0 on a
Linux server.

 

The following queries do not match any PRs:

Verify-Date==""  

Verify-Date!=""

Verify-Date<"1"

Verify-Date>"1"

 

 

For example the following query does not generate any records

query-pr -d default --expr Verify-Date=="" --summary

 

 

thanks

Stuart
