    How to evaluate process input string?

    livecycle Forum Screen



      I will need to do database queries in web service using input string as query parameters.

      But I need different queries depends on the input string values:

      e.g. input1, input2

      if input2 is empty or null, then do query one,

      if input 2 has value then do query two.


      But I don't know how to evalue a string input is null or empty string or with value.


      Can any one help?

      Many thanks
