How to evaluate process input string?

Level 2
Level 2


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

Can you use a DecisionPoint and set up different route conditions for each possible query?

Thank you for the reply.

I made it work by using Set Value then route conditions.

I assign the string length to a process integer. then check if the integer is 0 or not.

But I am not sure what form will submit when user didn't give a value. will firm submit "null"  or empty string, Can I define empty string as default value?

on form field?

Thanks again.

It will submit an empty string. There is no concept of null in xml data. Everything is treated as a string.
