Hi,
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
Laura
