Amit suggested another option in another mail, so total viable
solutions that are discussed as of now are,
1. Single API with NULL input treat as invalid value
2. Multiple API to deal with NULL input of other values
3. Single API with NULL value to treat them as current user, current
database
and NULL queryid.
4. Single API with -1 as invalid value, treat NULL as no matching. (Only
problem
with this approach is till now -1 is also a valid queryid, but setting -1
as queryid
needs to be avoided.
I prefer single API. I can go with either 3 or 4.
opinion from others?
