Hi everyone,
I'm working on a project and one of my task is trying to take the "where" part of the queries.I'm programming inside the function "exec_simple_query" in "postgres.c".I searched inside the source code and how I've understood I need to take the "varattno" in "args" in "qpqual", is it right?If yes, how do I have to save it in order to have it in that function?If no, what is the easiest way to take it?
Example: For a query: select firstname from friend where age=33The attributes of the table friends are: firstname, lastname, city, state, ageI need to have the number 5 because "age" is the fifth attribute of "friend".
Thanks
