Hello marc,
yes you are right,that there is no need to explicitly ask the user to "select relation arrows",
but i want to provide users with an option to select the Join type(inner,outer,left,right).
i have not mentioned any details for writing Nested Sub queries.till now i don't have a good design to implement them......and am still working on it.
Thanks
Ankit

I had a look at your image. I'm not sure what you mean by "select the
relations arrows which we need for the query". I think that in a query
builder, the user should be able to specify what he needs just in terms
of tables and columns, and the product should build the correct joins.
