Your tree is wrong. I would expect that operator precedence is handled in the parser. The code generator will happily implement any tree, regardless of how insane it may be.
-----Ursprüngliche Nachricht----- Von: Prakash Premkumar [mailto:prakash.p...@gmail.com] Gesendet: Montag, 10. November 2014 10:40 An: General Discussion of SQLite Database Betreff: [sqlite] SQLite where clause tree The where clause in sqlite is encoded as a tree Let's say I have select statement like : SELECT * from employee where salary = 3+5*4+3; The tree which takes care of operator precedence is : = / \ salary + / \ 3 3 / * / \ 5 4 If I am constructing this tree for where clause by myself, should i take the operator precedence in to account while constructing it or will sqlite take care of precedence,given any tree (i.e constructing it with out taking precedence into account) ? Kindly give me some pointers towards this tree construction Thanks a lot for your time.
