Can I find such a intelligent function to deal with all query conditions in database -


if want query in database, can use conditions, such select * user id=1; can define function :

bool query(int id,string tablename) {   database.id.equalto(id); }

if want find user less 18(age) years old:

bool query(int age,string tablename) {   database.age.lessthan(age); }

so 2 conditions have 2 function relative.

can find such way ,that 

bool query(string condition) { database.find(condition); //it deal condition intelligent use required function. }

i know database can read sql syntax. want find function can provide developer convenient way without writing sql syntax, pass condition sentence that: age<18, id=1. , function return result1.when enter arg>19 function return result2. not sure if have mention problem clearly. seeking help!

for php can use doctrine orm. doctrine 2 object-relational mapper (orm) php 5.4+ provides transparent persistence php objects.

the 'where' clause should need.

similar querybuilders exist in other languages. no need reinvent wheel.
