SQL is almost the worst standard I've come across. Its the
computer equivalent of VHS. Its not readable by computer or humans. (Enough
Flaming on to why I think this)
SQL is verbose it often make you repeat your self when its obvious
what you mean.
INSERT INTO a (b,c) SELECT a+4 as b, c*6 as c from a;
SQL has many different ways of writing the same thing for
different purposes. eg
INSERT INTO a (b,c) VALUES (1,2);
UPDATE a set b=1, c=2 WHERE d=3;
Why not
INSERT INTO a set b=1, c=3;
its certainly more readable and consistent.
Parsing is hard work
No Meta Standard (How do you find out the structure of your table using
pure SQL?
Very difficult to operate with Trees and simple hierarchal data.
I could continue. Still its a language we all love to hate.
