I've tried that in the past. My conclusion was that in most cases, if you
want your queries to be flexible, use joins, where-clauses, etc, you end up
with exactly the same amount or work in writing the queries. Think about it:
if queries could be shorter, the SQL would be shorter. The advantage you do
get is an extra check wether a certain query is allowed to the specific
user, and you can control some of the output.
For a certain project specifically you could always try to figure out which
queries are used several times, and make a template for them. It won't save
you much coding time in my opinion though, but it will make your code more
readable.
Now I have a database object, that:
- takes car of connecting.
- saves querystrings and errors for debugging purposes.
- on selects returns a complete associative array, with (if existing) the
primary key as main key, 0 if no rows match, false if there's an error in
the query.
- on insert returns mysql_insert_id() (or array of insert_id()'s or false on
error.
- on updates and deletes returns the number of rows affected, or false on
error.
One thing that's usefull here that the object calls a certain
database-connection specifically, so it's easier when working with more than
one database in a script.
That's about as much as I can gain from it without inventing my own database
syntax. I'm no genius, and don't think I personally can replace SQL with a
better alternative :-).
