Looking at the code of mysql.d I see a big switch with many

"case 0x01: // TINYINT". But then there's the SQLType enum

(and also in
other parts of the code?)

Ah, I see.
The last commit is 6 months old.
I tried to compile mysql.d
---
> dmd -c mysql.d
/usr/share/dmd/src/phobos/std/exception.d(492): Error:
constructor mysql.MySQLException.this (string msg, string
file, uint line) is not callable using argument types
(string,string,ulong)
/usr/share/dmd/src/phobos/std/exception.d(492): Error: cannot
implicitly convert expression (line) of type ulong to uint
mysql.d(105): Error: template instance

It's sad. I always want to give D a chance. And when I do I
always bump into errors and inconveniences.
I thought, maybe the project is 6 months old, it's not
compatible anymore with the current DMD (but my code really
doesn't break at all with new Ruby versions, for example). I
thought of trying to fix the error. Apparently I need to
compile it with -m32 so that lengths of arrays are uint
instead of ulong.

(What does it mean "cannot cast"? Give me the reason,
please...)
Or maybe instead of the flag the code is wrong and instead of
uint it needs to be size_t. But I still get errors.
Every time I want to start coding in D, or helping some
project, I stumble into all kind of troubles.
But I wonder... is this case in particular D's fault or the
library's fault? (if the answer is "the project is 6 months
old, of course it won't compile" then it's D's fault)
Ah, finally, someone has found Steve Teale's batcave. It seems
that you are not too far from having it compiled. If you end up
succeeding, maybe you can propose him to update his file, so
that we can benefit ?
Looking at his code, it seems to me that he is very far from
the original goal, which was to make a generic database driver.
This one seems completely linked to MySQL and will need to be
completely rewritten for Postgres. Am I wrong ?
OK, never mind, I should have read before jumping in. I asked
where this code was a few weeks ago, and got no answer, so I'm
quite glad that this comes up. I haven't tested the driver, but
at least, it compiles fine.
