Hi Michael,
after tracing down the issue, I've a fix for it now. The problem was not
in reflecttable(). It was in moretableinfo() in mysql.py.
This a diff for mysql.py (not an elegant solution though):
361c361,365
< desc = c.fetchone()[1].strip()
---
> desc_fetched = c.fetchone()[1]
> if type(desc_fetched) is not str:
> # may get array.array object here
> desc_fetched = desc_fetched.tostring()
> desc = desc_fetched.strip()
Here are some explanations:
I have been testing on two machines, one running MySQL 4.1.11 and the
other MySQL 4.1.14. Python mysql library linked to
libmysqlclient_r.so.15 on client machine:
# ldd /usr/lib/python2.4/site-packages/_mysql.so
linux-gate.so.1 => (0xffffe000)
libmysqlclient_r.so.15 => /usr/lib/libmysqlclient_r.so.15
(0xa7e27000)
libz.so.1 => /usr/lib/libz.so.1 (0xa7e13000)
libpthread.so.0 => /lib/tls/libpthread.so.0 (0xa7e01000)
libcrypt.so.1 => /lib/tls/libcrypt.so.1 (0xa7dd3000)
libnsl.so.1 => /lib/tls/libnsl.so.1 (0xa7dbc000)
libm.so.6 => /lib/tls/libm.so.6 (0xa7d96000)
libc.so.6 => /lib/tls/libc.so.6 (0xa7c5e000)
/lib/ld-linux.so.2 (0x75555000)
After adding 2 lines to moretableinfo() to print c.fetchone()[1] and its
type, we have such results for server running MySQL 4.1.14:
>>> from sqlalchemy import *
>>> engine = create_engine("mysql://...")
>>> meta = BoundMetaData(engine)
>>> wTable = Table('WMSWarehouses', meta, autoload=True)
array('c', "CREATE TABLE `WMSWarehouses` (\n `WarehouseID` int(10)

we have array.array object here instead of str object

So the patch seems to be quite obvious.
