Could you give a try to another DB server? For example query the linux
mysql server from the Solaris machine, if it is accessible.
I've tried (remotely) with the gentoo linux db (MySQL 5.0.60) but
happens the same as at solaris MySQL db (v5.0.51)....Returns value type
as DOUBLE.
Thank you very much for the debug lines! I think SER simply uses the
field types returned by the mysql server, so there might be a problem
with the server or library. You can check what the field types are along
with their names returned by the server in modules/mysql/res.c, search
for the mysql_fetch_fields function.

I'll look for that file. thanks Miklos.

Do the two machines query the same database server?
No, they don't. They are stand-alone with its respective (local) mysql
db.
There might be a problem with the field types, please check that they
are strings, and not blobs. Please send me a "describe trusted" mysql
output.

Casually, i add a few DBG() calls on 'trusted.c' and now at log see
these messages:

Seem that VAL_TYPE of "val + 2" isn't STRING, read it as DOUBLE
(DB_DOUBLE = 1).
Do not know why.
And because of this the 'if' conditions never are satisfy on trusted.c
(line #396):
if ((ROW_N(row + i) == 3) &&
(VAL_TYPE(val) == DB_STRING) && !VAL_NULL(val) &&
(VAL_TYPE(val + 1) == DB_STRING) && !VAL_NULL(val
+ 1) &&
(VAL_TYPE(val + 2) == DB_STRING) && !VAL_NULL(val
+ 2)) {
