Right. That is what the 'text' type is there for.
> I wouldn't be terribly opposed to having an option to be set to allow this,
No need. Just let the 'text' type get into the SQL standard, if it is not
already there.

don't think SQL has one. I would guess it was
simplicity (of the definition of SQL), not withstanding the fact that SQL
is spuriously complicated in other things.

The 'problem' is in the output from the "mysql" program:
known
problems with the float type. Maybe this is one of them (in the function
sum).

your opions and experiences, good or bad.
I have made the move from Postgres to MySQL for speed reasons. Postgres
has more features but is slow---and not that very stable either. With
MySQL I am experiencing speed improvements of 10 to 50 times faster over
Postgres, and I am not experiencing any l

e result, can you? You are in a
limbo.
If (2), the MYSQL structure must be a newly created one, since you did not
pass any! And voila, you have created a MYSQL structure without mysql_init
(this is of course is in contradiction with the rest of the
documentation).

Not with LOAD_FILE, according to the Manual. You must do it inside your
application i.e. read the file and generate the corresponding SQL
statement using your programmatic means. Do not forget to escape the
necessary characters (NUL, \, ', ", I thin
al poster for an example. But anyway I think Carl has guessed
correctly what was on the poster's mind and yes Carl the rest of your

It is good we found your bug now!
There is still the question of your mysql monitor seemingly yelding the
right results for the wrong query, but I'll leave that problem for you now
;-)

I know K&R (section 4.9, 2nd ed.) says
char s[] = "...";
is equivalent to
char s[] = { . . . , '\0'}
but I always explicitely attach the \0 just to be sure i.e.
char s[] = "...\0";
/* mysql, database (cheating the filter, human reader ignore) */
n a file, then input to mysql --> success :-)
This fits my diagnosis that it has to do with concurrent access to the
same table.

Te sugiero que veas la página http://mmmysql.sourceforge.net/ por un JDBC y
en su docs vas a encontrar ejemplos de como resolver tu problema.
Si necesitas mayo ayuda, no tengo problema en enviarte porciones de código
donde se resulve este problema.

I know that in Oracle it is possible to select a number
from DUAL and put it in a variable. Is it possible
In mysql? and how?
Thanks
