you may have another problem.
If you rebooted the box, mysqld may not have automatically started.
So, all of the sudden, the client can't connect to the socket since it is
not there as the server is not running.

Our experience has been totally the opposite.
We recently ported a Delphi application from MS-SQL to MySQL.
The MySQL server was a less powerful box than MS-SQL was running on.
I will not go into great detail because some of the software is proprietary
and we make $$$ providing the service.
It should be in mysql.h
Check your installation and make sure it was installed.
Our sysadmin originally installed MySQL without it - after all, he didn't
need it so it must not have been important ;)
Also, you will need to be sure and install the libmysqlclient and link with
it.

I am assuming this is not a MySQL question since MySQL interacts with SQL
commands that are all in characters.
try using strstream. You can poke just about anything into it and get a
string out.
If you must have a char*, then use the c_str() function of the string class.

The real answer, yes. It has a limit of several GB, depending on your OS.
It can take a huge string containing MBytes of BLOB data.

The practical answer is then pretty much no. (Probably

Am I missing something? Why would you have to create all of your columns as

Whether the has pool column is a TINYINT, BIGINT, or whatever, the SELECT
statement would be the same, wouldn't it?

You are 100% correct.
Since MySQL does not support cursors, I always put an auto_increment
column in my tables for just this purpose.

You are trying to telnet to the MySQL server.

I have run into the same issues and have given up on using MySQL++ interface
for that reason, plus it doesn't have the ability to update tables

That is, if you need to update anything, you have to define the table to a

Hi Robert -
The only way I have found to get this sort of stuff (as well as security

just like you would at the mysql client.
Then you can interpret the results that are returned.

Not an MySQL expert, but, I think what you are describing is a perfect use
of MERGE tables. They take up basically no space (except to contain the
names of the tables that are merged) and allow for you to merge these two
