Re: default table type = innodb is stable??
- Original Message - From: Hiu Yen Onn [EMAIL PROTECTED] if i uncomment it, then mysql server wont start at all. if i comment it, then, that's ok. please advise. thanks again If the mysql server does not start it will probably leave a lot of messages in the error log. If you send the section of the error log about such a failed start to the list people here can most likely help you find the problem with your server.

Re: Problem with GRANT not working.
Hello. Enable a General log and find out what is MySQL thinking about the host from you're connecting to it. Ben Clewett wrote: Dear MySQL, A new installation of 4.1.9 on AIX 5.

Statement-metadata for decimal-column
Hi,
I have a problem with the statement-api. I try to select a value of type
decimal(12,2) from a mysql-database. To get information about this column, I
use mysql_stmt_result_metadata. The problem here is, that the type of the
column is 0. When I try to use it in a MYSQL_BIND-structure and call
mysql_stmt_bind_result, I get error 2036: Using unsupported buffer type: 0.
For other column-types I get reasonable values.
I attach a minimal program, which reproduces the error.
My configuration: Mysql-version 4.1.13 on SuSE-Linux 10.0, x86-64.

is being restarted. If mysql.reconnect = 1, mysql_ping() returns
success, otherwise we have Server has gone away. Here is the test program:

Hi,
I have just tried your routine, I use something very similar, (I have changed

error remains the same. That is what got me wondering in the first place.
