Upgrading MySQL on RedHat 9
I am getting ready to try to upgrade MySQL on my RedHat 9 box. I want to go from the version that came with the distro (version 3.23.54) to the latest (verion 4.0). Just thought I'd post to get a heads-up on any known issues or prerequisites. I just hate it when I try something like this and screw up my whole installation. My planned steps are to: 1. mysqldump everything to a backup file 2. stop the service 3. uninstall all the current rpm's 4. install the fresh rpm's 5. startup 6. \. the file from step 1 Anything I need to lookout for?

Re: Insert statement with an ' in it
Well, the easiest thing is to "escape" any single quotes with a backslash character (\). PHP includes a function named addslashes() that does this. http://us4.php.net/manual/en/function.addslashes.php Same logic applies in other languages. Hope this helps. Andrew > Help!

Compiling with the C API
I have a question regarding compiling a C program with the mysql C api. >From the documentation, the only way I really see explained for compiling is a shell script that looks like this: CFG=/usr/bin/mysql_config sh -c "gcc -o $1 `$CFG --cflags` $1.c `$CFG --libs`" This works great when all my source code is in one file. However, I need to modularize things and do separate compile and link steps. When I do this, sh -c "gcc -o $1 `$CFG --cflags` $1.c" It complains that it cannot find the header file for mysql.h. This does not make sense to me. Also, I do not understand why I need to do the sh -c. Why can I not just do the gcc part here? I really want to build a makefile but I am just trying to take baby steps here (I am new to Linux programming). Thanks.

Re: Data types and the C API
Thanks Paul. After looking a little more closely at the documentation I
figured this out. The example there looks like this:
num_fields = mysql_num_fields(result);
while((row = mysql_fetch_row(result)))
{
unsigned long *lengths;
lengths = mysql_fetch_lengths(result);
for(i = 0; i < num_fields; i++)
{
printf("%.*s] ", (int) lengths[i], row[i] ? row[i] : "NULL");
}
printf("\n");
}
While this does not explicitely say that all columns are returned as
null-terminated strings, it is implied in the printf statement.
Thanks for you quick reply.

Data types and the C API
I am trying to learn to use the C API for MySQL and have a question. I
have a table that has a primary key defined as int(11). I don't know what
data type this translates to in C. I thought maybe an unsigned int or an
unsigned long. I have this little loop that cycles through the results of
a query and displays the first two columns, the first being the int(11)
and the second a varchar. Here is the code:
result = mysql_use_result(&mysql);
while((row = mysql_fetch_row(result))) {
printf("%lu %s\n", row[0], row[1]);
}
The first column is printed as garbage while the second column shows the
data correctly.
Help?
Thanks.
Andrew

Re: GRANT not working
I believe my problem was that I was omitting the word PRIVILEGES. I was doing just GRANT ALL ON... I also added *.* instead of * and @'localhost' and that got it working.

GRANT not working
I have a new installation of RedHat 7.3 and MySql. I had MySql working great on a Mandrake 8.0 installation. Now that I have reloaded this box with RH, I cannot get setup and working. I can run mysql as root and get in. I ran the commands below: >grant all on * to amp identified by 'blahdblah'; >flush privileges; Now when I run mysql like this: $mysql -u amp -pblahdblah I get the following error: ERROR 1045: Access denied for user: 'amp@localhost' (Using password: YES) I have a sneaking suspicion about the host but I don't know how to fix it.
