Binary size problem
I compiles a C application which uses mysql library on two RedHat 9.0 machines. Both machines are using the same GCC and the same MySQL 4.0.16 : MySQL-client-4.0.16-0 MySQL-server-4.0.16-0 MySQL-devel-4.0.16-0 MySQL-shared-compat-4.0.16-0 gcc-3.2.2-5 gcc-c++-3.2.2-5 libgcc-3.2.2-5 In the MACHINE_1, the resulting binary size is about 20 KB, and in the MACHINE_2, the resulting binary is about 180 KB. Anyone can explain why in the MACHINE_2, the binary size is very big ? Here is my compile script : #!/bin/sh echo building $1 gcc -o $1 $1.c -I/usr/include/mysql -L/usr/lib/mysql -lmysqlclient -lz If I do strings to the binary from MACHINE_2 (180 KB), I saw (see below, not all). Is it possible that all the mysql libraries are statically linked ?

After installing MySQL 4.0.16 (rpm), it did not create /etc/my.cnf ?
Hi, My server is using RedHat 9.0. I just CHANGED the mysql from 3.23.58 (rpm) to 4.0.16 (rpm). What I did : # rpm -e all mysql 3.23.58 rpm # rm -rf /var/lib/mysql then install the 4.0.16 (rpm) # rpm -i MySQL-server MySQL-client ... MySQL-devel ... MySQL-shared-compat After this, I can start the server. I can change the root password using mysqladmin. I can create database. But I cant find /etc/my.cnf is this normal ? I verified by issuing: rpm -ql MySQL-server ... But again, I did not see /etc/my.cnf Anyone know what is the 'standard' my.cnf for MySQL 4.0.16 ? Thanks, __ Do you Yahoo!?

RE: After installing MySQL 4.0.16 (rpm), it did not create /etc/my.cnf ?
After I copied /usr/share/mysql/my-large.cnf it to /etc/my.cnf Then I restart mysql, and executed ps -ax I got this : 32175 pts/3S 0:00 /bin/sh /usr/bin/mysqld_safe --datadir=/var/lib/mysql --pid-file=/var/lib/mysql/myserver.pid 32200 pts/3S 0:00 /usr/sbin/mysqld --basedir=/ --datadir=/var/lib/mysql --user=mysql --pid-file=/var/lib/mysql/myserver.pid --skip-locking --port=3306 Why there is no reference to /etc/my.cnf there ? Because if I see in other 3.23.58 (rpm), it's like this : 2653 ?S 0:00 /bin/sh /usr/bin/safe_mysqld --defaults-file=/etc/my.cnf 2678 ?S 0:02 /usr/libexec/mysqld --defaults-file=/etc/my.cnf --basedir=/usr --datadir=/var/lib/mysql --user=mysql --pid-file=/var/run Something wrong with my 4.0.16 (rpm) installation ? Or should I edit something in the /etc/my.cnf ? it just straight copy from /usr/share/mysql/my-large.cnf Please help, Thanks --- Dathan Vance Pattishall [EMAIL PROTECTED] wrote: Create one.

help on my query statement
I have a table called TRANSACTION, it has some fields : REGDATE - date of the transaction WHAT - a string (NOT UNIQUE) CUSTOMER - customer code I want to query all WHAT that the date of the transaction was 15 days before. So, my sql query is : SELECT WHAT FROM TRANSACTION WHERE REGDATE Now() -INTERVAL 15 DAY But, because of WHAT is not unique, then I could receive some duplicates (customer can send some WHAT in the same REGDATE). How can I query only the unique WHAT ? I need to list all WHAT (uniquely) that the date transaction was 15 days before. Please help, Thanks __ Do you Yahoo!? Protect your identity with Yahoo!

updating some records in a table
Hi, I am new to mySQL, so I need some help. I have a table, which has record structure like this: - customer - name - register_date - expired Every day, I add some records, new customers. The field 'expired' is just a flag, either '1' or '0'. If register_date is 3 months ago then expired = 1. The format of register_date is unixtime, or Epoch. How can I update the entire database, for setting the expired field ? now = current_unixtime(); threemonths = 3 * 30 * 24 * 60 * 60; select * from table_name where register_date + threemonths now How to construct the proper select statement ? I use VARCHAR for register_date. select for i = 0 to number_of_rows do update table_name set expired = 1; I just could not think how to implement this. I need some example code how to update some records in table like in my situation. I use C ... or Perl Thanks. __ Do you Yahoo!? Yahoo! Mail Plus - Powerful. Affordable.

closing database (mysql C API)
Hi,
I wrote an application using mysql C API.
If I exit my application without closing database, will it be closed automatically?
void error(int code) {
printf(error: %d\n, code);
exit(0);
}
int main() {
...
error(-255);
...
}
How to pass the mysql database connector to a function? is this correct? :
void error(int code, MYSQL db) {
mysql_close(db);
printf(error: %d\n, code);
exit(0);
}
Because I am not sure this will be correct ... should not it using pointer?
Thanks.

updating a field more than once
Hi, I wrote a simple CGI application using mysql. What it does is really simple : connect to mysql database ... do something ... update a field ... do something again ... close mysql The update is like TOTAL = TOTAL + AMOUNT. If let say, 1000 users accessing my CGI in the same time, will it be OK ? will the update process be corrupted? should I implement LOCKING? I am new to mysql. Thanks, kapot __ Do you Yahoo!? Yahoo!

restricting mysql
Hi, After I installed mysql, I noticed there is an open port now, port 3306. Can I restrict this so only from localhost can connect? I meant to close port 3306. But without using firewall :( I dont have knowledge about this. If there is no way to do this without firewall, then I will learn it. I tried --skip-networking, but then mysqld could not be started. I got this from google.com. Is it the correct way? Thanks. kapot __ Do you Yahoo!? Yahoo!
