linux 下链接mysql练习

编译命令如下

hzz@hzz-pc:~/code/testCode$ g++ -I /usr/include/mysql/ /home/hzz/code/testCode/connect2.c -L /usr/lib/mysql -lmysqlclient -o connection2

hzz@hzz-pc:~/code/testCode$ ./connection2

#include <stdlib.h>
#include <stdio.h>
#include "mysql.h"

int main(int argc,char *arg[])
{
MYSQL myconnection;
mysql_init(&myconnection);
if(mysql_real_connect(&myconnection,"localhost","test","test","testDb1",0,NULL,0))
{

printf("connection success");
mysql_close(&myconnection);
}
else
{
fprintf(stderr,"connection failed\n");
if(mysql_errno(&myconnection))
{
fprintf(stderr,"Connection error %d %s",mysql_errno(&myconnection),mysql_error(&myconnection));
}
}

return 0;
}
