把mysql.h复制到vc的目录的include目录下
mysql.h在你mysql的安装目录下的include里面如:mysql\include
把libmysql.lib(在mysql的安装目录下，搜索下就能找到）复制到这个目录下（C:\Program Files\Microsoft Visual Studio 9.0\VC\lib），要不连接会出错。
如果编译连接时还是出错。就把libmysql.lib复制到你源程序的目录中
（示例1)、
// TODO: Add your control notification handler code here
char *query;
int t,r;
MYSQL_RES *res;
MYSQL_ROW row;
m_mysql = mysql_init(NULL);
if (!mysql_real_connect(m_mysql,"localhost","databasename",
"yourdatabase-password","yourtable",0,NULL,0))
{
CString errors =mysql_error(m_mysql);
MessageBox(errors,"´íÎó");
}
query="select text from yourtable";
t=mysql_real_query(m_mysql,query,(unsigned int) strlen(query));
if(t)
{
MessageBox(mysql_error(m_mysql));
}
res=mysql_use_result(m_mysql);
row=mysql_fetch_row(res);
CString sumstr;
for(r=0;r<=mysql_field_count(m_mysql);r++)
{
if(row<0)
{
MessageBox("error");
}
for(t=0;t<mysql_num_fields(res);t++)
{
CString Query = row[t];
sumstr+=Query+" ";
}
}
MessageBox(sumstr);
mysql_close(m_mysql);
}
（示例2）、
#include "winsock.h"
#include "mysql.h"
int main(int argc, char* argv[])
{
MYSQL * con = mysql_init((MYSQL*) 0);
LPSTR host = "***";
LPSTR user,psw,dbname,;
if ( con !=NULL
&& mysql_real_connect(con,host,user,psw,dbname,3306,NULL,0) )
{
if (!mysql_select_db(con,dbname))
{
printf("Select successfully the database!\n");
con ->reconnect = 1;
if (!mysql_query(con,"select * from table_name"))
{
printf("Show table---orders:\n");
MYSQL_RES * recordSet = mysql_store_result(con);
long j = mysql_num_fields(recordSet);
long i = (long)mysql_num_
