Mysql 插入中文及中文查询 (修改+调试)


//我修改之,能正常运行,测试环境为mysql5.0,xp
//关键是设置对字符集,设置gbk,gb2312测试通过,utf8测试未通过
//在运行程序前先建立数据库jj,注意下面几个参数(修改为你自己的)

复制代码 代码如下:

// char *host = "localhost";
// char *user = "root";
// char *pass = "674800";
// char *db = "jj";
#include <windows.h>
#include <iostream>
#include <mysql.h>
#include <stdio.h>
#include <string.h>
using namespace std;
#pragma comment(lib,"libmysql.lib")
int connDB();
int create_table();
int insert_table();
int select_table();
int disconnDB();
MYSQL *mysql;
MYSQL_RES *res;
MYSQL_FIELD * fd;
MYSQL_ROW row;
char szSqlText[500]="";
int i;
int main()
{
connDB();
// create_table();
insert_table();
select_table();
disconnDB();
return 0;
}
///////////////子函数
int connDB()//连接数据库
{
char *host = "localhost";
char *user = "root";
char *pass = "674800";
char *db = "jj";
mysql = mysql_init((MYSQL*) 0);
mysql_real_connect( mysql, host, user, pass, db,3306, NULL, 0 ) ; //链接到服务器
mysql_set_character_set(mysql,"gb2312"); //设置字符集
cout<<"conn OK!"<<endl;
return 0;
}
//关闭数据库
int disconnDB()
{
mysql_close( mysql ) ;
cout<<"disconn OK!"<<endl;
return 0 ;
}
//创建表
int create_table()
{
mysql_set_character_set(mysql,"gb2312");
sprintf(szSqlText, \
"create table mytable \
(s0 varchar(100), \
s1 char(6),\
s2 varchar(4),\
s3 varchar(3),s4 int)\
ENGINE=InnoDB \
DEFAULT CHARSET=gb2312");
if(mysql_query( mysql, szSqlText))
cout<<"occurred an error:"<<mysql_error(mysql)<<endl;
return 0;
}
int insert_table()
{
mysql_set_character_set(mysql,"gb2312");
sprintf(szSqlText,
"insert into mytable\
values('2000-3-10 21:01:30',\
'Test',\
'清风寒剑',\
'岁月情',\
2500)");
if( mysql_query( mysql, szSqlText) )
cout<<"occurred an error:"<<mysql_error(mysql)<<endl;
return 0;
}

{

mysql_close( mysql ) ;
return FALSE ;
}
res = mysql_store_result( mysql) ;
i = (int) mysql_num_rows( res ) ;
cout<<"Query: "<<szSqlText<<"\n"<<i<<" records found:"<<endl;
for ( i = 0 ; fd = mysql_fetch_field( res ) ; i++ )
cout<<fd->name<<"\t";
cout<<endl;
while(row = mysql_fetch_row( res ))
cout<<row[0]<<"\t"<<row[1]<<"\t"<<row[2]<<"\t"<<row[3]<<"\t"<<row[4]<<endl;
mysql_free_result( res ) ;

}
