如果用sqlite3_get_table()取出一个结果集，那么有时候很想打印出来看一下，随手写了一个，记录起来以备不时之需。

int print_data(char **rs,int *row,int *col)
{
    int i = 0;
    int irow = *row;
    int icol = *col;
    char **irs  = rs;
    int itotal = (irow+1) * icol;
    YY_LOG(YY_NOTICE,"row[%d],col[%d],total[%d]\n",irow,icol,itotal);
    for (i = 0; i < itotal; i++) { //
        printf("[%s]",irs[i]);
        if(0 == (i+1)%icol) { printf("\n"); } //gives every row of record a ENTER symbol
    }
    return 0;
}
static char *g_sql      =   NULL; //存储sql语句
static int g_return     =   0; //保存sqlite3_xxx的返回值
sqlite3 *db_handle      =   NULL; //数据库联接
static char *err_msg    =   NULL; //错误原因
static char **g_rs      =   NULL; //结果集
static int  g_row       =   0; //取出行数
static int  g_col       =   0; //取出列数

int main ()
{
    g_sql = sqlite3_mprintf("SELECT * FROM table_1");
    g_return = sqlite3_get_table(db_handle,g_sql,&g_rs,&g_row,&g_col,&err_msg);
    
    print_data(g_rs,&g_col); //调用实例

    sqlite3_free_table(g_rs);
    sqlite3_free(g_sql);
    return 0;
}
