当用户输入时,我需要我的文本框自动完成.该值应来自数据库.我正在使用文本框的textchange属性.

protected void autocomplete(object sender, EventArgs e)
{
    string query = "Select area,codes from tbl_pincode";
    SqlConnection conn = new SqlConnection("Data Source=win2008-2;Initial       Catalog=h1tm11;User ID=sa;Password=#1cub3123*;Persist Security Info=True;");
    SqlCommand com = new SqlCommand(query, conn);
    conn.Open();
    SqlDataReader dr = com.ExecuteReader();
    while (dr.Read())
    {
        zipcode.Text = dr.GetValue(0).ToString();
    }
    conn.Close();
}

但我没有得到理想的结果.任何想法如何去做？

我有一张桌子:

1. user_id int Composite Unique (deal_id + user_id+deal_type).
2. deal_id int
3. deal_type varchar.
4. created_on datetime.

这是我的桌子.我想在user_id列上创建唯一的复合,以便单个用户只能deal_id为每个用户创建唯一的deal_type.

如何在mysql phpmyadmin中创建复合唯一.

我在数据库中有两个列类型和名称.我想应用一个唯一约束,其中每个类型的名称都是唯一的.

Type   Name
 A     ABC
 R     ABC
 B     ABC

应该允许,而

Type  Name
 A    ABC
 A    ABC

不应该被允许

如何强制执行此约束,其中name在每种类型中都是唯一的？

谢谢,

我正在使用sql server.我有一张桌子

Company
 ABC
 XYZ
 ABC,XYZ

当我运行一个类似的查询时,where company like '%ABC%'我得到的记录只包含ABC而不是ABC,XYZ

如何获得这两个记录？

我想将tabhost的默认蓝色更改为红色.
