Question

我正在制作一个押韵词典，我有一个包含3个coloumns的数据库表，用户将搜索数据库，搜索关键词将搜索数据库，其中单词的结尾与文本框中的单词匹配。

当我在文本框中输入一些关键字时

我收到错误：关键字'LIKE'附近的语法不正确。

以下是我的aspx的样子：

这是我的aspx.cs

    }

    SqlConnection cnn = new SqlConnection("Initial Catalog=kafiyedizini;Data Source=localhost;Integrated Security=SSPI;");

    protected void Button1_Click(object sender, EventArgs e)
    {
        if (TextBox1.Text != "")
        {
            cnn.Open();
            SqlCommand cmd = new SqlCommand("SELECT kelime1,kelime2,kelime3 FROM kelimeler LIKE @arama", cnn);
            cmd.Parameters.AddWithValue("@arama", "%" + TextBox1.Text);
            SqlDataReader dr = cmd.ExecuteReader();
            if (dr.HasRows)
            {
                while (dr.Read())
                {
                    resultbox1.InnerHtml += dr.GetString(0);
                    resultbox2.InnerHtml += dr.GetString(1);
                    resultbox3.InnerHtml += dr.GetString(2);
                }
            }

            cnn.Close();
        }
        else
        {
            resultbox1.InnerHtml += "please enter data";
        }
    }
}

Answer 1

您缺少部分SQL查询

示例：

SELECT * FROM test WHERE test.Id LIKE '%asd%'

我也认为，dr.Read（）执行PER ROW。

希望这有帮助

Answer 2

您问题中的初始sql语句应如下所示

SELECT kelime1,kelime2,kelime3 FROM kelimeler where kelime1 LIKE @arama OR kelime2 LIKE @arama or kelime3 like @arama

你错过了你想要在你的声明中使用的地点和字段。

将每个结果放在一个单独的框中＆＃39;您可以更好地研究GridView的工作方式或DataRepeater。

最初的代码中最接近的可能是什么，包括支持处理返回字段的null / emtpy值，很好地填充3个结果框：

        var f1 = dr.GetString(0);
        var f2 = dr.GetString(1);
        var f3 = dr.GetString(2);
        if (!String.IsNullOrEmpty(f1)) 
            resultbox1.InnerHtml += String.Format("<div>{0}</div>",f1);
        if (!String.IsNullOrEmpty(f2)) 
            resultbox2.InnerHtml += String.Format("<div>{0}</div>",f2);
        if (!String.IsNullOrEmpty(f3)) 
            resultbox1.InnerHtml += String.Format("<div>{0}</div>",f3);

无法显示结尾匹配的结果
