Question

我通过article创建了一个FTS 我有一个varbinary（max）类型的列，我填充了MSWord文件（.doc）和另一个类型为word的列（由.doc填充）。当我运行此脚本时，输出为空

SELECT 
    name,
    content
FROM tblWordFiles 
WHERE FREETEXT(content, '1');

或

SELECT 
    name,
    content
FROM tblWordFiles 
WHERE contains(content, '1');

我的问题在哪里？

OOOOOOO！我用这段代码来填充数据库（c＃）

    SqlConnection cn = new SqlConnection(@"Data Source=MJ;Initial Catalog=Test_word_binary;Integrated Security=True");
    string command = "insert into tblWordFiles (type,content) values('doc','@c')";
    SqlCommand cm = new SqlCommand(command, cn);
    DialogResult dg = openFileDialog1.ShowDialog();
    if (dg == DialogResult.OK)
    {
        // Create a new stream to load this photo into
        System.IO.FileStream stream = new System.IO.FileStream(openFileDialog1.FileNames[0], System.IO.FileMode.Open, System.IO.FileAccess.Read);
        // Create a buffer to hold the stream bytes
        byte[] buffer = new byte[stream.Length];
        // Read the bytes from this stream
        stream.Read(buffer, 0, (int)stream.Length);
        // Now we can close the stream
        stream.Close();

        cm.Parameters.Add("@c", SqlDbType.VarBinary).Value = buffer;
        cn.Open();
        cm.ExecuteNonQuery();
        cn.Close();
    }

Answer 1

您引用了参数@c，因此将其作为文字值而不是参数的值插入。

请参阅：insert into tblWordFiles (type,content) values('doc','@c')

应该是：insert into tblWordFiles (type,content) values('doc',@c)

我不确定类型列是否包含'。'或者不是'.doc'或'doc'

FTS使用故障
