嘗試從MySqL服務器內部連接數據庫時出現錯誤。MySQL中INNER JOIN的語法錯誤
我得到這個錯誤:
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'lines INNER JOIN snippets ON snippets.id = lines.snippetid_fk WHERE lines.snippe' at line 1
即時通訊編碼在ASP.Net C#。
這是我的函數給出了錯誤:
MySqlConnection conn = new MySqlConnection();
string mysql = "Server=***;Database=***;User=***;pwd=***";
conn.ConnectionString = mysql;
MySqlCommand cmd = new MySqlCommand();
cmd.CommandText = "SELECT * FROM lines " +
"INNER JOIN snippets ON snippets.id = lines.snippetid_fk " +
"WHERE lines.snippetid_fk = 1";
cmd.Connection = conn;
DataTable dt = new DataTable();
MySqlDataAdapter adapter = new MySqlDataAdapter(cmd);
adapter.Fill(dt);
Repeater_codebank.DataSource = dt;
Repeater_codebank.DataBind();
你是什麼系的架構和摘要表? snippetid_fk是該表中的一列嗎?也許你需要用方括號包裝所有的對象名稱? 'SELECT * FROM [lines] l INNER JOIN [snippets] s ON(s.id = l.snippetid_fk)WHERE l.snippetid_fk = 1' –
@MohamedNuur - 方括號絕對不會幫助。 MySQL使用反引號。但是你基本上是正確的,'lines'是一個[保留字](http://dev.mysql.com/doc/refman/5.5/en/reserved-words.html),所以需要劃界。 –
如果您嘗試直接在查詢窗口中運行SQL,會發生什麼情況? – 5arx
