解析查詢時發生錯誤。 [令牌行號= 1，令牌行偏移= 59，令牌在錯誤=用法]

Question

當我插入在表中的數據是給我錯誤

public int SolveSection(string sectionName, string userid, string examId, string TotalSolveQuestion, string time) 
{ 
    SqlCeCommand cmd = new SqlCeCommand(); 
    int a = 0; 
    Random rnd = new Random(); 
    _connection.Open(); 

    cmd.Parameters.Add(new SqlCeParameter("@User_id", userid)); 
    cmd.Parameters.Add(new SqlCeParameter("@Exame_id", examId)); 
    cmd.Parameters.Add(new SqlCeParameter("@Interactive usage of English_Solve_Total_qouation", TotalSolveQuestion)); 
    cmd.Parameters.Add(new SqlCeParameter("@Interactive usage of EnglishT", time)); 
    cmd.Parameters.Add(new SqlCeParameter("@Interactive usage of English", sectionName)); 

    cmd.Connection = _connection; 
    //cmd.CommandText = "Insert into [Personal_information_ofcandidat](User_id,Name,MName,LName,Exam_date,Exam_id,College_Name,Email_id,Phone_no) values('" + userid + "','" + uname + "','" + muname + "','" + luname + "','" + DateTime.Now + "','" + examid + "','" + collegname + "','" + email + "','" + mobile + "')"; 

    cmd.CommandText = "Insert into [Solve_Question](user_id,Exame_id,Interactive usage of English_Solve_Total_qouation,Interactive usage of EnglishT,Interactive usage of English)" + "values(@User_id,@Exame_id,@Interactive usage of English_Solve_Total_qouation,@Interactive usage of EnglishT,@Interactive usage of English)"; 

    cmd.CommandType = CommandType.Text; 

    try 
    { 
     a = cmd.ExecuteNonQuery(); 

     if (a > 0) 
     { 
     } 
     else { userid = ""; } 
     _connection.Dispose(); 
    } 
    catch (Exception ee) { } 

    return a; 
} 

它給我一個錯誤消息：

分析查詢時發生錯誤。 [令牌行號= 1，令牌行偏移= 59，令牌出錯=使用] 在行ExecuteNonQuery（）行。我錯在哪裏。

Answer 1

從列名稱和參數名稱中刪除空格，並且如果要列名稱和空格，然後將它們放入[column Name]。

cmd.Parameters.Add(new SqlCeParameter("@User_id", userid)); 
cmd.Parameters.Add(new SqlCeParameter("@Exame_id", examId)); 
cmd.Parameters.Add(new SqlCeParameter("@Interactive_usage_of_English_Solve_Total_qouation", TotalSolveQuestion)); 
cmd.Parameters.Add(new SqlCeParameter("@Interactive_usage_of_EnglishT", time)); 
cmd.Parameters.Add(new SqlCeParameter("@Interactive_usage_of_English", sectionName)); 

cmd.Connection = _connection; 
//cmd.CommandText = "Insert into [Personal_information_ofcandidat](User_id,Name,MName,LName,Exam_date,Exam_id,College_Name,Email_id,Phone_no) values('" + userid + "','" + uname + "','" + muname + "','" + luname + "','" + DateTime.Now + "','" + examid + "','" + collegname + "','" + email + "','" + mobile + "')"; 

cmd.CommandText = "Insert into [Solve_Question] (user_id,Exame_id,[Interactive usage of English_Solve_Total_qouation],[Interactive usage of EnglishT],[Interactive usage of English])" + "values (@User_id,@Exame_id,@Interactive_usage_of_English_Solve_Total_qouation, @Interactive_usage_of_EnglishT,@Interactive_usage_of_English)";
