试图更新SQL Server CE失败

Question

我有我的SQL Server CE数据库的插入工作正常，但我很努力地更新。

有人能看到什么错什么，我想

using (SqlCeConnection con = new SqlCeConnection(ConfigurationManager.ConnectionStrings["MyConnection"].ConnectionString)) 
{ 
    con.Open(); 
    // Insert into the SqlCe table. ExecuteNonQuery is best for inserts. 
    string sql = "UPDATE SalesAssistant SET " 
      + "(Name=@Name,IsEnabled=@IsEnabled,Role=@Role,LastModifiedDate=@LastModifiedDate,IsAdministrator=@IsAdministrator,PIN=@PIN,IsDeleted=@IsDeleted)" + 
      "WHERE SalesAssistantID=@SalesAssistantID"; 

    using (SqlCeCommand com = new SqlCeCommand(sql, con)) 
    { 
     com.Parameters.AddWithValue("@SalesAssistantID", em.ServerData.EmployeeID); 
     com.Parameters.AddWithValue("@Name", em.ServerData.EmployeeName); 
     com.Parameters.AddWithValue("@IsEnabled", em.ServerData.IsEnabled); 
     com.Parameters.AddWithValue("@LastModifiedDate", em.ServerData.LastModifiedDate); 
     com.Parameters.AddWithValue("@IsAdministrator", em.ServerData.IsAdministrator); 
     com.Parameters.AddWithValue("@IsDeleted", em.ServerData.IsDeleted); 
     com.Parameters.AddWithValue("@Role", em.ServerData.Role); 
     com.Parameters.AddWithValue("@PIN", em.ServerData.PIN); 
     com.ExecuteNonQuery(); 
    } 
} 

我收到以下错误：

There was an error parsing the query. [ Token line number = 1,Token line offset = 27,Token in error = (]

Answer 1

周围的SET列表中删除括号，即

string sql = "UPDATE SalesAssistant SET " 
+ "Name=@Name,IsEnabled=@IsEnabled,Role=@Role,LastModifiedDate=@LastModifiedDate,IsAdministrator=@IsAdministrator,PIN=@PIN,IsDeleted=@IsDeleted" + 
" WHERE SalesAssistantID=@SalesAssistantID";
