Question

在monotouch应用程序中，我使用此代码插入一个值：

string sql = "insert or ignore into [translation] values (\"7d8281e2-3f0d-4f51-a6bd-bf91af90dc4a\",\"113a1275-e7a0-452d-a1e1-9043c1139584\",\"1\",\"Gömlek\")";
var cmd = _repository.Execute(sql);

其中repository是扩展SQLiteConnection的类的实例。这个确切的语句在RazorSql中完全正常。但是当我用我的代码执行它时，它给了我：

SQLite.SQLiteException: near ""Gömlek"": syntax error
  at SQLite.SQLite3.Prepare2 (IntPtr db, System.String query) [0x0001b] in /Users/serhat/Projects/MyApp.Mobile/trunk/MyApp.Mobile.iOSApp/Database/SQLite.cs:1564

并且异常实例不包含其他信息。我错过了什么？

编辑：我认为这与字母“ö”有关。当我用“o”替换它时，查询工作正常。如何使用unicode字符？

参数化查询解决了问题。

insert or ignore into [tablename] values (?,?,?,?,?)

SQLite语法错误，它不应该
