UWP 包装 sqlite 插入查询到 sql 事务

Question

我正在尝试将一些 csv 样式 file.txt 内容插入本地 SQLite 数据库，我处理文件读取、内容处理并获取一些字符串：

INSERT OR REPLACE INTO mytab (id,name,adress) VALUES(1,john,adress1)
INSERT OR REPLACE INTO mytab (id,name,adress) VALUES(2,marry,adress2)
INSERT OR REPLACE INTO mytab (id,name,adress) VALUES(3,lama,ruadress3)
//...

现在我想打开一个 sqlite 事务，执行所有这些插入，然后关闭事务。我正在使用 SQLite.Net-PCL 和 SQLite for Universal App Platform，我该怎么做？

我尝试打开这样的连接：

var sqlpath = Path.Combine(ApplicationData.Current.LocalFolder.Path, "Mydb.sqlite");
SQLiteConnection conn = new SQLiteConnection(new SQLitePlatformWinRT(), sqlpath);

//I'am trying to open transaction - but get ERROR -> SQLiteCommand does not contain contstructor that takes 2 arguments
 SQLiteCommand cmd = new SQLiteCommand("BEGIN", conn);

Answer 1

SQLite.Net-PCL中的SQLiteConnectionclass有BeginTransaction、Commit和Rollback方法，所以你可以在BeginTransaction和提交：

// Open connection
SQLiteConnection conn = new SQLiteConnection(new SQLitePlatformWinRT(), sqlpath);
try {
   // Start transaction
   conn.BeginTransaction();
   try {
      // Execute commands...
      // Commit transaction
      conn.Commit();
   }
   catch (Exception) {
      // Rollback transaction
      conn.Rollback();
   }
}
finally {
   // Close connection
   conn.Close();
}
