Question

I am using csharp-sqlite library.

The code:

var conn = new SQLite.SQLiteConnection(DatabasePath);
conn.Execute("insert or replace into Option(Key, Value) values ('A', '1')");
conn.Execute("insert or replace into Option(Key, Value) values ('B', '2')");

It works as I expect. However when I use BeginTransaction() and Commit, I get an exception in the second Excute: “CannotOpen”, the native is SQLITE_CANTOPEN (error 14).

The code would be:

var conn = new SQLite.SQLiteConnection(DatabasePath);
try
{
  conn.BeginTransaction();
  conn.Execute("insert or replace into Option(Key, Value) values ('A', '1')");
  conn.Execute("insert or replace into Option(Key, Value) values ('B', '2')");
  conn.Commit();
}
catch (SQLiteException ex)
{
     _conn.Rollback();

}

What am I doing wrong?

Thank you

I got this problem when running on WinRT.

This pragma fix the issue :

using(var connection = new SQLiteConnection(dbPath))
{
   connection.Execute(string.Format("PRAGMA temp_store_directory = '{0}';", Windows.Storage.ApplicationData.Current.TemporaryFolder.Path));
}
