如何解决SQLLite“没有这样的表”错误？

Question

Overview: I'm using SQLLite to query an existing database in a Windows Phone 8.1 solution. I've adapted this solution to read the database data back to my project. But when I call ToList() using the DB connection I get a no such database error .

So far I've attached the database file and my DBHelper class uses the following code to query the data back:

        using (var dbConn = new SQLiteConnection(dbPath))
        {
            //No such table error thrown here ->
            List<ZoneInfo> zoneInfo = dbConn.Table<ZoneInfo>().ToList<ZoneInfo>();
            ObservableCollection<ZoneInfo> zoneInfoCollection = new ObservableCollection<ZoneInfo>(zoneInfo);
            return zoneInfoCollection;
        }

This is the complete DBHelper class which reference the existing DB file from my solution and copies it to the device's local folder. The DB file itself is here .

Debugging steps:

• I reviewed the ZoneInfo class properties to check that they match with the type/name each field in the DB schema below, and they match.
• The dbPath name matches the attached database name so that's not the issue either.
• I also found a similar question related to SQLLite on Android which suggests it could be an issue with my query on the table.
• I also inspected the dbconn variable and it shows me more info on the error:

Question:

What steps should I take to debug the SQLLite "no table" error further?

Exception Detail: The exact detail of the exception is as follows which tells me there is no such ZoneInfo table:

DB Schema:

DB Location in solution:

Answer 1

According to your github repo your dbpath represents just the relative path right Databases/DublinCityCouncilTable.db . Now for creating your connection you would need to provide the absolute path to your copied datatbase which would be

using (var dbConn = new SQLiteConnection(Path.Combine(ApplicationData.Current.LocalFolder.Path,@"Databases\DublinCityCouncilTable.db"), true))
