Question

I’m attempting to pull some data from a SQLite database so that I can populate a GridView in my GUI: here is the code that returns the DataTable:

DataTable table = new DataTable();

SQLiteDataAdapter adapter = new SQLiteDataAdapter(this.command.CommandText, this.connection);
adapter.Fill(table);

return table;

For some reason after calling adapter.Fill, the DataTable is still not populated with anything. So far I’ve verified that the command text is correct and that the connection contains the correct connection string. Both are used successfully in other parts of the application. No exceptions seem to be thrown… Is there any place else I should be looking for trouble? Am I using the API incorrectly?

Thanks!

Answer 1

This looks like correct usage.

One thing to check — after the fill you say the datatable is not populated. Were you just checking Rows.Count? What about columns? If the Fill creates columns to match your SELECT statement, but there aren’t any rows, then you know the code is working but there’s a problem with either your query, or you’re not hitting the same database you think you are.
