    <p>I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong.</p> <p>The program outputs: </p> <pre><code>Num rows loaded is 83 Num rows updated is 0 </code></pre> <p>The source code is: </p> <pre><code>public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } </code></pre> <p>Any hints on why it's not updating the correct number of rows?</p> <p><strong>Update:</strong> </p> <p>I tried to set the command before calling update and I'm still getting the same issue... the code is now: </p> <pre><code>sqliteAdapter.InsertCommand = cmndBldr.GetInsertCommand(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); </code></pre> <p>When I debug it the command text is: <code>_commandText = "INSERT INTO [Tags] ([tagId], [tagName], [description], [colName], [dataType], [realTime]) VALUES (@param1, @param2, @param3, @param4, @param5, @param6)"</code></p> <p>Here is a pastie showing the state of dataset in xml format: <a href="http://pastie.org/936882" rel="nofollow noreferrer">http://pastie.org/936882</a></p>

    1. COIs it possible that you have not set the InsertCommand sql, and params? Have a quick look at http://www.devart.com/dotconnect/sqlite/docs/Devart.Data.SQLite~Devart.Data.SQLite.SQLiteDataAdapter.html

    2. CO@astander I thought that the SQLiteCommandBuilder will do that based on this example http://dotnetperls.com/sqlcommandbuilder-example and this example http://www.devart.com/dotconnect/sqlite/docs/Devart.Data.SQLite~Devart.Data.SQLite.SQLiteCommandBuilder.html

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
