Sq-lite Query does not fetch all rows from Database
1
I am using Sqlite with WPF.
i face an issue that not all rows shows in the search query.
let's say i have 4 rows like below:
SQLiteConnection m_dbConnection;
m_dbConnection = new SQLiteConnection("Data
Source=SGenDB.sqlite;Version=3;MultipleActiveResultSets=true;");
m_dbConnection.Open();
SQLiteCommand commandM = new SQLiteCommand(m_dbConnection);
// sqlM
commandM.CommandText = "select * from TModels where PID=@Pid";
commandM.Parameters.AddWithValue("@Pid", "bb18a0d3-9dd3-4f20-a182-b90f8b79fbc2");
SQLiteDataReader readerM = commandM.ExecuteReader();
readerM.Read();
while (readerM.Read())
{
//DataGrid Binding
DG_LoadProject.ItemsSource = readerM;
}
The query return just one row always, the first row always being ignored.
I try in another data sample which has 4 rows and query returned just 3.
I create the database in the app first launching.
wpf sqlite

Remove the first call to readerM.Read() line. This is reading the first row but not doing anything with it.
So the code should be:
SQLiteConnection m_dbConnection;
m_dbConnection = new SQLiteConnection("Data
Source=SGenDB.sqlite;Version=3;MultipleActiveResultSets=true;");
m_dbConnection.Open();
SQLiteCommand commandM = new SQLiteCommand(m_dbConnection);
// sqlM
commandM.CommandText = "select * from TModels where PID=@Pid";
commandM.Parameters.AddWithValue("@Pid", "bb18a0d3-9dd3-4f20-a182-b90f8b79fbc2");
SQLiteDataReader readerM = commandM.ExecuteReader();
while (readerM.Read())
{
//DataGrid Binding
DG_LoadProject.ItemsSource = readerM;
}
