I'm using sqlite database for my C# Form application. For example code I used this and yes, I added SQLite.NET to refrences.
using Finisar.SQLite;
// [snip] - As C# is purely object-oriented the following lines must be put into a class:
// We use these three SQLite objects:
SQLiteConnection sqlite_conn;
SQLiteCommand sqlite_cmd;
SQLiteDataReader sqlite_datareader;
// create a new database connection:
sqlite_conn = new SQLiteConnection("Data Source=database.db;Version=3;New=True;Compress=True;");
// open the connection:
sqlite_conn.Open();
// create a new SQL command:
sqlite_cmd = sqlite_conn.CreateCommand();
// Let the SQLiteCommand object know our SQL-Query:
sqlite_cmd.CommandText = "CREATE TABLE test (id integer primary key, text varchar(100));";
// Now lets execute the SQL ;D
sqlite_cmd.ExecuteNonQuery();
// Lets insert something into our new table:
sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (1, 'Test Text 1');";
// And execute this again ;D
sqlite_cmd.ExecuteNonQuery();
// ...and inserting another line:
sqlite_cmd.CommandText = "INSERT INTO test (id, text) VALUES (2, 'Test Text 2');";
// And execute this again ;D
sqlite_cmd.ExecuteNonQuery();
// But how do we read something out of our table ?
// First lets build a SQL-Query again:
sqlite_cmd.CommandText = "SELECT * FROM test";
// Now the SQLiteCommand object can give us a DataReader-Object:
sqlite_datareader=sqlite_cmd.ExecuteReader();
// The SQLiteDataReader allows us to run through the result lines:
while (sqlite_datareader.Read()) // Read() returns true if there is still a result line to read
{
// Print out the content of the text field:
System.Console.WriteLine( sqlite_datareader["text"] );
}
// We are ready, now lets cleanup and close our connection:
sqlite_conn.Close();
Everything works great when database in created in runtime, but when I try to open an existing database created in SQLiteStudio I get exception unsupported format. When I opet this database.db in SQLiteStudio and only add data new data, its fine after I run the program again. My goal is to be able to create database and export it from studio and just to call it in my code with ofcourse "New=False" and other modifications
