Insert null in Sqlite table

Question

I am trying to figure how to insert a null value into an SQLite table in Android.

This is the table:

\"create table my table (_id integer primary key         


        

Answer 1

In your insert query string command, you can insert null for the value you want to be null. This is C# as I don't know how you set up database connections for Android, but the query would be the same, so I've given it for illustrative purposes I'm sure you could equate to your own:

SQLiteConnection conn = new SQLiteConnection(SQLiteConnString()); 
// where SQLiteConnString() is a function that returns this string with the path of the SQLite DB file:
// String.Format("Data Source={0};Version=3;New=False;Compress=True;", filePath);

try 
{
    using (SQLiteCommand cmd = conn.CreateCommand()
    {
        cmd.CommandText = "INSERT INTO MyTable (SomeColumn) VALUES (null)";
        cmd.ExecuteNonQuery();
    }
}
catch (Exception ex)
{
    // do something with ex.ToString() or ex.Message
}
