SQLiteException: duplicate column name: Id #30
Description
void Start()
{
// 1. Create a connection to the database.
// The special ":memory:" in-memory database and
// URIs like "file:///somefile" are also supported
var db = new SQLiteConnection($"{Application.persistentDataPath}/MyDb.db");
// 2. Once you have defined your entity, you can automatically
// generate tables in your database by calling CreateTable
db.CreateTable<Player>();
// 3. You can insert rows in the database using Insert
// The Insert call fills Id, which is marked with [AutoIncremented]
var newPlayer = new Player
{
Name = "gilzoide",
};
Debug.Log("before insert Id=" + newPlayer.Id);
db.Insert(newPlayer);
Debug.Log("after insert Id=" + newPlayer.Id);
Debug.Log($"Player new ID: {newPlayer.Id}");
// Similar methods exist for Update and Delete.
// 4.a The most straightforward way to query for data
// is using the Table method. This can take predicates
// for constraining via WHERE clauses and/or adding ORDER BY clauses
var query = db.Table<Player>().Where(p => p.Name.StartsWith("g"));
foreach (Player player in query)
{
Debug.Log($"Found player named {player.Name} with ID {player.Id}");
}
// 4.b You can also make queries at a low-level using the Query method
var players = db.Query<Player>("SELECT * FROM Player WHERE Id = ?", 1);
foreach (Player player in players)
{
Debug.Log($"Player with ID 1 is called {player.Name}");
}
// 5. You can perform low-level updates to the database using the Execute
// method, for example for running PRAGMAs or VACUUM
db.Execute("VACUUM");
}
Hello, I found a problem. After building and running the above example on an Android device, starting from the second launch, an exception is thrown: “SQLiteException: duplicate column name: Id.”.
