AutoIncrement Int PK doesn't Increment through DapperLite?

[RefractedPaladin]

Any ideas? I have the table set right and if I use straight SQL it works correctly but once I use DapperLite, like below, it only gives Id a value of 0.
this.CurrentPunch = new Punches(){ PunchTime = DateTime.Now, Method = "PIN"};
db.Insert(CurrentPunch);

In SqlMapper.cs I tried adding the following to the AddParams() as a HACK way of getting around this but to no avail as I simply get an exception stating "Insufficient number of parameters supplied" so I'm guessing I need to find where I'm getting the values or columns. Also, now that I'm typing all this out it occurs to me that if I did this it would break 'Update' as it uses that method as well?

private static void AddParams(IDbCommand cmd, object data)
{
if (cmd == null || data == null) return;

IEnumerable<string> propertyNames = GetParamNames(data);
foreach (string propertyName in propertyNames)
{
// I added this if()
if (propertyName == "Id")
continue; .......

Well, I'm a little ashamed to admit this but I got it 'working' doing the following.
In SqlMapperInsertUpdate.cs, the Insert() I added the following two lines right before the Execute()

sql = sql.Replace("@Id,", string.Empty); sql = sql.Replace("Id,", string.Empty);

@RefractedPaladin One other solution is having a Punches class you use for inserts that doesn't have an Id property. That way they query builder won't pick up the field and try to insert it.

The other thing you could try is making Id nullable in the model: http://stackoverflow.com/questions/11771166/how-do-i-get-dapper-rainbow-to-insert-to-a-table-with-autoincrement-on-sqlite

This should be a much better solution for you.

Ah, thanks. Tried the Id nullable thing and it seems to be working.

Follow up to this, or maybe it's really seperate, but is there a way to get the auto ID back from the Insert? Otherwise, I seem to be stuck writing code like so:
db.Insert(newEmp); newEmp.Id = db.Get<Employee>("PIN", newEmp.PIN).Id;

Where PIN is like a FK that is manually assigned though not guaranteed to be unique.

Great question! It should be possible. We'll see what we can do

Clearly this won't work for you but I took a look at Dapper.Rainbow and what they were doing which was basically a SELECT scope_identity() so I tried to model after that. I didn't have a ton of time and what I have works but is specific to having "Id" as the PK. What can I say but "Works For Me!" :)

I'd be interested in writing/seeing a better, more generic solution though. Mines below just in case you were curious.

var id = connection.Query<Int64?>("SELECT MAX(Id) AS Id FROM " + tableName); return id.FirstOrDefault();

and then of course changing the signature of both Insert() from void to Int64? though I suppose I could also use long?

Looks like this could help you out:
