So, if someone could enlighten me as to the defined behavior of
sqlite3_last_insert_rowid with regards to transactions, I would be most
grateful.
The last insert id is a property of a connection. So there is no way
that one connection can accidently get the last row inserted by
another connection.
But when is the ROWID generated? Is it generated when the INSERT is
evaluated/executed, or when it is committed?
Take the following scenario:
Conn 1: BEGIN TRANSACTION
Conn 1: INSERT...
Conn 1: sqlite3_last_insert_rowid()
Conn 2: INSERT... (same table as Conn1 just did)
Conn 2: COMMIT
Conn 1: COMMIT
Now, who got the "next" ROWID? Conn 1 or Conn 2? What did
sqlite3_last_insert_rowid() return to Conn 1?
I'm sorry if I'm being dense; I'm just trying to understand the exact
behavior in this case.
