Each entry in an SQLite table has a unique integer key. (The key is
the value of the INTEGER PRIMARY KEY column if there is such a column,
otherwise the key is generated at random. The unique key is always
available as the ROWID, OID, or _ROWID_ column.) This routine
returns the integer key of the most recent insert in the database.
Each entry in an SQLite table has a unique integer key called the "rowid".
The rowid is always available as an undeclared column
named ROWID, OID, or _ROWID_.
If the table has a column of type INTEGER PRIMARY KEY then that column
is another an alias for the rowid.
This function is similar to the mysql_insert_id() function from MySQL.
This routine
returns the rowid of the most recent INSERT into the database
from the database connection given in the first argument. If
no inserts have ever occurred on this database connection, zero
is returned.
If an INSERT occurs within a trigger, then the rowid of the
inserted row is returned by this routine as long as the trigger
is running. But once the trigger terminates, the value returned
by this routine reverts to the last value inserted before the
trigger fired.
