SQLite
This is available using the SQLite last_insert_rowid()
function:
The last_insert_rowid() function returns the ROWID of the last row
insert from the database connection which invoked the function. The
last_insert_rowid() SQL function is a wrapper around the
sqlite3_last_insert_rowid() C/C++ interface function.
PHP
The PHP version/binding of this function is sqlite_last_insert_rowid()
:
Returns the rowid of the row that was most recently inserted into the
database dbhandle, if it was created as an auto-increment field.
