in reply to Last Insert ID in MS Access

The following example works for me. Applicable versions are shown inline:

use strict; use warnings; use DBI; #MS Access 2003 #DBI->installed_versions; # Perl : 5.008008 (MSWin32-x86-multi-thread) # OS : MSWin32 (5.0) # DBI : 1.59 # DBD::ODBC : 1.13 # Connect to the db my $dbpathfile = 'C:\testdb.mdb'; my $db_driver = 'Microsoft Access Driver (*.mdb)'; my $dsn = "DBI:ODBC:DRIVER=$db_driver;DBQ=$dbpathfile"; my $dbh = DBI->connect( $dsn, '', '', { RaiseError => 1, AutoCommit => + 1 } ) or die $DBI::errstr; # Create table for test data my $tblname = 'test_table'; my $tbl_sql = join( ' ', 'CREATE TABLE', $tblname, '(ID AUTOINCREMENT, field1 TEXT,', 'CONSTRAINT', $tblname . '_pk', 'PRIMARY KEY +(ID))' ); $dbh->do( $tbl_sql ); # Insert test data my $insert_sql = join( ' ', 'INSERT INTO', $tblname, '( field1 ) VALUE +S ( ? )' ); my $sth = $dbh->prepare( $insert_sql ); $sth->execute( 'test data' ); # Use @@IDENTITY to get the last insert ID # See http://support.microsoft.com/kb/815629 my $id_sql = 'SELECT @@IDENTITY'; $sth = $dbh->prepare( $id_sql ); $sth->execute; my $id = $sth->fetchrow_array; print "Last insert ID is: $id\n";

Thanks to james2vegas and his post for seeding this approach. Thanks also to mje for considering adding this example to the docs for DBD::ODBC.
